Follow recommended best practices when choosing a location for the Gallery and Wall-Mounted Indoor Units (IDU).
To avoid the possibility of re, do not install the unit in an area where combustible gas may generate, ow, 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.
Dos
• Ensure that the wall is solid and has enough structural strength to bear the weight of the installation plate (if applicable) and indoor unit.
• Include enough space for service access.
• Include space for drainage to ensure condensate ows properly out of and away from the unit when it is in cooling mode.
• Use a level indicator to ensure the unit is installed on a level plane.
• Use a stud nder to locate studs easily, preventing unnecessary damage to the wall.
• Install the indoor unit in a location where it can be easily connected to the outdoor unit / heat recovery unit.
Dont’s
Do not install the unit where it will be subjected to direct thermal radiation from other heat sources.
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.
Avoid installing the unit near high-frequency generator sources.
Do not install the unit near a doorway.
Ensure there are no obstacles to air circulation around the unit; keep proper distances from ceilings, doorways, floor, walls, etc.
Do not install in an area where operation sound will disturb occupants--place the unit where noise prevention is taken into consider-
ation.
Do not install the unit near a heat or steam source, or where considerable amounts of oil, iron powder, or flour are used. (These ma-
terials may generate condensate, cause a reduction in heat exchanger efficiency, or the drain to malfunction. If this is a potential problem,
install a ventilation fan large enough to vent out these materials.)
GENERAL INSTALLATION GUIDELINES
Location Selection
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 oor joists.
• Install radiant heat or another type of heating system to the oor.
