Electric instant water heater
EN
CLEANING
Operation of the water heater may result in scaling of the shower/tap nozzle
openings. This reduces efficiency of heating, deteriorates water spraying, and
increases water pressure in the heating flask.
For prevention of such phenomena, periodically clean the nozzle using
household chemical agents and soft brushes. Do not use abrasive cleaning
substances and inappropriate chemical agents.
Prior to cleaning the outer surfaces, disconnect the water heater from the
electrical mains and allow it to fully cool down. Clean the outer surface of the
appliance housing with a slightly moistened soft cloth and then wipe it dry. Do
not use abrasive cleansers for cleaning.
If water flow rate from the water heater decreases, clean the coarse filter
(rubber gasket and strainer) installed at the cold water inlet of the water
heater. For that, disconnect the appliance from the electrical mains and
allow it to fully cool down. Then, shut off cold water feeding, unscrew the cold
water supply pipe from the water heater, remove the rubber gasket with the
strainer, and flush it under a jet of flowing water. Restore the inlet connection
in the reverse sequence.
