MODEL: AP80-QVL
AP80H-QVL
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, PLEASE READ THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or
telephone number listed in the warranty. 2.Before servicing or cleaning unit, switch power off at service panel and lock the service
disconnecting means to prevent power from being switching on accidentally. If the service disconnecting means cannot be 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 a licensed person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and
standards. 4. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning
equipment to prevent backdraft. 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. Acceptable for use over a tub or
shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit. 8. This unit must be grounded. 9.
Never place a switch where it can be reached from a tub or shower. 10. WARNING: To reduce the risk of fire or electric shock, do not
use this fan with any solid-state speed control device. 11. The fan must not be installed in a ceiling thermally insulated to a value
greater than R40.
CAUTION
1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. This product is designed for installation in ceilings up to a 12/12 pitch (45 degree angle). Duct connector must point up for wall
application.
3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall and construction dust away of motor unit.
4. Please read specification label on product for further information and requirements.
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.
OPERATION
Use an on/off switch to operate this fan. See “Connect Wiring” for details.
The humidity control and fan can be operated separately. Can be used with a dual “stacked” switch for fan / light control. Do not use
a dimmer switch
to operate the humidity control or light. See “Connect Wiring” for details.
For AP80H-RVL
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 rate 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,
adjustment may be required. The fan is factory-set for 75% (with a ambient temperature of 77 degree F)
SENSITIVITY ADJUSTMENT (H)
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 ambient temperature changes, the humidity sensor values will deviate slightly.
TIMER ADJUSTMENT (T)
The “T” on the control panel will adjust the time delay from 5 to 60 minutes (factory pre-set at 20 minutes). This “T” controls the
length of time that the
fan remains ON after the sensor has stopped sensing a rise in humidity and the humidity level is below the user-adjustable set-point.
To adjust the “T”:
1. Disconnect power at service entrance;
2. Through the grille, locate the slot marked “T”;
3. Carefully rotate the “T” adjustment to desired setting (from 5 to 60 minutes).
4. Check operation by turning on a humidity source until the fan turns on.
5. Turn humidity source off and time the unit.
6. Repeat above steps if necessary.
