3.1 Combinations of Outdoor Units and Indoor Units
The combination capacity of the indoor unit against the outdoor unit is selected depending on the outdoor
unit capacity. Refer to the "Installation and Maintenance Manual" for the outdoor unit to decide the required
combination of indoor and outdoor units, and the combination unit capacity.
3.2 Transportation and Handling
•
Transport the product as close to the installation location as possible before unpacking.
•
Do not lay any objects on the indoor unit.
•
The indoor unit comes crated upside-down with the foam polystyrene condensate pan positioned on top.
Do not invert the unit until it is ready to be suspended above the floor. Inverting the unit while on the
floor will crush the condensate pan. Do not handle the unit by grabbing the polystyrene pan and other air
outlets as they are fragile and will sustain damage.
•
The indoor unit handle is made from foam polystyrene and is susceptible to breakage if any excessive
force is applied as a result of mishandling of the unit during installation.
