CHAP. 4.1 TROUBLESHOOTING
In case of malfunctions of the air-conditioner, check the items in the table below
If, after making the suggested check the problem is not solved, contact you authorized service centre.
- The air conditioner does not switch on. This may be due to:
- lack of power;
what to do:
- Make sure power is being supplied (by switching on a light in the house, for example).
- Make sure the main circuit breaker is closed and the fuse is not burnt out (replace the fuse if necessary.
If instead of a circuit breaker you have installed a cutoff switch, make sure it has not been tripped (reset it if necessary).
If the problem persists, contact our Service Department and do not try to start the air conditioner.
- The batteries in the remote control are dead.
If the batteries are dead you will notice the absence of indications on the display and the failure of the air conditioner to beep
when you try to send it a command. In this case, replace the batteries.
- The device no longer cools satisfactorily, this could be due to:
- The temperature set on the remote control being too high or too low (for models with heat pump);
what to do:
- check and, if necessary, correct the temperature setting on the remote control.
- The air filter is clogged before the alarm indicator lights up.
what to do:
- check and clean if necessary..
- Something is obstructing the airflow to the inside or to the outside;
what to do:
- remove anything that could obstruct airflow.
- There has been an increase in the heating or cooling load (for example a door or window has been left open or a device
that dissipates a large amount of heat has been installed in the room);
what to do:
- make sure the doors and windows are closed; if a heat source has been installed in the room that raises the temperature
excessively and for which the air conditioner is unable to compensate, the only solution is to install another air conditioner
or replace the existing one with a more powerful model.
- The air conditioner stops and the second and third led from the left on the control panel (orange, green and red lights)
start flashing;
If there should be a malfunction in the condensation water drain system, the air conditioner stops working and signals,
with flashing orange, green and red lights (the second and third leds from the left), the alarm status.
To enable the air conditioner to work temporarily until the service personnel arrives, you can drain the water out by following
these simple instructions:
- Grasp the rubber cap on the bottom centre of the air conditioner behind the edge of the frame facing the wall between
your thumb and forefinger.
- Pull the rubber tube closed by the cap out by a few centimetres.
- Remove the cap after placing a bucket or other container underneath it (at least five litter capacity) to collect the water.
- After eliminating the malfunction the service personnel will take care of closing the evacuation tube.
IMPORTANT: If you are unable to classify the problem as one of those described above, you should immediately
get in touch with our Service Department without attempting to make any repairs yourself.
