INSTALLATION TIPS
Indoor Unit
Installation locations include:
S
A location where no obstacles exist near the inlet and outlet
areas.
S
A location which can bear the indoor unit’s weight is critical.
S
Do not install the indoor units near a direct source of heat such as
direct sunlight or a heating appliance.
S
A location which provides appropriate clearances (see Fig. 3).
S
Do not install the indoor unit in a location with special
environmental conditions. For those applications, contact your
Ductless Systems representative.
INDOOR UNIT INSTALLATION
1. Obstructions should be removed from the indoor unit’s intake
or outlet vents so air can flow throughout the room.
2. Ensure the installation is in accordance with the schematic
diagram’s required clearances.
3. Select an install site that can withstand four times the indoor
unit’s weight and would not increase the operating noise.
4. Ensure the unit is level.
5. Select a location where condensated coagulated water can
drain easily away from the outdoor unit.
6. Ensure there is enough space for care and maintenance.
Ensure the height between the indoor unit and ground is
≥
3ft. (1m) or
≤
16ft. (5m).
7. Ensure the install site can withstand a weight four times of
the unit’s. If not, reinforce the site prior to installation. Refer
to the install cardboard to determine where the location
should be reinforced.
IMPORTANT
: To guarantee a good performance, the unit must be
installed by professional personnel in accordance with this manual.
IMPORTANT
: Drilling holes in the ceiling must be performed by
professional personnel.

NOTE
: Adjust the position to ensure the gaps between the indoor
unit and the four sides of the false ceiling are even. The indoor unit’s
lower part should sink into the false ceiling roughly 0.9in (24mm).

NOTE
: Installation is possible with a ceiling dimension of 23.62
in. (600m) (marked with *). However to achieve a ceiling
−
panel
overlapping dimension of 0.59 in (15mm), the spacing between the
ceiling and the unit should be 0.79 in. (20mm) or less. If the
spacing between the ceiling and the unit is over 0.79 in. (20mm),
attach the sealing material in the part or recover the ceiling.
