cluded 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 sys-
tem 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 (
)
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.
NOTE :
Prior to water heater installation , flush water supply pipes with
flowing water .
ATTENTION !
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 III Series. Water Heater Models: WHE 12.0 XTL 1, WHE 18.0
XTL C1, WHE 21.0 XTL C1, WHE 24.0 XTL 1.
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 diam-
eter, and 2 adapters, 12 mm (G1/2 ) external thread diameter.
3. To avoid water leakages use rubber sealing gaskets when connect-
ing 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.

inlet to increase the heating element lifetime if water hardness
exceeds 450 mg / l ( ).
