Careful planning of the plant layout will save considerable time and expense, both initially when the installation ismade and later during the operation of the plant. In selecting the location for the pump, consideration should begiven to the fact that a positive suction head at the pump inlet contributes toward the pump efficiency. However, thelayouts of the piping, the arrangement of the fittings, and restrictions in the suction and discharge lines have evenmore effect. For this reason, all fittings and valves should be full opening; all bends should be of long radius orshould be eliminated where possible. Long radius 450 ells should be used, particularly if installed near the fluidcylinder. The following points outline the basic requirements for an installation that will contribute greatly towardgood pump operation.
A. SUCTION LINE
1 . The suction line must not be smaller than the suction intake of the fluid cylinder and may be larger. The lengthof the suction line should be held to a minimum and should run straight from the supply tank to the pump.
2. When bends are required, they should be made with long radius 450 ells. Do not use a bend directly adjacent tothe fluid cylinder. Avoid using any 900 bends if at all possible.
3. Provide a full opening gate valve in the suction line adjacent to the supply tank to permit the line to be drainedwhen necessary. Do not use any type of restricting valve.
4. Do not use meters or other restrictions in the suction line. Eliminate any rise or summit in the suction line whereair or vapor can collect.
5. Pulsation dampening devices are strongly recommended.
6. When necessary to manifold a number of pumps to a common suction, the diameter of the manifold and suctionpipe leading from the supply tank must be such that it has a cross-sectional area equal to, or greater, than thearea of the combined individual suction pipes.
7. When a charging or booster pump is used in the suction line, it must have a capacity equal to twice that of thepump output. This is necessary to provide a charging pump with an output great enough to meet the peakvolume requirements of the plunger pump during the suction stroke and not act as a restriction in the line.
8. All piping, both suction and discharge must be solidly and independently supported. The first support must beas close to the pump as practical. This is necessary to prevent placing the pump in a strain and to keep anyvibration in the system from acting directly on the pump.
B. DISCHARGE LINE
1 . Use a pulsation dampener or a desurger in the discharge line. It should be placed in the line as near the fluidcylinder as possible and ahead of any bend in the line.
2. Do not reduce the size of the discharge line below that of the pump outlet until the line has passed through thedesurger, and is away from the pump approximately 20 feet (6m).
3. Any bend in the discharge line should be made with a long radius 450 elI. Do not use a bend directly adjacent tothe fluid cylinder, particularly a 900 bend.

Installation...I. GENERAL
B. DISCHARGE LINE (Continued...)
4. A pressure relief valve should be installed in the discharge line. The relief valve should be set to operate at apressure no greater than 25% above the maximum rated pressure for the plunger size being used. It should beinstalled in the line ahead of any valve and be piped so that any flow is returned to the supply tank rather thanthe suction line. This will prevent possible damage to the suction line and suction dampener.
5. A by-pass line should be installed to permit the pump to be started without load. This allows oil to circulate andreach all parts in the power end before they are loaded.
C. POWER END
1 . The pump must be mounted level and should be grouted in and free of strain. This applies to a skid-mountedpump or a pump mounted directly on a concrete base.
2. The sheave of a belt driven pump must be correctly aligned with the prime mover sheave. Care must be usedto prevent over-tightening as this will shorten belt life, place the pump in a strain, and cause undue additionalloads on the crankshaft and bearings. Sheave sizes should not be smaller than the minimum approveddiameter.
3. When connecting a direct-driven pump, the shafts must be correctly aligned. Couplings should not be expectedto compensate for avoidable misalignment. With Thomas Flexible Couplings, angular misalignment should notexceed one-half degree. Offset misalignment of the centerlines of the two shafts should not exceed .015" (.381mm). Actually, misalignment should be as small as practical.
4. Provision should be made to stop the pump automatically in the event of supply fluid failure. A pump should notbe run dry, as this causes wear on the packing.
5. Adequate plunger chamber drains have been provided in the pump and should not be plugged. Drain linesshould never be reduced in size from the connection provided.
6. The pump has been drained of oil after testing at the factory and MUST be filled with the proper oil (seepage 11) before starting. The rust inhibiting oil coating inside the power end need not be removed before filling;however, it is recommended that the power end be checked to make sure dirt or contamination has not enteredduring shipment.
D. FLUID END
1 . The fluid cylinder is shipped assembled to the pump complete with valves and cover plates. The stuffing boxes,plungers, and related items have also been assembled and tested with the pump (unless otherwise specified)and require no further assembly. Before the pump is started, these parts should be checked for tightness aswell as for possible damage during shipment.
2. Thoroughly clean the suction line piping before starting the pump. Weld spatter, slag, mill scale, etc., willdamage a pump in a short time.

E. PLUNGER PACKING
The recommended style of packing has been installed and run at the plant. It does, however, require further "settingup" as the pump is started and brought up to pressure. Refer to pages 29 through 34 for correct procedure forpacking used.
F. PLUNGER PACKING LUBRICATION
1 . Automatic packing lubricators are beneficial on all installations and are required on pumps operating at highpressure (1200 psi [85kg/cm 2] and up) to obtain good packing life.
2. When an automatic lubricator is used in water and power oil service, use Rock Drill (Air Drill) oil of properviscosity. For butane-propane service, use NATURAL castor oil. Set lubricator to feed five to seven drops perminute.
G. SUCTION PULSATION DAMPENERS
1. Low Pressure - Plastic Body
a. Some National Ojiwell Varco plunger pumps are equipped with suction pulsation dampeners. Thesedampeners do an excellent job when properly charged and should be kept filled during operation.
A! ATTENTION ! AAt suction pressures over 10 psi (.7kg/cm2), the dampener should be deflated prior to bleeding off the suction
pressure to prevent damage to the diaphragm.
b. The plastic dampener body has an instruction decal attached, which lists the following installation andcharging procedures:
Al ATTENTION ! AHANDLE WITH CARE.
This is a plastic part and can be broken.
c. Tighten capscrews; with 10 to 1 2ft-lbs. of torque.
A!ATTENTION ! AUse thread-sealing compound on check valve and tighten until snug.
OVERTIGHTENING WILL DAMAGE BODY.
d. With pump operating - Charge dampener until bottom of diaphragm is visible through sight glass. Propercharge is when bottom of diaphragm is between center and top of sight glass.

2. High Pressure - Aluminum Body
a. In pressures in excess of 20 psi (1.406 kg/cm2 ) and up to 70 psi (10.545 kg/cm2), it is necessary to use theNational Oilwell Varco high-pressure suction dampener.
b. The high-pressure dampener is charged in a similar manner to the low-pressure plastic dampener, using air ornitrogen to charge the diaphragm and maintain its position in relation to the sight glass.
c. The following procedures should be used to service this dampener:
(1) The dampener is fitted to an adapter that may be either welded into an existing line or be a part of aseparate dampener housing. Place a gasket on each side of the diaphragm retaining plate and place onthe adapter.
(2) The dampener spacer is then placed on top of the retainer plate with the grooved side up and the flat sideagainst the retainer gasket.
(3) The diaphragm fits into the groove on the spacer with the curved portion of the diaphragm above thespacer.
(4) Apply a continuous 1/8" diameter bead of silicone rubber on the outer edge of the diaphragm after it hasbeen positioned into the spacer. This silicone rubber (GE Silicone Rubber or Dow-Corning Silastic) isreadily available at most hardware stores. Assemble the body cover within 10 minutes after applying thesilicone rubber.
(5) Fit the dampener cover over the diaphragm and assemble the capscrews. Tighten these capscrewsevenly to approximately 80 ft-lbs. of torque.
(6) Install the sight glasses, one in each side of the cover. Be sure to seat the sight glass packing carefullyinto the groove on the cover, as this must be an airtight connection.
(7) The air check valve has a pipe thread and must be made up into the cover airtight. Use a good pipethread sealant to promote sealing.

Lubrication...I.GENERAL
NATIONAL OILWELL VARCO Plunger Pumps are "splash" lubricated. The main bearings and crankshaft bearingsare fed by splash. Crossheads and crosshead pin bushings are fed through holes in the crossheads and crossheadreservoir. Intermediate rods are lubricated from the splash they receive from the crosshead.
A. OIL
Use "extreme pressure" gear oil. The chart below shows the recommended grades for various temperatures
surrounding the pump.

Maintenance...I. GENERAL
The following points are intended as a guide to be used in setting up a maintenance program. Good preventivemaintenance will pay big dividends in the form of reliable service with a minimum of trouble.
A. DAILY MAINTENANCE
1. Check power end oil level daily. Do not attempt to check the oil with the pump running. Inspect the oil for dirt orcontamination and change if necessary. An increase in oil level indicates fluid end leakage into power end.Change oil immediately and check intermediate rod wipers and surface smoothness of rod. Check for plungerpacking leakage.
2. Lubricate plunger packing frequently. Packing life can be greatly increased by greasing every four (4) hourswith a small amount of grease. Grease is not recommended at pressures above 1200 psi. Use an alternatepacking lubricator to drip the proper oil of the plunger for lubrication. (See page 9 for further details).
3. Check lubricator for proper level and operation.
4. Check plunger packing for excessive leakage. Replace packing as required.
5. Check stuffing box adjusting nuts for tightness.
6. Drain plunger leakage sump tanks if required.
7. Flush plunger chamber drain lines with kerosene on power oil pumps and fresh water on salt pumps. This maybe done weekly unless salt and paraffin accumulation is severe.
8. Make sure suction and discharge line valves are fully open.
9. Check for leakage between the fluid cylinder and frame or stuffing box to fluid cylinder packing if required.
10. Check all seals for leakage.
11. Check belts or clutch for slippage. If either condition exists, correct immediately.
B. MONTHLY MAINTENANCE
1 . Drain and refill crankcase every six (6) months or as often as required to maintain a clean, sludge-free oil of theproper viscosity.
2. Clean crankcase air breather with a non-explosive solvent.
3. Check all studs, nuts and capscrews for tightness. Inspect gaskets for leaks; tighten or replace as required.
4. Clean pump. Good housekeeping is a prerequisite to good maintenance.

Maintenance ...1. GENERAL (continued) ...
C. STORAGE
If the pump is to be idle for longer than one (1) week, it should be prepared for storage as follows:
1 . Drain and clean crankcase thoroughly. Leave drain open and install 900 elbow, pointing downward, to permit aircirculation and prevent condensation build-up.
2. Coat all bearings, finished surfaces, and entire inside surface of crankcase with a rust inhibiting oil.
3. Remove plungers and packing, clean and coat with rust inhibiting oil.
4. Remove fluid cylinder valves allowing cylinder to be thoroughly cleaned and drained.
5. Coat entire cylinder, valves and parts, with a rust inhibiting oil.
6. Thoroughly inspect pump and rotate crankcase once each month. Re-coat with rust inhibiting oil wherenecessary.
D. START-UP AFTER STORAGE
Any pump that has been in storage, either after field use or as shipped from the plant, will need a thorough
inspection to make sure it has not been damaged in any way and that all parts are properly in place.
A!ATTENTION ! AFAILURE TO OBSERVE THE FOLLOWING POINTS CAN RESULT IN SERIOUS DAMAGE.
1 . Remove all covers on both power end and fluid end; thoroughly clean and inspect all parts and finishedsurfaces.
2. Check all bearings to make sure they are clean and in good condition.
3. Make sure valves, plungers and packing are properly installed and in good condition.
4. Carefully tighten all bolts, nuts, studs and working connections.
5. Fill power end to the proper level with clean oil of the proper viscosity. Make sure oil is poured into thecrosshead reservoir and is worked into all bearings.
6. Fill packing lubricator and pump lines full. Check by breaking connection at stuffing box, working lubricatorplunger until oil appears.

Ov rhaul and Repair...I. GENERAL
The bearings and other working parts in the power end have been designed for continuous duty, and if properlylubricated, will provide years of trouble-free service. However, after the pump has been in service for a long periodof time, the bearings and other working parts will gradually loosen, and if not corrected, will lead to more serioustrouble. The time to overhaul the pump will vary; depending on the operating conditions, and is therefore a matterthat must be left to the good judgment of the operator. Complete disassembly and assembly procedures arediscussed in their respective sections.
A. TOOLS REQUIRED
Most of the tools required to overhaul the pump will be found in an ordinary set of mechanics hand tools. Thespecial tools and equipment required, and not furnished, with the pump include a torque wrench, bearing puller, anda valve servicing kit. Also, a hot oil bath capable of reaching a temperature of 300OF (1490C) will be needed.
B. CHECK POINTS AND ADJUSTMENTS
1 . 2S-1 & 5S-2:
The crankshaft main bearings are single row; shim adjusted, tapered roller bearings. They have beenassembled and adjusted at the factory with proper clearance and will give long trouble-free service. The properclearance is found by adjusting the amount of shims until the crankshaft has .001" to .003" endplay and willrotate freely.
2. 11 D-2, 22T-2, & 32T-2:
The crankshaft main bearings are single row; shim adjusted, tapered roller bearings. They have beenassembled and adjusted at the factory with proper clearance and will give long trouble-free service. The properclearance is found by adjusting the amount of shims until the crankshaft has .002" to .004" endplay and willrotate freely.
3. 310Q-2:A
The 31 Q-2 has two single rows, shim adjusted, tapered roller end bearings. They have been assembled andadjusted at the factory with proper clearance and will give long trouble-free service. The proper end clearanceis found by adjusting the amount of shims until the crankshaft has .004" to .006" endplay and will rotate freely.The 310Q-2 also has two steel backed Babbitt center mains which are non adjustable. The center mains shouldhave .010" to .018" (.254 mm to .457 mm) total diametrical clearance. This is non adjustable.
4. 2S-1, 5S-2, 11 D-2, 22T-2, 32T-2, & 31 Q-2:
a. The connecting rod shell bearings or inserts are precision made steel backed Babbitt lined and require noshims for adjustment. Tolerances are listed on the following page.
b. The normal clearance between the crosshead and crosshead bore is .003" (.076 mm) to .00g" (229 mm).The maximum allowable clearance, including wear, is .012" (.305 mm).
c. The wrist pin bushings must be pressed into the connecting rods and reamed to size. The allowableclearance between the pin and bushing is listed on the following page.

1. 838 PACKING
It is important that the following procedure be observed when replacing old packing to prevent rapid packingwear. 838 packing is assembled in units consisting of a pressure ring along with a top and bottom adapter.Each set will have two or three units. Pay attention to the arrangement of the old packing sets to ensure thenew sets are installed correctly. Another check is the units are installed so the lantern ring is positioned underthe lubrication port. If the lantern ring does not align with the lubrication port, the pump is not correctly packed.
a. Remove cradle cover and rotate pump to bring the first plunger to the forward position.
b. Back off gland nut one or two rounds.
c. If the pump has intermediate rods a back-up wrench is required. The plunger and intermediate rod separateat the knurl area interface. Using the back-up wrench break the plunger loose and unscrew from theintermediate rod. Remove the plunger through the fluid cylinder opening.
d. If the pump does not have an intermediate rod, use a pipe wrench on the knurled area of the plunger andbreak it loose from the crosshead. Unscrew and remove through the fluid cylinder opening.
e. Remove the gland nut, old packing, and packing adapters. Note the order of the packing and adapters. Cleanthe stuffing box and inspect for any damage.
f. Rotate the pump to bring the next plunger forward.
g. Repeat steps "b." through "f." until all the plungers and packing have been removed.
h. Check the throat bushing, lantern ring, and follower for excessive wear. These items can often be reused, but ifthey are worn, replace them. Reusing worn trim will cause premature packing failure.
i. Lightly lubricate the stuffing box bore and install the throat bushing.
j. Lightly lubricate a packing unit and install each component separately insuring each component is fully seatedat the bottom of the box before installing the next component. Repeat and install the second unit. (DO NOTGREASE).

r. Repeat steps "h." through "q." until all cylinders have been repacked.
s. Tighten gland nuts finger tight. Some braided packing is very sensitive to gland tightening. Do not over tighten.
t. Start the pump and bring up to pressure. Watch the packing carefully for signs of excessive heat. If thepacking starts to smoke, back the gland off a little. Braided packing does normally drip a small amount. This isby design and helps keep the packing from over heating.
u. Continue to slowly tighten the nut to reduce the leakage to an acceptable level. Remember this type of packingdoes leak a small amount and tightening the gland until all leakage has stopped will usually result in excessiveheat and failed packing. This style packing is adjustable packing and will have to been inspected regularly tokeep the nut tight and leakage to a minimum. If the pump is allowed to operate with too loose packing, thepacking will prematurely fail and you run the risk of damaging the stuffing box.

As with any plunger pump, the necessity for having an adequate suction head and proper piping design of bothsuction and discharge cannot be over emphasized.
A! ATTENTION ! ANOISY VALVES, DUE TO IMPROPER FILLING, CAN LEAD TO SHORT LIFE AND RAPID MECHANICAL WEAR
OF THE POWER END PARTS.
B. VALVE COVERS
A CAUTIONATHE VALVE COVERS, AS USED WITH THE NATIONAL OILWELL VARCO PLUNGER PUMPS, MUST BE KEPTTIGHT AT ALL TIMES. DUE TO THE DISCHARGE PRESSURE APPLYING A CONSTANT LOAD TO THECOVERS, IT IS NOT POSSIBLE TO CHECK THEIR TIGHTNESS WITH THE PUMP RUNNING OR WITHPRESSURE IN THE CYLINDER.
Bleed off the discharge pressure and check the tightness of the covers as outlined under the assembly procedurefor the type of cover used.
C. VALVE COVER SEALS
Tapered Seat Valves: The cover seals should be replaced as required.
D. VALVE SPRINGS
The springs used with the NATIONAL OILWELL VARCO valves are made of inconel alloy or other stainless steel.
A! ATTENTION ! ATHESE SPRINGS SHOULD BE CHANGED APPROXIMATELY ONCE A YEAR IN ORDER TO ASSURE PROPER
VALVE ACTION AND ELIMINATE THE POSSIBILITY OF A SPRING BREAK.
E. VALVE AND SEAT
Tapered Seat Valves: There are three basic valve & seat assemblies available, depending on the type of service.They are the severe duty (abrasion resistant) tapered seat valves, the disc tapered seat valves, and the sphericaltapered seats.

3. VALVE INSPECTION PROCEDURE (See Figure 5 for part reference)
a. RETAINER
The retainer will not need to be replaced very often. It should be inspected for corrosion or to see if it hasbeen warped or bent. If this is the case, replace the retainer because this can cause undue wear on thespring and improper valve action.
b. SPRING
The spring is made from inconel or other stainless steel and will work in most corrosive environments. Itshould be inspected for wear and/or nicks. If such evidence is apparent, the spring should be replaced.
c. INSERT
The valve insert is made from polyurethane. A good insert is vital for good sealing in slurries or dirty fluids.Inspect the insert for tears, nibbling, and extrusion. If the insert is worn, replace it. Generally you canreplace the insert a couple of times before having to replace the valve body.
d. THREAD LOCK
The thread lock is a nitrile rubber. It is used to lock the retainer and prevent it from backing off during pumpoperation. If the thread lock is torn or damaged, replace it.
e. VALVE BODY
The valve body is heat-treated 17-4 PH stainless. Inspect the body for excessive wear, cracks, or washing.The guides should also be inspected for proper fit in the seat and any cracks or excessive wear. Replace thevalve body when these conditions are present. If replacing the valve body, a new insert should also be used.
f. SEAT
The seat is also a heat-treated 17-4 PH stainless steel. It should be inspected for excessive wear and/orwash on the seating surface. Also check the taper for signs of wash by or wear. If any of these conditionsexist, the seat should be replaced. Do not use an old valve body with a new seat.
Wth the seat out of the pump also inspect the liquid end seating area for washing or excessive wear. Theseats should fit in the liquid end with a small amount of stand off. If the liquid end seating area is washed orthere is no stand off on the seats, the liquid end will have to be repaired. This type of repair will require theservices of a machine shop.

Storage of Pumps...I. GENERAL
All machinery units require protection from corrosion erosion, natural attrition which causes deterioration of thesurface as well as the working parts. Generally, units in operation are frequently inspected, cleaned, painted andlubricated while idle units are often more or less neglected. Any degree of neglect is costly, especially if continued overa sufficient period of time to make restoration of the equipment impossible. It is recommended that preventive measuresof protection be established and the following will guide you in the minimum requirement.
A. GENERAL
Preferably, units should be stored in clean, climatically controlled buildings. This would require the minimuminspection, but, since storage in older environments is sometimes necessary, more frequent inspections and additionalprotection is necessary. The schedule for inspection and protection can be determined only at the point of storage. Aprotection and storage log is recommended. Tropical areas require the maximum protection; arid regions require theleast amount of protection. The frequency of inspection is determined after noting the rate of deterioration. Takepositive action immediately when corrosion/erosion appears, do not wait until large areas are covered because usuallythe larger the area, the deeper the penetration.
B. RECOMMENDED PROTECTION INITIAL STORAGE
1 . Drain all oil and thoroughly clean inside of Power Frame.
2. Coat pinion shaft oil seals with grease.
3. Remove breathers for later installation on pump. Seal all breather holes with greased solid pipe plugs. Removeextension rods and diaphragm sealing housing; be sure to protect the rods and housings, storing themseparately for later installation on the pump. Seal diaphragms with wooden covers. "Mate' the wood cover anddiaphragm faces together, thoroughly coating with Rust Veto 342 or its equivalent.
4. Spray two gallons of Shell VSI 100 vapor phase inhibitor or equivalent into power end of pump.
5. Remove valves and valve springs. Clean and wrap in corrosion inhibiting paper. Remove liners and pistons.Clean and wrap in corrosion inhibiting paper. Clean and dry fluid end bores and thoroughly coat all internalsurfaces with Tectyl 506 or equivalent.
6. Thoroughly coat all threads and end of valve cover and screw into fluid end.
7. Protect all external machine surfaces using Rust Veto 342 or equivalent including pump pads.
8. Inspect complete pump and record all details on the Protection and Storage Log.

2. When servicing, all power sources to the motor and to the accessory devices should be de-energized and disconnected and all rotating parts should be at standstill.
3. Lifting means, when supplied, are intended for lifting the motor only. When two liftingdevices are supplied with the motor a dual chain must be used.
4. Suitable protection must be used when working near machinery with high noise levels.5. Safeguard or protective devices must not be by-passed or rendered inoperative.6. The frame of this machine must be grounded in accordance with the National Electric Code
and applicable local codes.7. A suitable enclosure should be provided to prevent access to the motor by other than
authorized personnel. Extra caution should be observed around motors that areautomatically or have automatic re-setting relays as they may restart unexpectedly.
8. Shaft key must be fully captive or removed before motor is started.9. Provide proper safeguards for personnel against possible failure of motor-mounted brake,
particularly on applications involving overhauling loads.10. Explosion proof motors are constructed to comply with the label service procedure manual,
repair of these motors must be made by TECO-Westing house Motor Company or U/L listedservice center in order to maintain U/L listing.
LOCATION1 . Drip-proof motors are intended for use where atmosphere is relatively clean, dry, well
ventilated and non-corrosive.2. Totally enclosed motors may be installed where dirt, moisture, or dust are present and in
outdoor locations.3. Explosion-proof motors are built for use in hazardous locations as indicated by
Underwriters label on the motor.4. Chemical duty enclosed motors are designed for installation in high corrosion or excessive
moisture locations.Note: in all cases, no surrounding structure should obstruct normal flow orventilating air through or over the motor.
MOUNTING1 . Mount motor securely on a firm, flat base. All ball bearing normal thrust motors up to and
including 256T frame size may be side-wall or ceiling mounted; all others check nearestTECO-Westinghouse office for mounting recommendations.
2. Align motor accurately, using a flexible coupling if possible. For drive recommendations,consult with drive or equipment manufacturer, or TECO-Westing house.
3. Mounting bolts must be carefully tightened to prevent changes in alignment and possibledamage to the equipment. The recommended tightening torque s for medium carbon steelbolts, identified by three radial lines at 120 degrees on the head, are:
Bolt Size Recommended Torque (Ft-lb.)Minimum Maximum
2/8 25 371/2 60 90
15/8 120 18013/4 210 320
4. V-belts Sheave Pitch Diameters should not be less than those shown in Table 1 (NEMArecommended values)
5. Tighten belts only enough to prevent slippage. Belt speed should not exceed 5000 ft. permin.
*Max. Sheave width = 2(N-W) - .25**Max Sheave width = N-W***Sheave ratios grater than 5:1 and center-to-center distance less than the diameter of the
large sheave should be referred to TECO-Westi ng house.
POWER SUPPLY & CONNECTIONS1 . Wiring of motor and control, overload protection and grounding should be in accordance
with National Electrical Code and all local safety requirements.2. Nameplate voltage and frequency should agree with power supply. Motor will operate
satisfactorily on line voltage within -10% of nameplate voltage; or frequency with -5% andwith a combined variation not to exceed -10%. 230-volt motors can be used on 208-voltnetwork systems, but with slightly modified performance characteristics as shown on thenameplate.
3. Dual voltage and single voltage motors can be connected for the desired voltage byfollowing connection diagram shown on the nameplate or inside of the conduit box.
4. All Explosion Proof motors have Temperature Limiting Devices in the motor enclosure toprevent excessive external surface temperature of the motor in accordance with U/Lstandards. Terminals of thermal protectors (P1 & P2) should be connected to the motorcontrol equipment, according to the connection diagram inside of the conduit box.
5. Standard connection diagram for three phase, not thermally protected, dual rotation motorsare shown in diagrams A through E.(Note: To change rotation, Interchange any two line leads)

*Important: For Part Winding Start, M2 contactor should be closed within two (2) secondsafter M1 contactor is closed.Only 4 pole and above (e.g., 6P, 8P ) motors are satisfactory for Part WindingStart at low voltage.
START UP1 . Disconnect load and start motor. Check direction of rotation. If rotation must be changed,
ALLOW THE MOTOR TO STOP COMPLETLEY. Interchange any two leads of a three-phase motor.
2. Connect load. The motor should start quickly and run smoothly. If no, shut power off atonce. Recheck the assembly including all connections before restarting.
3. If excessive vibration is noted, check for loose mounting bolts too flexible motor supportstructure or transmitted vibration from adjacent machinery. Periodic vibration checksshould be made; foundations often settle.
4. Operate under load for short period of time and check operating current against nameplate.
TESTINGIf the motor has been in storage for an extensive period or has been subjected to adversemoisture conditions, it is best to check the insulation resistance of the stator winding with amegometer. Depending on the length and conditions of storage it may be necessary toregrease or change rusted bearings.If the resistance is lower than one megohm the windings should be dried in one of the followingtwo ways:1. Bake in oven at temperatures not exceeding l94iF until insulation resistance becomes
constant.2. With rotor locked, apply low voltage and gradually increase the current through windings
until temperature measured with a thermometer reaches 194iF. Do not exceed thistemperature.
MAINTENANCE
INSPECTIONInspect motor at regular intervals. Keep motor clean and ventilation openings clear.
LUBRICATION1 . Frame 143T-256T: Double shielded and pre-lubricated ball-bearing motors without grease
fittings and don t need relubrication, except on MAX-E1" and MAX-E2" products whichhave regreasable features.
2. Frames 280TS, 320-449TZ(TS): Motors having grease fittings and grease dischargedevices at brackets. Motors are shipped with grease for initial running. It is necessary torelubricate anti-friction bearing motors periodically, depending on size and type of service.See Table 2 to provide maximum bearing life. Excessive or too frequent lubrication maydamage the motor.
