8.3 Cleaning the Air System

Evaporator, ventil ator and condensate outflow should be cleaned
of contamination (leaves, twigs, etc.) before each new heating
period.
ATTENTION!
Before opening the device, ensure that all circuits are isolated from the
power supply.
To prevent the evaporator and the condensate tray from being
damaged, do not use hard or sharp objects for cleaning.
ATTENTION!
The refrigerating circuit may not be damaged in any way.
Inflammable re frigerant could leak out if th e refrigerating circuit is
damaged. Ignition sources and open flames must be avoided
when carrying out any work on the device.
Under extreme weather conditions (e.g. snow drifts), ice may
form on the air i ntake and exhaust air outl et grids. If this happen s,
the ice must be removed in the vicinity of the air intake and ex-
haust air outlet grids to ensure that the minimum air flow rate is
maintained.
