• Attach a nut (M10 or W3/8: not supplied) and 

the Ø34 washer (supplied) to each hanging bolt.

• Insert a washer on both sides of the T groove of 

the hanging bracket of the indoor unit, and hang 
the indoor unit.

• Check that the four sides of the indoor unit are 

level using a level vial (levelness: 5mm or less).

• Detach the installation gauge (accessory) from 

the installation pattern.

• Using the installation gauge, check and adjust 

the positional relation between the indoor unit 
and the ceiling opening (1) (10 to 35mm: 
4 sides) and the hanging-up height (2) 
(

mm: 4 corners).

(How to use the installation gauge is printed on 
the gauge.)
