WARNING
INLINE DRYER BOOSTER FAN
Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
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.
Installation work and electrical wiring must be done by a qualified person in accordance with all applicable codes and standards, including fire-rated
construction codes and standards.
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.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
Ducted fans must always be vented to the outdoors.
Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit (ceiling installation only).
CAUTION
WARNING -TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
To ensure quiet operation of ENERGY STAR qualified in-line and remote fans, each fan shall be installed using sound attenuation
techniques appropriate for the installation.
For bathroom and general ventilation applications, at least 8 feet of insulated flexible duct shall be installed between the exhaust or
supply grille(s) and the fan.
For kitchen rangehood remote ventilation applications, where metal duct is generally required by the code, a metal sound attenuator
shall be installed between the rangehood and the fan.
An appropriate duct termination device (roof, cap, wall cap, louvered shutters, etc.) are to be used with this fan. The ducting from this fan
to the outside of the building has a strong effect on the air flow, noise and energy use of the fan.
Use the shortest, straightest duct routing possible for the best performance, avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce engergy loss and inhibit mold growth.
Fans installed with existing ducts may not achieve their rated air flow.
Duct sealant, caulk, or tape should be applied to all seems to prevent air leakage and maximize air performance.
Flex, spiral, or snap lock ducting may be used.
To minimize static pressure losses and promote adequate airflow, minimize duct run lengths where possible. If using flex duct, keep
duct runs straight and taut.
