RECEIVING & START-UP Receiving Inspection When unit is received, inspect immediately for damaged or missing parts. Even though all units are carefully inspected and prepared for shipment at the factory, rough handling enroute may cause concealed damage or cause nuts, bolts or locking collars to work loose. Check propeller to see that it rotates freely and that there are no obstructions. Be certain all bolts and locking collars are tightened securely.

OPERATION Before Start-Up 1. Inspect all fasteners to make sure they are secure. A. Foundation bolts B. Set screws in fan wheel and V-Belt drive C. Housing, bearing and motor mounting bolts 2. Access Doors should be tight and sealed. 3. Bearings should be checked for alignment and lubrication. 4. Turn rotating assembly by hand to insure that it does not strike housing. If the wheel strikes the housing, the wheel may have sustained damage, moved on the shaft, or the bearings may have shifted in transit.

GENERAL MAINTENANCE CAUTION: Before any maintenance or service is performed, be sure that unit is disconnected from power source to prevent accidental starting. Periodic inspection of all the fan parts is the key to good maintenance and trouble free fan operation. Frequency of inspection must be determined by the user and is dependent upon the severity of the application. NEVER SERVICE OR ADJUST ROTATING EQUIPMENT WHILE IT IS OPERATION. LOCK OUT THE POWER SOURCE BEFORE PERFORMING MAINTENANCE.

Fan shipped completely assembled have had V-belt drive aligned at the factory. Alignment should be re-checked before operation as a precaution due to handling during shipment. 1. Be sure sheaves are locked in position. 2. Key should be seated firmly in keyway. 3. Place straight edge or taut cord across faces of driving and driven sheaves to check alignment. The motor and fan shafts must be parallel with V-belts and at right angles to the shafts. 4. Start the fan. Check for proper rotation.

BEARING MAINTENANCE D. SEALED BEARINGS: Sealed for life bearings are pre-lubricated with the correct amount of manufacturer-approved ball bearing grease, and are designed for application where relubrication is not required. Units feature two single row deep groove bearings in rugged cast aluminum or cast iron bearing bracket. Dirt and grease guard seals are an integral part of the assembly. For high temperature applications, the bearings are pre-lubricated with high temperature greases.
PAGE 7
For most applications, a lithium base grease conforming to a NLGI grade 2 consistency should be used. This type of grease inhibits rust, is water resistant, and has a temperature range of -30°F to 200°F with intermittent highs of 250°F. When greasing bearings it is important not to overgrease. This is especially true if the bearings are equipped with extended grease lines and the bearings are not visible. In this case more bearing failures occur due to overgreasing than undergreasing.

ORDERING REPLACEMENT PARTS The following information should accompany part orders: 1. Motor horsepower, frame size, and motor speed. If motor is to be replaced, furnish voltage, phase, cycle, and enclosure and model number from motor nameplate. 2. Fan speed (if V-belt driven) 3. Serial numbers, model numbers and complete description of the part.
