has been turned on, hot or warm air is not given off
immediately but after approximately 3 minutes.
If the cooling lines exceed eight metres (in one direction),
introduce 20 grams of charge into the system for every extra
metre.
Topping up is carried out in the following manner:
a) Procure a charging station with a cylinder graduated in
grams, a gauge collector with two flexibles, one of which
must be connected on the gas side of the charging
station and the other must be connected to the service
valve on the external unitis gas line connection (or in the
case of Multisplit, connected to the service valve on one
of the gas lineis connections). Should a charging station
not be available, the gauge collector may be connected
to a R410A cylinder placed on a balance. The service
valve is accessible once the cap has been removed.
b) Turn the appliance on and leave it running for a couple
of minutes.
c) Slowly open the charging stationis or cylinderis faucet
until the right quantity of R410A has entered into the
system (the quantity can be observed from the index
scale on the cylinder or from the balance).
IMPORTANT: The air conditioner must be recharged with
R410A ecological refrigerant while the refrigerant is in its
liquid state. Once charged, wait for at least 10” before
starting the compressor to allow the fluid to evaporate.
e) When the operation is finished, remove the flexible from
the service valve and close the cap firmly one more.
IMPORTANT: Avoid using more cooling liquid than is
absolutely necessary as doing so could have a negative
effect on the applianceis output. Additionally, surplus
charging can be dangerous for the applianceis functioning.

Running tests and identifying any malfunctions
The microprocessor in the appliance is programmed to carry
out a brief self-test to make sure the appliance runs correctly
by activating the various internal components.
To run the self-test proceed as follows:
-
Connect the appliance to the power supply.
-
With a pointed instrument press for at least 10 seconds
the micro pushbutton located under the hole on the left
of the display console.
-
At the start and end of the self-test procedure the
configuration status of the appliance is displayed for a
few seconds in accordance with the following diagram:
red LED (filter):
off = COLD ONLY
on = HP (with heat pump)
green LED (compressor):
off = with ambient temperature
correction
on = without ambient temp.
correction
yellow LED (timer):
off = without ambient temp.
correction
on = with ambient temperature
correction
green LED (power supply) off = stand-by in case of a
blackout
on = restart in case of a
blackout
