MANUALE DI INSTALLAZIONE
FOR THE AIR CONDITIONER TO OPERATE SATISFACTORILY, INSTALL IT AS OUTLINED IN THIS MANUAL
BE CAREFUL NOT TO SCRATCH THE AIR CONDITIONER UNITS WHEN HANDLING THEM.
CONNECT THE INDOOR UNIT AND THE OUTDOOR UNIT WITH PROPER CORDS AND AIR CONDITIONER PIPING
MOVING A SPLIT AIR CONDITIONER TO ANOTHER LOCATION REQUIRES SPECIAL TECHNIQUE. IF NECESSARY, CONSULT WITH THE SELLER.

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.

WORKING LIMITS: cooling mode - unit operatives up to 43° outdoor temperature
heating mode - unit operatives down to - 5°C outdoor temperature
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.

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.
