9.3.4 Making Holes for the Pipes
• Case A: Pipework exiting from the rear of the unit.
In this case, a suitable hole must be made in the wall
behind the unit (see Figure 9.1).
• Drill a hole in accordance with the diameter and
position as indicated in Figure 9.1, ensure the hole
is slightly descending to the outside to allow for a
fall in the drain line.
Fig. 9.1 Dimensions of the hole for the piping.
• Case B: Running the pipework out of either side or the
bottom of the unit.
In this case holes do not have to made in the wall
since the indoor unit body has knock outs which can
be opened to allow the pipes to exit the unit: choose
the most convenient one for the desired outlet
position (see Figure 9.7).
• Carefully break the knock out in the casing using pliers.
Fig. 9.7 Windows for the installation of the pipes.

9.3.5 Correct Installation of Indoor Unit Refrigerant
Pipe Work
• If installing the rear exiting piping:
• Place the seal ring supplied for the hole in the piping
and insert the coolant pipes with the condensed
water pipe through the hole.
• Remember to seal the hole inside and out properly
after installing the pipes.
• Carefully bend the installation pipe in the right
direction, taking care not to overbend or kink the pipe.
Warning
!
Danger of breakdowns or malfunction. Danger of
damage to the coolant pipes.
Bend the pipe carefully to prevent kinking or
breaks.
• There should be sufficient pipe tails on the indoor unit
to go through the wall width. If this is not the case
connect further lengths of pipe as required. Carefully
feed the pipe tails through the holes together with the
condensate pipework and interconnecting electrical
cable.
• 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) to
allow access to the unit connections.
Fig. 9.8 Assembling the indoor unit.
• Connect the coolant pipes from the outdoor unit and
the condensed water hose to the installation drain.
• Insulate the coolant piping and joints correctly and
separately. To do so, cover any possible cuts with
masking tape or insulate any bare coolant piping with
the corresponding insulation material suitable for air
conditioning installations (for connection of the
electrical wiring see section 11).
