PREPARATION (Continued)
Installation may vary depending on how the previous bath fan was installed. Supplies necessary for the installation of your
bath fan are not all included; however, most are available at your local home improvement or hardware store.

wires
NOTE: The connector is reusable on solid wires of the
same wire gauge or smaller. Do not reuse the connector
on stranded wires.
• Strip wires 3/8 in. - 1/2 in.
• Grip the wire firmly and push the stripped end of the wire into the
open port of the connector. Use only one conductor per port.
• Verify the stripped end of the wires is fully inserted to the back
of the connector.
CAUTION: Wiring maximum temperature rating 221˚F
(105˚C). 600V maximum for building wiring and 1,000V
maximum for signs and light fixtures. The acceptable wire
range is 12-18 AWG Sol. Cu.

WARNING: Wiring must comply with all applicable
electrical codes. Turn off power before removing or
installing connectors.
WARNING: COPPER TO COPPER ONLY. Do not use
aluminum wire.
CAUTION: Accessory part (quick connector) should
meet installation instructions to the right.
It is recommended to apply proper insulation around the fan to
minimize heat loss and gain. This fan is designed to be installed
using a 4-in. duct.
Using a rigid duct is recommended. Using a flexible duct, cut to
size and/or fully extended is also acceptable. Ducting has a
strong effect on the air flow, noise and energy use of the fan.
Use the shortest, straightest duct routing possible for best
performance. Avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce energy
loss and inhibit mold growth. Fans installed with existing ducts
Wall cap
may not achieve their rated air flow.
