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.
2.6.1
Cleaning the air filter
OPERATION TO BE PERFORMED WHEN THE MACHINE IS SWITCHED OFF AND THE POWER SUPPLY IS DISCONNECTED.
To ensure effective internal air filtration and satisfactory operation of your air conditioner, the air filter has to be cleaned periodically.
The need to perform this important maintenance operation is signalled after a long period of use through the lighting up of two LEDs
on the warning panel.
The air filter is at the top of the unit.
Removing the filter:
-
turn off the unit and wait until the suction flap has closed
-
manually lift the air suction flap (fig. 25)
-
lift the front part of the filter (fig. 25 ref. A)
-
pull slightly to remove the edge from the upper grid (fig. 25 ref. B)
-
remove the two supplementary filters (green purifying filter ref. B and black active carbon filter ref. C) from the filter unit (fig.
27 ref. A)
-
wash and dry all the filters
-
fit the active carbon filter (black) (fig. 26 ref. C) on the filter unit (fig. 26 ref. A) and lock it to the specific tongues (fig. 26 ref.
D)
-
fit the purifying filter (green) (fig. 26 ref. B) on the first pin that is on the filter unit (fig. 26 ref. E), pull it slightly and lock it on
the other two pins (fig. 26 ref. F)
-
refit the filter unit by inserting the rear edge (fig. 27 ref. B) into the grid (fig. 27 ref. A)
-
lower the front edge (fig. 27 ref. C) on the machine
-
manually close the suction flap.
Finally, use an object with a pointed tip to press the micro-button, located on the warning panel, for a second (fig. 22 ref. H).
WARNING: in order to avoid damaging the unit, the manually open and close the air suction flap very carefully,
avoiding abrupt movements that could damage the plastic and mechanical parts.
WARNING: after having cleaned the filters, the air suction flap might stop in a wrong position on turning on the unit again. In this
case:
-
turn off the unit
-
manually move the suction flap to closed position
-
cut off power supply (disconnect the power cable)
-
wait about 30 seconds
-
plug in the power cable
-
turn on the unit.
