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

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.
Note:
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.
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.
1. Arrange the pipes, cables and drain hose well.
