Installation, Operation and Maintenance Manual

Please read and save these instructions for future reference. Read carefully before attempting to assemble, install,
operate or maintain the product described. Protect yourself and others by observing all safety information. Failure
to comply with these instructions will result in voiding of the product warranty and may result in personal injury
and/or property damage.

Square Centrifugal Inline Fans

Fans include both direct- and belt-driven options with backward-inclined
wheels and feature rugged construction, high-efficiency and low sound
levels. These compact inline fans are the ideal selection for indoor clean
air applications including intake, exhaust, return, or make-up air systems.
The square housing design, compact size, and straight-thru airflow also
provide the system designer the flexibility to mount in horizontal and
vertical orientations. Each fan displays a permanently stamped metal
nameplate with complete model number, mark, and unique serial number
for future identification.

General Safety Information

Only qualified personnel should install this fan.
Personnel should have a clear understanding of these
instructions and should be aware of general safety
precautions. Improper installation can result in electric
shock, possible injury due to coming in contact with
moving parts, as well as other potential hazards. Other
considerations may be required if seismic activity
is present. If more information is needed, contact a
licensed professional engineer before moving forward.

1. Follow all local electrical and safety codes, as well as
the National Electrical Code (NEC) and the National
Fire Protection Agency (NFPA), where applicable.
Follow the Canadian Electric Code (CEC) in Canada.

2. The rotation of the wheel is critical. It must be free
to rotate without striking or rubbing any stationary
objects.

3. Motor must be securely and adequately grounded.

4. Do not spin fan wheel faster than max cataloged fan
RPM. Adjustments to fan speed significantly affects
motor load. If the fan RPM is changed, the motor
current should be checked to make sure it is not
exceeding the motor nameplate amps.

5. Do not allow the power cable to kink or come in
contact with oil, grease, hot surfaces or chemicals.
Replace cord immediately if damaged.

6. Verify that the power source is compatible with the
equipment.

7. Never open access doors to a duct while the fan is
running.

DANGER

Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power
source can result in fire, shock or serious injury.

CAUTION

When servicing the fan, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.

CAUTION

Precaution should be taken in explosive atmospheres.

DANGER

Pour écarter les risques d’incendie, de choc électrique
ou de blessure grave, veiller à toujours débrancher,
verrouiller et étiqueter la source de courant avant
l’installation ou l’entretien.

ATTENTION

Lors de toute intervention sur la soufflante, le moteur
peut être suffisamment chaud pour provoquer une
douleur voire une blessure. Laisser le moteur refroidir
avant toute maintenance.

ATTENTION

Faire preuve de précaution dans les atmosphères
explosives.

Receiving

Upon receiving the product check to ensure all items
are accounted for by referencing the delivery receipt or
packing list. Inspect each crate or carton for shipping
damage before accepting delivery. Alert the carrier
of any damage detected. The customer will make
a notation of damage (or shortage of items) on the
delivery receipt and all copies of the bill of lading which
is countersigned by the delivering carrier. If damaged,
immediately contact your local representative. Any
physical damage to the unit after acceptance is not the
responsibility of the manufacturer.

Unpacking

Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing, report shortages to your local representative to
arrange for obtaining missing parts. Sometimes it is not
possible that all items for the unit be shipped together
due to availability of transportation and truck space.
Confirmation of shipment(s) must be limited to only
items on the bill of lading.

Handling

Move fan to desired location and determine position of
access panels, discharge and motor. Make sure the inlet
and outlet have at least 2½ times the wheel diameter
(duct diameter) before any obstructions like an elbow
or transition. Attach the fan to a suitable framework
as specified; hanging or base vibration isolators are
recommended. See corresponding Fan Dimensions
tables; pages 3 and 4 for physical dimensions. Mounting
dimensions and vibration isolator centerline information
is provided on pages 5 and 6. The motor’s amperage
and voltage ratings must be checked for compatibility
to supply voltage prior to final electrical connection.
Electrical lead-in wires are then connected to the factory
supplied safety disconnect switch. All wiring must
conform to local and national codes.

Storage

Fans are protected against damage during shipment. If
the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of
the unit during storage. The user assumes responsibility
of the fan and accessories while in storage. The
manufacturer will not be responsible for damage during
storage. These suggestions are provided solely as a
convenience to the user.

Indoor Storage: The ideal environment for the storage
of fans and accessories is indoors, above grade, in a
low humidity atmosphere which is sealed to prevent
the entry of blowing dust, rain or snow. Temperatures
should be evenly maintained between 30° to 110°F
(-1° to 43°C) (wide temperature swings may cause
condensation and “sweating” of metal parts). All
accessories must be stored indoors in a clean, dry
atmosphere.

Remove any accumulations of dirt, water, ice or snow
and wipe dry before moving to indoor storage. To avoid
“sweating” of metal parts allow cold parts to reach room
temperature. To dry parts and packages, use a portable
electric heater to get rid of any moisture buildup. Leave
coverings loose to permit air circulation and to allow for
periodic inspection.

The unit should be stored at least 3½ inches (89 mm)
off the floor on wooden blocks covered with moisture
proof paper or polyethylene sheathing. Aisles between
parts and along all walls should be provided to permit
air circulation and space for inspection.

Inspection & Maintenance During Storage

While in storage, inspect fans once per month. Keep a
record of inspection and maintenance performed.

If moisture or dirt accumulations are found on parts,
the source should be located and eliminated. At each
inspection, rotate the wheel by hand ten to fifteen
revolutions to distribute lubricant on motor. If paint
deterioration begins, consideration should be given to
touch-up or repainting. Fans with special coatings may
require special techniques for touch-up or repair.

Machined parts coated with rust preventive should be
restored to good condition promptly if signs of rust
occur. Immediately remove the original rust preventive
coating with petroleum solvent and clean with lint-free
cloths. Polish any remaining rust from surface with
crocus cloth or fine emery paper and oil. Do not destroy
the continuity of the surfaces. Thoroughly wipe clean
with Tectyl
hard to reach internal surfaces or for occasional use,
consider using Tectyl
or the equivalent.

Removing From Storage

As fans are removed from storage to be installed in their
final location, they should be protected and maintained
in a similar fashion until the fan equipment goes into
operation.
