Troubleshooting
The units are manufactured
using state-of-the-art production
methods and tested several times
to verify their correct function.
However, if a functional fault
should occur, the unit should first
be checked in accordance with the
following list.
The unit does not start:
■
Check for any timer
programming
Indicator light [

Check the power supply and
the power fuse provided by the
customer

Filter cleaning
To prevent damage to the unit, it is
equipped with an intake grill with
integrated air filter.
In order to prevent power losses
or unit faults, the intake grill
with filter must be inspected as
required, but every 2 weeks at the
latest, and cleaned if necessary.
1. Use the control panel ([
] key)
to switch the unit off.
2. Remove the power plug from
the mains socket.
3. Remove the condensate
container [K].
4. Pull the filter [F] that is behind
the intake grill downwards and
out.
The units are not permitted to
be operated without the intake
grill and air filter fitted!
