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.
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 or a clear flexible pipe full of water. The side of the unit on which the drain hose is located must be around
5 mm lower than the front side.
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.
Apply protective paint to the bolts and nuts to prevent rusting.
Secure the drain hose with the clamp and adhesive supplied.
