GENERAL SAFETY INFORMATION
1. Make sure that the electric service supply voltage is AC
120V, 60Hz.
2. Follow all local electrical and safety codes, as well as
the National Electrical Code (NEC) and the Occupational
Safety and Health Act (OSH Act).
3. Always disconnect the power source before working on or
near the ventilating fan, motor or junction box.
4. Protect the power cord from sharp edges, oil, grease, hot
surfaces, chemicals or other objects.
5. Do not kink the power cord.
6.
shown in Fig. A.
7. Provide suction parts with proper ventilation.
8. This unit is UL listed for use over a bathtub or shower
when installed in a GFCI-protected branch circuit.
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the
manufacturer. If you have questions, contact the
manufacturer.
2. Before servicing or cleaning unit, switch power off at
service panel and lock the service disconnecting means
to prevent power from being switched on accidentally.

locked, securely fasten a prominent warning device,
such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by
4.
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 local code authorities.
5. When cutting or drilling into the wall or ceiling, do not
damage electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. If this unit is to be installed over a tub or shower, it must
GENERAL SAFETY INFORMATION
be marked as appropriate for the application and be

protected branch circuit.
8. Do not use this unit with any other solid-state control
device. Solid-state controls may cause harmonic
distortion, which can cause a motor humming noise.
9. NEVER place a switch where it can be reached from a
tub or shower.
10. Not to be installed in a ceiling thermally insulated to a
value greater than R50. (This is required for installation
in Canada only).
11. Do not open/disassemble the LED light engine.
CAUTION
1. For General Ventilating Use Only. Do Not Use To Exhaust
Hazardous Or Explosive Materials And Vapors.

PERPARATION AND WIRING DIAGRAMS
Proper insulation around the fan to minimize building
heat loss and gain. The ducting from this fan to the
outside of the building has a strong effect on the air
ow, noise and energy use of the fan. Use the shortest,
straightest duct routing possible for best performance,
and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce
energy loss and inhibit mold growth. Fans installed with
existing ducts may not achieve their rated air ow.

Install the housing (I)-using suspension brackets
1.  Sliding suspension brackets are available to allow
for positioning of the housing anywhere between
joists up to a span of 24”.
2. Insert the suspension brackets into the channels on
the housing. Make sure the tabs face up as shown.
(Fig. C).
3. Extend the suspension brackets to t the width
of the joists. Hold the fan in place by wrapping
the suspension bracket tabs around the bottom
of the joist. Make sure the fan body is level and
perpendicular to the joist. (Fig. D).

7. Follow steps 2 to 6 of the installation instructions to
complete the installation work.
Install the housing (II)-using mounting tabs
1. Slotted tabs are provided to locate housing ush
with 1/2” ceiling material. Bend tabs outwards 90°
(Use a screw driver if desired) and position housing
so that tabs rest against bottom edge of the joists
(or front of the stud). Nail the housing to the joist
or stud using four screws to ensure a solid, quiet
installation. (Fig. E & F).
Install the housing (III)-existing ceiling installation
1. Position the housing so that it is centered in the
existing ceiling opening; make sure the housing is
ush with the nished ceiling. Nail the housing in
place and then drive the nails (not provided) through
the housing where indicated by arrows. (Fig. G).
1. Insert the 6” duct (not provided) into the duct
connector and tape all ductwork connections to
make them secure and airtight. (Fig. H).
2. Install the duct with a gradient 1°~2° to the outside.

OPERATION
Single Models: SMT130, SMT150, SMT150LED
1. Single speed control mode: Turn the POWER switch
on to operate at single speed mode - the LED
indicator will be green.
2. Turn the POWER switch on/off to operate the fan /
LED light / LED night light.
Humidity Model: SMT130H
3. Humidity control mode: Turn the POWER switch
on to operate at humidity control mode - the LED
indicator will be blue. When the ambient humidity
is higher than the user-adjustable set-point, the fan
will run at full speed. When the ambient humidity is
lower than the set-point, the fan will continue to run
at the full speed until a 10-minute time delay has
elapsed, and then will automatically change to the
user-adjustable low speed airow.
4. Full speed mode: Turn the MODE switch on to
operate at full speed mode - the LED indicator will
be amber.

5. Motion control mode: Turn the POWER switch on
to operate at motion control mode. When motion is
detected, the fan will run at full speed mode - the
LED indicator will be amber. When motion is not
detected, the fan will continue to run at the full speed
until the user-adjustable time delay has elapsed, and
then will automatically change to the user-adjustable
low speed airow - the LED indicator will be green.
6. Motion sensor detectible
range: The distance that
motion can be detected
is limited to 10 feet (3m).
The eld of view of the
sensor is 90°. (Room
temperature is 25°C)
Factory setting: low speed airow 70CFM, time delay

7. Low speed control mode: Turn the POWER switch
on (MODE switch is off) to operate at the user-
adjustable low speed airow - the LED will be green.
8. Full speed control mode: Turn the POWER switch &
MODE switch on to operate at full speed mode - the
LED indicator will be amber. When the user turns the
MODE switch off, the fan will continue to run at the
full speed until the user-adjustable time delay has
elapsed, and then will automatically change to the

TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
The fan is not turning on 1. Power off
2. Faulty switch
3. Faulty wire connection
1. Make sure power supply is on.
2. Test or replace switch.
3. Check wire in switch box.
The fan seems louder
than it should
1. CFM too great
2. Damper not working
properly or damaged
3. Bend in duct too close
to fan discharge
4. Fan discharge
reduced to t smaller
duct
5. Fan body not securely
attached
1. Be sure the CFM rating on the fan matches the
size of your room.
2. Check damper to ensure it is opening and closing
properly. If the damper has become damaged,
please call Customer Service.
3. Be sure you do not have any sharp bends in duct
closer than 18 in. to the fan discharge.
4. Use recommended size ducting to reduce fan
noise.
5. Be sure the fan is securely attached to your ceiling
joists.
The fan is not clearing
the room
1. Insufcient intake
airfow within room
2. Insufcient CFM
1. Be sure a door or window is slightly ajar or opened
to allow airow. The fan is not able to draw air out
of the room without enough airow to draw in from.
2. Be sure the CFM rating on the fan matches the
requirements for your room size.
