CLEANING & 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.
OPERATION
Fan with no accessories — Use an ON/OFF switch to operate this fan. See the wiring diagram on page 4 of this instruction manual.
Fan with ADD on Humidity Sensor and no wall switch (see the wiring diagram on page 5 of this instruction manual)
Fan with ADD on Humidity Sensor and wall switch to manually activate the fan (The fan and humidity sensor can be operated separately
by wall switch. See the wiring diagram on page 4 of this instruction manual for more details)
Humidity Sensor
The humidity-sensing fan uses a sophisticated humidity sensor that responds to: (a) rapid to moderate (adjustable by user) increases in
humidity or (b) humidity above a user-adjustable set-point (50%-100% relative humidity). The humidity sensor may occasionally turn the fan
ON when environmental conditions change. 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 +25ºC)
