Electrical instant water heater
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
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.) eective in
your country, as well as directives of local electrical energy/water suppliers.
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. Aer
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, ush the cold water supply pipe with
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
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
