RECEIVING AND INSPECTION
Immediately upon receipt of a shipment, carefully inspect for damage and shortage. Turn the impeller by hand to see that it turns freely and does not bind. If any damage and/or shortage is detected or suspected, the carrier must be asked to conduct an inspection. The consignee's representative should not accept a shipment without a notation on the delivery receipt indicating items not delivered or the apparent extent of damage.
When a shipment is opened and damage is found which was not evident externally (concealed damage), it is mandatory that the consignee request an immediate inspection by the carrier. Report any damage to the carrier within 15 days. Failure to report damage within the above time limit will result in rejection of a claim.
HANDLING
CAUTION! This fan has rotating parts and safety precautions
must be exercised during its handling, installation, operation and maintenance.
When handling fans and their accessories, always use equipment and methods that will not cause damage. Fans should be lifted using slings and padding or spreaders to avoid damage.
Make sure that all lifting and handling equipment and techniques conform to current safety standards.
Avoid lifting fans in a way that will bend or distort fan parts. Never pass slings or timbers through the orifices of fan.
Fans with special coatings or paints must be protected in handling to prevent damage.
STORAGE
Fans are protected against damage during shipment. If they cannot be installed and put into operation immediately upon receipt certain precautions are necessary to prevent deterioration during storage. Responsibility for integrity of fans and accessories during storage must be assumed by the user. The manufacturer will not be responsible for damage during storage. These suggestions are provided solely as a convenience to the user, who shall make his own decision as to whether to use any or all of them.
Thermostatically controlled portable heaters (vented to outdoors) may be required to maintain even temperatures inside the enclosure.
CAUTION! Provide fire extinguishers, or fire alarms, or emergency response communication to protect building and equipment against fire damage. Be sure that building and storage practices meet all local, state and federal fire and safety codes.
The following fans or accessories must be stored indoors, in a clean dry atmosphere:
a. Propeller wall fans not in wall housings. b. Any fan that is protected by a cardboard carton. c. Motors dismounted from fans. d. Spare wheels or propellers. e. Belts, sheaves, bushings and other parts when not
mounted on fan. f. Boxes, bags or cartons of hardware. g. Curbs h. Dampers
Remove any accumulations of dirt, water, ice or snow and wipe dry before moving indoor storage. Allow cold parts to reach room temperature to avoid “sweating” of metal parts. Open boxes or cartons. Remove any accumulated moisture; if necessary use portable electric heaters to dry parts and packages. Leave coverings loose to permit air circulation and to permit periodic inspection.
Rotate wheels or propellers by hand to distribute bearing grease over the entire bearing surfaces.
Store at least 3 ½” off the floor on wooden blocks covered with moisture proof paper or polyethylene sheathing. Provide aisles between parts and along all walls, to permit air circulation and space for inspection.
OUTDOOR: Fans designed for outdoor use may be stored outdoors, if absolutely necessary. The storage area should be reasonably level and drained or ditched to prevent accumulation of water. Fencing and lighting for security are desirable. Roads or aisles for portable cranes and hauling equipment are needed. Consider the use of drift fencing to minimize accumulation of blowing snow or dirt.
INDOOR: The ideal storage environment for 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 at between 70°F and 105°F (wide temperature swings may cause condensation and "sweating" of metal parts). Windows should be covered to prevent temperature variations caused by sunlight. Provide thermometers and humidity indicators at several points and maintain the atmosphere at 40% relative humidity, or lower.
It may be necessary to use trays of renewable desiccant or portable dehumidifier to remove moisture from the air in the storage enclosure.
The following fans may be stored outdoors, if dry indoor storage space is not available:
a. Fans intended for outdoor use that are crated in wood. b. Wall fans installed in wall housings.
All fans must be supported on wooden blocks or timbers above water or normal snow levels. Provide enough blocking to prevent settling into soft ground. Fans should be set in place using the directional arrow markings on the crate as a guide.
Locate pieces far enough apart to permit air circulation, sunlight, and space for periodic inspection. Place all parts on their supports so that rain water will run off, or to minimize water accumulation. Do not cover parts with plastic film or tarps-these cause condensation of moisture from the air passing through heating and cooling cycles.
Fan wheels and propellers should be blocked to prevent spinning caused by strong winds.
INSPECTION AND MAINTENANCE
DURING STORAGE
Inspect fans and accessories at least once per month, while in storage. Log results of inspection and maintenance performed. A typical log entry should include the following:
a. Date b. Inspector’s Name c. Name of Fan d. Location e. Condition of Paint or Coating f. Is moisture present? g. Is dirt accumulated? h. Corrective steps taken?
If moisture or dirt accumulations are found on parts, the source should be located and eliminated. Fans should be rotated at each inspection by hand ten to fifteen revolutions to redistribute the motor and bearing lubricant.
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.
loosen bolts holding bearings to fan frame. This will allow centering of shaft and impeller in the fan housing. To move the shaft in the bearings, remove bolts and top half of bearing shell, then loosen set screws on the bearings, and slide the shaft through the bearings.
If fan is equipped with pillow block bearings, loosen the set screws holding bearings to shaft and slide the shaft through the bearings. Tighten all set screws. (See Maintenance section for bearing replacement).
5. If motor is not factory mounted, set motor on fan motor base so that the shaft extends over the belt tube and fan shaft. To attach motor to base use four bolts and nuts which match holes in base. Before tightening, slide the motor toward the belt tube to take out all slack in the bolts. This insures the motor shaft is square with the fan. Tighten the motor bolts.
6. Slide the motor pulley onto the motor shaft and insert the square key into the keyway. Leave the pulley loose. Put the belt(s) over the fan and motor sheaves.
In some cases, it may be helpful to remove the bearing cover for access to the fan sheave. Align the belts and set belt tension. Motor base jack screws and locknuts are provided with each fan. They should be screwed into the weld nuts on the motor base to set belt tension.
Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur. The most critical items are pulleys, shafts and bearing locking collars. At the first sign of rusting on any of the above parts, remove the original rust preventive coating with petroleum solvent and clean lint-free cloths. Polish any remaining rust from surfaces with crocus cloth or fine emery paper and oil. Do not destroy the continuity of the surfaces. Wipe clean with lint-free cloths and recoat surfaces evenly and thoroughly with Tectly 506 (Ashland Oil Company) or equal. For hard to reach internal surfaces or for occasional use, consider using Tectly 511M Rust Preventive or WD40 or equal.
REMOVING FROM STORAGE
As fans are removed from storage to be installed in their final location, they should be protected and maintained in similar fashion, until the fan equipment goes into operation.
INSTALLATION
1. These fans can be operated only if the exhausted air and the surrounding environment are always free of flammable gases, vapors, or liquids, combustible dusts or ignitable fibers or flyings. The fans cannot be used
in hazardous environments where the fans electrical system could provide ignition to combustible or flammable materials. The installation of the product
must comply with all local and national safety codes including the National Electrical Code (NEC) and the National Fire Protection Act (NFPA).
2.
WARNING! If gases, other than clean air, are to be exhausted using the fan, then the user bears the responsibility of determining that the fan is appropriate and safe for the application.
3. Remove fan from package and inspect within 15 days after receipt. If damaged, report damage to carrier. Motor and drives (motor pulley and belts) may be shipped separate from the fan.
4. Before installing, check all fasteners for tightness; particularly the propeller and shaft for torque requirements see table on page 4.
Turn the impeller by hand to make sure it does not strike the orifice. If it does hit, remove bearing cover and
The belt should depress its width when pressed firmly inward at midpoint between the pulleys.
Tighten set screw on motor pulley. For torque requirements see table on page 4.
7. Securely support unit and attach duct work. Attach any options at this point.
8.
WARNING! Before proceeding, make sure electrical service to fan is locked in “OFF” position.
9. All wiring should be in accordance with local ordinances and the National Electrical Code.
10. 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. WARNING! Electrical connections that do not exactly match the motor nameplate may cause fire.
Leave enough slack in the wiring to allow for vertical movement of the motor as necessary.
11.
WARNING! Unguarded rotating parts will be exposed during this procedure. Operate under power and compare impeller rotation with directional arrow on the fan.
Operation in reverse direction (opposite the rotation arrow marked on the fan) will deliver reduced air but will overload the motor.
In the case of three phase motors, the rotation can be reversed by interchanging any two (2) of the three (3) motor leads.
In the case of single phase motors, the reversing instructions will appear on the wiring diagram in the motor wiring compartment if reversing is possible.
12.
WARNING! Inlet, discharge and drive guards must be installed when fan is within reach of personnel or within eight (8) feet (2.5 m) of working level or when deemed advisable for safety.
