Installation

Fans mounted to a wall require a different wall opening size than fans mounted in wall collars or wall housings. For specific dimensions, refer to the submittal drawing for the specific 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 field 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.

a. Remove the motor plate mounting bolts and motor

plate.

b. Remove the motor mounting bolts from the motor

plate.

c. Mount the motor to the motor plate aligning the appro-

priate holes.

d. Place the motor plate on the power assembly and

reinstall the mounting bolts.

Receiving and Inspection

Carefully inspect the fan and accessories for any da mage

and shortage immediately upon receipt of the fan.

• Turn the propeller by hand to ensure it turns freely and does not bind.

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

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 five days to keep a coating of grease on all internal bearing parts.

Personal Safety

Disconnect switches are recommended. Place the disconnect switch near the fan in order that the power can be swiftly cut off in case of an emergency, and in order that maintenance p ersonnel are provided complete control of the power source.

Belt tension is determined by the sound of the belts when the fan is first 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 efficiency and damage can occur.

Do not change the pulley pitch diameter to change tension. The change will result in a different fan speed.

a. 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.

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

For proper tension, a deflection of approximately 1/4” per foot of center distance should be obtained by firmly

pressing the belt. Refer to Figure 1. c. Lock the motor plate adjustment nuts in place. d. Ensure pulleys are properly aligned. Refer to Figure 2.

Pulley Alignment

Pulley alignment is adjusted by loosening the motor pulley setscrew and by moving the motor pulley on the motor shaft.

Figure 2 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

Figure 3

pulley until the belt is parallel to the longer leg of the square.

Fan Installation

Insert the fan into the wall opening and secure wit h 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 Installation

All wiring should be in accordance with local ordinances and the National Electrical Code, NFP A 70. Ensure the power supply (voltage, frequency, and current carrying capacity of wires) is in accordance with the motor nameplate. Refer to the Wiring Diagrams, next page.

Lock off all power sources before unit is wired to power source.

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.

Follow the wiring diagram in the disconnect switch and the wiring diagram provided with the motor. 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).

Wall Fans

a. Extend wires to the fan. b. Prevent excess wire from entering the shaft and propel-

ler area by restraining the excess wire to a point outside the base.

Wall Fans with Wire Guard

a. Remove end panel from the wire gua rd to gain access to

the motor.

b. Extend wires through a side panel of the wire guard to

gain access to the motor.

c. Prevent excess wire from entering the shaft and propel-

ler area by restraining the excess wire to a point outside the base.

Wall Fans with Wall Housing

a. Remove end guard from the wall housing. b. 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.

c. Restrain the incoming wire at the side panel to prevent

excess wire from entering the shaft and propeller area.

Shutter Installation

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 flange.

a. Place the shutter into the wall opening.

Final Installation Steps

a. 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 Set-

screws/Bolts. b. Inspect for correct voltage with voltmeter. c. Ensure all accessories are installed.

d. Test the fan to be sure the rotation is the same as

indicated by the arrow marked Rotation.

For 3 phase, damper motor voltage should be the same between L1 and L2. For single phase application, disregard L in 115, 230 and 460 volt models. The damper motor nameplate voltage should

. *Damper motors may be available

be verified prior to connection. **A transformer may be provided in some installations to correct the damper motor voltage to the specified voltage.

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 Chec ks

a. Lock out all the primary and secondary power sources. b. Inspect fasteners and setscrews, particularly those

used for mounting the unit, and tighten if necessary.

c. Inspect belt tension and pulley alignment. (Remember,

if belt tension is correct, a loud squeal occurs as the fan

increases to full power.) d. Inspect motor wiring. e. Ensure the belt touches only the pulleys. f. Rotate the prop to ensure it does not rub against the

venturi.

g. Ensure fan and ductwork are clean and free of de b ris.

same as indicated by the rotation label. i. Close and secure all access doors. j. Restore power to unit.

Start Up

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

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.

If a problem is discovered, immediately shut off the fan. Lock out all electrical power and c heck for th e cause of the trouble. Refer to Troubleshooting, page 7.

Inspection

Inspection of the fan should be conducted at the first 30 minute, 8 hour and 24 hour intervals of satisfactory opera-

tion. 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.

• 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 flushed clean. If another grade of grease is used, it should be lithium-based.

A NLGI grade 2 grease is a light viscosity, low-torque, rustinhibiting 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 bearing s. Motor b earing s 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 opera tio n to prevent interruption of service.

For motors with provisions for relubrication, follow intervals of the table below.

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 first 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.

Motors are provided with a polyurea mineral oil NGL I #2 grease. All additions to the motor bearings are to be with a compatable grease such as Exxon Mobil Polyrex EM and Chevron SRI.

The above intervals should be reduced to half for vertical

shaft installations.

Fan Bearings

The fan bearings are provided prelubricated. Any specialized lubrication instructions on fan labels supersedes information provided herein. Bearing grease is a petro leum lubricant in a lithium base conforming to a NLGI #2 consistency. If user desires to utilize another type of lubricant, they take responsibility for flushing bearings and lines, and maintaining a lubricant that is compatible with the installation.

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

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 ma in tained.

Pulley and Belt Replacement

a. Clean the motor and fan shafts. b. Loosen the motor plate mounting bolts to relieve the

belt tension. Remove the belt.

c. Loosen the pulley setscrews and remove the pulleys

from the shaft.

If excessive force is required to remove the pulleys, a three-jaw 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.

d. Clean the bores of the pulleys and place a light coat of

oil on the bores. e. Remove grease, rust and burrs from the shaft. f. 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.

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 r im 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).

g. After the pulleys have been correctly placed back onto

their shafts, tighten the pulley setscrews.

h. 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.

a. 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. b. Remove the pulley. c. Remove the propeller from the shaft. A two-jaw puller

may be needed to remove the propeller from th e shaft. d. Remove the bearing hold-down bolts. Remove the

shaft and the bearings as one unit. e. Remove the anti-corrosion coating from the shaft with

a suitable degreaser. f. 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 emer y

cloth or file may be needed to remove imperfections in

the shaft left by the setscrews. g. Clean the shaft and bearing bore thoroughly. h. 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 ham-

mer on the housing. i. The outer ring of the bearing is spherical and swivels in

the housing to compensate for misalignment. Slightly

tighten the hold down bolts. j. Align the setscrews on the bearings and tighten one

setscrew on each bearing. k. Rotate the shaft to allow the bearin g outer rings to find

the center of free movement. l. Install the propeller on the shaf t and a djust the bear ing

position to center the propeller in the opening. m. Tighten the hold-down bolts to the proper torque.

Refer to the Torque Chart, page 4. n. Turn the shaft by hand. Resistance should be the

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

tightened.

o. Tighten the be aring se tscrews to the specified torque. p. Install the pulley and adjust the belt tension.

After 24 hours of continuous operation, tighten the set-

screws 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.
