Please, read the present manual before starting to use the water heater and pay attention to
the “ATTENTION!” items
The present manual is made for a water heater's model ER of from 50 to 150 liters volume and model

S of
from 30 to 80 liters volume. A full name of the model of the heater is indicated on an identification plate
located in a frame body of the heater.

Purpose
An electric water heater (hereinafter referred to the EWH) is designed to provide with hot water household
and industrial users equipped with a cold water supply line with the required parameters.
The heater shall be used in closed heated rooms and not designed for operation in continuously flowing
mode.
Main Technical Specifications
The manufacturer reserves the right to introduce changes into water heater design and characteristics
without prior notice.
Operation
Internal reservoir has a special surface made of bioglass-porcelain material that safely protects an internal
surface from electrochemical corrosion.
On a removable flange are assembled: an electric heating bundle (EHB) (
7
), a thermostat (
8
) and a
magnesium anode (
9
). The EHB is made for water heating and the thermostat provides a heating
temperature regulation up to +74°
С
(±5°
С
). The magnesium anode is designed to counteract an effect of
electrochemical corrosion to the internal reservoir.
The regulation is made using a handle of a thermostat controller (
10
) located onto a protective cover of the
heater. The thermostat also has a thermoswitch – a protection heat device that cuts off the EHB from the
power network if a water temperature exceeds +93°
С
(±5°
С
).
In the course of operation the heater case
body can be heated. It is not a breakage when the heater's thermal protection is activated. To make the
EN
heater back to operation mode is made by pushing a stock of a thermoresponsive switch located under the
heater's cover (
Fig. 3
).
Onto a protective cover of the device there are two control lamps (
11
): a control lamp of a red color is lighted
up constantly if the heater is connected to a power supply network; a control lamp of an yellow color shows
a heater's operation mode; it is lighted on when water is heated and switched off when the set-up
temperature is reached. In an electrical cable of the heater (optional) there is a protection tripping device
(PTD) provided the heater's cut off from the power network in case of leakage current occurrence on
grounded elements of the device.
Installation and connection
All assembly, plumbing and electrical installation works shall be performed by skilled staff.
Location and installation
Installation of an electric water heater (EWH) shall be made in accordance with the marking specified onto
a body frame and the following table:

It is recommended to install the electric water heater as the closest as possible to a place of use of hot
water in order to reduce a waste of heat in pipes. The heater shall be hung on anchors hooks (not included
in a supply set) fixed to a wall. For mounting it is recommended to use anchors (hooks, studs or bolts) with
diameter of not less than 8 mm. Depending on a model you will need 2 or 4 anchors. A type of these
anchoring elements shall be selected in accordance with a wall material.
Mounting of hooks in a wall shall prevent a self-movement of the heater's brackets. When selecting a place
of installation total weight of the EWH filled with water shall be taken into account. A wall and a floor that
have poor loading capacity shall be strengthened. To maintain the heater a distance from a protection
cover to the closest surface towards an axis of a removable flange should be not less than 0.5 meter.
To avoid damage of a consumer's belongings and (or) a property of third parties in case of breakage of a
hot-water supply system the assembling of the heater shall be made in rooms that have a floor
waterproofing and canalization draining. It is prohibited to place under the heater the things subject to
effect of water. When installing the electric water heater in unprotected facilities it is required to install
under it a protective tray (not included in a supply set) with canalization draining.
Shall the heater be installed in places that are difficult to approach to make maintenance operations and
warranty services (ceiling shelves, niches, ceiling spaces) assembly and dismantling works are made by a
consumer himself or at his expense.
Connection to water supply
It is necessary to pump cold water in EWH using prime water filter with the degree of
purification not less than 200 microns.
Install the safety valve (
17
) on cold water input (
21
) - the pipe nipple with the blue ring, on 3.5 - 4 turns,
having provided tightness of connection with any sealing material (flax, PTFE tape, etc.).
The safety valve carries out functions of the non-return stop valve, interfering water backflow from water
heater to water supply system in the cases when the pressure decreases in the last one, and in the cases
when the pressure increases in a tank at strong water heating, and also carries out the function of the
protective valve, dumping excessive pressure in a tank at strong water heating. When water heater is
