GENERAL SAFETY INFORMATION

When using electrical appliances, basic precautions

should always be followed to reduce the risk of fire,

electric shock and injury to person, including the following:

6. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.

7. Ducted fans must always be vented to the outdoors.

8. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off
power unit.

3. Before servicing or cleaning the unit, switch power off at
service panel and lock the service disconnecting means to
prevent power from being switched on accidentally. When
the service disconnecting means cannot be locked, securely
fasten a prominent warning device, such as a tag, to the
service panel.

4. Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable codes
and standards, including fire-related construction.

5. Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment
to prevent back drafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those
published by the National Fire Protection Association (NFPA)
and the American Society for Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE), and the local code authorities.

CAUTION: FOR GENERAL VENTILATING USE ONLY. DO

NOT USE TO EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS
AND VAPORS.

9. Acceptable for use over a bathtub or shower when installed
in a GFCI protected branch circuit.

10. Suitable for use with solid-state speed control.

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

12. Guards must be installed when fan is within reach of personnel
or within seven (7) feet of working level or when deemed
advisable for safety.

13. NEVER place a switch where it can be reached from a tub or
shower.

14. Do not insert or allow fingers or foreign objects to enter the
motor.

WARNING: DO NOT USE IN KITCHENS

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.

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.

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).

(Figure 1).

Joist

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).

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL

AND NATIONAL BUILDING CODES.
NOTE: Insulated ducting is required for bathroom exhaust

applications, where ducting passes through unconditioned space
or where noise is a factor. Failure to use insulation could result
in excessive condensation buildup within the duct, and
undesirable sound levels within the room. Duct runs should have
as few bends as possible.

NOTE: Flexible insulated ducting may be used where allowed
by local code. For the quietest possible installations, it is
recommended a minimum of 8' of insulated flexduct be used
between any exhaust grill and fan. When using flexible type
duct work, duct should be stretched as tight and straight as
possible. Failure to do so could result in dramatic loss of system
performance. Flexible duct should be connected to the fan with
screw clamps or duct tape. All connections should be as airtight
as possible to maximize system performance.

1. Connect one end of the ducting (not included) to the room
level collar/damper and the other end to the “Y” transition.
Secure both ends in place using tape or a screw clamp to
create as air tight a seal as possible. Repeat this step for the
other room level grill housing (Figure 7).

SECTION 5

Existing Construction

1. Place the collar/damper in the selected location and trace
a circle onto the surface. From the interior side of the room,
cut through the surface. Please note: Take care not to damage
the ceiling and make a smooth cut (Figure 6).

Figure 6

2. Position the collar/damper in the previously cut hole so that
it is flush with the finished ceiling and secure to the joist/stud
using the provided 1" wood screws through the mounting
strap (Figure 4).

3. Install the grill
towards the collar until it fits flush against the wall/ceiling
material

into the collar by pushing it firmly inward

(Figure 5).

NOTE: Units that include only one collar do not utilize the “Y”

connect the one end of the ducting directly to the fan.

2. Connect one end of the ducting to the top of the “Y” transition
and the other end to the intake of the fan (Figure 7).

3. Connect one end of the ducting to the exhaust of the fan and
the other end to a wall or ceiling cap (Figure 7). Always duct
the fan to the outside through a wall or roof cap.

NOTE: When using insulated flex duct, it is recommended that
the inner vinyl core be screw clamped or taped to the inlet and
outlet and that the vapor barrier surrounding the insulation be
taped to the fan housing.

NOTE: When attaching flex duct to the collar/damper combination
and an immediate elbow is necessary, be certain that the elbow is
installed with a "soft" bend to allow damper blades to operate properly.

Installing Optional Balancing Damper

Some kits include an optional balancing damper to allow for
adjustment of the system. The damper may be used where the
grills will be connected using branches of unequal length or
where the flow will need to be balanced for any reason. To Install
the optional damper:

1. The damper must be installed on the branch with the least
restriction. This is generally the duct that is shortest or has
the fewest bends.

2. Drill a 5/16" hole approximately 1-1/2" from the edge on the
flat side of the “Y” transition.

3. Insert the shaft of the damper into the hole drilled in step 2. Place
the washer, handle, then wing nut onto the shaft (Figure 8).

2. Run wiring from an approved wall switch carrying the
appropriate rating. One neutral (white) and one hot (black
lead connected to the switch). Secure the electrical wires
to the housing with an approved electrical connector. Make
sure you leave enough wiring in the terminal box to make the
connections to the fan’s pre-wired electrical terminal strip.

3. Insert the white wire from the house into the terminal strip port
labeled “N” and tighten using a small regular screwdriver. Insert
the black wire from the wall switch into the terminal strip port
labeled “L” and tighten using a small regular screwdriver. Since
the motor is isolated within a plastic housing, grounding is not
necessary

(Figure 10).
