7. MAINTENANCE
During use of the water heater, scale may appear in nozzle openings of the
shower or kitchen spout. This reduces efficiency of heating, deteriorated
water spraying, and increases water pressure in the heating vessel.
For prevention of such phenomena, it is necessary to periodically clean the
nozzle using household chemical agents and soft brushes. Do not use
abrasive cleaning substances and inappropriate chemical agents.
a) Outer care:
- Switch off the appliance and allow it to fully cool down.
- Clean the outer surface of the appliance enclosure using a slightly moist-
ened soft cloth and then wipe it dry. Do not use abrasive cleaning sub-
stances.
b) Filter cleaning:
If water flow rate from the heater decreases, it is necessary to clean the
coarse filter installed at the cold water inlet to the water heater. Use the
following procedure:
- Switch off the appliance and allow it to fully cool down.
- Shut off cold water feeding.
- Unscrew the cold water feed hose from the water heater, remove the
coarse strainer and flush it under a jet of flowing water.
- Restore the inlet connections in the reverse sequence.
