All wiring should be installed in accordance with National, State, and Local electrical codes.
Fans used to ventilate livestock buildings or other rooms where continuous air movement is
essential should be connected to individual electrical circuits, with a minimum of two circuits
per room. For electrical connection requirements, refer to diagram on motor nameplate and
to information enclosed with the Aerotech environmental control to be used.
 motor overload protection should be provided for each fan. A Circuit
Breaker Switch or slow blow motor type fuses must be used See Figure 5. See Aerotech
form QM1400 for proper size.  A safety cut-off switch should be located adjacent to
each fan.

1) INITIAL START-UP: With electrical power off, verify that the fan propeller turns
freely and that all fasteners are secure. Turn on electrical power and conrm that
the fan operates smoothly.
2) ADJUSTMENTS: Set the fan control to the temperature shown on your Aerotech
ventilations system drawing, or to a value which will provide the desired
environmental conditions.
When variable speed controls are used, the fan's idle speed will need to be set to
the recommended minimum airow rate. Refer to the procedures included with
each control. The following table provides airow rates at various propeller speeds
for fans wired for 240 VAC:

In most climates, it is probable that the ventilation system will never need to operate at a total capacity during
the colder winter months. Consequently, it is advisable to "winterize" those fans which will not be used in cold
weather to avoid unnecessary heat loss and condensation.
To winterize, turn fan control "off". Install the insulated closure panel over the fan intake. If you don't have an
insulated closure panel, a piece of rigid insulation material can be used. Remember the insulation panel
must be removed before warmer weather returns.
 At least one single speed fan should be left uncovered and with power available to provide air move-
ment in the event of variable speed control difculties.

The following inspection and cleaning procedures should be performed monthly:
1) INSPECT PROPELLER: Check that propeller is secure on motor shaft and that there
are no signs of damage. The blades are of a self-cleaning design and should not
require maintenance.
2) CLEAN regularly for best results:
• FAN MOTOR: Remove any dust accumulation from motor using a brush or cloth.
(DO NOT use a pressure washer). A clean motor will run cooler and last longer.
At the same time, verify that the motor is secure in its mount.
• SHUTTER: Carefully clean dust from shutter blades and frame so that shutter
opens and closes freely. A brush or cloth should be used.
• GUARD: Clean any dust or feathers from fan guards using a brush. Dirty guards
can reduce airow.
3) CHECK FASTENERS: For safety, all fasteners should be inspected. Tighten any
loose connections.
4) INSPECT FAN CONTROL: With power disconnected, inspect all electrical
connections. Wiring should be secure and in good condition. Remove any dust
build-up from control case and sensor using a soft brush or cloth. 
