CHECKS WITHOUT THE USE OF TOOLS OR INSTRUMENTS
Operation in Cooling mode - Visual checks on the Internal Unit
Problem Check 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 - No condensation forms. 2.A - If the Internal Unit heat exchanger
remains dry and the electricity con-
sumption is much lower than the
rated value, then there is a 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.
3.B - The fl aps on the External Unit heat
exchanger are bent.
· Clean the External Unit heat exchanger.
· Straighten the fl aps on the external
heat exchanger.
4 - The air temperature is low, but there
is little cooling.
4.A - The Internal Unit fi lter is clogged.
4.B - The air recirculates in the Internal
Unit.
4.C - The machine has not been sized
correctly or is overloaded e.g.: heat
sources, overcrowding,...).
· Clean the fi lter.
· Encourage the free circulation of air.
· Replace the appliance or remove the
overload.
5 - The compressor does not start. 5.A - The compressor is very hot: heat
protection.
· Wait for the temperature to drop.
6 - The appliance comes to a stop after a
few minutes of operation.
6.A - The internal unit fan is broken. · Replace the motor.
· Only use original spare parts.

2 - The remote control does not work or
only works from a short distance.
2.A - Check whether the batteries are
low.
2.B - Check whether there are any ob-
stacles (curtains or ornaments) be-
tween the remote control and the
air conditioning unit.
2.C - Check whether the distance be-
tween the remote control and the
unit is too far.
· Replace the batteries.
· Remove all obstacles.
· Move closer to the air conditioning unit.
