Electrical instant water heater

Water supply network connection

The water heater is connected to the cold water supply network with operating pressure from

0.1 MPa to 0.7 MPa. If water pressure in the water supply network exceeds 0.75 MPa, install a

reduction valve (pressure reducer) in the feed system so that operating pressure does not exceed

0.75 MPa.

If water hardness in the water supply main exceeds 450 mg/l (CaCO3), we recommend you to use

a separate water lter upstream of the water heater inlet to extend service life of the heating

element.

For connection to the water supply network, the water heater has inlet and outlet connectors,

which are marked with indication labels and provided with male thread 12 mm in diameter

(G1/2”).

Install the combined check valve / pressure safety valve provided in the package onto the cold

water inlet connection marked with blue color. Connect a drain tube to the pressure relief port of

the pressure safety valve for water drainage to the sewers (possible upon heating).

CAUTION!

Never operate the water heater without the installed check

valve / pressure safety valve.

To facilitate maintenance of the water heater, we recommend you to install a drain valve and a

tee between the cold water inlet connection and pressure safety valve. This tee will help you to

faster drain water from the water heater. For your convenience, we recommend you to connect

a water drain hose to the shuto valve of the tee. This hose will allow you to route water drained

from the water heater to the sewers or another selected destination. Connect the desired

quantity of consumption points to the hot water outlet connection marked with red color. Open

the cold water feed valve and one of the demountable valves in order to pass water ow through

the water heater and make sure that it is operable. Aer the tank has been lled as indicated

by water owing from the demountable valve, close it, check tightness of all connections, and

retighten them as necessary.

Electrical mains connection

The power cord of the water heater has a plug with a grounding contact. The water heater shall

be used with the properly grounded mains socket. If the socket planned for use is not properly

grounded or protected with a time-delay fuse / circuit breaker, please contact a qualied electri-

cian for replacement of the socket.
