Belt Drive Duct Fan
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 instructions could result in personal injury and/or property damage!
Model BDF Belt Drive Duct Fan
Model BDF is a belt drive duct supply, exhaust or return air fan. These
fans are specifically designed for inline applications. Performance
capabilities range up to 15,000 cfm (25,500 m
(747 Pa) of static pressure. BDF fans are available in seven sizes with
nominal wheel diameter ranging from 8 to 20inches (203to508 mm)
(080 - 200 unit sizes). Each fan shall bear a permanently affixed
manufacture’s engraved metal nameplate containing the model number
and individual serial number.

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.
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 notification 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 and motor. Make sure 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 Chart 1 on page 3 for physical
dimensions (Figure 1) and Chart 3 on page 3 for
dimensions of vibration isolators (Figure 3).
The motor’s amperage and voltage ratings must be
checked for compatibility to supply voltage prior to
final electrical connection. Supply wiring may be routed
through knockouts which are provided on the top and
bottom of each fan housing. Provide adequate wiring
to permit the access doors to open for servicing. Wiring
should be secured inside the fan to prevent interference
with the drive components. 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 - 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 - 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 & 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.
