• Set the locations for the above holes, open them up and then lay the piping (refrigerant) and wiring
(including both power supply and transmission wiring) up to the piping and wiring connections in the unit.
• It might be necessary to reinforce the ceiling frame to maintain the levelness and to prevent vibration.
Consult an architect or carpenter for details.

make sure that the weight of the unit can be supported. Adjust the distance to the ceiling beforehand.
