Inspection and care of the water
heater
The heater is positioned in the same
section of the appliance as the rotor. It
is easy to access for installation of hot
water pipes.
When starting, the battery should be
bled using the air nipple on the collec-
tor to prevent air bubbles disturbing the
water flow. See figure below (A).
Regulating the heater
The power requirements for the heater
are adjusted according to the extract
air temperature, as set on the control
panel. The temperature is indicated
using a sensor in the extract air.
Service and maintenance
The heater does not normally require
any service or maintenance. Check the
supply air side a couple of times a year
and clean if necessary.
Brush or vacuum the radiator. Take
great care when in contact with the
surface of the radiator, which must not
be deformed.
