Selecting the Best Location

Do’s

• Place the unit where air circulation will not be blocked.
• Place the unit where drainage can be obtained easily.
• Place the unit where noise prevention is taken into consideration.
• Ensure there is sufficient space from the ceiling and floor.
• Ensure there is sufficient maintenance space.
• Locate the indoor unit in a location where it can be easily connected 

to the outdoor unit / heat recovery unit.

Installing in an Area Exposed to Unconditioned Air

In some installation applications, areas (floors, walls) in some rooms may be exposed to unconditioned air (room may be above or next to an 

unheated garage or storeroom). To countermeasure: 
• Verify that carpet is or will be installed (carpet may increase the temperature by three [3] degrees).
• Add insulation between the floor joists. 
• Install radiant heat or another type of heating system to the floor.
