Checking the free rotation of the external fan
Danger
Unintentional starting of the fan
can lead to severe injuries.
Isolate the unit from the power
supply, check that it is no
longer 'live' and safeguard
against unauthorised recon-
nection.
1.
Remove the front grille from the
external unit.
2.
Turn the fan by hand.
Cleaning the heat exchanger of the external unit
1.
Open the casing of the external
unit.
!
Please note
The sharp edges of the heat
exchanger can result in inju-
ries.
Avoid contact with the
exchanger.
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.
