• Record on the Delivery Receipt any visible sign of damage.

XLWH shown

Rotating Parts & Electrical Shock Hazard

Disconnect electric power before working on unit.

Follow proper lockout / tagout procedures to ensure the unit cannot be energized while being installed or

serviced.

A disconnect switch should be placed near the fan in order that the power can be swiftly cut off, in case of an emergency and in order that maintenance personnel are provided complete control of the

power source.

Grounding is required. All eld-installed wiring must be completed by qualied personnel. All eld installed wiring must comply with National Electric Code (NFPA 70) and all applicable local codes.

Failure to follow these instructions could result in

death or serious injury.

Handling

Lift propeller wall fans by attachment to the power

assembly or by the shipping carton. Never lift by the shaft, motor or housing.

Storage

If the fan is stored for any length of time prior

to installation, coat the shaft with grease or a rust

preventative compound. Store it in its original shipping crate and protect it from dust, debris and the weather.

Rotate the wheel several revolutions every three to ve

days to keep a coating of grease on all internal bearing

parts.

Installation

Fans mounted to a wall require a different wall opening

size than fans mounted in wall collars or wall housings. For specic dimensions, refer to the submittal drawing for the specic fan type.

Motor Installation

To prevent damage to the fan during shipping, motors 5

HP and larger, and extremely heavy motors (cast iron or

severe duty) are shipped loose and must be eld mounted

by bolting the motor on the motor mounting plate in the

existing slots.

The motor should be mounted in order that the motor

plate is between the fan shaft and the motor shaft.

1. Remove the motor plate mounting bolts and motor plate.

2. Remove the motor mounting bolts from the motor plate.

3. Mount the motor to the motor plate aligning the appropriate holes.

4. Place the motor plate on the power assembly and reinstall the mounting bolts.

Belt and Pulley Installation

Belt tension is determined

by the sound of the belts

when the fan is rst started. The belts will produce a loud

squeal, which dissipates after the fan is operating at

full capacity. If belt tension

is too tight or too loose, lost

efciency and damage can occur.

Do not change the pulley

pitch diameter to change tension. The change will result in a different fan speed.

1. Loosen the motor plate

adjustment nuts on motor base and move motor plate in order that the belts can easily slip into the grooves

on the pulleys. Never pry,

roll, or force the belts over

the rim of the pulley.

2. Adjust the motor plate until proper tension is reached.

For proper tension, a

deection of approximately

1/4” per foot of center distance should be

obtained by rmly pressing the belt. See drawing to the right.

3. Lock the motor plate adjustment nuts in place.

4. Ensure pulleys are properly aligned. See next section.

The drawing below indicates where to measure the

allowable gap for the drive alignment tolerance. All

contact points (indicated by WXYZ) are to have a gap

less than the tolerance shown in the table. When the

pulleys are not the same width, the allowable gap must

be adjusted by half of the difference in width. Figure

3 illustrates using a carpenter’s square to adjust the position of the motor pulley until the belt is parallel to the

longer leg of the square.

Installation

Insert the fan into the wall opening and secure with lag

screws, anchor bolts, or other suitable fasteners.

Always mount belt drive wall fans in order that the

motor base is below the fan shaft.

Wiring

Proper Electrical Safety Habits

Correctly label the circuit on the main power box and always identify a closed switch to promote safety

(i.e., red tape over a closed switch).

All wiring should be in accordance with local ordinances and the National Electrical Code, NFPA 70. Ensure the power supply (voltage, frequency, and current carrying capacity of wires) is in accordance with the motor nameplate. Follow the wiring diagram in the disconnect switch and the wiring diagram provided with the motor.

Leave enough slack in the wiring to allow for motor

movement when adjusting belt tension. Some fractional

motors have to be removed in order to make the

connection with the terminal box at the end of the motor.

Wall Fans

1. Extend wires to the fan.

2. Prevent excess wire from entering the shaft and

propeller area by restraining the excess wire to a

point outside the base.

Wall Fans with Wire Guard

1. Remove end panel from the wire guard to gain access to the motor.

2. Extend wires through a side panel of the wire guard to gain access to the motor.

3. Prevent excess wire from entering the shaft and

propeller area by restraining the excess wire to a

point outside the base.

Wall Fans with Wall Housing

1. Remove end guard from the wall housing.

2. Drill a hole through either side panel at a convenient location and pull the wires through. Do not pull wires through wire guard at the back panel.

3. Restrain the incoming wire at the side panel to

prevent excess wire from entering the shaft and

propeller area.

Shutters

If your fan is supplied with a shutter, follow the direction

below. If your fan is not supplied with a shutter, proceed to Final Installation Steps.

To ensure long-life, make a weather-proof seal by using

a good quality silicon caulking under the shutter ange.

1. Place the shutter into the wall opening.

2. Mount the shutter to the supporting surface using Number 12 sheet metal screws on six inch centers around the perimeter.

3. Manually operate the shutter to ensure the blades move freely.

Typical Installation

Refer to page 8.

Final Installation Steps

1. Inspect fasteners and setscrews, particularly fan mounting and bearing fasteners, and tighten according to the recommended torque shown in

the table on page 4, Recommended Torque for Setscrews/Bolts.

2. Inspect for correct voltage with voltmeter.

3. Ensure all accessories are installed.

4. Test the fan to be sure the rotation is the same as indicated by the arrow marked Rotation.

Proper Rotation

Do not allow the fan to run in the wrong direction. This will overheat the motor and cause serious damage. For 3-phase motors, if the fan is running in the wrong direction, check the control switch. It is

possible to interchange two leads at this location so

that the fan is operating in the correct direction.

Operation

Pre-Start Checks

1. Lock out all the primary and secondary power sources.

2. nspect fasteners and setscrews, particularly

those used for mounting the unit, and tighten if

necessary.

3. Inspect belt tension and pulley alignment.

(Remember, if belt tension is correct, a loud squeal

occurs as the fan increases to full power.)

4. Inspect motor wiring.

5. Ensure the belt touches only the pulleys.

6. Rotate the prop to ensure it does not rub against the venturi.

7. Ensure fan and ductwork are clean and free of debris.

8. Test the fan to ensure the rotation of the propeller is the same as indicated by the rotation label.

9. Close and secure all access doors.

10. Restore power to unit.

Start Up

Turn the fan on. In variable speed units, set the fan to

its lowest speed. Inspect for the following:

• Direction of rotation.

• Excessive vibration.

• Unusual noise.

• Bearing noise.

• Improper belt alignment or tension (listen for a continuous squealing noise).

• Improper motor amperage or voltage.

NOTICE! If a problem is discovered, immediately shut off the fan. Lock out all electrical power and check for the cause of the trouble. Refer to Troubleshooting

Inspection

Inspection of the fan should be conducted at the rst

30 minute, 8 hour and 24 hour intervals of satisfactory

operation. During the inspections, stop the fan and inspect as per directions below.

30 Minute Interval

Inspect bolts, setscrews, and motor mounting bolts.

Adjust and tighten as necessary.

8 Hour Interval

Inspect belt alignment and tension. Adjust and tighten

as necessary.

24 Hour Interval

Inspect belt tension. Adjust and tighten as necessary.

Maintenance

Establish a schedule for inspecting all parts of the fan. The frequency of inspection depends on the operating conditions and location of the fan.

Inspect fans exhausting corrosive or contaminated

air within the rst month of operation. Fans exhausting

contaminated air (airborne abrasives) should be

inspected every three months. Clean the propeller and air inlets if material build-up is excessive. Excessive build-up can cause imbalance and failure of the propeller. Regular

inspections are recommended for fans exhausting

non-contaminated air. It is recommended the following inspections be conducted twice per year.

• Inspect bolts and setscrews for tightness. Tighten as

necessary.

• Inspect belt wear and alignment. Replace worn belts with new belts and adjust alignment as needed. See Belt and Pulley Installation, on page 2.

• Bearings should be inspected as recommended in the Conditions Chart, below.

• Inspect for cleanliness. Clean exterior surfaces only.

Removing dust and grease on motor housing assures

proper motor cooling.

Lubricants

Loren Cook Company uses petroleum lubricant in a

lithium base conforming to NLGI grade 2 consistency.

Other grades of grease should not be used unless the

bearings and lines have been ushed clean. If another grade of grease is used, it should be lithium-based.

A NLGI grade 2 grease is a light viscosity, low-

torque, rust-inhibiting lubricant that is water resistant. Its

temperature range is from -30°F to +200°F and capable of

intermittent highs of +250°F.

Motor Bearings

Motors are provided with prelubricated bearings. Any

lubrication instructions shown on the motor nameplate

supersede instructions below.

Direct Drive 1050/1075,1200,1300 &1500 rpm units use

a prelubricated sleeve bearing that has a oil saturated

wicking material surrounding it. The initial factory

lubrication is adequate for up to 10 years of operation

under normal conditions. However, it is advisable to add lubricant after 3 years. Use only LIGHT grade mineral oil or SAE 10W oil up to 30 drops. If the unit has been stored

for a year or more it is advisable to lubricate as directed

above. For units in severe conditions, lubrication intervals should be reduced to half.

Motors without sleeve bearings (as described above)

will have grease lubricated ball or roller bearings. Motor

bearings without provisions for relubrication will operate up

to 10 years under normal conditions with no maintenance.

In severe applications, high temperatures or excessive contaminates, it is advisable to have the maintenance department disassemble and lubricate the bearings after 3

years of operation to prevent interruption of service.

For motors with provisions for relubrication, follow

intervals of the table below.

Fan Bearings

The fan bearings are provided prelubricated. Any

specialized lubrication instructions on fan labels

supersedes information provided herein. Bearing grease

is a petroleum lubricant in a lithium base conforming to a

NLGI #2 consistency. If user desires to utilize another type of lubricant, they take responsibility for ushing bearings

and lines, and maintaining a lubricant that is compatible

with the installation.

A NLGI #2 grease is a light viscosity, low-torque, rust-

inhibiting lubricant that is water resistant. Its temperature

range is from -30°F to 200°F and capable of intermittent

highs of 250°F.

Bearings should be relubricated in accordance with the

condition chart below.

For best results, lubricate the bearing while the fan is in

operation. Pump grease in slowly until a slight bead forms around the bearing seals. Excessive grease can damage

seal and reduce life through excess contamination and/or

loss of lubricant.

In the event that the bearing cannot be seen, use no

more than three injections with a hand operated grease

gun.

Motor Services

Should the motor prove defective within a one-year period, contact your local Loren Cook representative or your nearest authorized electric motor service

representative.

Changing Shaft Speed

All belt driven Propeller Wall fans with motors up to and

including 5HP are equipped with variable pitch pulleys. To change the fan speed, perform the following:

a. Loosen setscrew on driver (motor) pulley and remove key, if equipped.

b. Turn the pulley rim to open or close the groove facing.

If the pulley has multiple grooves, all must be adjusted to

the same width.

c. After adjustment, inspect for proper belt tension.

Speed Reduction

Open the pulley in order that the belt rides deeper in the

groove (smaller pitch diameter).

Speed Increase

Close the pulley in order that the belt rides higher in the

groove (larger pitch diameter). Ensure that the RPM limits

of the fan and the horsepower limits of the motor are

maintained.

Pulley and Belt Replacement

1. Clean the motor and fan shafts.

2. Loosen the motor plate mounting bolts to relieve the belt tension. Remove the belt.

3. Loosen the pulley setscrews and remove the pulleys from the shaft. NOTICE! If excessive force

is required to remove the pulleys, a threejaw puller can be used. This tool, however, can easily warp a pulley. If the puller is used, inspect the trueness of the pulley after it is removed from the shaft. The pulley will need replacement if it is more than 0.020 inch out of true.

4. Clean the bores of the pulleys and place a light coat of oil on the bores.

5. Remove grease, rust and burrs from the shaft.

6. Place fan pulley on the fan shaft and the motor pulley on the motor shaft. Damage to the pulleys

can occur when excessive force is used in placing

the pulleys on their respective shafts.

7. After the pulleys have been correctly placed back onto their shafts, tighten the pulley setscrews.

8. Install the belts on the pulleys. Align and adjust the

belts to the proper tension as described in Belt and Pulley Installation, page 2

Bearing Replacement

The fan bearings are pillow block ball bearings.

1. Mark the position of the shaft in reference to both the bearing races and the propeller and pulley.

Make a note of the clearance between the propeller

and the frame.

2. Remove the pulley.

3. Remove the propeller from the shaft. A two-jaw

puller may be needed to remove the propeller from

the shaft.

4. Remove the bearing hold-down bolts. Remove the shaft and the bearings as one unit.

5. Remove the anti-corrosion coating from the shaft with a suitable degreaser.

6. Remove the bearing from the shaft using a bearing puller. If a bearing puller is not available, remove the bearing by using a wood block and hammer. An emery cloth or le may be needed to remove imperfections in the shaft left by the setscrews.

7. Clean the shaft and bearing bore thoroughly.

8. Place the bearings into position ensuring they are not on a worn section of the shaft. Tapping the

inner ring face with a soft driver may be required. Do not hammer on the housing.

9. The outer ring of the bearing is spherical and

swivels in the housing to compensate for

misalignment. Slightly tighten the hold down bolts.

10. Align the setscrews on the bearings and tighten one setscrew on each bearing.

11. Rotate the shaft to allow the bearing outer rings to nd the center of free movement.

12. Install the propeller on the shaft and adjust the

bearing position to center the propeller in the

opening.

13. Tighten the hold-down bolts to the proper torque. Refer to the Torque Chart, page 4.

14. Turn the shaft by hand. Resistance should be the

same as it was before the hold-down bolts were fully

tightened.

15. Tighten the bearing setscrews to the specied torque.

16. Install the pulley and adjust the belt tension.

17. After 24 hours of continuous operation, tighten the setscrews to the appropriate torque. This assures the full locking of the inner race to the shaft. Ensure

the socket key or driver is in good condition with no

rounded corners. The key should be fully engaged

in the setscrew and held squarely to prevent the rounding out of the setscrew socket when applying

maximum torque.

18. Tighten the bearing setscrews to the specied torque.

19. Install the pulley and adjust the belt tension.

20. After 24 hours of continuous operation, tighten the setscrews to the appropriate torque. This assures the full locking of the inner race to the shaft. Ensure

the socket key or driver is in good condition with no

rounded corners. The key should be fully engaged

in the setscrew and held squarely to prevent the rounding out of the setscrew socket when applying

maximum torque.

Exhaust package fan with shutter guard

Illustrated is the typical installation of an exhaust PAC-

Fan in a masonry wall with a shutter guard. The installer

provides suitable fasteners (Hex bolts or Lag screws) to

support the fan. It is recommended that 5/16” minimum
