The interior fan will always continue rotating even if the desired temperature has been
reached and the condenser unit has stopped.
extremes of outside temperature this potential may be reduced.
Expansion/
Contraction
During Heating or Cooling, some plastic pieces could expand or contract due to the
variation on temperature. This phenomenon is normal and disappears after some
instants.
Problem Description Possible cause Solution
The Air Con unit doesn’t work at
all.
The Compressor works but very
frequent
Incorrect Heat/ Cooling/ Humidity
Noises inside the unit can be
heard.
1. No Power to the unit
2. Voltage too low

Something in front of the external
unit
1. Air filter dirty or obstructed.
2. Presence of source of heat or too
many people in the room.
3. Doors or Windows open.

plastic pieces can expand and
contract due to the abrupt variation
in temperature.
1. Restablish power
2. Contact Electrician
3. Switch On
Remove the obstacle
1. Clean the filter to improve
circulation.
2. Eliminate the source of
heat
3. Close them to impede flow
of heat/cold
This is normal and should
disappear in a short while.
