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).

WATERMASTER II Series. Water Heater Models: WHE 5.0 XTN Z1, WHE
6.5 XTN Z1, WHE 8.0 XTN Z1.
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
12 mm (G1/2»).
3. To avoid water leakages use rubber sealing gaskets when connecting all
nozzles.
4. 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.
5. 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)
6. 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.
WATERMASTER III Series. Water Heater Models: WHE 12.0 XTL С1, WHE
18.0 XTL C1, WHE 21.0 XTL C1, WHE 24.0 XTL С1.
1. Water heater shall be directly connected to cold water supply line with
working pressure from 0.1 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 and are equipped with coupling
nuts, 12 mm (G1/2”) external thread diameter, and 2 adapters, 12 mm
(G1/2”) external thread diameter.
3. To avoid water leakages use rubber sealing gaskets when connecting all
nozzles.
4. 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.
5. 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:
Prior to water heater installation, flush water supply
pipes with flowing water.
