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 (affixing 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
before hanging the indoor unit.
3. 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.
4. Ceiling-cassette indoor units are equipped with a built-in drain pump and float switch, therefore, the unit must be installed horizontally or
