It is possible to terminate the function prematurely simply by switching the appliance off using the remote control.
Should the conditioner block and signal an error (as indicated in the following table), specify the LEDs that are flashing to the service
centre in order to facilitate the intervention (fig. 22).

2.5.1
Evacuating condensate water during an emergency
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 arrive, you can drain the water out by following these
simple instructions:
-
remove the lower cover (fig. 23 ref. A)
-
remove the cap (fig. 23 ref. B) after having placed a good-sized container underneath it (at least 5-liter capacity) to collect
the water (see fig. 23)
-
after having cleared the fault, the service personnel will close the evacuation pipe.

ROUTINE MAINTENANCE
The air conditioner that you have purchased has been designed to reduce routine maintenance operations to a minimum. These
operations involve solely the cleaning operations outlined below:
-
Cleaning or washing of the room air filter each time the relative red LED lights up (this can be done by the user, see user manual)
-
Cleaning of the condensing battery and cleaning of the condensate management system. These operations must be carried out
by skilled technicians on a regular basis that will depend on the place of installation and intensity of use. Depending on the quantity
of dirt, the unit can be cleaned dry (by using a battery compressor and bowl and cleaning the fins with a soft brush taking care
not to deform them) or more thoroughly using dedicated detergents.
Before you leave the site of installation you should gather up all packing material and use a damp cloth to remove any traces of
dust that may have deposited on the machine during assembly (fig. 24).
These operations, though certainly not essential, have a beneficial effect as they enhance the professional image of the installer
in the eyes of the client.
To prevent unnecessary calls by the user, before you leave the site of installation it is also a good idea to:
-
Explain the contents of the Instruction Manual to the user.
-
Show the user how to clean the filter.
