A. INSTALLING THE MOUNTING PLATE TO A
OUTLET BOX (MOUNTED DIRECTLY TO A
CEILING JOIST)
1. Remove two knock-outs from the outlet box to
expose the joist. (Fig. 4)
2. Use the two #12 X 3" wood screws and washers to
secure the mounting plate directly to the building joist
via the knockout holes from the outlet box. (Fig. 5)
3. Use the mounting plate as a guide to mark the
hole position in the joist.
4. Predrill the holes using a 5/32" drill bit.
B. INSTALLING THE MOUNTING PLATE
DIRECTLY TO AN OUTLET BOX
The outlet box and support structure must be
securely mounted and capable of reliably supporting
a minimum of 35 lb (15.9 kg) or less. Use only
UL-Listed outlet boxes marked "FOR FAN
SUPPORT." (Fig. 6)
WARNING: To reduce the risk of fire, electric shock
or personal injury, mount the fan to the outlet box
marked acceptable for fan support with the screws
provided with the outlet box.
