For New Ceilings
1. Use a sunken insert, a sunken anchor, or any other field-supplied part to
reinforce the ceiling so that it can bear the weight of the indoor unit. Use a
temporary washer plate to more easily set up the unit suspension location.
2. Ceiling height is shown on the side of the installation guide (template). Adjust
the height of the unit accordingly. Adjust the clearance before hanging the
indoor unit.
3. Refer to the installation guide (template) for the dimensions to the ceiling
opening. Match the center of the indoor unit (labeled) to the center indicated
on the installation guide.
4. Align the installation guide (template) with the label attached to the unit (af-
fixing the template to the unit if desired) to properly place the unit.
5. Remove the temporary washer plate and position the indoor unit hanger
brackets on the bolts. Secure with nuts and washers on the top and bottom
of the hanger brackets.
6. Ceiling-cassette indoor units are equipped with a built-in drain pump and
float switch, therefore, the unit must be installed horizontally or condensate
will drip out and cause product malfunction. Measure the unit at each corner
to verify that it is level.
7. Remove the installation guide (template).
For Existing Ceilings
1. Use anchors when installing the indoor unit in an existing ceiling.
2. Ceiling height is shown on the side of the installation guide (template). Adjust the height of the unit accordingly. Adjust the clearance

and bottom of the hanger brackets.
