Install the indoor unit level on a strong wall
that is not subject to vibrations.
The inlet and outlet ports should not be obstructed: the air should be able to blow all over the
room.
Do not install the unit near a source of heat,
steam, or flammable gas..
Install the unit near an electric socket or private circuit.
Do not install the unit where it will be exposed
to direct sunlight.
Install the unit where connection between
indoor and outdoor unit is as easy as possible.
Install the unit where it is easy to drain the condensed water.
Check the machine operation regularly and
leave the necessary spaces as shown in the picture.
Install the indoor unit where the filter can be
easily accessible.

Do not install the outdoor unit near sources of heat,
steam or flammable gases.
Do not install the unit in too windy or dusty places.
Do not install the unit where people often pass.
Select a place where the air discharge and operating
sound level will not disturb the neighbours.
Avoid installing the unit where it will be exposed
to direct sunlight (otherwise use a protection, if
necessary, that should not interfere with the air
flow).
Leave the spaces as shown in the picture for the air
to circulate freely.
Install the outdoor unit in a safe and solid place.
If the outdoor unit is subject to vibration, fix rubber
gaskets onto it.

The condensed water and the ice formed in the outdoor
unit during heating operation can be drained away
through the drain pipette.
Installation: fasten the drain pipette in the 25 mm hole
placed in the lower part of the unit as shown in the picture.
Connect the condensed water hose and the pipette. Pay
attention that water is drained in a suitable place.

WALL HOOK BRACKET
Installation of the wall hook
bracket
1. By using a level, put the wall hook
bracket in a perfect square position, both
vertically and horizontally
2. Fix the bracket first with 5 screws.
3. Use several more tapping screws to secure
the bracket onto the wall with even pressure on
the screws.
4. Cut a hole in the wall for the piping and
electric connection.
N.B.
Drill a hole in the wall with the outdoor side
5-10 mm lower than the inner side, in order
to have a good drain flow.
Note: The shape and dimensions of the wall
hook bracket could be modified without
prior notice.
NOTE : Maintain the drain pipe in the lower part of the
wall hole, or leakage may occur.

The piping run towards the right
Refrigerant piping connection
The piping can be run in the 5 directions indicated by
numbers 1, 2, 3, 4, 5 in the figure. When the piping is
run in direction 1, 2, 4 or 5, 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.
Indoor unit installation
Run the bound pipe and cables through the wall hole
and mount the indoor unit onto the upper part of the
wall hook bracket securely
Arrange the pipes and cables well.
Push the lower part of the indoor unit tight against the
wall hook bracket.
NOTE:
Do not bend or crush the indoor unit piping. Avoid
sharp bends with radius of curvature of less than 10 cm.
Do not bend the same part of the pipe too often, after
three times it could be throttled.
Do not remove the flare nut from the indoor unit piping
until immediately before connecting the connection
pipe.

INDOOR UNIT CONDENSED WATER DRAINAGE

YES NO NO
The indoor unit condensed water drainage is
fundamental for the success of the installation.
Install the drain hose at the bottom of the wall hole.
The insulator of the copper pipes should be at least 6
mm thick.
Check that:
The top and bottom hooks of the indoor unit are hooked firmly on the wall hook bracket.
The unit is positioned horizontally. If the unit is not installed properly, water will drip onto the floor.
The drain hose has the correct gradient (at least 3 cm for every meter in length).
The drain hose remains at the bottom of the wall hole.
OUTDOOR UNIT INSTALLATION
4
The outdoor unit should be installed on a solid wall and fastened securely
The following procedure must be observed before connecting the pipes and electric cables:
decide which is the best position on the wall and leave enough space to be able to carry out maintenance easily.
fasten the support to the wall using screw anchors which are particularly suited to the type of wall;
use a larger quantity of screw anchors than normally required for the weight they have to bear: during operation the machine
vibrates and has to remain fastened in the same position for years without the screws becoming loose.

To empty the refrigerant pipe from air and humidity, the use of the vacuum pump is recommended.

Connecting the pipes
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
place.
When extending the rolled pipe, straighten the pipe by
unwinding it gently as shown in the figure below
To avoid leakage, pay particular attention to the following points:
Tighten the flare nuts using two wrenches. Pay attention not to damage the pipes.
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.
The surest system consists in tightening the connection by using a fix wrench and a torque wrench: in this case use the following
table.
CONNECTIONS TO THE INDOOR UNIT
Shape the connection pipe following the diagram.
Remove the indoor unit pipe cap (check that there is no
debris inside).
Insert the flare nut and create a flange at the extreme
end of the connection pipe.
Connect the pipes by using two wrenches.
CONNECTIONS TO THE OUTDOOR
UNIT
Screw the flare nuts to the outdoor unit coupling with
the same tightening procedures described for the indoor
unit.
