3.1 Combination of Outdoor Unit and Indoor Unit
The combination capacity of 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 drain pan positioned on top.
Do not invert the unit until it is ready to be suspended above the oor. Inverting the unit while on the oor
will crush the drain pan. Do not handle the unit by grabbing at the polystyrene pan and other air outlets
as they are fragile and will sustain damage.
•
The indoor unit handle is fabricated from foam polystyrene and is susceptible to breakage if any
excessive force is applied as a result of mishandling of the unit during installation.
