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. To reduce the risk of fire, use only metal ductwork.

be controlled using an on/off switch or a solid-state, variable speed
control. Follow wiring instructions packed with control, and adhere
to all local and state codes, and the National Electrical Code.

disconnect from power supply before servicing.

To clean grille: Use appropriate vacuum attachment or remove

grille and clean with a soft cloth and mild soap or detergent. Dry
grille thoroughly before reinstalling.

To clean blower assembly: Remove grille, unplug blower from
housing, remove blower mounting nuts, and carefully remove blower
from housing. Use appropriate vacuum attachment or a soft cloth
and mild soap or detergent to clean blower discharge area and
wheel. DO NOT ALLOW WATER TO ENTER MOTOR. Make sure
blower assembly is completely dry before reinstalling.

Motor is permanently lubricated. Do not oil or disassemble motor.
