To provide drainage
INFORMATION
If necessary, you can use a drain pan (field supply) to
prevent drain water from dripping.

sure that the inclination is towards the backside of the unit.
This is required to guarantee proper drainage.
NOTICE
If drain holes of the outdoor unit are covered by a mounting
base or by floor surface, raise the unit to provide a free
space of more than 150 mm under the outdoor unit.

operating efficiency. To prevent this:

Remove the knockout hole (a) by tapping on the attachment
points with a flat head screwdriver and a hammer.

2
Remove the burrs, and paint the edges and areas around the
