Application Information
Model: FWC-H
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.
Ceiling Concealed Mounting
•
Use the hanger supplied with the unit.
•
Make sure that the ceiling is sufficiently strong to withstand the weight.
Provide clearance for servicing ease and optimal air flow as shown in the diagram.
Ceiling Concealed Drain Piping Work
•
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 flow.
•
Ensure the drain pipe is securely insulated.
•
It is necessary to provide a drain trap in the drain outlet to relieve pressure that exists within the unit
compared to the outside atmospheric pressure when the unit is operating. The drain trap is to avoid
possibility of splashes or an odor.
•
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 flow is smooth.
•
In humid environments, use an extra drain pan to cover the entire area of the indoor unit.
