• If there should be a false ceiling, lift the indoor unit
(see warnings in section 10.1), tilt slightly and introduce
it via the opening in the false ceiling (see figure 10.5).
• Position the indoor unit in such a way that its fixing
supports remain positioned between the nut and the
nut-locknut set (see figure 10.4).
• Regulate lower fixing nuts in such a way that the
indoor unit is horizontally levelled and at the correct
height (flush with the lower part of the false ceiling).
• Tighten the upper fixing nuts and locknuts.
10.8 Connections
• Carefully remove the insulation of the flared
connections in the indoor unit.
• Connect the coolant pipes and the condensed water
hose to the corresponding pipes and installation drain.
• Thermally insulate the coolant pipe and condensed
water connections.
• In the event of installing cold air and bypass lines:
• Cut and remove the anti-condensation insulation in
the indoor unit.
• Connect the lines to the indoor unit (see figure 10.3).
• Carry out the electrical connection (see section 13).
Note!
The connections in the flaring should be
accessible in order to carry out the water
tightness tests.
10.9 Installation of the decorative panel
Warning!
Danger of breakdowns or malfunction.
Danger of condensed water escaping and the
appearance of anomalies in the display.
In order to avoid this, ensure that the decorative
panel is correctly installed.
Note!
Previously, carry out the start up and the
equipment functional test (see section 15).
• Check that the false ceiling is completed and that the
size of the opening is suitable (the opening should not
be visible after assembly of the cover).
• Ensure that the indoor unit is horizontally levelled and
that it is flush with the lower part of the false ceiling
once this has been completed.
• Position the decorative panel in a position which
ensures that the Air Swing motor does not remain
below the coolant pipes.
• Provisionally fix the decorative panel screws and level
the decorative panel.
• Firmly tighten the decorative panel screws.
• Connect the synchronous motor cables and the signal
lines.
• Carry out a function test with the remote control.
• If there is no response to the remote control signal:
check the connection and repeat the function test 10
seconds after disconnecting the power supply.
