1. Always mount the rear panel in such way that it is levelled, 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.
Drilling a hole in the wall for the piping
Fig. 10.
1. Indoors
2. Outdoors
1. Make the piping hole (Ø65mm) in the wall at a slight downward slant to the outdoor side.
2. Insert the piping-hole sleeve into the hole to prevent the connection piping and wiring from
being damaged when passing through the hole.
Warning:
The hole must slope downwards towards the exterior
Keep the drain pipe down towards the direction of the wall hole to prevent leakage and to
facilitate water discharge.
Electrical connections
Fig. 11.
1. Front panel
2. Wiring diagram
3. Terminal block cover
1. Open the front panel.
2. Take off the cover as indicated in the picture (by removing a screw or breaking the hooks).
3. For the electrical connections, see the circuit diagram on the right part of the unit under the
front panel.
4. 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.
Note:
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.
The wires can be connected to the main PCB of indoor unit by the manufacturer according to
the model without terminal block.

Refrigerant piping connection
Fig. 12.
Extending the rolled pipe
Fig. 13.
The piping can be run in the 3 directions indicated by numbers in Fig12. When the piping is run
in direction 1 or 3, if necessary, 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.
Note:
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 damage. 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 Fig. 13.
Connections to the indoor unit
1. Torque wrench
Fig. 14.
The connectors should be outdoors
Fig. 15.
1. Remove the indoor unit pipe cap (check that there is no debris inside).
2. Insert the flare nut and create a flange at the extreme end of the connection pipe for the
other tube to fit in it.
3. Tighten the connections by using two wrenches working in opposite directions.
4. For R32/R290 refrigerants, mechanical connectors should be outdoors.
Indoor unit condensed water drainage
Fig. 16.
The indoor unit condensed water drainage is fundamental for the success of the installation.
1. Insert the pipe connection into the relative slot.
2. Press to join the pipe connection to the base.
