- The height of the unit's lower edge from the floor must be
at least 4”.
- If fixed to the wall in the highest position, it must be at
least 3.5” from the ceiling.
- The wall on which the inside unit is installed must be
sturdy and able to withstand its weight.
- It must be possible to leave room around the unit for any
maintenance operations that may be necessary.
- Nothing can be in the way of the air that needs to circulate
both on the top air-intake (curtains, plants, furniture) and at
the front where the air exits. This could cause air swirls that
would inhibit the working efficiency of the unit.
