XTR H1, WHE 5.5 XTR H1
1. Water heater shall be directly connected to cold water supply line with
working pressure from 0.15 to 0.6 MPa. If water pressure in water supply line
exceeds 0.6 MPa, a pressure reducing valve shall be included to the feeding
system to assure that working pressure does not exceed 0.6 MPa.
2. Water heater has inlet and outlet nozzles for connection to water main, the
nozzles are marked with indication labels; the diameter of external thread is
10 mm (G3/8»). For connection to 12 mm (G1/2”) pipes special adapters*
shall be used. (* - not included into the scope of supply).
3. To avoid water leakages use rubber sealing gaskets when connecting all
nozzles.
4. A tap cutting off cold water supply shall be installed upstream its inlet to
water heater. It is prohibited to install the cut-off tap at hot water outlet from
water heater (Fig.14).
5. After water heater installation and before power supplying, the system
shall be flushed with water to remove any impurities or free particles inside
water heater. Otherwise, water heater operability may be affected.
6. It is RECOMMENDED to use a separate water filter at cold water inlet
to increase the heating element lifetime if water hardness exceeds 450mg/l
(СаСОз).
NOTE:
Water heater installation at the place of its operation
and electric power connections shall be performed
by the specialized organization, a representative
of the manufacturer’s maintenance service or
experts licensed for execution of electric equipment
assembling with safety regulations observed.

manual, water heater is not subject to warranty
servicing, and the manufacturer cannot be held liable.
IMPORTANT!
If water heater is used at specially complicated
(obsolete) water supply networks with high amount of
suspended particulate matter and impurities contained
in water flowing through the mains, purifying filters shall
be used on a COMPULSORY basis. Please, follow this
recommendation, otherwise, the non-execution of this
provision may influence the lifetime of the device and
warranty servicing conditions (up to refusal to execute
warranty liabilities by the device manufacturer and its
maintenance services).
7. Make sure that water heater is operable, let water flow pass through it.
Check the tightness of all connections and, if needed, tighten all retaining nuts
and screws.
NOTE:
Prior to water heater installation, flush water supply
pipes with flowing water.
