WATERMASTER I Series. Water Heater Models: WHE 3.5 XTR H1, WHE 4.5 

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 wa-
ter 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 sys-

tem shall be flushed with water to remove any impurities or free 
particles inside water heater. Otherwise

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 (

).

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
