Receiving and Inspection

This publication contains the installation, operation
and maintenance procedures for the CAV Fan.
Carefully read this publication prior to installation
and carefully inspect the fan and accessories for
any damage and shortage immediately upon
receipt of the fan.

Checklist:

1. Turn the wheel by hand to ensure it turns freely

and does not bind.

2. Inspect dampers (if included) for free operation of
all moving parts.

3. Remove shipping tape and plastic material.

4. Record on the Delivery Receipt any visible sign of
damage BEFORE CARRIER DEPARTS.
Storage

If the fan is stored for any length of time prior to
installation, store it in its original shipping crate and
protect it from dust, debris and weather.

WARNING

This unit has rotating parts. Safety precautions
should be exercised at all times during installation,
operation, and maintenance. ALWAYS disconnect
power prior to working on fan.

Electrical Supply

Check that the voltage and circuit details on
the fan are suitable for your supply.
Caution:
turned off.

Wiring

All wiring should be carried out in compliance
with regulations for electrical installations and
comply with any local requirements.
Caution: Never work on a fan unless power is
turned off.

Starting

All fans are suitable for direct starting by
switch or direct line starter.

Personal Safety
Disconnect switches are recommended. Place

the disconnect switch near the fan so that the
power can be swiftly cut off in case of an
emergency, and also so that maintenance personnel
are provided complete control of the power.

Never work on a fan unless power is

Fan Installation Notes:

1. The CAV utility blowers are shipped completely

assembled and ready for installation.

2. Blower unit should be secured to a solid base to
prevent vibration and noise.

3. The motor mount stand provides four (4)
holes to securely fasten the fan in place. Use
screws, bolts, or nails as needed, to secure the
blower.

4. Use appropriate connectors and ducting for the
applications to connect the fan inlet and outlet.

5. Wiring instructions are included with each utility
blower and are also permanently attached to the
motor . Observe and follow wiring instructions and
all codes that apply. Never attempt to install or
remove a blower unit with the power source
turned on.

6. Verify that power source meets motorplate
electrical requirements.

7. Always use finger guard on inlet/outlet when
the unit is running. Do not place hands, fingers,
or other objects into the inlet or outlet. Serious
injury may occur!

8. If the CAV Series utility is installed outside or
in an aggressive environment, it is recommended
that the motor be protected by means of a
weather cover.

9. Housing may be rotated to any 8 positions by
removing back plate screws from the housing.
Rotate housing to desired position, recaulk the
motorplate to fan housing, and reconnect
motorplate nuts.

1. Rotating

The impeller direction of rotation, looking into the hub
of the blower, should be clockwise(CW).

2. Mounting

All fans are suitable for mounting in any plane.

3. Operation

All fans are suitable for internal or external use. The fans
are designated to operate in a temperature range of ­25F to +200F .

4. Ductwork Connection

In order to excess noise and vibration along the
ductwork, we recommend the use of flex connector at
the fan inlet and outlet.

*When connecting duct to inlet and outlet, it is
recomended to install three (3) straight duct
diameters length of pipe to minimize system effect.

5. Operation

The CAV Series utility blower is designed for continuous
duty and may be started and stopped by various on/off
switch devices.

Caution

Most CAV motors have auto thermal overload protection
(TOP). Should the blower overheat the motor will stop
operation and will start again automatically, once the
motor cools down. Always turn power off before
attempting to work on the unit! Installation should prevent
introduction of foreign materials into the air stream. If
foreign materials are present, damage to the blower may
result. Appropriate filters and guards should be in place
during blower operation.
