OPERATION
The humidity control and fan can be operated separately. Use
a 1- or 2-function wall control. Do not use a dimmer switch to
operate the humidity control. See "Connect Wiring" for details.
SENSOR OPERATION
The humidity-sensing fan uses a sophisticated humidity sensor
that responds to: (a) rapid to moderate increases in humidity or
(b) humidity above a set-point. The humidity sensor may
occasionally turn the fan ON when environmental conditions
change.
MANUAL ON WITH TIMED OFF
The humidity sensing fan has an additional operation feature. For
odor or vapor control, the fan can be energized by cycling the
power switch. Once the fan has been energized in this manner, it
will remain on for 20 minutes.
To manually energize the fan:
1. If fan power switch is already ON, proceed to Step 2; otherwise,
turn power switch ON for more than 1 second.
2. Turn fan power switch OFF for less than 1 second.
3. Turn fan power switch back ON and fan will turn ON.
CLEANING & MAINTENANCE
For quiet and effi cient 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.
SENSOR CLEANING
The humidity sensor is mounted in the control housing. The sensor
will operate most reliably when cleaned occasionally as follows:
1. Disconnect power at service entrance.
2. Remove the grille. Use a dry dustcloth, clean toothbrush,
or lightly vacuum to clean sensor and grille. DO NOT USE
ABRASIVE CLOTH, STEEL WOOL PADS, OR SCOURING
POWDERS.
3. DO NOT USE cleaning sprays, solvents, or water on or near
the sensor!
