Installation
Fans should be installed in an exterior wall located
where there will be no obstructions to the flow of
air into or out of the fan.
Once a location has been determined; an opening
should be made in the wall and framed to provide
enough clearance around the fan housing
.
Opening Chart page 12)
Framing must be able to support the weight of the
fan assembly.
Manual handling of the fans may result in serious
injury. Where appropriate, use mechanical methods
of lifting during installation. Where manual
handling is required enure you have adequate
assistance.
Position fan assembly in the framed opening.
Rigidly mount the housing side flanges to the
framework using mounting screws.
Remove electrical cover and connect power leads
to motor terminals using approved wiring method.
It is recommended to use the Watertight Connector
included with the motor if it is possible in your
application.
(Motor terminal connection data is provided on
. Use adequate size wire for all branch

and feeder runs. When speed control is used, follow
the installation procedures recommended by the
speed control manufacturer.
Re-install electrical cover.
Unit is now ready for operation.
Operation
Units may be operated using a switch, thermostat,
timer, or controller.
Follow wiring and operation instructions furnished
with the control system selected.
When using speed controllers, follow the
(See Rough
operation procedures recommended by the
controller manufacturer.
Set thermostat setting to a desired temperature.
Fan will operate only when ambient temperature
is above the thermostat set temperature.
Some controllers have idle speed controls. Set
idle speed such that the blade RPM is within the
RPM range listed in the Performance Table.
Cleaning
It is advisable to clean blade and shutter at regular
intervals. This will remove any accumulated dirt,
which would cause fan blade to become unbalanced
and result in excessive vibration and poor
performance.
Lubrication
Motor is prelubricated at factory and will not
require any further lubrication.
Safety in Maintenance
While the APP Fan is designed to keep maintenance
to a minimum, some repairs will be necessary in
the course of the life of the machine. Do not attempt
any repairs on the machine unless you are
competent to do so. Remember that the APP Fan
may in cases operate under automatic control and
will start without warning. Never attempt any work
on the APP Fan without first isolating the machine
from the mains power, and locking the isolator so
that only you can turn the power back on.
