GENERAL INSTALLATION GUIDELINES

Required Indoor Unit Clearances

Indoor Unit Clearances
Follow recommended best practices when choosing an indoor loca-
tion for the single zone indoor unit.
• Where there is enough structural strength to bear the weight of the
unit.
• Operating sound from the unit will not disturb occupants.
• Include enough space for service access.
• Include space for drainage to ensure condensate flows properly out
of the unit when it is in cooling mode.
• Use a level indicator to ensure the unit is installed on a level plane.
• Include space for drainage to ensure condensate flows properly out
of the unit when it is in cooling mode
Note:
The unit may be damaged, may malfunction, and/or will not operate as
designed if installed in any of these conditions:
Do not install the unit near a heat or steam source, or where
considerable amounts of oil, iron powder, or flour are used. These
materials may generate condensate, cause a reduction in heat
exchanger efficiency, or malfunction of the condensate drain. If
this is a potential problem, install a ventilation fan large enough to
vent out these materials
Do not install the unit where it will be subjected to direct ther-
mal radiation from other heat sources.
Do not install the unit in an area where combustible gas may
generate, flow, stagnate, or leak. There is the possibility of fire.
Do not install the unit in a location where acidic solution and
spray (sulfur) are often used.

Do not use the unit in environments where oil, steam, or
sulfuric gas are present.
Do not install additional ventilation products on the chassis of
the unit.
Do not install the unit near high-frequency generator sources.
Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (floors, walls) in some rooms
may be exposed to unconditioned air. The room may be above or
next to an unheated garage or storeroom. To counter
this condition:
• Verify that carpet is or will be installed (carpet may increase
the temperature by three (3) degrees.
• Install radiant heat or another type of heating system to
the floor.
• Add insulation between the floor joists.
Volatile Organic Compounds
Indoor Units (IDUs) must not be placed in an environment where
the IDUs may be exposed to harmful volatile organic compounds
(VOCs) or in environments where there is improper air make up or
supply or inadequate ventilation. If there are concerns about VOCs
in the environment where the IDUs are installed, proper air make up
or supply and/ or adequate ventilation must be provided. Addition-
ally, in buildings where IDUs will be exposed to VOCs consider a
factory-applied epoxy coating to the fan coils for each IDU.
