Action
1
- Frost forms on the Internal Unit heat
exchanger.
1.A
- Frost only at the bottom of the heat
exchanger: gas leak.
1.B
- Frost covers the entire heat ex-
changer: the air fi lter is clogged.
The room temperature is low
(
<
20°C).
· Find the leak and recharge.
· Clean the air fi lter.
Unplug the appliance and switch off
the dedicated switch before cleaning
(risk of electrocution).
· Check the room temp.
2

leak.
· Find the leak.
· Replace the heat exchanger.
3
- The compressor runs but there is
little cooling.
3.A
- The External Unit heat exchanger
is clogged or covered: you do not
have a good heat exchange.

exchanger are bent.
· Clean the External Unit heat exchang-
er.
· Straighten the fl aps on the external
heat exchanger.
4
