GENERAL INSTALLATION GUIDELINES
Hanging the Indoor Unit
• The threaded rod hangars (bolts) and hardware must be securely installed to prevent the frame falling from its location. There is risk of
property damage from falling equipment.
• Ensure the unit is properly installed. Incorrectly installed units can result in degraded performance or an inoperative unit/system.
• Use a level indicator to ensure the frame is installed on a level plane. Incorrectly installed units can result in degraded performance or an
inoperative unit/system.
• Use the provided pattern to determine the size of the ceiling opening and the threaded rod hangar locations required by the unit.
Hanging the Indoor Unit
The following parts are field supplied:
• Hanging bolt - W-3/8" or M10

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, 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).
