OPERATING INSTRUCTIONS
The air sucked by the fan enters from the grill and
passes through the filter, then it is cooled/dehumidified
or heated through the heat exchanger.
The direction of the air outlet is motorized up and down
by flaps, and manually moved right and left by the vertical
deflectors, for some models, the vertical deflectors could be
controlled by motor as well.
“SWING” CONTROL OF THE AIR FLOW
1.Press the button to activate the FLAP .
2. Press the button again when the “FLAP” is at your desired
airflow direction. The swing motion will be deactivated.

Refrigerant piping connection
The piping can be run in the 3 directions indicated by
numbers in the picture . When the piping is run in
direction 1or3, cut a notch along the groove on the side
of the indoor unit with a cutter.
Run the piping in the direction of the wall hole and bind
the copper pipes , the drain pipe and the power cables
together with the tape with the drain pipe at the bottom,
so that water can flow freely.
Do not remove the cap from the pipe until connecting
it, to avoid dampness or dirt from entering.
If the pipe is bent or pulled too often , it will become
stiff . Do not bend the pipe more than three times at
one point.
When extending the rolled pipe, straighten the pipe by
unwinding it gently as shown in the picture.
Connections to the indoor unit
1. Remove the indoor unit pipe cap (check that there is
no debris inside).
2. Insert the fare nut and create a flange at the extreme
end of the connection pipe.
3. Tighten the connections by using two wrenches
working in opposite directions.

Indoor unit condensed water drainage
The indoor unit condensed water drainage is fundamental for the success of the installation.
1. Place the drain hose below the piping, taking care not
to create siphons.
2. The drain hose must slant downwards to aid drainage.
3. Do not bend the drain hose or leave it protruding or
twisted and do not put the end of it in water . If an
extension is connected to the drain hose , ensure that
it is lagged when it passes into the indoor unit.
4. If the piping is installed to the right, the pipes, power
cable and drain hose must be lagged and secured onto
the rear of the unit with a pipe connection.
1) Insert the pipe connection into the relative slot.
2) Press to join the pipe connection to the base.

INSTALLATION MANUAL---Installation of the outdoor unit
ELECTRICAL CONNECTIONS
1. Remove the handle on the right side plate of outdoor unit.
2. Connect the power connection cord to the terminal board.
Wiring should fit that of indoor unit.
3. Fix the power connection cord with wire clamp.
4. Confirm if the wire has been fixed properly.
5. An efficient earth connection must be ensured.
6. Recover the handle.
CONNECTING THE PIPES
Screw the flare nuts to the outdoor unit coupling with
the same tightening procedures described for the indoor
unit.
To avoid leakage, pay attention to the following points:
1. Tighten the flare nuts using two wrenches. Pay atten tion not to damage the pipes.
2. If the tightening torque is not sufficient , there will
probably be some leakage. With excessive tightening
torque there will also be some leakage, as the flange
could be damaged.
3. The surest system consists in tightening the connecti on by using a fix wrench and a torque wrench:in this
case use the table on page 28.
