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
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.
CAUTION! Always 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 fan orifice.
CAUTION! Do not lift by the fan hood. Fans with special coatings or paints must be protected in handling to prevent damage.
FORM 610032
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 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 to 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.
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.
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 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.
Thermostatically controlled portable heaters (vented to outdoors) may be required to maintain even temperatures inside the enclosure.
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.
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.
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. CAUTION! This unit has rotating parts and safety
precautions should be exercised during installation, operation and maintenance.
2. WARNING! DO NOT use in HAZARDOUS
ENVIRONMENTS where fan’s electrical system could provide ignition to combustible or flammable materials, unless unit is specifically built for hazardous environments.
3. MOUNTING The fan should be mounted on a solid
foundation equipped with anchoring devices (such as anchor bolts). Level the fan on the foundation, shimming where necessary. Anchor the fan securely to the foundation. If vibration isolators are used, these should be installed between the fan and the foundation. When mounted on suspended platforms, adequate cross bracing will be required. Flexible connections at the inlet and/or outlet are recommended.
5. CAUTION! Before proceeding, make sure electrical
service to fan is locked in “OFF” position. All wiring should be in accordance with local ordinances and the National Electric Code.
(a) Check voltage at the fan to assure it corresponds
with motor nameplate; high or low voltage can seriously damage the motor. Extra care should be taken when wiring two speed motors to assure proper motor lead groupings are used since improper connections WILL damage motors and void motor warranty.
(b) Apply power momentarily to check impeller rotation
with directional arrow. In the case of three phase motors, the direction can be reversed by interchanging any two of the three motor leads. For single phase motors, the reversing instructions appear on the wiring diagram located on the motor. WARNING! Operation in the wrong direction will deliver a reduced amount of air.
6. OUTDOORS FCF units are provided with standard
Weather Covers (Arr. 10). Outlet shutters attached to the fan discharge should be normally closed when the fan is not running.
7. BELT GUARDS (Weather covers also serve as belt
guards) must be installed when fan is within reach of personnel or located within 7 feet (2.134 m) of working level or when deemed advisable for safety.
8. INLET, OUTLET GUARDS (Available from Acme as
optional equipment) must be installed whenever the fan is installed without ducts attached to the fan inlet and/or outlet and is within seven (7) feet (2.134 m) of working level or when deemed advisable for safety.
9. DISCHARGE POSITION ROTATION - FCF SERIES
(ARR. 10) Remove motor enclosure cabinet cover and lay unit down on intake collar. (Figure 2)
Remove 8 bolts and rotate motor compartment to desired position (Figure 3) and replace 8 bolts in new
position. FCF housing is rotatable in 45° increments. The FCA and FCE housing is rotatable in 90°
increments by changing the location of the feet.
4. BELT DRIVES Check pulley alignment and belt
tension. Belt should deflect .50" (13 mm) to .75" (19 mm) when depressed by hand midway between pulleys. A belt should be just tight enough to avoid slippage. When the motor and drives are received mounted to the (FCF) fan, the RPM has been set to meet the specified performance. Motor positions for the FCD, FCH and FCJ blowers are defined in Figure 1.
For fans shipped without motors and drives mounted, the RPM is set by the installer as specified. Pulley combinations and belt lengths are included with each blower.
