Maintenance
For quiet and efficient operation, long life, and attractive appearance - lower or remove grille and vacuum interior of unit with the dusting brush
attachment.The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace
the motor with the exact service motor. The impeller should also be replaced.
Keep all electrical components away from water. Do not use corrosive chemicals or water in excess of 60C (140°F) to clean plastic
parts.
Operation
See “Connect Wiring” for details.
The control box, located inside the fan housing, has three separate
adjustments:
(1) The low airflow knob(s) adjusts the lower airflow from 40CFM up to
the air flow rate of the high fan speed determined by the toggle switch
setting.
(2) The Humidity Sensor Knob set user adjustable setpoint (50%-100%
relative humidity).
(3) The toggle switch will adjust the upper fan speed setting from
80 to 140 CFM.
MOTION SENSOR
The fan will run continuously at the pre-set low speed. When motion is
detected, the fan speed increases to high speed. When the person exits the
area, the fan remains working at high speed until the delay time has passed
(20 minutes). After the time delay, the fan speed is reduced to the
continuous ventilation rate. Installation distance: 7 to 9 feet. Sensing range
is within the cone angle of 90°
HUMIDITY SENSOR OPERATION
The humidity-sensing fan uses a sophisticated humidity sensor that responds
to: (a) rapid to moderate (user-adjustable) increases in humidity or (b)
humidity above a user-adjustable set-point (50%-100% relative humidity).
The fan run continuously, at a preset lower level (set by the low speed
control Knob) and automatically boost up to high speed when environmental
conditions change. After delay timer (20 minutes), the fan returns to the
default low speed. If the fan continuously responds to changing environmental
conditions, “H” (means “humidity”) adjustment may be required. This figure is
factory-set for about 75% (Ambient temperature of 25°).
SENSITIVITY ADJUSTMENT
The “H” has been factory set for most shower applications. However, if the
fan is in a tub area or is being used for dampness control, the “H” may need
to be increased toward maximum “+”. If the control is responding too often
to changing environmental conditions, movement toward less “-” “H” may be
required. To adjust the “H”:
1. Disconnect power at service entrance.
2. Through the grille, locate the slot marked “H”.
3. Carefully rotate the “H” adjustment toward “+” or “-”.
4. Turn on power and check operation by turning on the shower or other
humidity source until the fan turns on.
5. Repeat above steps if necessary.
When the temperature changes, humidity sensor values will have deviation.
