DESCRIPTION AND PRINCIPLE OF OPERATION

The outside casing of the EWH is made of impact-resistant plastic. Inner tanks have a special bio-glass-porcelain coating reliably protecting the inner surface against chemical corrosion. The space between the outside casing and the inner tanks is filled with polyurethane foam – a modern, ecologically clean thermal insulation, which has the best heat-saving characteristics. These models have two screwed nozzles: for inlet of cold water (Figure 1, p. 3) with a blue ring and for outlet of hot water (Figure 1, p. 2) — with a red ring, and equipped with an additional drain connection (closed with metal plug button) for draining the water and flushing the inner tank (Figure 1, p. 17). The control panel, in all models, is on the front side of the EWH (Fig. 1, p. 16).

Tubular electric heater (TEH), thermostat and thermal switch sensors are mounted on the removable flange. TEH is used to heat water and is controlled by thermostat which has smooth temperature regulation adjustment up to +75°С. All models are controlled with electronic monitoring panel. Electronics maintain automatically water temperature at the level set by the user. The thermostat is used for protecting against EWH overheating, which disconnects TEH from power supply when water temperature exceeds 95°С. (Fig. 3).

Safety valve (Fig. 1, p. 5) operates as the check valve, ensuring protection of the water ingress from the water heater into the sewage system in case of pressure drop in the sewage system and in case of pressure rise in the tank at high water heating, as well as the functions of the safety valve, releasing overpressure in the tank at high water heating. During water heater operation water may leak out of the exhaust outlet pipe of the safety valve to relieve excessive pressure, which is made for the purpose of water heater safety. This outlet pipe shall remain open to the atmosphere and be installed constantly down and in a non-freezing environment.

Drainage of water from the safety valve (Fig. 1, p. 14) exhaust pipe into the drain shall be provided with installation of the corresponding EWH drainage (Fig. 1, p. 6).
It is required regularly (at least once a month) to discharge a small amount of water through the exhaust pipe of the safety valve into the drain to remove lime deposits and to test the operating functionality of the valve. Handle (Fig. 1, p. 15) is intended to open the valve. It is necessary to control when operating water heater this handle to be in position closing water draining from the tank.

SPECIFYING SECURITY MEASURES

Electrical safety and corrosion protection of EWH are guaranteed only if there is an effective grounding in accordance with applicable electric installation rules and regulations.
Plumbing pipes and fittings shall conform to parameters of water main and have the required certificates of quality.

When installing and operating EWH the following is not allowed:

To power EWH if EWH is not filled with water.
To remove the protective cover when the power is on.
Use EWH without grounding.
To connect EWH to water supply with pressure exceeding 0.7 MPa.
To connect EWH to the water supply without safety valve.
To drain water from EWH with power switched on.
To use spare parts not recommended by the manufacturer.
To use water from the EWH for cooking.
To use water containing impurities (sand, small stones), which might lead to EWH and safety valve breakdown.
To modify design and installation dimensions of EWH brackets.

Ambient temperature shall be within the range of 3ºС to 40ºС. Water in freezing EWH at negative temperatures results in malfunction, which is not a warranty case.

Attention should be paid to children so that they do not play with EWH. EWH is not intended for use by persons (including children) with limited physical, sensory or mental capabilities, or by persons who do not know how to use the EWH, except for cases when this happens under the supervision or instructions by persons responsible for safety of the EWH.

It is recommended to install EWH as close as possible to the place of hot water using to reduce heat loss in the pipes.

When drilling (making) holes in the wall consider cables, ducts and pipes in the wall. When choosing the place of installation total weight of EWH filled with water shall be taken into account. Walls and floor with low carrying capacity should be strengthened accordingly.

EWH is suspended by brackets on hook anchors fixed in the wall. Hooks mounting on the wall shall exclude spontaneous movement of EWH brackets along them.
For EWH maintenance the distance from the protective cover to the nearest surface in the direction of the removable flange axis shall be at least 30 cm for all models.

In order to avoid damage of the user’s and/or third parties’ property in the event of a faulty hot water system, it is required to install EWH in spaces with waterproofing and drainage to the sewers, and in no case to place under items exposed to the water under EWH. When placed in unprotected areas a protective plate (not supplied) with drainage into sewers shall be installed under the EWH.

In case of placing EWH in hard-to-reach places EVN in order to perform maintenance and warranty service (mezzanine floors, niches, ceiling voids, etc.), installation and dismantling of EWH is carried out by the user on his own or for his own account.

Note: safety tray is not included into the scope of EWH supply.

CONNECTION TO WATER MAINS

Install pressure relief valve (fig. 1, p.5) at the cold water inlet (fig. 1, p. 3) tube with the blue ring, by 3.5-4 turnings, ensuring junction tightness with any sealing material (flax, FUM tape, etc.).

Do not operate the EWH without safety valve or with valve made by other manufacturers.

During EWH operation you can observe water leak out of the outlet pipe of the safety valve for excessive pressure release to ensure safety of the water heater. It is recommended to connect to a drainage hole a rubber or silicone pipe of the relevant diameter for moisture removal.

Connection to the water supply line shall be carried out in accordance with Fig. 1 using copper, plastic pipes or special flexible sanitary wiring. Do not use any used flexible wiring.

EWH switching on/off is made by control panel button “On/Off” (Figure 2, p.1).

In the course of EWH operation the user can regulate heating temperature using button “Temperature” (Figure 2, p. 2). The following values may be taken as target temperature: 55°С, 65°С, 75°С (Figure 2, p. 3). When choosing temperature the heating temperature indicator flashes 5 times, then switches into operating mode. When water temperature is lower than the set temperature, EWH heats water, and heating temperature indicator flashes. When water temperature reaches set value, heating temperature indicator is permanently on. When water heater is on, its target temperature is 65℃.

Using smart mode button “Smart” (Figure 2, p.4) EWH smart operation mode can be enabled. In this operation mode EWH can study and record user’s habits in using hot water and prepare hot water in advance for the next water cycle (7 days in a cycle). When users do not need hot water, it can maintain water at minimum temperature. Thus comfort and saving of energy can be achieved. This mode is used for those who use hot water on a regular basis. To enable this mode, press smart mode button “Smart”. To disable the mode, press this button again or switch EWH off.

Frost protection mode “NO FROST”. When EWH is plugged, but switched off using “On/Off” button, and water temperature is less than 5 ℃ the frost protection mode is automatically enabled. When water temperature reaches 10 ℃ the frost protection mode is automatically disabled. When frost protection mode is enabled, power indicator is on.

If you do not use the EWH in the winter time and there is a possibility of freezing of the main waterways and the water heater itself, it is recommended to turn off the power and drain the water from the EWH in order to avoid damage to the inner tank.

TECHNICAL MAINTENANCE

Maintenance and timely replacement of magnesium anode are obligatory conditions for long-term operation of EWH. Failure to comply with these requirements is grounds for release from the warranty service. Maintenance and replacement of magnesium anode are not part of the warranty of the manufacturer.

When performing maintenance condition of magnesium anode and scale on TÈH are checked. At the same time residue that may accumulate in the bottom of the EWH is removed.

Magnesium anode must be replaced at least once in 2 years. If water contains high levels of chemical contaminants, the magnesium anode must be replaced more often. Scaling at TEH can result in its malfunction, that is not a warranty case, and its replacement is not included in the warranty of the manufacturer and the seller. If there is scale on TEH, then it can be removed by using scale removing means or mechanically. When removing residuals from EWH do not apply excessive force and do not use abrasive cleaners not to damage the protective coating of the inner tank.

Importance of the first maintenance is that by intensity of scale and residues, magnesium anode consumption terms for next maintenance services can be decided and, consequently, service life can be extended. In case of non- observance of the above requirements EWH service life reduces, increases the probability of EWH breakdown and validity of warranty expires.

Scale accumulated in the course of operation on TEH may cause its damage

Note: Damages to TEH due to scale formation are not subject to warranty. Regular maintenance is not included in the warranty of the manufacturer and the seller.

The following shall be carried out for maintenance:

Turn off EWH power;
Cool hot water or discharge it through the mixer;
Cut off supply of cold water into EWH;
Unscrew the relief valve or open drain valve;
To put on the cold water supply inlet or discharge valve a rubber hose, sending the other end down the drain;
Open hot water tap on mixer and drain water from the EWH through the hose;
Remove the protective cover, disconnect wires, unscrew and remove from the casing the removable flange;
Clean if necessary THEs from scale and remove residue from the tank;
Assemble, fill the EWH with water and power on.

In models with drain pipe, it is enough to cut off the flow of cold water into the EWH, unscrew the drain stub on drain pipe and open hot water tap. Once the water is discharged, you can open for a while cold water supply in EWH for additional tank washing.
When conducting EWH maintenance by forces of specialized organization mark with the seal of organization performing maintenance shall be made in service coupon.
