GENERAL INSTALLATION GUIDELINES

Location Selection
DANGER
To avoid the possibility of fire, do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. Failure to do so will
cause serious bodily injury or death. Before beginning installation, read the safety summary at the beginning of this manual.
Note:
Select a location for installing the indoor unit (IDU) that meets the following conditions:
• 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.
Note:
The unit may be damaged, may malfunctioin, 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 (Figure 7) , 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 malfuction of the condensate drain. If this is
a potential problem, install a ventillation fan large enough to vent out these materials
Do not install the unit where it will be subjected to direct thermal 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, sulfuric gas, or volatile organic compounds (VOC) 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 insulatiion between the floor joists.
Unpack and Inspect for Freight Damage
CAUTION
Table 2 lists shipping and net weights. To help avoid personnel injury and unit damage, use at least two people when carrying a unit by hand.
Note:
Do not unpack the unit and remove protective materials until ready to install. Before opening the shipping container, check the container label-
ing to verify the unit received is the correct unit. Verify the unit capacity, type, and voltage. Refer to the Nomenclature chart on page 11. Before
unpacking, carefully move packaged unit to a work area near installation location. After opening, if unit is damaged, repack unit as it was shipped.
RETAIN ALL PACKING MATERIALS. In general, freight damage claims will be denied if the original packing materials are not retained for the claims
adjustor to inspect. File a freight claim and order a replacement unit.
1. Place the box on a solid surface right side up.
2. Cut the white reinforced nylon straps, open the top of the box, and fold back all four flaps.
