The water temperature in the inner tank is adjusted by means of the thermostat handle (10) located on
the protective cover of the water heater. The thermostat also contains a thermal switch –the device
EN
protects the EWH from overheating, which disconnects the heater from the power supply network
when the water temperature exceeds + 93°С (±5°С). EWH may heat up during operation. The
activation of the thermal protection of the water heater is not its malfunction. To return the water heater
to the working state, press the thermoswitch rod located under the protective cover of the EWH
(Fig. 2).
The relief valve functions as a non-return valve by preventing the water from entering the water pipe in
case of pressure drop in the latter and in case of increase in the pressure in the tank with strong water
heating and as a relief valve by relieving the overpressure in the tank when the water is heated up
strongly.
Depending on the EWH model, the protective cover (4) has one or two control lamps indicating the
instrument operation or power selection keys.
In models with a single control lamp, the lamp indicates the EWH operation mode – it is lit up when the
water is heated and goes out when the set temperature has been reached.
In models with two control lamps, the «Heating» Lamp indicates the EWH operation mode – it is lit up
when the water is heated and goes out when the set temperature has been reached. The «Power»
Lamp is lit up constantly – it indicates the device connection to the power supply network.
For models with power selection keys, the indicator of the EWH operation mode is used for the lamps
intended for highlighting power selection keys – they are lit up when the water is heated and go out
when the set temperature has been reached.

Placement and Installation

It is advisable to install the EWH as close as possible to the place of use of hot water in order to reduce
heat losses in the pipes.
When selecting the installation site, the total weight of the EWH filled with water shall be taken into
account. The wall and the floor with a weak load-carrying capacity shall be strengthened, respec-
tively. When drilling (making) holes in the wall, it is necessary to take into account the cables,
channels, and pipes passing through it. The EWH is suspended using the casing brackets on the
anchor hooks fixed in the wall.
The manufacturer shall not bear responsibility for the EWH fall due to its incorrect installation.
The installation of hooks in the wall shall prevent the spontaneous movement of the EWH brackets
over them. For the purposes of EWH maintenance, the distance from the protective cover to the
nearest surface in the direction of the removable flange axis shall be at least 0.5 meters.
In order to avoid causing harm to the property of the customer and (or) third parties in case of faulty hot
water supply system, it is necessary to install the EWH in premises that are equipped with waterproof-
ing floors and drainage to the sewage system, and under no circumstances should you place non-
