(2) Make sure the range of the unit’s external static pressure is
not exceeded.
(See the technical documentation for the range of the
external static pressure setting.)
(3) Open the installation hole. (Pre-set ceilings)
● Once the installation hole is opened in the ceiling where the
unit is to be installed, pass refrigerant piping, drain piping,
transmission wiring, and remote controller wiring (It is not
necessary if using a wireless remote controller) to the unit’s
piping and wiring holes.
See “5. HOW TO PROCESS TUBING”, “3-22. Installing the
Drain Pipe” and “4. ELECTRICAL WIRING”.
● After opening the ceiling hole, make sure ceiling is level if
needed. It might be necessary to reinforce the ceiling frame
to prevent shaking.
Consult an architect or carpenter for details.
