Do not install the unit in a place where an
inflammable gas leaks.
• If gas leaks and accumulates in the area
surrounding the unit, it could cause an
explosion.
Perform the installation securely referring to
the installation manual.
• Incomplete installation could cause a personal
injury due to fire, electric shock, the unit falling or
a leakage of water.
Install the unit securely in a place which can
bear the weight of the unit.
• When installed in an insufficient strong place,
the unit could fall causing injured.
Use the specified wires to connect the indoor and outdoor
units securely and attach the wires firmly to the terminal
board connecting sections so the stress of the wires is not

• Incomplete connecting and fixing could cause
fire.
Check that the refrigerant gas due not leak
after installation is completed.
Perform electrical work according to the
installation manual and be sure to use an
exclusive circuit.
• If the capacity of the power circuit is insufficient
or there is incomplete electrical work, it could
result in a fire or an electric shock.
Attach the electrical part cover to the indoor
unit and the service panel to the outdoor unit
securely.
• If the electrical part cover if the indoor unit and/or
the service panel if the outdoor unit are not
attached securely, it could result in a fire or
electric shock due to dust, water, etc.
Be sure to use the part provided or specified

INSTALLATION OF INDOOR, OUTDOOR UNIT
Read completely, then follow step by step.
Select the best location
1. Indoor unit
■ Do not have any heat or steam near the
unit.
■ Select a place where there are no
obstacles in front of the unit.
■ Make sure that condensation drainage can
be conveniently routed away.
■ Do not install near a doorway.
■ Ensure that the space around the left and
right of the unit is more than 5cm. The unit
should be installed as high on the wall as
possible, allowing a minimum of 5cm from
ceiling.
■ Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
■ Rooftop Installations:
If the outdoor unit is installed on a roof
structure, be sure to level the unit. Ensure the
roof structure and anchoring method are
adequate for the unit location. Consult local
codes regarding rooftop mounting.
Piping length and elevation
2. Outdoor unit
■ If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is
not restricted.
■ Ensure that the space around the back
and sides is more than 10cm. The front of
the unit should have more than 70cm of
space.
■ Do not place animals and plants in the
path of the warm air.
■ Take the air conditioner weight into
account and select a place where noise
and vibration are minimum.
■ Select a place so that the warm air and
noise from the air conditioner do not
disturb neighbors.
Install the indoor unit on the wall where the
height from the floors more than 2.3 meters.

How to fix installation
plate
The wall you select should be strong
and solid enough to prevent vibration
1. Mount the installation plate on the
wall with four type A screws. If
mounting the unit on a concrete wall,
use anchor bolts.
■ Mount the installation plate
horizontally by aligning the centerline
using a level.
2. Measure the wall and mark the
centerline. It is also important to use
caution concerning the location of
the installation plate-routing of the
wiring to power outlets is through the
walls typically. Drilling the hole
through the wall for piping
connections must be done safely.
Drill a hole in the wall
■ Drill the piping hole with a ø70mm
hole core drill. Drill the piping hole at
either the right or the left with the hole
slightly slanted to the outdoor side.
