2. Please note
Excessive air pressure can
result in the deformation of
the aluminium fins of the
heat exchanger.
Only point the compressed
air gun at the heat exchan-
ger from the front and at an
adequate distance. Air
forced at the aluminium fins
from the side will result in
their deformation.
Blow out the heat exchanger from
the inside out with compressed air.
3. Check the aluminium fins of the
heat exchanger for deformation
and scratches; if required repair
with a suitable tool.
4. Close the casing of the external
unit.
Check the operating instruc-
tions for information regarding
the removal and installation of
the air filter.
Clean the filter with a vacuum cleaner
or fresh water.
