4. DESCRIPTION AND PRINCIPLE OF OPERATION

The outside casing of the EWH is made of steel. 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 tank is filled with polyurethane foam

- a modern, ecologically clean thermal insulation, which has the best heat-saving char-

acteristics. Vision 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. The

control knob, in all models, is on the bottom side of the EWH. (Figure 1, p. 16).

Tubular heating element (THE), thermostat and thermal switch sensors are

mounted on the removable flange. THE is used to heat water and thermostat provides

with possibility of heating temperature regulation up to +75°С.

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 wa-

ter 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 in-

stalled constantly down.

Drainage of water from the safety valve exhaust pipe into the drain shall be pro-

vided with installation of the corresponding EWH drainage.

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.

5. 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 regula-

tions.

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 or use water pipes as grounding.

•To connect EWH to water supply with pressure exceeding 0.75 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 5ºС 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.

During EWH operation, it shall be inspected regularly for proper health (absence

of dripping, burning smell, wiring sparks, etc.). In the case of long interruptions in water

heater operation, water supply failures, EWH shall be disabled and cold water inlet

valve shall be shut off.

6. INSTALLATION AND CONNECTION

All installation, plumbing and electrical works shall be performed by qualified person-

nel.

7. ARRANGEMENT AND INSTALLATION

All installation, plumbing and electrical works shall be performed by qualified per-

sonnel.

EWH installation shall be performed in accordance with marking on the housing.

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 choosing the place of installation it should be taken into account the total

weight of EWH filled with water. Walls and floor with low carrying capacity should be

strengthened accordingly. When drilling (making) holes in the wall consider cables,

ducts and pipes in the wall.

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.

The manufacturer bears no liability for EWH falling associated with improper in-

stallation of anchors and their selection.

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 un-

protected 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 in order to perform maintenance

and warranty service (mezzanine floors, niches, ceiling voids, etc.), installation and dis-

mantling 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.

8. CONNECTION TO WATER MAINS

Cold water shall be supplied to EWH using pre-filter with water treatment level not

less than 200 µm.

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 ma-

terial (flax, FUM tape, etc.).

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 flex-

ible wiring. It is recommended to supply water to EWH through filter installed on the

cold water main (not included in the scope of supply).

Do not use used flexible feed pipes. Do not operate the EWH without

safety valve or with valve made by other manufacturers.

After connecting EWH make sure that cold water shut-off valve is open and hot

water shut-off valve (Fig. 1, p. 8) is closed. Open cold water tap in EWH (Fig. 1, p. 11),

hot water outlet valve (Fig. 1, p. 12) and hot water tap on mixer to ensure outflow of air

from the EWH. When the final EWH filling, water will continuously flow out of mixer

tap. When connecting EWH in places not provided with water supply it is permitted to

supply water in EWH from auxiliary tank using pumping station, or from reservoir

placed at a height of not less than 5 meters over the top of EWH.

Note: for ease of maintenance during EWH operation it is recommended to install

drain valve (Fig. 1, p. 4) in accordance with Fig. 1 (for models not equipped with drain-

age pipe (not in the scope of EWH supply)).

If the water pressure exceeds 0.75 MPa, at EWH cold water inlet, before the safety

valve (in the direction of water flow), the appropriate pressure reducing valve (not sup-

plied with the EWH) shall be installed to reduce water pressure to standard.

9. CONNECTION TO POWER SUPPLY

Prior to the water heater connection to electrical network, make sure its parameters

complies with the technical specifications of the water heater.

ATTENTION! Prior to power activation make sure EWH is filled with water!

Water heater shall be earthed to ensure safe operation. EWH is equipped with the

stationary power cable (option) with Europlug (option). Power outlet shall have an earth

terminal with the connected earthing wire and located in the area protected from mois-

ture, or comply with the requirements not less than 1РХ4.

10. OPERATION

The EWH is switched on/off by turning the indicator line on the control knob lo-

cated on the protective cover of the water heater (Fig. 1, p. 16) to the “OFF” zone. The

water temperature in the inner tank is adjusted using the control knob (Fig. 1, p. 16) in

the range of values from "OFF" (minimum values) to "HIGH" (maximum values). The

control indicator lamp displays the operating mode of the EWH - it glows when the

water is heated and goes out when the set temperature is reached.

11. TECHNICAL MAINTENANCE

When performing maintenance scale on THE is checked. At the same time residue

that may accumulate in the bottom of the EWH is removed. If there is scale on THE, it

can be removed by using scale removing means or mechanically. It is recommended to

hold the first technical maintenance after a year from the time of connection by experts

of a specialized organization and depending on intensity of scale and residue to deter-

mine intervals of follow-up maintenance. This action will extend the maximum EWH

service life.

ATTENTION: accumulation of scale on TEH may cause its damage .

Note: Damages to THE 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.
