GENERAL INSTALLATION GUIDELINES
Required Indoor Unit Clearances
Follow required best practices when choosing an indoor location for the
single zone extended piping indoor unit.
Do's
• Minimum clearance of indoor unit from the top of the unit to the
ceiling must be greater than 8 inches.
• Clearance gap between any wall or enclosure and the left or right
side of the unit must be greater than 4 inches. Ensure there is
sufficient maintenance space.
•
• Place the unit where drainage can be obtained easily. Condensa-
tion drain must be conveniently routed away from the unit.
• Locate the indoor unit in a location where it can be easily connect-
ed to the outdoor unit within allowable limits.
• Install the indoor unit on a strong, hard wall that can withstand its weight. Use a metal detector to locate studs in the walls. Anchor unit
following stud location to prevent damage to the wall.
Do Not's
• 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
will 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.)
• 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 consideration
• Do not install near doorway.
• Avoid installing the unit near high-frequency generators.
corrosive gases are generated, vented into, or stored. There is risk of
The unit will be damaged, will malfunction, and / or will not
operate as designed if installed in any of the conditions
listed.
•
Indoor units (IDUs) must not be placed in an environment where the IDUs will 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 envi-
ronment where the IDUs are installed, proper air make up or supply and/or adequate ventilation must be provided. Additionally, in buildings
where IDUs will be exposed to VOCs, consider a third party factory-applied epoxy coating to the fan coils for each IDU where the entire coil
is dipped, not sprayed.
• If the unit is installed near a body of water, the installation parts are at risk of corroding. Appropriate anti-corrosion methods must be taken for
the unit and all installation parts.
Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (floors, walls) in some rooms will be exposed to unconditioned air (room will be above or next to an
unheated garage or storeroom). To countermeasure:
• Verify that carpet is or will be installed (carpet could 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.
