2 Unit installation
Where a false ceiling is already installed, install and prepare the pipes and cables on the indoor unit before lifting it.
C A U T I O N
• Before lifting the unit, prepare any necessary means (ladders, scaffolding, elevator platform, etc.) and check
that the current safety regulations in the place where the installation is taking place are met.
• Check that the lifting work can be carried out without the risk of injuries to you or others in the surrounding
area.
• Request the assistance of another person to lift the unit.
Lift the unit carefully, without exercising pressure on the drain pan.
Fit the nuts, flat washers and spring washers supplied (4 of each)
to secure the indoor unit.
Check that the condensate discharge system in the indoor unit
works correctly. To do so, check the level of the drain pan using a
spirit level.
Adjusting the space between the indoor unit and the opening in the false ceiling
Adjust the indoor unit to the correct position using the template for
the installation.
For panelled ceilings.
Once adjusted, tighten the suspension bracket nuts.
Apply a thread-locking product to the bolts and nuts to prevent them from loosening. Otherwise, abnormal noise may be
caused by mechanical vibrations and the indoor unit may become loose.
