INSTALLATION
9.3.5 Correct installation of indoor unit
refrigerant pipe work
If installing the rear exiting piping:
• Place a seal ring 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:
b
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 9.9) to allow access to the unit
connections.
Fig. 9.9 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 to Air heat
pumps installations (for connection of the electrical wiring
see section 11).

• 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).

• 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.
