3. WHEN INSTALLING AND OPERATING THE EWH, IT SHALL BE FORBIDDEN TO:
connect the power supply if the EWH is not filled with water;
џ
remove the protective cover when the power is on;
џ
use the EWH without grounding or use water pipes as grounding;
џ
plug the EWH in the water supply system with a pressure of more than 0,6 MPa. If the
џ
pressure in the water supply system exceeds 0,6 MPa or is not stable and periodically
exceeds 0,6 MPa, it is necessary to install a suitable reducing valve (not included in the EWH
supply package) at the inlet of cold water in the EWH, in front of the relief valve (in the
direction of water flow) in order to reduce the pressure of cold water until it becomes normal.
It shall be forbidden to install a pressure control valve between the EWH and the relief valve;
connect the EWH to the water supply line without a relief valve;
џ
drain water from the EWH when the power is on;
џ
use spare parts not recommended by the manufacturer;
џ
use water from the EWH for cooking;
џ
use water containing mechanical impurities (sand, small stones) that can lead to the
џ
malfunction of the EWH and relief valve;
switch on and use the EWH with closed input and output valves (branch pipes).
џ
change the design and mounting dimensions of EWH brackets;
џ
4.
Freezing of water in the device is unacceptable, as this leads to its failure, which is not a warranty
case.
5.
The EWH is not intended for use by persons with reduced physical, tactile, or mental capabilities, or
by persons who cannot use the EWH, except when it is monitored or in accordance with instructions
from persons responsible for EWH safety. Children can use the EWH only under the supervision of
persons who know how to safely operate it. One shall always bear in mind that there is a risk of
scalding with water and electric shock.
6.
If the buyer does not comply with Clauses 1 – 4 of this section, the manufacturer's warranty shall be
canceled.
7.
It shall be forbidden to leave the EWH switched on in the power supply network in the absence of
supervision for more than 1 day.
Description and principle of operation
The EWH consists of casing, a heating element, a thermostat, a relief valve, and a protective cover
with control elements.
The EWH casing consists of a steel tank thermally insulated with environmentally friendly
polyurethane foam and two threaded pipes: cold water inlet pipe (with a blue ring) and hot water outlet
pipe (with a red ring). The inner tank has a special glass-porcelain coating, which reliably protects the
inner surface from chemical corrosion.

Information concerning the application area and the method of determining the manufacture
date:
The release date of the product is encoded in a unique serial number located on the identification
plate (sticker) placed at the bottom of the product. The serial number of the product consists of
thirteen digits. The third and fourth digit of the serial number represent the year of issue, the fifth and
sixth – the month of release, the seventh and eighth
–
the day of the EWH release date.
Indication of security measures
1. All installation, plumbing, and electrical work shall be carried out by qualified personnel
only!
2.
Electrical safety and anti-corrosion protection of the EWH are only guaranteed upon availability of
efficient grounding performed in accordance with the current Electrical Installation Regulations (EIR).
