Rotating PARTS including shaft and V-belt drives mustbe properly guarded to prevent personal Electrical wiring must be accomplished by a qualifiedelectrician in accordance with all applicable Care should be taken: Not to run fan above its safe speed (See Performance Tables in Sales Catalog or call CFsales office). Not to operate in excessive temperatures (See limitations in Sales Catalog or call CFsales office).

3 Not to operate in dangerous environments. Read all INSTRUCTIONS Inspection When unit is received, inspect immediately for damagedor missing PARTS . Even though all units are carefullyinspected and prepared for shipment at the factory, roughhandling en route may cause concealed damage orcause nuts, set screws, bolts or locking collars to workloose. Be certain all fasteners are tightened wheel by hand to verify that it rotates freely andthat there are no all shipments carefully for receivermust note any damage on the carrier s bill of ladingand file a claim immediately with the freight companyin case of a record of all equipmentreceived, including inspection details and date of receiptbecause of the possibility of partial SAFETY NOTESII.

Assure that the inboard bearing locking deviceis tightened to the specifications shown below in Table#2. Loosen the drive end bearing set screws, rotatethe shaft several revolutions by hand and then replaceand tighten those set screws to the specificationshown below in Table # Connecting Power all fasteners and retighten if necessary:a.

5 Foundation Set screws in wheel/prop and V-belt drive(See Tables # 1 and # 2 below).c. Bearing and motor Any inspection doors should be tight and Bearings should be checked for alignment andlubrication (See Bearing MAINTENANCE , page 4).4. Turn rotating assembly by hand to insure that it doesnot strike housing. If the wheel/prop strikes thehousing, the wheel/prop may have moved on the shaftor the bearings may have shifted in transit. Correctionmustbe made prior to start Check motor to insure proper speed and Check V-belt drive for alignment and correct After wiring, energize motor for 1 second to check forproper fan will not be put into operation within 30days, obtain long-term storage INSTRUCTIONS fromour website ( ) or your localCincinnati Fan Sales :If wheel set screws are loosened and/or wheel/prop is removed from shaft, set screws mustbereplaced.

Some fans areprovided with lifting lugs or holes for easy must be handled using nylon straps or well-padded chains and cables which protect the fan scoating and housing. Spreader bars should be usedwhen lifting large PanelThe fan panel should be mounted on a flat, rigid andsubstantial support, foundation or plenum chamberwall.

7 If the fan support is not adequate it may benecessary to field balance the complete Bell (CPF & CPAF Models Only)The inlet bell must be field mounted to thedimensional tolerances shown on the drawing onpage 6. In high temperature applications, makeallowances for expansion and contraction. The bell-to-wheel overlap should be correct at the InsulationPlug fans OPERATING in temperatures above 300 have an insulation plug section. This insulationcan be furnished by CFor can be added by the buyeror end the safe OPERATING speed for each specific unitand installation. These may vary because INSTALLATION INSTRUCTIONSV. OPERATIONThe key to good fan MAINTENANCE is a regular andsystematic inspection of all fan PARTS .

8 Severity of theapplication should determine frequency of components requiring service are generally themoving PARTS which include bearings, wheel/prop, belts,sheaves and MAINTENANCE or lock out power to Removing dust and dirt: Blow out open type motorwindings with low pressure air to remove dust or pressure above 50 should not be used ashigh pressure may damage insulation and blow dirtunder loosened tape. Dust accumulation can causeexcessive insulation Lubrication: The motor bearings and the fan bearingson the belt drive fans should be greased at regularintervals. Motor manufacturers greasing instructionsand recommendations should be followed the use of a pressure greasing system whichtends to fill the bearing chamber completely.

9 Do notovergrease. Use only 1 or 2 shots with a hand gun inmost cases. Maximum hand gun rating 40 bearings during lubrication where good safetypractice permits. NOTE: On motors with non-regreasable sealed bearings, no lubrication isrequired for the life of the bearings. Also, see bearingmaintenance on page prevent rusting of bearing PARTS , the motor shaft mustbe rotated at regular intervals (30 days) to assure theseparts are well covered with oil or should be taken not to overtighten V-beltdrive. Excessive belt tension overloads fan andmotor bearings. It is much less expensive toreplace belts worn from slippage than toreplace bearings damaged from shipped completely assembled have had V-beltdrive aligned at the factory.

10 Alignment should berechecked before operation as a precaution due tohandling during Be sure sheaves are locked in Key should be seated firmly in Place straight edge or taut cord across faces ofdriving and driven sheaves to check alignment. Themotor and fan shafts must be parallel and V-beltsmust be at right angles to the Start the fan. Check for proper rotation. Run fan at fullspeed. A slight bow should appear on slack side ofbelt. Disconnect power and adjust belt tension byadjusting motor base. All belts must have some slackon one If belts squeal at start up, they may be too When belts have had time to seat in the sheavegrooves, then readjust belt tension (2-3 days).
