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 a spacer (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 pipework exiting from the right hand side and
bottom of the unit extend the pipework through the
relevant knock out before hanging unit (see section
9.3.6).
• For pipework exiting from the left of the unit, make
the connections at the rear of the unit first before
hanging the unit (see section 9.3.6).
Note!
The flare connections where possible should be
accessible to allow leak test and future access.
9.3.6 Installation of the Indoor Unit Body
• Check that the installation has been carried out
correctly and that there are no leaks (see section 12.1).
• Securely hang the indoor unit body onto the upper
notches of the mounting plate. Briefly move the body
from side to side to verify that it is secure.
• Lift the body up slightly from underneath, press it
onto the mounting plate and then lower it vertically.
The body will fit into the lower supports on the
mounting plate.
• Check that the indoor unit is properly secured.
• In the event that the body does not slot into the
supports properly, repeat this process.
• Do not use excessive force as this may damage the
fixing lugs, ensure that the pipework is not trapped
behind the unit.
