INSTALLATION INSTRUCTIONS
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT SERVICE
PANEL BEFORE STARTING INSTALLATION.
SECTION 1
Preparing the Exhaust Fan
1. When selecting fan mounting location, the following criteria should be
considered:
a)
Mounting to minimize noise generated by fan operation:
Mounting the fan as far as possible from the intake point will
minimize fan operating noise from being transmitted back
through the duct work. If the fan is to be used as a booster for
moving the air between two rooms, a central point along the duct
may be optimal. Insulated flexible type duct work (recommended
for all bathroom exhaust applications) will result in much quieter
operation. It is recommended that a minimum 8’ of insulated
flexible ducting be used between any exhaust grill and fan for low
noise level.
b)
Service accessibility:
Fan location should allow sufficient
access for service.
SECTION 2
Installing the Fan
1. Using the 1" wood screws provided, attach the fan mounting bracket
to a support beam at the selected location
(Figure 1).
NOTE:
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, wrap insulation around the fan to minimize buildup.
2. Attach fan to the mounting bracket with the three 7/16" sheet metal
screws provided, making sure the wiring box is positioned for easy
access
(Figure 2).

NOTE:
Bracket is provided with rubber vibration isolation grommets to
prevent the transmission of sound through the structure. Be careful not
to over tighten. Also, care should be taken not to strip the plastic housing.
Screws are self tapping and do not require pilot holes. Pilot holes no larger
than 1/16" can be used to ease the installation however.
SECTION 3
Installing Supply/Exhaust Grill
1. Select the grill mounting point within the area to be ventilated that
does not interfere with a ceiling joist. To ease installation, locations of
framing beams within the walls or joists supporting the ceiling should
be considered. Collar/damper is provided with a perforated hanging
strap for attachment directly to a beam or joist. Allow sufficient space
between the collar/damper and the beam to attach the duct work.
If the location of the grill does not allow direct attachment, a cross-
member mounted to the framing should be used.
2. Bend the mounting straps attached to the collar outward so they are
straight across
(Figure 3).
SECTION 4
New Construction
1. Install the collar/damper in the selected location using the provided
1" wood screws through the mounting strap. The mounting height is
determined by the thickness of the final wall/ceiling material. Ensure
that the edge of the collar/damper will be flush with the finished wall/
ceiling material
(Figure 4).
2. Once the wall/ceiling material is in place, install the grill into the collar
by pushing it firmly inward towards the collar until it fits flush against
the wall/ceiling material
(Figure 5).
