How to connect an Ariston water heater

To connect the Ariston boiler correctly, you must follow the manufacturer's instructions.

First, the water heater is mounted on a wall or supporting surface and the outlet (cold water) is provided from the water pipe. It is most beneficial to install the device as close as possible to the source of water supply - this allows you to minimize heat loss.

If there is a collector in the system, a separate cold water supply pipe is transferred to the installation site of the water heater. If there is no collector, the nearest section of the water pipe is cut, and a standard tee is installed at the cut site.

The method of installing the tee depends on the material from which the pipes are made. Plastic fasteners are fastened using a special soldering iron, and metal ones are fastened with threads.

A ball valve is installed in a separate section of the water supply system, designed to shut off the cold water supply.

To connect the water heater to the water supply:

1. Pay attention to the hot and cold water pipes - it is important not to confuse them. A check valve is installed on the cold side; it can be included in the standard kit. Hot water is connected using a pipe. First, a cold water pipe is installed, then a hot one.
2. A special tape is wound onto the threads as a sealant and sealant; this is recommended by the manufacturer.
3. A tee is installed on the cold water pipe, at the bottom of which there is a relief valve. A tap is attached to the side to completely drain the water from the tank in case of an emergency, possibly due to abnormal pressure or heating. A shut-off valve and adapter are installed at a short distance under the tee. The next step is connecting to the water supply.
4. Connection to hot water is also made by installing a shut-off valve.
5. When connecting different metals, adapters should be used.

Connection to the electrical network is carried out as follows:

1. A separate circuit breaker (RCD) is installed in the distribution panel; it is connected to the central automatic fuse. A three-core cable is pulled from a separate RCD to the boiler, which is placed in an external cable channel (or a special groove is punched into the wall).
2. It is recommended to install a 16 A fuse as a switch, since the socket and plug are subject to heat and moisture. In addition, the cost of waterproof electrical equipment is higher than the cost of a machine. The “switch” is closed in a compact cabinet with a removable panel.
3. A separate RCD and the “switch” are connected by wire.
4. A three-wire wire is connected to the heating element; for this, the bottom panel is removed from the water heater.
5. Then the output of the machine is connected to the boiler.
6. At the next stage, the ground, phase and zero lines are wired to the corresponding connectors.

Before turning on the device, you must make sure that there are no leaks and that the flange is in the correct position (strictly in the middle). Then fill the tank with cold water and open the hot water tap to release the air. After bleeding the air, the valve is closed and a test operation is performed.

More detailed advice and instructions for operation and installation can be obtained from the KVANTA+ company in Tyumen.

Under what conditions should the device not be installed?

Electrical appliances, in particular an electric water heater, must be installed in conditions that correspond to those specified in the instruction manual.

The following are stated in the instructions for Ariston boilers as unacceptable factors for installation:

• frost - this is associated with the risk of freezing water in the tank and pipes;
• sunlight - do not expose the electric heater to direct sunlight;
• power outages - the voltage in the network to which the device is connected must be stable;
• vapors, dust or gas - the water heater must not be installed in a room with a high concentration of dust and toxic or acidic gases/vapors in the air;
• dampness - it is not recommended to install the device in conditions of constant dampness and in long-term unventilated rooms (this item depends on the degree of moisture resistance of the selected water heater model).

What you need to know about Ariston boilers

The main function of Ariston water heaters is to provide houses, apartments, cottages, and cottages with hot water supply for household purposes. In order for the electric water heater to serve for a long time and with high quality, the following characteristics were observed:

• the internal tank is made of high-quality anti-corrosion material - stainless steel, the internal walls of the water heating tank are coated with a special coating to prevent plaque formation;
• High efficiency heating element with reliable insulation;
• internal dividers that do not mix cold water with heated water;
• intelligent control system;
• overheating protection using control sensors;
• high-quality thermal insulation allows you to maintain the water temperature for a long time;
• the presence of a professional antibacterial coating;
• ease of use.

It should be noted that the instructions for water heater models that differ only in the system of different volumes of the same series are almost identical. There are two types of heaters based on the principle of operation: flow-through (the heat exchanger heats the temperature instantly as soon as you open the tap) and storage (water is drawn into the tank and then heated). Storage water heaters, or boilers, have a compact tank designed for different volumes - 30, 50, 80, 100 liters. Boilers can be directly heated (they heat the water themselves using gas or electricity) and indirect (such devices are located near a heat exchanger, for example, a boiler).

Installation of the device must be carried out by a specialist, otherwise your equipment will lose the right to warranty service. After installing an electric water heater, check the following:

• Are there any water leaks: to do this, disconnect the water heater from the network and turn on the cold water filling;
• At the same time, we also turn on the hot water tap to see when the boiler is completely filled. As soon as warm water flows from the tap, the boiler is completely filled with water. Close the tap and check the boiler itself to see if there is any dripping from the connections.
• Only after you are sure that there is no leakage, insert the water heater plug into the network and select the desired heating mode.

About installing an Ariston electric water heater according to instructions

Before installing the water heater, make sure the wiring can handle the added power. It is especially important that the outlet you are going to connect the device to is grounded and not exposed to water. Power to the water heater must come from the panel via a separate cable . When choosing a place to install an electric water heater, take into account its triple weight with water and the strength of the walls.

For fastening, hooks of at least 15 mm in size are required. It is recommended to install the water heater in close proximity to the dispenser, which will also reduce heat loss when supplying water to the point of disassembly. The distance from the ceiling is at least 10 cm, the space around the device is within a radius of at least 50 cm for technical work.

Under what conditions should the device not be installed?

If the water is hard, you must additionally install a filter, otherwise the water heater will quickly fail. Do not install the device in rooms where the temperature may be below freezing; avoid exposure to factors dangerous to the device - dampness, frost, direct sunlight, dust and insects. Avoid splashes of water as much as possible from entering the body of the device, that is, it is not recommended to install it directly above the bathtub.
If the water pressure is low, it is necessary to set the maximum temperature mode, otherwise the device may not turn on at all.

Brand name parts only

All parts of the water heater must be in good working order when first installed. This is especially true for the safety valve. If damage is noticeable, the part should be replaced with a similar one. Do not use adapters or extension cords under any circumstances, or replace the water heater plug with another one. A separate power line to power the boiler is required. If the power cord is damaged, replace it with a similar one.

When disconnecting the electric heater, use a two-pole switch, the gap between open contacts is from 3 mm. Also note that the pipes to which the water heater connections will be connected have withstood temperatures exceeding 80 degrees Celsius and the maximum operating pressure.

Precautionary measures

If you know you won't be using the appliance for a while, simply drain all the water from it. To do this, turn off the power to the device, close the cold water supply valve at the water heater, and open the hot water tap on the mixer. Open the drain valve of the tee. The magnesium anode, which will be used up over time, should be replaced with a similar one. The first start-up of the device should be carried out strictly according to the instructions.

Ariston water heater repair

Scale on the heating element.
Ariston water heaters are reliable household appliances, but they are also susceptible to some malfunctions. The most common are the appearance of scale on the heating element, failures in the electronic control unit and low pressure when supplying water to the tank.

For repairs, it is preferable to use the services of professionals. Guidance and advice on these issues can be obtained from KVANTA+.

How to identify a malfunction

To carry out repair work, the user must notice a malfunction in the operation of the water heater in time. Ariston boilers are often equipped with an electronic display on which messages appear in the event of equipment failures.

Direct signs of a malfunction may be:

• the machine is triggered when the boiler is turned on - this indicates a malfunction of the heating element;
• heating water above the maximum permissible temperature - this indicates a failure of the thermostat;
• heating of water below the required values ​​- this may indicate contamination of the heating element, the appearance of scale;
• drips in the lower part of the tank and on its walls;
• breakdown of the information display, which most often does not cause significant disruptions in the overall functionality of the device, but can reduce comfort during its use.

An indirect sign can be considered extraneous noise during operation of the electric heater.

To install wall-mounted models, the equipment is fixed using anchors or bolts. The optimal standard fastener diameter should be 10 mm or more . Installation of hundred-liter water heating tanks has some features. In this case, the fastening must be carried out with fixation on the other side of the wall. It is for this reason that experts recommend installing water heating devices before starting the main finishing work.

It is important to remember that when connecting different types of metals, it is mandatory to use dielectric adapters, through which differences in the degree of expansion of materials differing in parameters are compensated. The input must be connected using a standard valve, and a pipe is installed at the output. At the final stage, the installed water heater must be turned on and checked for correct connection, absence of leaks and operability.

During the operation of manufactured water heaters, difficulties do not arise, but it is necessary to take into account some rules that affect the durability of the device and its performance. Preventive measures are carried out periodically, including inspection of the internal parts of the equipment, descaling and replacement of heating elements that have become unusable. The average operating time of all mechanisms of a particular model can be found from the manufacturer's instructions. It must be remembered that timely replacement of the anode allows you to extend the service life of the water heating mechanism. In accordance with the recommendations of professionals, it is not advisable to set the thermostat to the maximum heating level.

If you set the temperature limit approximately 10°C below the maximum values, you can significantly reduce electrical energy costs, as well as save resources on equipment parts. It is important to remember that you can only disassemble the device yourself as a last resort. Do-it-yourself repair work will exclude the possibility of exercising the right to warranty repairs.
