Installation of hanging bolts
• Consider the piping/wiring after the unit is hung to
determine the location of the indoor unit installation
and orientation.
• The hanging bolt pitches are given in the outline
drawing and the attached installation pattern.
• When a ceiling already exists, lay the drain pipe,
refrigerant pipe, control wires, and remote control
wires to their connection locations before hanging
the indoor unit.
Procure hanging bolts and nuts for installing the indoor
unit (these are not supplied).
Using the installation pattern (accessory)
Using the pattern, positioning of the hanging bolt and
pipe hole can be performed.
* As an error to some degree may generate on the
pattern size due to temperature and humidity, be
sure to confirm the size.
Installation of hanging bolt
Use 3/8” (M10) hanging bolts (4 pcs, to be local
procure). Matching to the existing structure, set pitch
according to size in the unit external view as shown
