TROUBLESHOOTING
In case of faulty system operation, refer to the following table.
If, after making the suggested inspections and controls, the problem has not been remedied, contact the authorised after-sales service.
ANOMALIES
The unit does not switch on
The unit does not cool/does not heat
sufficiently anymore
- If any faults were to occur to the water condensation disposal system of the air conditioner it will come to a standstill and will signal
the malfunction using the OF alarm (see paragraph 2.5)
To enable the air conditioner to work temporarily until the service personnel arrives, you can drain the water out by following these
simple instructions:
- Disconnect the equipment from the mains
- 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.
- Connect the equipment to the mains
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.

POSSIBLE CAUSES
• Electrical power is absent
• The batteries of the remote control are
discharged
• The temperature set on the remote control is too
high or too low (in the case the unit is with heat
pump);
• The air filter is clogged before the relevant
cleaning warning light lights up
• There are obstructions to the air flow inside or
outside
• The thermorefrigerating load has increased (for
instance, a door or window have been left open,
or equipment has been installed in the room
which sinks a large quantity of heat);

REMEDIES
• Verify if there is voltage in the mains (turn on a light,
for instance).
• Make sure the master switch is closed or that a
fuse is not burned (replace, if needed). If a
thermomagnetic switch is installed instead of the
master switch, verify that the former has not tripped
(if it has tripped, it must be reset).
If the problem persists, contact the After-Sales
Service immediately, and avoid trying to make the
unit operate.
• If the batteries are discharged, the display will not
show any information, and no confirmation acoustic
signal will be heard when transmitting whatever
command to the unit. In this case replace the
batteries.
• Verify and possibly correct the temperature setting
on the remote control.
• Check it and clean it if necessary.
• Remove anything which could obstruct the air flows.
• 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.
