Receiving and Inspection

Carefully inspect the fan and accessories for any damage

and shortage immediately upon receipt of the fan.

• Turn the wheel by hand to ensure it turns freely and does

not bind

• Check dampers (if included) for free operation of all mov-

ing parts

• Record on the Delivery Receipt any visible sign of damage

Handling

Lift the fan by the base or the shipping carton.

NOTICE! Never lift by the shaft, motor or housing.

Storage

If the fan is stored for any length of time prior to installation,

completely ll the bearings with grease or moisture-inhibiting oil

(refer to Fan Bearing, page 4). Store the fan in its original crate

and protect it from dust, debris and weather.

• Cover the inlet, and outlet opening to prevent the accumula-

tion of dirt and moisture in the housing

• Periodically rotate the wheel and operate to keep a coating

of grease on all internal bearing parts

• Periodically inspect the unit to prevent damaging conditions

Low Prole Roof Exhausters

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Rotating Parts & Electrical Shock Hazard:

Fans should be installed and serviced by qualied personnel

only.

Disconnect electric power before working on unit (prior to re-

moval of guards or entry into access doors).

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 o󰀨, in case of an emergency

and in order that maintenance personnel are provided com-

plete control of the power source.

Grounding is required. All eld-installed wiring must be com-

pleted by qualied personnel. All eld installed wiring must

comply with National Electric Code (NFPA 70) and all appli-

cable local codes.

Fans and blowers create pressure at the discharge and vac-

uum at the inlet. This may cause objects to get pulled into the

unit and objects to be propelled rapidly from the discharge.

The discharge should always be directed in a safe direction

and inlets should not be left unguarded. Any object pulled into

the inlet will become a projectile capable of causing serious

injury or death.

When air is allowed to move through a non-powered fan, the

impeller can rotate, which is referred to as windmilling. Wind-

milling will cause hazardous conditions due to unexpected ro-

tation of components. Impellers should be blocked in position

or air passages blocked to prevent draft when working on fans.

Friction and power loss inside rotating components will cause

them to be a potential burn hazard. All components should be

approached with caution and/or allowed to cool before con-

tacting them for maintenance.

Under certain lighting conditions, rotating components may

appear stationary. Components should be veried to be sta-

tionary in a safe manner, before they come into contact with

personnel, tools or clothing.

Failure to follow these instructions could result in death or se-

rious injury.

The attachment of roof mounted fans to the roof curb as well

as the attachment of roof curbs to the building structure must

exceed the structural requirements based on the environmen-

tal loading derived from the applicable building code for the

site. The local code o󰀩cial may require variations from the

recognized code based on local data. The licensed engineer

of record will be responsible for prescribing the correct attach-

ment based on construction materials, code requirements and

environmental e󰀨ects specic to the installation.

This publication contains the installation, operation and

maintenance instructions for standard units of the LC (HLC-D,

HLC-B, TLC-D and TLC-B): Low Prole Roof Exhausters.

Carefully read this publication and any

supplemental documents prior to any

installation or maintenance procedure.

Loren Cook catalog, LC, provides additional information de-

scribing the equipment, fan performance, available accesso-

ries and specication data.

Figure 2 indicates where to measure

the allowable gap for the drive align-

ment tolerance. All contact points (in-

dicated 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 di󰀨erence in

width. Figure 3 illustrates using a car-

penter’s square to adjust the position

of the motor pulley until the belt is par-

allel to the longer leg of the square.

Wiring Installation

Leave enough slack in the wiring to allow for motor move-

ment 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.

Refer to Wiring Diagrams, next page.

NOTICE! Follow the wiring diagram in the disconnect

switch and the wiring diagram provided with the mo-

tor. 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).

Fan Installation

The fan support (roof curb) should provide a level surface

for installation. If the roof is pitched more than 1/2:12, a sloped

curb must be used to correct for the incline. Place fan over

roof opening. Secure the fan with lag screws, anchor bolts or

other suitable fasteners.

For easier installation, larger size fans may be disassembled

on the ground and transported to the roof in sections. Howev-

er, if the sections are not assembled properly, the wheel may

rub against the fan inlet causing noise.

This can be prevented by:

• Ensuring the wheel is tightly fastened on the shaft.

• Ensuring the wheel is not dropped on the shaft before the

setscrews are tightened. Should interference occur, discon-

nect the power source. Refer to Bearing Replacement, page

Final Installation Steps

1. Inspect fasteners and setscrews, particularly fan mount-

ing and bearing fasteners, and tighten according to the

recommended torque shown in the table, Recommended

Torque for Setscrews/Bolts, page 3.

2. Inspect for correct amperage and voltage with an amme-

ter and voltmeter.

3. Ensure all accessories are installed.

4. Inspect wheel-to-inlet clearance on power roof fans.

5. Test the fan to be sure the rotation is the same as indicat-

ed by the arrow marked Rotation.

NOTICE! Do not allow the fan to run in the wrong di-

rection. This will overheat the motor and cause seri-

ous 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.

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 mounting slots.

Dampers

If your fan is supplied with dampers, follow the directions

below. If your fan does not include dampers, proceed to Belt

and Pulley Installation.

1. Place the damper inside the curb. Ensure the damper will

open freely for the correct direction of airow.

2. Secure to curb at the damper shelf.

3. Drill a hole in the curb shelf for conduit (needed for mo-

tor wiring).

4. Operate the dampers manually to ensure the blades move

freely. Dampers should be released from full open posi-

tion to check for proper closing.

5. Install fan over curb with the conduit location in line with

the conduit hole in the curb.

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 e󰀩ciency and dam-

age can occur.

Do not change the pulley pitch diameter to change tension.

The change will result in a dierent fan speed.

1. Loosen the motor plate adjustment bolts 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. Refer to Figure 1.

1 foot

1/4 inch

3. Lock the motor plate adjustment bolts in place.

4. 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.

Operation

Pre-Start Checks

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

2. Inspect fasteners and setscrews, particularly those used

for mounting the fan, and tighten if necessary.

3. Inspect belt tension and pulley alignment. (Remember, if

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

creases to full power.)

4. Inspect motor wiring.

5. Ensure the belt touches only the pulleys.

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

7. Test the fan to ensure the rotation of the wheel is the same

as indicated by the rotation label.

8. Restore power to unit.

Start Up

Turn on the fan. 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 squeal-

ing noise)

• Improper motor amperage or voltage

NOTICE! If a problem is discovered, immediately shut

o 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 opera-

tion. During the inspections, stop the fan and inspect as fol-

lows.

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 wheel and air inlets if material build-up is exces-

sive. Excessive build-up can cause imbalance and failure of

the wheel.

Regular inspections are recommended for fans exhausting

non-contaminated air.

It is recommended the following inspections be con-

ducted 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,

page 2

• Bearings should be inspected as recommended in the Conditions

Chart

• Inspect for cleanliness. Clean exterior surfaces only. Removing

dust and grease on motor housing assures proper motor cooling

Fan Bearings

The fan bearings are provided prelubricated. Any special-

ized lubrication instructions on fan labels supersedes informa-

tion provided herein. Bearing grease is a petroleum lubricant

in a lithium base conforming to an NLGI #2 consistency. If

user desires to utilize another type of lubricant, they take re-

sponsibility for ushing bearings and lines and maintaining a

lubricant that is compatible with the installation.

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

hibiting 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 Re-

lubrication Intervals 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 Bearings

Motors are provided with prelubricated bearings. Any lubri-

cation instructions shown on the motor nameplate supersede

instructions below.

Direct Drive 1050/1075, 1200, 1300 and 1500 RPM units

use a prelubricated sleeve bearing that has an oil-saturated

wicking material surrounding it. The initial factory lubrication

is adequate for up to 10 years of operation under normal con-

ditions. However, it is advisable to add lubricant after three

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 direct drive

units and other 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 ap-

plications, high temperatures or excessive contaminates, it is

advisable to have the maintenance department disassemble

and lubricate the bearings after three years of operation to

prevent interruption of service.

For motors with provisions for relubrication, follow intervals

of the table below.

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 fans with motors up to and including 5HP are

equipped with variable pitch pulleys. To change the fan speed,

perform the following:

1. Loosen setscrew on driver (motor) pulley and remove key,

if equipped.

2. 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.

3. 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 belts.

3. 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 pul-

ley after it is removed from the shaft. The pulley will need re-

placement if it is more than 0.020” 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 re-

spective 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 In-

stallation, page 2.

Bearing Replacement

The fan bearings are pillow block ball bearings.

1. Loosen screws on bearing cover.

2. Push bearing cover toward the wheel. As the bearing cov-

er moves toward the wheel, it will slide down to reveal the

bearings and shaft.

3. Remove the old bearing.

4. Remove any burrs from the shaft by sanding.

5. Slide new bearings onto the shaft to the desired location

and loosely mount bearings onto the bearing support.

Bearing bolts and setscrews should be loose enough to

allow shaft positioning.

6. Correctly position the wheel and tighten the bearing bolts

securely to the bearing support.

7. Align setscrews bearing to bearing and secure tightly to

the shaft.

NOTICE! Never tighten both pairs of setscrews before

securing bearing mounting bolts. This may damage

the shaft.

8. Inspect the wheel position again. If necessary, re-adjust

by loosening the bearing bolts and setscrews and repeat

from step 5.

Wheel Replacement

1. Drill two holes approximately centered between the shaft

and the edge of the hub OD with the following dimensions:

• 1/4” diameter

• 3/8” to 1/2” deep

• 180° apart in face of hub

2. Tap 1/4” holes to 5/16” thread with the 5/16” hole tap. Do

not drill or tap any larger than recommended.

3. Screw the puller arms into the tapped holes full depth of

threads (3/8” to 1/2” approximately). Align center of pull-

er with center of shaft. Make certain all setscrews in hub

(normally a quantity of two) are fully removed. Work puller

slowly to back wheel o󰀨 the shaft.

Recommended Puller

Lisle No. 45000 Steering Wheel Puller. This puller is avail-

able at most automotive parts retail outlets.

Wheel PullerDrilled Hole Location

Wheel-to-Inlet Clearance

The correct wheel-to-inlet clearance is critical to proper fan

performance. This clearance should be veried before initial

start-up since rough handling during shipment could cause a

shift in fan components. Refer to wheel/inlet drawing below for

correct overlap.

Adjust the overlap by loosening the wheel hub and moving

the wheel along the shaft to obtain the correct value.
