WARNING
Disconnect and lock out power supply before performing any installation work.
Working on or near energized equipment could result in death or serious injury.
STEP 1. INSTALL HOUSING (A or B)
A) Hanger Brackets
Hanger brackets allow the fan to be suspended when a mounting surface is not available.
Assemble vibration isolator 3 and hanger bracket to the housing using screw A. Install vibration
isolators 1 and 2 to the hanger bracket. Use the washers provided and anchor bolt (not
included) to secure the housing (Figure 1).
B) Fasten to Joist
Position the housing so the bottom edge is flush with the finished ceiling. Secure with screws
(Figure 2). If necessary, construct a frame around the flange of the housing to provide additional
support.
STEP 3. INSTALL DUCT CONNECTOR & DUCT
Using the recommended duct size, connect duct to the damper/duct connector (Figure 3), and
run duct to an exterior roof or wall cap using the shortest, straightest duct routing possible.
Ensure all duct connections are airtight.
STEP 4. CONNECT WIRING
Refer to wiring diagram on page 4. Reattach all electrical box covers before applying power.
STEP 5. INSTALL GRILLE
Pinch the springs on the sides of grille and insert them into the slots in the housing. Firmly
push the grille against the ceiling to secure (Figure 4).
