How to use a water heater correctly: operating instructions for flow and storage units

How to turn on the water heater

The sequence of actions to turn on the Thermex boiler:

• It is necessary to shut off the hot water supply to the riser. This is one of the essential rules on how to properly use a heating device.If you have a non-return valve, you still need to close it, since its breakdown, which you may not immediately know about, will lead to the fact that you will provide hot liquid to all neighbors in the riser.
• Fill the tank with water, to do this, open all the valves on the boiler (cold inlet and hot outlet at the boiler). Open any faucet in the apartment in order for air to escape from the tank, this moment will come when liquid flows from the tap.
• Then connect to the mains. After 15-20 minutes, check if the liquid is heating up.

When you turn it on for the first time, you must set the water heating temperature in the range of 70-75 degrees.

What to do if the water in the boiler has an unpleasant smell

If you use the water heater intermittently, the liquid in the boiler may stagnate and an unpleasant odor will appear. Stagnant water is a favorable environment for the active reproduction of bacteria, their vital activity is a source of a rotten smell.

In order to get rid of an unpleasant odor, you need to take the following measures:

• completely drain the stagnant liquid from the boiler;
• fill the tank with clean water;
• set the maximum heating value;
• leave the boiler on for a couple of hours;
• drain the hot water and refill the tank.

After this procedure, the unpleasant odor will disappear.

In addition to bacteria, the materials from which the machine is made can be a source of unpleasant odors. If you use a water heater made from low-quality plastic, then during the heating process, the plastic will begin to release harmful substances such as formaldehyde or phenol. As a result, the heated liquid will give off the smell of medicines.Unfortunately, to solve this problem, you need to replace the device. Filters will not be able to purify water from formaldehyde compounds.

Boiler Advantages

Hot water in the house is not a luxury at all, but a necessary condition for comfort. However, residents of city apartments often face the fact that during the summer period hot water is disconnected from the centralized supply for repair work. This forces many people to install boilers - containers that allow water to be heated and used in the local plumbing system.

The advantage of heaters of this type is that they can be installed in almost any, even the smallest room. Modern models consume little electricity, which saves the family budget. And the most important plus is that there will always be a supply of hot water in the house.

Rules for the operation of the water heater

Regular operation of the storage water heater implies a constant connection to the electrical network. So the device will have the opportunity, when cooling, to heat the water to the set temperature without significant energy costs. At the same time, the filled tank is less exposed to the corrosive process.

If the boiler is constantly turned off, savings cannot be achieved, because the equipment spends more electricity to heat the liquid. Shutdown is possible with rare use (once a month).

The disconnected device must not be left in an unheated room if the temperature in it drops below +5⁰ C. When choosing heating equipment for a summer residence, this fact must be taken into account.

When switching on the operating mode, it is necessary to check the presence of water inside the tank. Otherwise, the water heater will immediately fail.

Expert answers

Fursov Yuri:

It may well be that the tena has a shell pierced

Zaretskii Kostya:

A leak. Check the integrity of the heating element - drain the water, unscrew and visually inspect. If there are obvious cracks, the replacement will solve everything. If the heating element is intact and in good condition, and the magnesium cathode is also in good condition, then it’s already more difficult. If there are electrical measuring instruments, you can see the presence of leakage current, if you know how to use them. No - consult with knowledgeable people.

BASIL:

a lot is how much? the water heater has an indication when the heating element is turned on and heats up, if you drain the water every half an hour, then it will continue to heat until the temperature set by you is reached, the boiler cannot take more than 1.5 kW alone, and the meter winds well, how much according to you, it’s a lot, 500-1000-2000 kW, you didn’t write, but if he works constantly, I think he alone will burn at least 150-200 kW, plus more appliances in the house at least 100-150 kW

Alexei:

So you heat 65 liters of water with a power of 2500W all day long, which you do not consume, it heats up, cools down and heats up again. And you use 15 liters from a can. 50 liters work for heat loss, efficiency 20-25%.

It is logical for you to buy a heater of such volume, how much hot water you spend during the period of intensive water withdrawal.

For example, 30 liters or even 10. For example, with a programmable function "memory for daily consumption by time of day." The heater will prepare water for you in the morning, at lunchtime and for dinner. the rest of the time it is disabled.

Small load sinks. Leave the big 65 for the shower and turn it on separately.

Small from Ariston you can buy 20 liters with two cans of 10 and two alternately turned on tenami 2500 for each can. Boiling water for half an hour.

Programmable with memory now from 8 and above.

Well, of course, the calculation is correct only if the equipment is in good condition. RCD performance.

Mr.Androws:

Water heater: .vensys /catalog/detail.php?ID=2535 off - enabled.

Nikolay Kros:

So what's the problem? Plug it in and everything. Judging by the button and the regulator, everything is on. on- enable; off-switch off. Why is the water shut off? And is it even with water? If it was turned on without water, the heating element could burn out.

Free wind:

And what's so difficult? We supply cold water to the valve with a valve, from the other valve it goes to the apartment system of mountains. water, while the inlet valve must naturally be closed (you are not going to give hot water to the whole house?) ....))))))))))))))))))

Rules for using the storage water heater

Scheme of an electric instantaneous water heater.

The storage water heater is distinguished by the fact that in its design it contains a sufficiently capacious water tank in which it is gradually heated. Electricity or a gas burner can be used to heat water. How to properly use a storage water heater?

Firstly, it must be installed correctly, taking into account the recommendations for choosing its location, methods of fastening. Since the storage tank is designed for a fairly large volume, fastening should be carried out only on load-bearing walls and with the help of special fasteners, which, as a rule, are supplied with the kit.

Secondly, it is necessary to correctly carry out its first start after installation and connection to the water supply system. The first start-up of the storage water heater is carried out in the following sequence:

1. The correct connection to the heating system is checked. If an electric water heater is used, then you should check the correct connection of the mains, the phasing, the presence of a protective switching device - a circuit breaker. Before starting the boiler, its power supply must be turned off. If gas heating is used, check the elements of the system for connecting to the gas pipeline.
2. Check whether the work on connecting to the water supply system has been carried out correctly, that there are no water leaks. Availability and serviceability of the back pressure valve. Only after checking, they start filling the water heater tank with cold water.
3. In order to properly fill the water heater, the hot water tap is first opened. By the appearance of water from an open hot water tap, you can determine the full filling of the tank.
4. After filling the tank, once again check the absence of water leaks in the system and start the heating system. It is not recommended to set the maximum heating mode when you first turn it on - this can lead to failure of the thermostat or temperature sensors.

How to use the device correctly if it is already turned on?

Water supply installation.

There are no special comments on this subject, the prerequisites are that:

• it is not recommended to disconnect the water heater from electric current during its operation;
• You can turn off the heater after heating the water in case of energy savings and if hot water is not needed for a long time.

The requirements for using a storage water heater also include:

• preliminary check of the water level in the tank;
• presence of grounding.

Electric water heaters must be grounded to prevent electric shock during operation and maintenance. If the heating element is damaged, the water will be under current and when the hot water is turned on, a person may be exposed to the current. It is much safer to use such a device.

Features of Thermex water heaters

Water heater Tthermex ER 80 V

The Tthermex ER 80 V water heater is a reliable source of hot water. The electric storage boiler performs heating in advance, the residents have the opportunity to use hot water at any time. For increased safety, the device is equipped with an emergency shutdown system.

Design

The storage electric water heater of a simple design allows you to quickly diagnose and troubleshoot in time. The device consists of several parts:

• Cold water enters the device through a special pipe located at the bottom of the device. It is connected to a cold water supply system (CWS) in an apartment or to a pipe coming from a well in a private house. The pipe is equipped with a valve that prevents hot water from flowing back into the cold water system.
• A pressure switch is located on the cold water pipe, which regulates the rate of water inflow and prevents damage to the device.
• After the relay, the water enters a large tank of eighty liters, made of copper. Outside the tank there is a layer of heat-insulating material that prevents the rapid cooling of water.
• Inside the tank is a heating element (TEN). Its operation is regulated by a manual thermostat located on the instrument panel. With its help, the owners independently set the temperature to which it is necessary to heat the water.
• Some models of heaters are equipped with a silver anode that disinfects water.
• At the top of the tank there is a thermal fuse that regulates the heating. When the water reaches the set temperature, the heating element stops its work and turns off. When the water in the tank cools, it starts functioning again. The fuse prevents water from boiling, a sharp increase in pressure in the tank and the destruction of the water heater.
• When a hot water tap is opened, the contents of the tank are vented to the outside through an outlet pipe connected to the domestic hot water network.

In addition to the main elements for heating water, the device is equipped with a terminal, block and clamp. They provide a safe connection of the product to the electrical network.

The device is equipped with several sensors. The green light on the panel lights up when the heating is completed. The thermostat is located at the top of the tank. It controls the process of heating water, a light bulb is connected to it, which turns on when the heating element starts to work and turns off when the required temperature is reached.

Advantages

Location of controls on device

People often choose one of Thermex water heater models 80 liters. This is the best option for most families. Advantages:

• Works from an electric network. Far from all private sectors and dacha cooperatives have gas, but electricity is everywhere. A water heater can be connected to any home.
• The volume of 80 liters is designed for a family of three showering one after another.
• Connects to three plumbing fixtures at once, providing hot water for showers and a couple of sinks in the kitchen and bathroom.
• Allows you to heat water in advance, and during the day just maintain its temperature.This will ensure uninterrupted operation of the DHW.
• Water heats up in just 2 hours 10 minutes.

The combination of positive qualities makes the product a popular equipment for providing private houses and apartments with hot water.

materials

One of the important advantages of Thermex water heaters are the materials from which they are made. Strength, durability and ease of use depend on their combination. The devices are made of high-quality materials that are resistant to mechanical damage and attractive in appearance:

• polished stainless steel;
• low carbon steel;
• high strength plastic.

The storage tank is made of stainless steel with the addition of titanium. This protects the tank from corrosion and prolongs its service life.

To increase energy efficiency and reduce the cost of maintaining a high water temperature, the space between the tank and the outer walls is filled with a material with low thermal conductivity - polyurethane.

Briefly about the device and the principle of operation

In order to save money, users try to turn on the boiler according to a certain schedule. But if you want to reduce energy consumption during the operation of a water heater, you need to understand in general terms how it functions.

The picture below shows a storage boiler - an insulated tank made of stainless steel or enameled steel with a built-in tubular electric heater (heater) that has its own thermostat. At the bottom there are water inlet and outlet pipes, in the same place (or on the front panel) there is a heating regulator and a thermometer.

The main elements of the electric water heater

The water heater operation algorithm looks like this:

1. Through a branch pipe equipped with a check and safety valve, the container is filled with cold water.The heating element automatically turns on and the heating process begins.
2. When the contents of the tank reach the temperature set by the user, the thermostat turns off the electric heater. If there is no water intake, the automation maintains the heating at the set level, periodically turning the heater on and off.
3. When the DHW tap is opened on any mixer, water is taken from the upper zone of the tank, where the corresponding pipe is connected.

So that the electrochemical reactions that occur between dissimilar metals during the heating process do not cause corrosion of the steel container, a magnesium anode is built into it, which takes the “shock” on itself. That is, due to the activity of this metal, the rod is gradually destroyed instead of the tank and the heating element.

Regular cleaning of the water heater

As mentioned earlier, the boiler needs regular cleaning, which should be done at least once every two years. You can do it more often, in this case a lot depends on how hard the water is used. The boiler will clog faster if:

• well water is used;
• water does not meet the requirements for purity or hardness.

But these are very approximate data, because it was often necessary to clean the boiler two months after installation. It happens and vice versa - the device has been serving for ten years and is in excellent condition, without going through a single cleaning.

The boiler must be cleaned regularly

But there is no need to "go too far" in any case. Conduct a routine inspection a year and a half after purchase. If, when examining the boiler, you find that very little scale has formed, then the next cleaning can be carried out in a couple of years.But if the water began to heat up longer, and the device makes suspicious sounds during operation, this means that it's time to start cleaning immediately. In addition, if necessary, you can change the magnesium rod, and for this you need to know how to drain the water from the boiler.

Types of instantaneous water heaters

Instantaneous water heaters are divided according to the type of energy that is used for heating. Therefore, they can be divided into the following types:

• Electric, in which the passing water is heated by a heating element (tubular electric heater) or a metal tube, which is affected by an alternating magnetic field (inductor). Therefore, they are divided into two types: induction and heating elements. This type of water heater consumes electrical energy, therefore it is not suitable for places where it is impossible to connect to the mains;
• Water, working from the heating system. These devices do not require an electrical connection, so they can be used even in non-electric homes. However, dependence on the heating system does not allow their use in the summer;
• Solar, receiving heat from the luminary. They do not depend on the heating system or electricity, so they can be used in summer cottages. However, these devices heat water only on warm sunny days;
• Gas, powered by liquefied or main gas. Such devices are used only in houses and apartments connected to the central gas pipeline.

This device heats the flow of water passing through it.

The basis of an electric water heater is nichrome wire, which has a high resistance, wound on a ceramic frame.The induction heater works on a different principle. A thick copper bus is wound around a metal pipe, then high-frequency (up to 100 kilohertz) voltage is applied. The alternating magnetic field heats the metal pipe, and the pipe, in turn, heats the water. There are flow heaters that are built into boilers or heat accumulators filled with water. That is why they are called water. The best option for a summer cottage is a solar instantaneous water heater. It runs on solar energy and heats the water to 38-45 degrees, which is enough to take a shower. Gas instantaneous water heaters appeared in the student environment out of desperation caused by a broken column or other similar factors. They are a copper tube twisted into a spiral, located above the fire of a kitchen gas stove.

What can you do yourself

Before choosing a specific type of water heater, you need to determine what tools, materials and skills are available to you. If you know how to work well with a welding machine, you can make an electric water heater. If you already have a working heating system with a heat accumulator and you know how to use a welding inverter, you can make a water heater. If you do not have such talents or you do not have electricity or water heating, then a solar water heater is quite capable of you.

Gas instantaneous water heaters are a means of increased danger. To work with any gas devices, you must undergo special training, otherwise it is likely that instead of a tankless water heater you will get a time bomb that will explode one day.If the concentration of gas in the room is 2–15%, then an explosion will occur from any spark. Therefore, in this article there are no instructions with which you can create a gas instantaneous water heater.

To create most water heaters, you will have to learn how to use welding

Characteristics of flow and storage units

All water heaters according to the principle of water heating are divided into flow devices and storage models. Often the same company supplies both options to the market, and the buyer already has the right to choose what exactly he needs.

Storage devices are equipped with a container of a certain volume into which water is collected. After filling the usable volume of the device, it begins to heat up with specially designed heating elements to the temperature specified by the user in the settings.

Models offered in stores allow you to choose the optimal set of functions at an affordable price. The main thing is to decide in advance what is best for a particular house / apartment

The reservoir of such heaters is necessarily insulated, which contributes to the long-term preservation of the temperature of the water inside. Its volume can be from 10 to 300 or more liters.

Manufacturers foresee the demand for overall devices that can satisfy the needs for heating water for a large family.

The accumulative heater with a volume of 10 liters can be placed in any convenient place. For example, under the sink

The larger the volume of the storage device, the more space will be required to place it in a house or apartment. This fact must be taken into account.

The second type of water heaters for domestic use is flow-through.They differ significantly from accumulative ones - they do not have a reservoir for collecting a certain volume of liquid.

You may be interested in information about which type of water heater is better - flow or storage?

Flow models heat the water coming from the water pipe immediately after opening the tap. Visually, such models are much smaller and are mounted next to the crane.

A variety of instantaneous water heaters is a special tap. It does not require a lot of electricity and can be a real find for giving.

Depending on the fuel consumed, most often storage and flow devices are:

The first have a large initial cost, but pay off in 2 years. The latter initially cost 2-3 times cheaper, but due to the high cost of electricity, already in the third year of use, they are more expensive for their owner.

This dependence is valid with constant use.

Flow models of heaters can be equipped with a kitchen spout, shower head. They are mounted next to the faucet to avoid large heat losses.

If we are talking about a seasonal stay in the country and the use of small volumes of warm water, then the electric option will come in handy for a potential buyer.

After all, electricity is supplied to many suburban areas, and as for gas, the situation with its availability can be more deplorable. Yes, and with rare use of the device, it will use up quite a bit of electricity.

Tips for choosing and installing a boiler

Savings in the case of this device begins at the installation stage.Before buying a storage water heater, choose the best place for it, which would be located close to the water intake points. The reason is that every meter of pipe is a loss of heat on the way to the faucet or shower head. For a pipe with a diameter of half an inch, the heat consumption is 0.2 liters of boiling water per 1 m when the tap is opened, and the same amount when the tap is closed.

When you start using the boiler, you first release lukewarm water. When closing the valve, leave the boiling water halfway in the pipe. It turns out that kilowatts for heating this water were wasted. The best place for a home with one kitchen and bathroom is to place the boiler somewhere in the middle between these rooms. Perhaps even closer to where you open the faucet more often.

Do not be discouraged if this condition is impossible for you. For example, a heater does not fit into the design of the room or is unacceptable in it from the point of view of common sense. Then it is quite possible to get by with additional insulation of the pipe through which the heated water passes. For this, for example, a polypropylene cover and special fittings are suitable.

When buying a storage heater, be guided, first of all, by its technical characteristics. Today there are many models, different power and performance. Try to find one that has a low energy rating. At the same time, it must meet your needs in terms of the amount and speed of heating water.

Characteristics and types

Flexible hose for plumbing is a hose of different lengths, made of non-toxic synthetic rubber. Due to the elasticity and softness of the material, it easily takes the desired position and allows installation in hard-to-reach places.To protect the flexible hose, the upper reinforcing layer is designed in the form of a braid, which is made of the following materials:

• aluminum. Such models withstand no more than +80 ° C and retain functionality for 3 years. In high humidity, aluminum braid is prone to rust.
• Of stainless steel. Thanks to this reinforcing layer, the service life of the flexible water supply is at least 10 years, and the maximum temperature of the transported medium is +95 °C.
• Nylon. Such a braid is used for the manufacture of reinforced models that can withstand temperatures up to +110 ° C and are designed for intensive use for 15 years.

Nut-nut and nut-nipple pairs are used as fasteners, which are made of brass or stainless steel. Devices with different indicators of permissible temperature differ in the color of the braid. The blue ones are used for cold water connections, and the red ones for hot water.

When choosing a water supply, you need to pay attention to its elasticity, reliability of fasteners and purpose. It is also mandatory to have a certificate that excludes the release of toxic components by rubber during operation.

Inclusion

The sequence of actions to turn on the Thermex boiler:

• It is necessary to shut off the hot water supply to the riser. This is one of the essential rules on how to properly use a heating device. If you have a non-return valve, you still need to close it, since its breakdown, which you may not immediately know about, will lead to the fact that you will provide hot liquid to all neighbors in the riser.
• Fill the tank with water, to do this, open all the valves on the boiler (cold inlet and hot outlet at the boiler). Open any faucet in the apartment in order for air to escape from the tank, this moment will come when liquid flows from the tap.
• Then connect to the mains. After 15-20 minutes, check if the liquid is heating up.
• When you turn it on for the first time, you must set the water heating temperature in the range of 70-75 degrees.

How to use instantaneous water heater

A tankless water heater has its advantages and disadvantages. The first include the fact that the use of such heaters does not limit your family in the amount of hot water consumption. You can even take turns swimming all day with the whole family. The inconvenience is the impossibility of simultaneously supplying hot water to several points of water intake. Yes, and with a strong pressure of water, it is difficult to achieve a high temperature of its heating, if there is no way to adjust the flow.

Instantaneous water heater

Particular attention should be paid to the installation of an instantaneous electric water heater. The high power of this device is based on the high power consumption

And in order to avoid overheating of the network, it is wiser to lay a separate wiring and for this it would be more correct to invite specialists. High-quality installation and proper connection of the water heater will protect your family from misfortune.

For efficient operation of the equipment and reduction of energy costs, you need to know how to use an electric water heater:

• Remember, the closer you place the water heater to the faucet, the less the water will cool down “on the way”.
• With increased water hardness, it is recommended to install special filters, so you will extend the life of the device.
• Flowing water heaters should not be left in rooms with negative temperatures, this leads to their damage and breakdowns.
• Turning on the instantaneous water heater, check the water pressure at the tap. With a low pressure, it is recommended not to set a high heating temperature, as the device may not turn on at all.

In order for household equipment to work efficiently for many years, it is necessary to follow the rules of use and maintenance. Our article, expert advice and operating instructions for an instantaneous water heater or boiler will help you with this.

According to the principle of operation, “flow-throughs” differ significantly from the boiler-type heaters. Their device is simple and does not require special attention.

However, the instantaneous water heater has individual disadvantages and advantages, which should be paid attention to during operation. The use of such devices removes the limitation on the volume of heated water. This is what attracts a consumer with a large number of family members.

However, such units are designed for 1-2 water intake points. With an increase in this number, the heating of hot water is not so high quality. According to the principle of operation, a new representative has appeared on the plumbing market - a water-heating faucet. The device is a faucet that is installed on the washbasin and uses all the functions of a flow heater.

With an increase in the power of the electrical protochnik, the risk of overheating of the electrical wiring inside the house increases. Therefore, take care to install a separate toggle switch for the instantaneous electric water heater in order to avoid a possible short circuit.

WATCH VIDEO

The following set of recommendations will increase the life of the device and increase its efficiency:

• The instantaneous water heater is recommended to be installed near a water tap. This will shorten the way hot water is delivered to the consumer, which has a positive effect on its temperature.
• If in the region where the installation of the "flow" is supposed to be, the water hardness is increased, then it is recommended to install a special fine filter in front of the device.
• The instantaneous water heater is not installed in rooms where the temperature is below 0C. Otherwise, the device will soon fail.
• Before turning on the electric water heater, make sure that there is sufficient pressure in the water supply network. If the pressure is weak, reduce the water heating temperature so that the device works in the correct mode.

The water heater can be accumulative and instantaneous, and then it's your choice.

What is a boiler

The storage electric water heater is a device that gives its users independence from the general heating system. In fact, it is like a large thermos, which provides long-term storage of the desired water temperature. All this happens thanks to the heat-insulating layer, however, there are other important components in the design of the unit:

• heating element (most often heating element);
• thermostat to adjust the water temperature;
• the container itself is in the form of a steel tank (enamelled from the inside).

That's just the tank and determines the cost of the device. If all other parts can be easily replaced, then in the event of a tank leak, it would be best to buy a new boiler.

Nuances of operation

Flow-type water heaters attract many consumers because they have no restrictions on the use of hot water volume, it is especially convenient to install it in a shower stall - take water procedures as much as you like.

Not everyone knows that the installation of such a device requires responsibility, because the product belongs to high-power devices, it requires the obligatory laying of a separate connection line. Installation of the line and connection of the product can only be carried out by specialists; with self-installation, you can de-energize not only your apartment, but also an apartment building.

In order for the instantaneous water heater to serve for a long time and not upset you with frequent breakdowns, you must strictly follow the manufacturer's recommendations and pay attention to such points:

• installation of the product should be done near the place of use to reduce heat loss;
• if there is very hard water in your area, install special protective filters to protect internal parts from scale;
• in no case do not install the product in an unheated cottage;
• in the bathroom, position the device in such a way that splashes cannot get on the body;
• at low pressure, use the product at an average temperature - otherwise the automation simply will not turn on.

Please carefully follow these steps before starting for the first time.

1. Check the presence of water in the home plumbing and the level of its pressure - it should be sufficient. With a weak pressure, you will have to abandon use until better times.
2. With low heating of the water flow, set the required temperature using the buttons on the control panel.
3. After taking a shower, the tap must be closed, the product must be disconnected from the mains.

Before you go to the store for a long-awaited purchase, check the quality of the wiring in the house: old houses are designed for only 3 kW / h per apartment, so you will have to change all the wiring to the electrical distribution panel to connect. Users who live in new high-rise buildings, and even with electric stoves, are lucky: here the tolerance for an apartment is higher and starts from 10 kW / h, but this does not mean that you can turn on several electrical appliances at once.

In conclusion, a few words about the domestic electric instantaneous water heater Etalon Copper 350 of the combined type: a faucet and a shower hose with a nozzle. The weight of the structure is only 2 kg, dimensions - 240x160x95, power up to 3.5 kW, maximum heating temperature of the water flow - 65C, productivity - 3.5 l / m. According to its characteristics, it is not inferior to foreign counterparts and is inexpensive - 2440 rubles, and in case of replacement it will be much easier to find components.

Conclusion

The selection of a boiler for heating water will depend on the conditions of use of this equipment and the capabilities of the buyer. When you need a solid system capable of heating large volumes of water, at a moderate cost of operation, then you need to make a choice in favor of storage devices. Those who need hot water in small quantities can purchase instantaneous boilers.

As with the use of any technique, the operation of a water heater requires compliance with certain requirements that are prescribed in the instructions for a particular device.Before starting the heater, it would be useful to study the instructions, which will make it possible to increase the life of the equipment, reduce the cost of its repair and save money that goes to pay.
