(3) Create a gap between the wall, screw in the temporary screws (M5, field supply), and hang the MS box.
(4) After checking with a level that the MS box is horizontal, fix the unit with 8 screws (M5, field supply).

2.3 Indoor Units
2.3.1 Placement considerations
Placement of indoor units should take account of the following considerations:
Sufficient space for drain piping and for access during servicing and maintenance should be allowed.
To ensure a good cooling/heating effect, short-circuit ventilation (where outlet air returns quickly to a unit's air inlet)
should be avoided.
To prevent excessive noise or vibration during operation, suspension rods or other weight-bearing fixings should
typically be able to bear twice the unit's weight.
Notes for installers
Before installing an indoor unit, check that the model to be installed is as specified in the construction drawings
and confirm the correct orientation of the unit.
Ensure that units are installed at the correct height.
To allow smooth condensate drainage and to ensure unit stability (to prevent excessive noise or vibration), ensure
that units are level to within 1° of the horizontal. If a unit is not level to within 1° of the horizontal, water leakage
or abnormal vibration/noise may occur.
