WARNING -TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a). Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer
b). 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. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.
c). Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated
construction codes and standards.
d). Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting.
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.
e). When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
f). Ducted fans must always be vented to the outdoors.
g). Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit (ceiling installation only).
h). This unit must be grounded.
i). Not for Use in Kitchens.
j). To reduce risk of fire and to properly exhaust air, be sure to duct air outside – Do not vent exhaust air into spaces within walls or ceilings or into attics,
crawl spaces, or garages
k). WARNING: To Reduce The Risk Of Fire Or Electric Shock, Do Not Use This Fan With Any Solid-State Speed Control Device.
l). The fan must not be installed in a ceiling thermally insulated to a value greater R40.
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.
3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.
4. Please read specification label on product for further information and requirements.

with 6" duct
The control box, located inside the fan housing, has three separate adjustments:
(1) The low airflow knob adjusts the lower airflow from 40CFM up to the air flow
rate of the high fan speed determined by the toggle switch setting.
(2) (a)The time delay knob is adjustable from 3 to 30 minutes and will switch the
fan to the low speed setting after the set period of time(for model PCD110X).
(b)The humidity sensor knob set user-adjustable setpoint(for model PCD110H).
(3) The toggle switch will adjust the upper fan speed setting from 90 to 140 CFM .
For model PCD110XH
1) Fan run continuously at a low speed(adjustable by low airflow knob) and automatically boost up to high speed when either of these
conditions is detected: a)Humidity above a user-adjustable setpoint (50%-100% relative humidity). b) rapid to moderate (user-adjustable)
increases in humidity .After delay timer (20 minutes) returns fan to the default low speed.Humidity sensor description accroding to
“HUMIDITY SENSOR OPERATION” and“SENSITIVITY ADJUSTMENT”.
2) When the switch is turned on, the fan will run at high speed. When the switch is turned OFF, fan will continue to run at the certified airflow
rate until the delay timer (20 minutes) has elapsed,and then will automatically change to the user-adjustable airflow rate.
For model PCD110X
To Turn Fan ON
Turn the switch I ON.(according to the following “CONNECT ELECTRICAL WIRING”)
• Fan will run at the certified airflow rate if the switch II is ON.
• Fan will run at the user-adjustable airflow rate if the switch II is OFF.
To Use Fan Time Delay Airflow Rate Change
1. Turn the switch I ON.
2. Turn the switch II ON - fan will run at the certified airflow rate.
3. When the switch II is turned OFF, fan will continue to run at the certified airflow
rate until the user-adjustable time delay has elapsed, and then will automatically
change to the user-adjustable airflow rate.
To Turn Fan OFF
Turn the switch I OFF
