Disposal

Upon expiration of service life, the water heater shall be disposed. For more details regarding 
disposal of the water heater, please contact a representative of the local authorities.

Service life is around 10 years. The notion of the service life of the device is not equal to the 
warranty period.

INSTALLATION

                      CAUTION! 

                                           Refer to «Water heater safe operation and installation rules».

During installation of the water heater, rigorously observe the laws, regulations, directives, and 

standards (safety requirements, disposal rules/procedure, electrical safety rules, etc.) effective in 

your country, as well as directives of local electrical energy/water suppliers.

Mounting

During selection of a location for the water heater, it is necessary to ensure free access to it 
on the basis of not less than 0.3 m from above, from below, and sideways. This will ensure the 

maximum comfort for maintenance and 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 dimen-
sions”) 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 operating 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 (CaCO3), 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 con
