3. Installation work and electrical wiring must be done
by qualified person(s) in accordance with all
applicable codes and standards, including fire-rated
construction.
4. 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.
5. When cutting or drilling into 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 be marked as appropriate for the application
and be connected to a GFCI (Ground Fault Circuit
Interrupter) – protected branch circuit.
8. Do not use this unit with any other solid-state
control device. Solid-state controls devices may
cause harmonic distortion, which can cause a motor
humming noise.
9. NEVER
NEVERNEVER
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).
CAUTION
1. For General Ventilating Use Only. Do Not Use To
Exhaust Hazardous Or Explosive Materials And
Vapors.
2. Not for use in cooking area. (Fig. B)
3. This product must properly connect to the

Operation
Humidity tolerance is about ±10%. Long-time operation
will influence the detecting precision as dust accumulates.
The humidity switch may need to be adjusted.
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 full
speed until a 10-minute time delay has elapsed, and then
will automatically change to the user-adjustable low speed
airflow.
Full speed mode:
Turn the MODE switch on to operate at full speed
mode-the LED indicator will be amber.
MAINTENANCE
WARNING:
Disconnect the power source before working on the unit.
Routine maintenance must be done every year.
CAUTION:

CAUTION:
1. Never use gasoline, benzene, thinner or any other
such chemicals for cleaning the ventilating fan.
2. Do not allow water to enter the motor.
3. Do not soak resin parts in water over 140
o
F (60°C).
