9.3.4 Making Holes for the Pipes

• Case A: laying the rear piping.

In the event of laying the rear piping, a suitable hole

must be made (see Figure 9.1).

• Drill a hole in accordance with the diameter

indicated in Figure 9.1, slightly descending to the

outside.

Fig. 9.1 Dimensions of the hole for the piping.

• Case B: laying the side or bottom piping.

In this case holes do not have to made on the wall

since the indoor unit body has windows which can be

opened to admit the pipes: choose the most adequate

one for the desired outlet position (see Figure 9.7).

• Carefully break the chosen window on the lid using pliers.

Fig. 9.7 Windows for the installation of the pipes.

9.3.5 Laying the Pipes

• If installing the rear piping:

• Place the lid supplied for the hole in the piping and

insert the coolant pipes with the condensed water

pipe through the hole.

• Seal the hole properly after installing the pipes.

• Carefully bend the installation pipe in the right

direction.

Warning!

Danger of breakdowns or malfunction. Danger of

wear in the coolant pipes.

Bend the pipe carefully to prevent choking or

breaks.

• Cut the pipes, leaving enough extra piping hanging

over to enable the unit to be hooked up at the indoor

unit joins.

• Insert the nut in the coolant pipe and carry out

the flaring.

• Carefully remove the insulation of the flared

connections in the indoor unit.

• Hang the indoor unit on the top edge of the

mounting plate.

• Tilt the lower part of the indoor unit forwards and

insert an auxiliary tool (e.g. a piece of wood) between

the mounting plate and the unit (see Figure 9.8).

Fig. 9.8 Assembling the indoor unit.

• Connect the coolant pipes and the condensed water

hose to the corresponding pipes and installation drain.

• Insulate the coolant piping correctly and separately. To

do so, cover any possible cuts with masking tape or

insulate any bare coolant piping with the

corresponding insulation material used for cooling.
