8. Service and maintenance
8.1. General maintenance
In principle, the heater is maintenance-free.
The heater casing can be cleaned with a normal, non-abrasive
household cleaning agent.
Depending on the intensity of use and the composition of the mains
water, scale deposits can build up in the heater. Please consult your
installer.
8.2. Emptying the water heater
a) Turn off power to the heater.
b) Open the hot water tap until cold water runs out.
c) Shut off the water mains stop tap or the shut-off valve for the
safety group.
d) To release pressure from the system, open the hot water tap.
e) Once the water stops flowing, shut off the tap again.

Caution!
During the next step, a small amount of water may exit the
heater's inlet hose until the water inside the heater has built up
a vacuum.
f) Disconnect the cold water pipe from the heater inlet.
g) Connect a flexible hose to the heater inlet with the other end of
the hose at the drain.
h) Open the hot water tap to allow the heater to draw in air. The
heater will then empty via the heater inlet.
