Warnings

DO NOT CONNECT POWER SUPPLY until fan is completely installed. Make sure electrical service to the fan is locked in “Off” position

1. All units are suitable for use with solid-state speed control.

2. This unit has rotating parts and safety precautions should be exercised during installation, operation and maintenance.

3. CAUTION: “For General Ventilation Use Only. Do Not Use To Exhaust Hazardous Or Explosive Materials And Vapors.”

4. WARNING: To reduce the risk of fire, electrical shock, or injury to persons-observe the following:

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.

Installation (Cont'd)

Step 8

Using the wood screws provided, attach the mounting bracket to a
support beam at the selected location. Fan mounting can be at any
point along the duct and in any angle, however, vertical mounting is
recommended to reduce condensation buildup in the fan. If a horizontal
installation is necessary and condensation buildup may pose a problem,
either wrap insulation around the fan or drill a 1/4" hole in the bottom
of the housing (along with an NPT insert [by others] and drain tubing)
allowing condensation to drain.

Step 9
Cut the existing duct 8” above the mounting bracket. Make a second cut
in the duct at approximately 12” from the existing fan, and then remove
this middle section of the existing duct.

Step 10

Attach fan to the mounting bracket with the sheet metal screws provided.
Wiring box should be positioned for easy access. Screws are self tapping
and do not require pilot holes. However, pilot holes (no larger than 3/32" )
are recommended.

Step 11

Connect the section of the existing duct (from the roof cap, wall cap
or soft vent) to the outlet port of the new fan using duct tape. If your
existing exhaust duct is 3” diameter, use one of the 3” to 4” adapters
(supplied in the kit).

Step 11 & Step 12

Screw Location

Step 12

Connect the section of the existing duct (from the discharge of the
existing fan) to exible duct (from the inlet on the new fan) using duct
tape. If your existing exhaust duct is 3” diameter, use one of the 3” to 4”
adapters (supplied in the kit). Tape the black inner liner to the four inch
diameter lip and tape the reective outer shell over the top of the inner
liner. Do not leave the insulation material exposed.

Step 13

Uncoil the new electrical cable from the new fan. Loosen the cable
restraint on the existing fan and feed 4” of the new cable through the
restraint, next to the existing electrical cable. Tighten the screws on the
cable restraint of the existing fan.

Step 14

In the bathroom, connect the new cable to the existing power supply
(black wire to black wire, white wire to white wire) using the wire nuts
provided.

Step 15

Carefully push the new connections back into the fan housing (or wiring
box within the fan housing) making sure that no wires will be pinched
before putting the wiring cover and motor plate back into position.
Reattach the fan grille.

Step 16

Install the VT20M fan controller in an electrical box upstream of the fan.
See also the instructions included with the VT20M controller.

Step 13

Step 17

Restore electrical service, switch on and verify airow
