General Safety Information

Only qualiﬁ ed 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 high winds or 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 propeller 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 propeller faster than max cataloged fan RPM. Adjustments to fan speed signiﬁ cantly affects 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.

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 notiﬁ cation 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. Conﬁ rmation of shipment(s) must be limited to only items on the bill of lading.

Handling

Fans are to be rigged and moved by the optional lifting brackets provided or by the skid when a forklift is used. Location of brackets varies by model and size. Handle in such a manner as to keep from scratching or chipping the ﬁ nish. Damaged ﬁ nish may reduce the ability of the fan to resist corrosion.

Fans should never be lifted by the shaft, fan housing, motor, belt guard or accessories.

Hooded Propeller2

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 build up. 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 ﬂ oor 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 ﬁ lm or tarps as these cause condensation of moisture from the air passing through heating and cooling cycles.

Fan propellers should be blocked to prevent spinning caused by strong winds.

Inspection and 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 prop by hand ten to ﬁ fteen revolutions to distribute lubricant in motor and bearings. 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 ﬁ ne 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 ﬁ nal location, they should be protected and maintained in a similar fashion until the fan equipment goes into operation.

On fan sizes 18 to 48:

• Remove two fasteners shown in Figure 6.

• Carefully swing the hood 180° and let it rest on the roof. If desired, the entire hood may be removed by removing the two additional fasteners on the opposite side of the fan.

Use caution when handling the hood in strong winds.

On fan sizes 36 to 72 access to the motor compartment can also be made by either:

• Removing birdscreen or ﬁ lters and standing under the hood of large fans.

• Removing one interlocking hood end section of smaller units.

Electrical Connections

Before electrical connections are made, the supply voltage, phase and ampere capacity must be checked for compatibility with the fan motor. In addition, the supply wiring must be properly fused and conform to local and national electrical codes.

Figure 6

Fasteners

If the electrical supply is to be routed to the fan from the interior of the building, it should pass through the conduit hole in the fan panel. The supply wires are then connected to an optional safety disconnect switch (if supplied) or wired directly to the motor.

For three-phase installation, fan rotation can be reversed by simply interchanging any two of the three electrical leads. For single phase installations, follow the wiring diagram located on the motor.

Routine Maintenance

DANGER

Disconnect and secure to the “off” position all electrical power to the fan prior to inspection or servicing. Failure to comply with this safety precaution could result in serious injury or death.

For Belt Drive Fans

The adjustable motor pulley is preset at the factory for the speciﬁ ed fan RPM. Fan speed can be increased by closing or decreased by opening the adjustable pulley. Two or three groove variable pitch pulleys must be adjusted an equal number of turns open. Any increase in fan speed represents a substantial increase in horsepower required from the motor. Always check motor load amperage and compare to nameplate rating when changing fan speed.

Check belt tension two times during the ﬁ rst 24 hours of operation and periodically thereafter. To adjust belt tension, simply loosen four fasteners (two on each side of the motor plate) and slide the motor plate away from the fan shaft until proper belt tension is attained. On some fans, fasteners attaching the motor to the motor plate must be loosened in order to adjust the belt.

It is very important that the drive pulleys remain in proper alignment after adjustments are made. Misalignment of pulleys will result in premature belt wear, noise, vibration and power loss. See Figure 9.

Once the fan has been put into operation, a periodic maintenance program should be set up to preserve the reliability and performance of the fan. Items to be included in this program are:

Belts

Premature belt failures are frequently caused by improper belt tension (either too tight or too loose) or misaligned pulleys. The proper tension for operating a V-belt is the lowest tension at which the belts will not slip at peak load conditions. For initial tensioning, the proper belt deﬂ ection half way between pulley centers is 1/64 inch for each inch of belt span. For example, if the belt span is 64 inches, the belt deﬂ ection should be one inch using moderate thumb pressure at midpoint of the drive (Figure 8).

Bearings (Belt Drive Fans Only)

Bearings are the most critical moving part of the fan and should be inspected at periodic intervals. Locking collars and set screws, in addition to fasteners attaching the bearings to the bearing plate, must be checked for tightness. In a clean environment and temperatures above 32ºF/below 200ºF, fan shaft bearings with grease ﬁ ttings should be lubricated semi-annually using a high quality lithium based grease. If unusual environmental conditions exist temperatures below 32ºF/above 200ºF, moisture or contaminants, more frequent lubrication is required.

With the unit running, add grease very slowly with a manual grease gun until a slight bead of grease forms at the seal. Be careful not to unseat the seal by over lubricating or using excessive pressure. Bearings without grease ﬁ ttings are lubricated for life.

Fasteners and Set Screws

Any fan vibration has a tendency to loosen mechanical fasteners. A periodic inspection should include checking all fasteners and set screws for tightness. Particular attention should be paid to set screws attaching the propeller to the shaft and the shaft to the bearings. Loose bearing set screws will lead to premature failure of the fan shaft.

Lubrication

Refer to the paragraph on bearings for bearing lubrication. Many fractional horsepower motors installed on the smaller fans are lubricated for life and require no further attention. Motors equipped with oil holes should be oiled in accordance with the manufacturer’s instructions printed on the motor. Use a high grade SAE 20 machine oil and use caution not to over lubricate. Motors supplied with grease ﬁ ttings should be greased according to directions printed on the motor.

Removal of Dust and Dirt

Dirt clogs cooling openings on the motor housing, contaminates bearing lubricant and collects on propeller blades causing severe imbalance if left unchecked. The exterior surface of the motor, fan panel and entire propeller should be thoroughly cleaned periodically. Use caution and do not allow water or solvents to enter the motor or bearings. Under no circumstances should motors or bearings be sprayed with steam or water.

Filter Maintenance (Filtered Supply Fans)

Aluminum mesh ﬁ lters should be cleaned on a regular basis for optimum fan efﬁ ciency. The frequency of cleaning depends upon the cleanliness of the incoming air.

To remove ﬁ lters on fan sizes 24 to 30, ﬁ rst remove the hood as described in Access to the Motor Compartment section. The ﬁ lters can then be pulled from the slide-out racks. See Figure 10. On fan sizes 36 to 72, access panels on the end panels are provided which allow the ﬁ lters to be removed without removing the hood.

Filters should be washed with a mild detergent in warm water. After the ﬁ lters are dry, an adhesive spray available at most ﬁ lter distributors may be applied to increase ﬁ lter efﬁ ciency.

Damper Inspection and Service

If an optional tall base with damper is supplied, access to the optional damper(s) and actuator(s) is provided by a removable door. Simply release the two cam latches and slide the damper out for inspection, cleaning or service.

For fan sizes 24 through 36 supplied without a tall base, the entire unit must be lifted off the roof curb for access to the damper.

For fan sizes 42 through 72 supplied without a tall base, access to the damper is made by removing one end of the birdscreen or ﬁ lters and working on the damper from above.

Refer to WARNING at the beginning of the Routine

Maintenance section.
