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 these instructions will result in voiding of the product warranty and may result in personal injury

and/or property damage.

Belt Drive Duct Fan - Supply, Exhaust or Return Air

Belt drive duct fans are designed for low sound levels in supply,

exhaust or ducted return applications. Units feature forward curved

wheels and galvanized steel housing.

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.

Belt Drive Duct Fan2

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 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 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.

Prestart-Up Checks

1. Check all fasteners for tightness. The wheel

should rotate freely and not rub on the fan

panel venturi. Turn the fan on momentarily to

check for unusual vibration or noise. Do not

run the fan more than a few seconds without

being connected to the system for which it was

designed. Motor overloading and burnout may

result from lack of system static pressure.

2. Inlet and discharge collars are provided for duct

connection. The inlet panel is removable for

attaching optional ﬁlter box accessory.

3. Wheel Rotation: Direction of wheel rotation is

critical. Check wheel rotation by momentarily

energizing the unit. Improper rotation will result in

reduced airﬂow and pressure capabilities. Rotation is

always in the same direction as airﬂow at the outlet.

See housing and wheel examples in Figure 4.

WARNING

Correct direction of wheel rotation is critical. Reversed

rotation will result in poor air performance, motor

overloading and possible burnout.

AVERTISSEMENT

La turbine doit impérativement tourner dans le bon

sens. Une rotation en sens inverse entraînerait de

mauvaises performances de soufflage, une surcharge

du moteur voire un grillage du moteur.

4. Vibration Isolators: After fan is moved to desired

location, punch out the four knock-out holes which

are located on the unit top and bottom panels.

Assemble the brackets to the unit according to

the appropriate drawings on page 3 and refer to

respective parts list on page7. Make certain all

connectors are tight and that all washers are in.

5 If adjustments are made, it is very important to check

the pulleys for proper alignment. Misaligned pulleys

lead to excessive belt wear, vibration, noise and

power loss. (See Figure 5).

6. Belt tension can be adjusted by loosening four

fasteners (see Figure 6) on the drive frame. The

motor plate slides on the slotted adjusting arms.

Belt tension should be adjusted to allow 1/64 inch

of deﬂection per inch of belt span. For example,

a 15 inch belt span should have 15/64inch (or

about 1/4 inch) of deﬂection with moderate thumb

pressure at mid-point between pulleys (see Figure7).

Overtightening will cause excessive bearing wear

and noise. Too little tension will cause slippage at

start-up and uneven wear.

7. The adjustable motor pulley is factory set for the

RPM speciﬁed. Speed can be increased by closing

or decreased by opening the adjustable motor

sheave. Two groove variable pitch pulleys must be

adjusted an equal number of turns open or closed.

Any increase in speed represents a substantial

increase in the horsepower required by a unit. Motor

amperage should always be checked to avoid

serious damage to the motor when speed is varied.

Belt Drive Duct Fan 5

IMPORTANT

The fan has been checked for mechanical noises at

the factory prior to shipment. If mechanical noise

should develop, suggested corrective actions are

offered in the Troubleshooting section.

IMPORTANT

Over tightening will cause excessive bearing wear and

noise. Too little tension will cause slippage at start-up

and uneven wear.

IMPORTANT

Adjust (tighten) belt tension after the first 24-48 hours

of operation.

Operation

1. Before starting up or operating fan, check all

fasteners for tightness. In particular, check the

setscrews in wheel hub (and pulleys, if applicable).

2. While in the OFF position or before connecting the

fan to power, turn the fan wheel by hand to be sure it

is not striking the venturi or any obstacle.

3. Start the fan and shut it off immediately to check

rotation of the wheel with directional arrow in the

motor compartment, see Figure 4.

4. When the fan is started, observe the operation and

check for any unusual noises.

5. With the system in full operation and all ductwork

attached, measure current input to the motor and

compare with the nameplate rating to determine if

the motor is operating under safe load conditions.

6. Keep inlets and approaches to fan clean and free

from obstruction.

Inspection

Inspection of the fan should be conducted at the

ﬁrst 30 minute and 24 hour intervals of satisfactory

operation.

30 Minute Interval - Inspect bolts, setscrews and motor

mounting bolts. Adjust and tighten as necessary.

24 Hour Interval - Check all internal components and

inspect belt alignment and tension. Adjust and tighten

as necessary.

Maintenance

Installation and maintenance are to be performed only

by qualiﬁed personnel who are familiar with local codes

and regulations and who are experienced with this type

of equipment.

Motor maintenance is generally limited to cleaning

and lubrication (where applicable). Cleaning should be

limited to exterior surfaces only. Removing dust buildup

on motor housing ensures proper motor cooling.

Greasing of motors is only intended when ﬁttings are

provided. Many fractional horsepower motors are

permanently lubricated and should not be lubricated

after installation. Motors supplied with grease ﬁttings

should be greased in accordance with manufacturers’

recommendations. Where motor temperatures do not

exceed 104°F (40°C), the grease should be replaced

after 2,000 hours of running time as a general rule.

Wheels require very little attention when moving clean

air. Occasionally, oil and dust may accumulate causing

imbalance. When this occurs the wheel and housing

should be cleaned to ensure smooth and safe operation.

All fasteners should be checked for tightness each ime

maintenance checks are performed prior to restarting

unit.

A proper maintenance program will help these units

deliver years of dependable service.

DANGER

Always disconnect, lock and tag power source before

servicing. Failure to disconnect power source can

result in fire, shock or serious injury.

WARNING

This unit should be made non-functional when

cleaning the wheel or housing (fuses removed,

disconnect locked off).

IMPORTANT

Uneven cleaning of the wheel will produce an out of

balance condition that will cause vibration in the fan.

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’entretien.

AVERTISSEMENT

NOTE: If unusual environment conditions exist (extreme

temperature, moisture or contaminants) more frequent

lubrication is required.

A good quality lithium base grease, conforming to NLGI

Grade 2 consistency, such as those listed here may be

used.

Belt/Bearing Maintenance

1. Belts tend to stretch after a period of time. They

should be checked periodically for wear and

tightness. When replacing belts, use the same type

as supplied with the unit.

2. Matched belts should always be used on units with

multi-groove pulleys.

3. For belt replacement, loosen the tensioning device

enough to allow removal of the belt by hand. Do not

force belts on or off. This may cause cords to break,

leading to premature belt failure.

4. Once installed, adjust belts as shown in “Prestart-Up

Checks.”

5. Shaft bearings can be classiﬁed in two groups:

relubricating and non-relubricating. Bearings on sizes

80 through 180 are factory lubricated and require

no further lubrication under normal use (between

-20° and 180°F (-29°and 82°C) in a relatively clean

environment. Bearings on size 200 are relubricatable.

These bearings will require frequent lubrication.

Caution should be employed to prevent overpacking

or contamination.

6. Grease ﬁttings should be wiped clean. The unit

should be in operation while lubricating. Extreme

care should be used around moving parts.

7. Grease should be pumped in very slowly until a slight

bead forms around the seal. A high grade lithium

base grease should be used.

WARNING

Before taking any corrective action, make certain unit

is not capable of operation during repairs.
