adjustment of the water heater, when necessary. After you have selected
the place for installation of the water heater, mark points for mounting
screw holes. Drill two holes to appropriate depth in the wall using a drill with
suitable size for the dowel pins and screws provided in the water heater
package. Insert the dowel pins into the wall holes and turn in the mounting
screws. Do not turn in the screws fully. There shall be a gap between the
screw heads and wall necessary to hang up and secure the water heater.
Hang up the water heater onto the screws and check security of mounting.
The appliance shall be installed on the wall strictly horizontally with its
connections downward. For more secure mounting, you can use the through
hole in the lower part of the rear panel (refer to “Overall and installation
dimensions”) to turn in an additional screw through it to the wall.

Water supply network connection
The water heater is directly connected to the cold water supply network with op-
erating pressure from 0.07 MPa to 0.6 MPa. If water pressure in the water supply
network exceeds 0.6 MPa, install a reduction valve (pressure reducer) in the feed
system so that operating pressure does not exceed 0.6 MPa. Prior to connecting
the water heater, flush the cold water supply pipe with flowing water.
If water hardness in the water supply main exceeds 450 mg/l (CaCOз), we
recommend you to use a separate water filter upstream of the water heater
inlet to extend service life of the heating element.
Connect the cold water supply pipe to the cold water inlet marked with blue
color. Install the rubber gasket and strainer provided in the package between
the pipe and connection. The connection has male thread 12 mm in diameter
(G1/2”). Connect the accessories provided in the package to the heated water
outlet marked with red color (refer to “Accessories” and version of your water
heater). The cold water feed isolation valve shall be installed upstream of the
water heater inlet. Never install an isolation valve at the heated water outlet
of the water heater. Water outlet should be always open. Pass water flow
through the water heater to make sure that it is operable. Check tightness of
all connections and retighten them as necessary.
