INSTALLATION OF THE INDOOR UNIT
The indoor unit must be installed such that there is
no short circuit of the cool discharge. Respect the
installation clearance.
Do not put the indoor unit where there is direct
sunlight on unit. The location is suitable for piping
and drainage and it must have a large distance
between a door and unit.
In cases where the temperature above the ceiling
might reach 30°C or the humidity RH80%, reinforce
the drain pan insulation (10mm or thicker) or adding
secondary Drain Pan. Condensation may form on
the surface of the insulating material.
Provide clearance for servicing ease and optimal air
fl
ow as shown in the diagram.
Ceiling Concealed Mounting
• Use the hanger supplied with the unit.
• Make sure that the ceiling is suf
fi
ciently strong to
withstand the weight.

CAUTION
Do not install the unit at altitude over 2000m for both indoor and outdoor.
Ceiling Concealed Drain Piping Work
DRAIN PIPE
The suggested slope of the
drain pipe is at least 1:50
Insulate securely
10mm (0.39")
• The drain pipe must be installed as shown in the diagram (see diagram above) to avoid damage caused by
leaks and condensation.
• For the best result, keep the piping as short as possible. Slant the piping at an angle to improve the
fl
ow.
• Ensure the drain pipe is securely insulated.
• Keep pipes as straight as possible for easy cleaning and to prevent the accumulation of dirt and debris.
• Conduct a water drainage test after the installation is completed. Make sure that the drainage
fl
ow is smooth.
• In humid environments, use an extra drain pan to cover the entire area of the indoor unit.
