Installation Of The Indoor Unit - Daikin F Series Instruction Manual

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 flow as
shown in the diagram.
* Can be smaller than 300mm if ceiling is removable.
Do not install the unit at altitude over 2000m for both indoor and outdoor.
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.
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.
