Drop Ceiling Exhaust Connection
Warning: Some ceilings may require modified installation procedures. The user must
determine the fitness of hardware and procedures before installing. The procedures
described in this manual may not be appropriate for all applications.
4-1
Choose a removable drop ceiling panel near the unit to provide the straightest, shortest path
availablefortheexibleexhaustduct.Measurethewidthoftheceilingpanel,including
the portion that rests on the ceiling grid. Combine the two sections of the adjustable
exhaust panel, then adjust the exhaust panel to match the width of the ceiling panel. After
the exhaust panel is set to the correct width, use the included nut and bolt to lock it in
place. Note: The exhaust panel can adjust from 26.6 to 49.2 inches (67.5 to 125 cm).
4-2
Insert the exhaust duct adapter into the oblong hole in the adjustable exhaust panel. The
adapter will snap into place.
4-3
Slide the ceiling panel out of the way and place the exhaust panel inside the ceiling space.
Allow the exhaust panel to rest on top of the ceiling grid. Note: There must be at least 10
inches (25.4 cm) of open space above the exhaust panel to allow adequate airflow.
4-4
Slide the ceiling panel back into place so that it adjoins the exhaust panel and closes any
gaps in the ceiling. A tight seal will permit maximum cooling efficiency. If the installation
is permanent, trim the ceiling panel so it doesn’t overlap the ceiling grid.
Note: The flexible exhaust duct can extend to a maximum length of 118 inches (300 cm). Provide
the straightest, shortest path available. Excessive bending or stretching of the duct will reduce
cooling efficiency.
