Installation Diagram


The purchaser must ensure that the person and/or company who is to install, maintain or repair this air conditioner has qualifications and experience in refrigerant products.
INSTALLATION MANUAL---Installation of the Indoor unit
Before starting installation, decide on the position of the indoor and outdoor units, taking into account the minimum space reserved around the units.

Do not install your air conditioner in a wet room such as a bathroom or laundry etc.

The installation site should be 250cm or more above the floor.
To install, proceed as follows:
Installation of the mounting plate
1 Always mount the rear panel horizontally and vertically.
2. Drill 32 mm deep holes in the wall to fix the plate.
3. Insert the plastic anchors into the hole.
4 .Fix the rear panel on the wall with provided tapping screws.
5. Be sure that the rear panel has been fixed firmly enough to withstand the weight.
Note : The shape of the mounting plate may be different from the one above, but installation method is similar.
Drilling a hole in the wall for the piping
- Make the piping hole ( 50) in the wall at a slight downward slant to the outdoor side.
- Insert the piping-hole sleeve into the hole to prevent the connection piping and wiring from being damaged when passing through the hole.

The hole must slope downwards towards the exterior.
Note : Keep the drain pipe down towards the direction of the wall hole, otherwise leakage may occur.
Electrical connections---Indoor unit
- Open the front panel.
- Take off the cover as indicated in the picture (by removing a screw or breaking the hooks).
- For the electrical connections, see the circuit diagram on the right part of the unit under the front panel.
- Connect the cable wires to the screw terminals by following the numbering. Use wire size suitable to the electric power input (see name plate on the unit) and according to all current national safety code requirements.

The cable connecting the outdoor and indoor units must be suitable for outdoor use.

The plug must be accessible also after the appliance has been installed so that it can be pulled out if necessary.

An efficient earth connection must be ensured.

If the power cable is damaged, it must be replaced by an authorised Service Centre.



INSTALLATION MANUAL---Installation of the Indoor unit
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 1 or 3, 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
- Remove the indoor unit pipe cap (check that there is no debris inside).
- Insert the fare nut and create a flange at the extreme end of the connection pipe.
- 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.
- Place the drain hose below the piping, taking care not to create siphons.
- The drain hose must slant downwards to aid drainage.
- 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.
- 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.


Extending the rolled pipe


INSTALLATION MANUAL---Installation of the Indoor unit
INSTALLATION OF THE INDOOR UNIT
After having connected the pipe according to the instructions, install the connection cables. Now install the drain pipe. After connection, lag the pipe, cables and drain pipe with the insulating material.
- Arrange the pipes, cables and drain hose well.
- Lag the pipe joints with insulating material, securing it with vinyl tape.
- Run the bound pipe, cables and drain pipe through the wall hole and mount the indoor unit onto the upper part of the mounting plate securely.
- Press and push the lower part of the indoor unit tightly against the mounting plate.

Diagram of a brick wall joint with a tool, showing no text or symbolsINSTALLATION MANUAL---Installation of the outdoor unit
- The outdoor unit should be installed on a solid wall and fastened securely.
- The following procedure must be observed before connecting the pipes and connecting 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 to aviod vibration during operation and remain fastened in the same position for years without the screws becoming loose.
- The unit must be installed following the national regulations.
Outdoor unit condensed water drainage (only for heat pump models)
The condensed water and the ice formed in the outdoor unit during heating operation can be drained away through the drain pipe.
- Fasten the drain port in the 25mm hole placed in the part of the unit as shown in the picture.
- Connect the drain port and the drain pipe. Pay attention that water is drained in a suitable place.

INSTALLATION MANUAL---Installation of the outdoor unit
ELECTRICAL CONNECTIONS
- Remove the handle on the right side plate of outdoor unit.
- Connect the power connection cord to the terminal board. Wiring should fit that of indoor unit.
- Fix the power connection cord with wire clamp.
- Confirm if the wire has been fixed properly.
- An efficient earth connection must be ensured.
- 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:
- 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 table on page 28.
BLEEDING
Air and humidity left inside the refrigerant circuit can cause compressor malfunction. After having connected the indoor and outdoor units, bleed the air and humidity from the refrigerant circuit by using a vacuum pump.
