Ceiling Exhaust and Inline Fans
PN 461342
Installation, Operation and Maintenance Manual
Prepare the Fan
1. If power assembly (motor, wheel, and scroll) is not
installed in housing, insert the electrical plug into fan
socket, then slide scroll end of power assembly into
fan housing. Attach by using two sheet metal screws
provided, as shown in figure 1.
2. Remove either top or side wiring knockout,
depending on wiring direction, by bending it back and
forth to break tabs, as shown in figure 2.
3. Check duct work to see if the fan’s discharge needs
to be rotated from horizontal to vertical discharge, as
shown in figure 3. To rotate from horizontal to
vertical discharge, remove the two screws holding
the power assembly in, and pull power assembly out.
Rotate power assembly 180 degrees and put back into fan. Use the
same screws to reattach
power assembly to fan
housing. Flip fan over and
remove the four screws
holding the discharge duct
and damper assembly.
Exchange the assembly with
plate mounted on top of fan,
as shown in figure 4.
4. If fan is to be used in a fire
resistive membrane ceiling, a ceiling radiation damper must be
used. If the ceiling radiation damper is already mounted to the fan
from the factory, proceed to next step. To mount the ceiling
radiation damper to fan, make sure grille attachment tabs are
facing down. Then place the inlet part of the fan into the ceiling
radiation damper collar, and use the self-tapping sheet metal
screws provided to screw through the damper collar and into the
fan housing, as shown in figure 5. If the fan/light combination is
being used, make sure ceiling radiation damper has a electrical
plug in it. The electrical plug must be inserted into the fan. Make
sure the electrical wire will not interfere with damper operation, as
shown in figure 6.

WARNING !
To reduce the risk of fire, electric shock, or injury to
persons, observe the following:
• If a speed controller is used, this fan should only be
used with fan speed control, manufactured by KB
Electronics, Inc.
• Before servicing or cleaning unit, switch power off at
service panel and lock service disconnecting means
to prevent power from being switched 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 qualified person(s) in accordance with all
applicable codes and standards, including fire-rated
construction.
• The combustion airflow needed for safe operation of
fuel burning equipment may be affected by this
unit's operation. 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 or other hidden utilities.
• This unit is suitable for use directly over a tub or
shower with a GFI branch circuit wiring. (Up through
size SP-A390)
• Ducted fans must always be vented to the outdoors.
• For general ventilating use only. Do not use to
exhaust hazardous or explosive materials and
vapors.
• These fans are not recommended for cooking
exhaust applications. They are designed primarily
for low temperature, clean air applications only. The
diagram shows the minimum distance these fans
should be placed in relation to cooking equipment.
• Fan/Light combination not to be installed in a ceiling
thermally insulated to a value greater than R40.
