Installation

Step 1

Switch power off at service panel and lock the service disconnecting
means to prevent power from being switched on accidentally.

Step 2

In the bathroom, remove the inlet grille.

Step 3

Unplug the motor and remove the motor plate. If convenient, you may
want to remove the motor from the motor plate at this stage.

The motor from your existing fan will not be used when your
retrot installation is complete. However, the motor plate may
be essential for attaching the inlet grille.

3

Step 4

Remove the wiring cover of your existing ceiling mounted bath fan.
Disconnect the power wires to your existing fan.

Step 5

Attach the exible duct provided to the inlet port of the new fan. Tape the
black inner liner to the four inch diameter lip and tape the reective outer
shell to the larger diameter shoulder. Do not leave the insulation material
exposed.

Step 6

Electrical Connection for new fan

A Remove the screws securing the terminal box cover located on

the side of the fan. All fan motor connections are pre-wired to an
electrical terminal strip. Use the cable restraint provided to secure
the wiring through the hole on the electrical box.

B Be sure to place the connector nut over the wiring coming into the

electrical box. There are two open ports on the terminal strip. Using
a small regular screwdriver, tighten the neutral (white) wire of the
incoming supply under the open terminal strip port labeled "N".
Tighten the line (black) wire of the incoming supply under the open
terminal strip port labeled "L". Tighten the ground (green) wire of the
incoming supply under the open terminal strip port labeled with the
Ground symbol. If the terminal strip is not labeled, follow the wiring
diagram found on the inside of the electrical cover.

Step 3

Step 4

VT 20M

C Secure the cable restraint. Secure the incoming supply with the

cable restraint. Replace the fan electrical box cover. All fan motor
and capacitor connections have been pre-wired from the factory. No
additional fan wiring is necessary.

D The other end of the electrical cable will be connected in a later

step.

Step 7

In the attic or crawl space, nd the location of the existing bath fan
and its exhaust duct. Select a location for the new FG 4 fan. The new
fan will be connected to part of the existing exhaust duct so you must
plan to locate the new fan along the line of the existing exhaust duct, no
greater than seven feet from the existing fan. Fan location should allow
sufcient access for service. For applications that require the new FG4
fan to be located more that seven feet from the existing fan, longer
lengths of electrical cable and exible insulated 4” duct can be purchased
separately.
