Install so that the EL. COMPO. BOX lid is facing down.
(2) After considering whether the location the unit is to be installed can support its weight, if it seems
dangerous, install it after reinforcing the location with boards, crossbeams, etc.
(3) Avoid any contact with the ceiling surface, as this may cause noise and vibration.
[CAUTIONS]
• Install the indoor and outdoor units, power supply wiring, transmission wiring and remote controller wiring
at least 1 meter away from televisions or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not be sufficient enough to eliminate the noise.)

5. PREPARATIONS BEFORE INSTALLATION
(1) Check the relative locations of ceiling hole, unit, and hanging bolts.
(2) Open the eyebolt holes or the holes for passing the piping and wiring out of the unit.
• 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. (See
“7. REFRIGERANT PIPING WORK”
and
“8. ELECTRIC WIRING WORK”
for details.)
• It might be necessary to reinforce the ceiling frame to maintain the levelness and to prevent vibration.
Consult an architect or carpenter for details.
(3) Install the hanging bolts. (Use M8 hanging bolts.)
• If it is pre-set, use hole-in anchors. Otherwise, use embedded inserts or embedded foundation bolts to
make sure that the weight of the unit can be supported. Adjust the distance to the ceiling beforehand.
