that has the best characteristics of insulation. EWH has two threaded pipes: for cold water input (fig. 1,

p. 3) with the blue ring and hot water exhaust (fig. 1, p. 2), with a red ring.

The control panel is located on the protective cover (fig. 1, p. 19).

Tubular electric heater (TEH), thermostat and thermal switch sensor are mounted on the removable

flange. TEH is used to heat water and is controlled by the thermostat that has a smooth temperature

regulation up to +74° c (± 5° c). The thermostat automatically maintains water temperature at the level

set by the user. Temperature adjustment knob is located on the protective cover (fig. 1, p. 20).

All installation, plumbing and electrical works must be performed by qualified personnel.

Arrangement and installation

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. EWH is suspended by brackets on hook anchors (supplied) fixed in the wall.

Hooks mounting on the wall should exclude spontaneous movement of EWH brackets along them.

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. To perform

aintenance and servicing of EWH the distance from the protective cover to the nearest surface in the

direction of removable flange axis shall be at least 0.5 m.

by the user on his own or for his own account.

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 (5) at the cold water inlet (3) tube with the blue ring, with 3.5-4 revolution,

ensuring junction tightness with any sealing material (flax, FUM tape, etc.).

Safety valve is back-flow valve preventing ingress of water from the water heater to water main in case of

pressure drop in the latter and in case of pressure increase in the tank when water is heating up, as well

as safety valve, relieving excess pressure in tank when water is heating up. During water heater

Water drainage from the safety valve exhaust pipe into sewage shall be ensured providing with

corresponding drainage when installing EWH (8).

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 (6) is intended to open the valve (5). It is necessary to control when operating water heater this

handle to be in position closing water draining from the tank.

order to avoid damage to pipe threads.

shut-off valve in EWH (14) is closed. Open the EWH cold water tap (10), hot water outlet tap (11) and hot

water mixer faucet to allow outflow of air from EWH. When complete filling of EWH water will constantly

flow from tap faucet. Close the hot water tap on faucet mixer, check the flange for leaks and, if necessary,

tighten the bolts.

When connecting EWH in places not provided with water mains it is allowed to supply water to EWH

from auxiliary tank using pumping station, or from the tank placed at a height of not less than 5 meters

from the top of EWH.

Connection to power supply

Before connecting of water heater to power supply, make sure that its settings correspond to

specifications of the heater.

ATTENTION! Before switching on power supply, make sure that EWH is filled with water!

Control panel has power selection keys (Fig. 1, p.17, 18) with integrated indicator lamps.
