Should further Information be desiredor should particular problems arise which are not covered sufficiently for the purchaser s purposes, the matter should bereferred to the General Electric Company. Copyright 1996, 1999 General Electric CompanyGEI-1003273 Vertical Motor data Information AND STORAGEThe Motor should be stored in a dry areawith factory packaging intact, unless ap-pearance of package indicates possibilityof Motor damage during shipment. Motorrating and identification data are furnishedon label for checking prior to actual use, unpack Motor androtate shaft by hand to see that it turnsfreely. (Pertains to Vertical solid shaftmotors only).

2 Remove rust preventativepaper or slushing compound from : SEE SPECIAL PROCEDURESFOR OIL LUBRICATED BEARINGS THRUST the Motor in a place that isclean and well ventilated. The motorenclosure is such that dripping, windblown, and splashing water will notdamage the Motor . Under conditionsof extreme weather and moisture,additional protection, such as apump house is recommended; how-ever, the free flow of air around themotor must not be obstructed. Theambient air temperature should notexceed 40 C or 104 F, unless themotor has been specially designed orotherwise cleared for use in a higherambient the Motor to the pump head orrigid foundation using bolts of thelargest size permitted by the holes inthe Motor alignment between motorand pump is of extreme will result in Hollow ShaftMotors (VHS)When mounting VHS motors,remove the hood and cou-pling.

3 Lower the Motor ontothe pump head with the pumpshaft extending through thehollow shaft. The motorbracket should bolt homesquare with the pump headand at right angles with thepump head shaft. The pumphead shaft should be centeredwithin the Motor hollow the coupling onto themotor and key it to the pumpshaft using the gib head on the adjusting nut sup-plied with the pump and drawup on the impellers. Lock theadjusting nut in place with ascrew through the nut into atapped hole in the ThrustThe axial thrust load im-posed upon the Motor bythe pump shaft and im-pellers plus the hydraulicload should not exceedthe value for which themotor was Ratchet Type VHSM otorsThese motors areequipped with a non-reverse ratchet that per-mits rotation in the CCWdirection (lookingdownward at the Motor )only.

4 The ratchet consistsof a stationary plate withteeth cast into it, and arotating drive hub orrunner with pins operat-ing in slots. When themotor starts in the for-ward or CCW direction,the inclined faces theratchet track lift the pinswhere they are held in bycentrifugal force. Whenthe Motor stops, the pinsmove down and preventCW or reverse rotationby locking against thevertical faces of Solid Shaft Motors(VSS)These motors are providedwith a shaft extension suitablefor coupled service, and areeither straight or tapered asselected by the : COUPLINGHALVES SHOULD HAVE ACLOSE SLIDING FIT ONTHE SHAFT EXTENSIONAND MUST BE SECURELYLOCKED TO AVOIDHAMMERING OUT INOPERATION.

5 USE A PIN ORPULLER FOR REMOVINGTIGHT ConnectionsBe sure the Motor is connected asshown on the nameplate diagram,and that the power supply (voltage,frequency, and number of phases)corresponds with the nameplatedata. Install all wiring, fusing andgrounding in accordance with Na-tional Electrical Code and local identify Motor auxiliarydevices before connecting. Thesemight be space heaters, windingthermostats, thermocouples, ther-mistors, or other temperature sen-sors. Be sure they are connectedonly in circuits for which they aredesigned and that the connectionsare carefully insulated from the mo-tor power the power supply through asuitable switch and overload change the direction of rotationon a three phase Vertical solid shaftmotor, interchange any two BoxThe conduit box may be rotated360 in 90 the Motor without load tocheck the connections and di-rection of rotation.

6 The motorwill operate satisfactorily witha 10% variation in voltage; a5% variation in frequency; or acombined voltage and fre-quency variation of 10%, butnot necessarily in accordancewith the standard of perform-ance for established operationat normal should be inspected at regu-lar intervals to check for 1) dirt, 2)moisture, 3) friction, and 4) vibra-tion, which account for 90% of allmotor Against DirtKeep the insulation and mechanicalparts of the Motor clean. Dust that isfree from oil or grease may be re-moved by wiping with a clean, drycloth, or preferably, by suction. Dustmay be blown from inaccessibleparts with clean, dry air, using notmore than 30 pounds pressure. Usecare to prevent personal injury fromthe air hoses; use goggles to avoideye injury from flying blowing Motor windings outwith air, make sure the air line is freeof condensation and grease or oil is present, wipewith a cloth moistened (but notdripping) with a petroleum solventof a safety type such as Stoddardsolvent or similar materials availableunder various trade names.

7 When amaterial is difficult to remove, car-bon tetrachloride is more effectivethan petroleum solvents. Wear rub-ber gloves to prevent skin irritationwhen using either petroleum sol-vents or carbon solvents are flammable,but comparatively tetrachloride is non-flammable, but is highly toxic. Suit-able ventilation should be providedto avoid breathing vapors. Whenventilation is not sufficient to pre-vent a distinct odor of carbon tetra-chloride, a chemical cartridge respi-rator or gas mask must be Against MoistureThe Motor should not be subject toextreme moisture conditions such ashigh humidity during shut down pe-riods, exposure to water under pres-sure such as hosing down, or severeweather prolonged periods of stor-age, the Motor should be run at leastonce a week, or should be providedwith heaters to guard against mois-ture insulation resistance of motorsnot in regular use should be checkedwith a megger, and, if necessary.
