INDOOR UNIT INSTALLATION
Indoor Unit Hanger Mounting
Depending on the type of ceiling, attach the threaded hanger bolts securely to the support stud. Before
lifting the indoor unit to the installation location, insert the upper nuts, flat washers (with insulation),
flat washers (without insulation), lower nuts and double locking nuts on the threaded hanger bolts.
Lift the Ceiling Cassette main body to the threaded hanger bolts. Insert the unit mounting brackets
between washers and then fasten it securely.
NOTE: The hanger bolts, nuts, and washers are field supplied. Install the washer with
cushion so that the insulation faces downward.
1. Adjust the height of the Indoor Unit main body to align with false ceiling. Be sure to confirm
this, otherwise condensation may form during cooling mode. Adjust mounting nuts as needed.
2. Confirm that the indoor unit main body is level. Adjust mounting nuts as needed.
3. After checking the positioning of the indoor unit main body, tighten the nuts of the hanger
bolts securely to fasten the Indoor Unit main body in place.
