them from moving during transport.
Once the unit is installed and before making its initial
connection, these fastenings must be removed. To do
so:
1 Loosen the central screws in the supports (painted
yellow) of the tandem compressors without re‐
moving them.
2 Remove the two fasteners -1-.
3 Tighten the central screws until the are completely
screwed in.
4 Check that the tandem compressors are resting
on their antivibration supports.

• All side panels except for that of the electrical box,
must be fitted, closed and secured with their cor‐
responding locks before turning the general switch
on the unit.
• The unit has a remote control, which means that
the fan turbine may start unexpectedly.

Loose connection terminals produce overheating of
cables and terminals. The unit is working incorrectly
and there is a risk of fire.
Check that the cables are firmly secured to their con‐
nection terminals.
