(not in the scope of supply), 5 – safety valve, 6 – drainage (not in the scope of
supply), 7 – feed pipe, 8 – shut off valve when EWH operation, 9 – cold water main, 10
– hot water main, 11 –cold water shut-off valve, 12 – hot water shut-off valve, 13 –
protective cover, 14 –exhaust pipe of the safety valve, 15 – handle for opening pressure
relief valve, 16 – control panel, 17 – discharge pipe.
After connecting EWH make sure that cold water shut-off valve is open and hot
water shut-off valve (8) is closed. Open cold water tap in EWH (11), hot water outlet
valve (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 0.8 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.
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.
