Selecting installation place
Choose a location that places the outdoor unit as close to the indoor unit as
possible. The maximum unit separation and vertical lift (compressor above the
evaporator) must be taking into account. Do not exceed allowable refrigerant
line lengths.
Indoor unit
• Unit must be installed in a location that does not obstruct the flow of air
and ensures clearances are maintained. (Fig. 1)
• The site must support the weight of the unit.
• The site must be easily accessible for cleaning or replacement of the air
filter, maintenance and service.
• The indoor unit should be mounted as high up on the wall toward the
ceiling, leaving a minimum of 6” (150mm) of space between the ceiling
and the top of the indoor unit. (Fig. 1)
• Due to the possibility of electronic interference with other devices, it is
recommended that there should be at least to 3 ft (1 meter) between the
unit and other devices/appliances such as televisions or radios.
• The unit should be installed away from possible exposure to fire, smoke,
of flammable gases and be protected from direct sunlight (sunlight can
interfere with the signal between the unit and the remote controller.
Outdoor unit
• If installation location allows the unit to be exposed to strong winds (such
as coastal applications), ensure that the unit has a wind barrier. This will
assist with preventing strong gusts of wind from entering the unit’s cabinet
and interfering with the fan operation. (Fig. 3 and Fig. 4)
