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 effects
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.

Model BSQ Belt Drive

Model BSQ is a belt drive centrifugal inline
exhaust fan. These fans are specifically
designed for inline applications.
Performance capabilities range up to
27,200 cfm (46,200 m

4.0 in. wg (996 Pa) of static pressure.
BSQ fans are available in fourteen
sizes with nominal wheel diameter

ranging from 7 to 42 inches (178 to
1067 mm) (070 to 420 unit sizes). Each fan shall bear
a permanently affixed manufacturers engraved metal
nameplate containing the model number and individual
serial number.

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

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 Greenheck Representative.
Any physical damage to the unit after acceptance is not
the responsibility of Greenheck Fan Corporation.

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 the SQ & BSQ Fan Dimensions
table on page 3 for physical dimensions, utilizing
Figures 1 and 2. Mounting dimensions and vibration
isolator centerline information is provided on pages
4 and 5. 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.

Fan 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 in. (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.

Outdoor Storage

Fans designed for outdoor applications may be stored
outdoors, if absolutely necessary. Roads or aisles for
portable cranes and hauling equipment are needed.

The fan should be placed on a level surface to prevent
water from leaking into the fan. The fan should be
elevated on an adequate number of wooden blocks so
that it is above water and snow levels and has enough
blocking to prevent it from settling into soft ground.
Locate parts far enough apart to permit air circulation,
sunlight and space for periodic inspection. To minimize
water accumulation, place all fan parts on blocking
supports so that rain water will run off.

Do not cover parts with plastic film or tarps as these
cause condensation of moisture from the air passing
through heating and cooling cycles.

Fan wheels should be blocked to prevent spinning
caused by strong winds.

Inspection and 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® 506 (Ashland Inc.) or the equivalent. For
hard to reach internal surfaces or for occasional use,
consider using Tectyl® 511M Rust Preventive, WD-40
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.
