FOUR-WAY CEILING-CASSETTE INDOOR UNITS
Installation and Best Layout Practices
Installing Multiple Indoor Units in One Area
Ensure there is enough space between indoor units, lighting fixtures,
and ventilation fans / systems.
Preparing the Installation Area and Hanging the Indoor Unit Frame
Preparing the Installation Area
1. Installation guide (template) depicts the exact dimensions
necessary for the ceiling opening.
2. Choose the location for the indoor unit, and then mark where the
bolts, refrigerant piping, and drain hose should be. Suspension
bolt angle should account for drain direction.
3. Drill holes for the bolts. Use either a W 3/8 inch or a M10 size
bolt.
For easier installation, attach the accessories (except for the
decoration panel) before hanging the indoor unit.
