INSTALLATION INSTRUCTIONS
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
SECTION 1
Preparing for Fan Installation
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).
