B - INSTALLATION 1. The float and rod, when used, must be mounted as shown and partially adjusted before the pump is lowered into the sump. a. Insert float rod through the rubber bellows on the support plate or pit cover. Slide a float rod collar onto the lower end of the float rod, then the float, then an additional float rod collar. 4 2. Place the support plate sealing gasket around the rim of the sump, aligning the holes in the gasket with the foundation bolt holes. Carefully lower the pumping unit into the sump, placing the discharge pipe in the desired position and aligning the holes in the support plate with the foundation bolts. 3. The support plate (23) must rest evenly at all points and must be level before it is bolted to the sump rim. Shim and grout to level the support plate, then partially tighten foundation bolts. Turn pump shaft by hand to be sure that it rotates freely. Continue to tighten foundation bolts, checking shaft rotation until bolts are snug. 4. Install couppling halves (42 & 44) on the motor shaft and pump shaft according to coupling manufacturer’s recommendations. 5. Lift the motor over the frame (19) and carefully lower the motor until it rests on the frame. Insert and tighten cap screws (219). 6. Connect the power leads to motor terminals according to motor wiring diagram and to motor control or starter and test for proper motor rotation, refer to section “Direction of Rotation”. 7. When proper rotation established, complete the coupling assembly and tighten coupling set screws. Rotate pump shaft several times by hand to be sure that shaft rotates freely. If shaft binds, refer to section on “Pump Adjustments”. 8. Make permanent power lead connections to the float switch and/or starter and motor. Note: Float switch must provide overload protection for the motor or an across-the-line magnetic starter, providing overload and low voltage protection for the motor, plus a float switch, is required for use with the pump. 9. Push the float switch arm down to its lowest position. Lift the float rod about 1/2” and slide the top float rod collar against the switch arm and tighten the set screw. Position the lower float rod collar about 1/2” below the float switch arm and tighten the set screw. CAUTION: Do Not overgrease ball bearings. The following lubricants are recommended for this pump. Ball thrust Bearings: Shell Alvania #71012 or equal. Stuffing Box Packing: Shell Alvania #71012 or equal. Shaft Bearings: For standard bronze or iron bearings use a water resistant grease such as Shell Alvania EPRO #71030 or equal. Motor Bearings: Follow motor manufacturer’s Instructions as to the type of grease and frequency of lubrication. E - PUMP ADJUSTMENTS If after making the installation, the pump shaft does not rotate freely or if there is vibration in the pumping unit, the following adjustments are recommended. 1. Place entrance switch in the off position and separate the coupling halves so that the shaft turns free. 2. Bend the tang of the lockwasher (69) clear of the top lock nut (22) and unscrew the lock nut. Hold the pump shaft (6) with a strap wrench and turn the bottom adjusting nut (22) counter clockwise to lower the shaft until the impeller just rubs the suction cover (7) when the shaft is rotated. Tighten the lower adjusting nut (22) by turning clockwise 1/6 turn or approximately 60º to obtain an impeller clearance of .008” to .010”. This setting will give maximum performance under normal operating conditions. 3. Tighten the top lock nut (22) and bend the tang of the lockwasher into the slot of the lock nut. Check again to see that shaft turns freely, then engage coupling halves and reconnect power. 10. Connect discharge pipe to pump discharge. Note: The discharge pipe must be properly supported so that the weight of the pipe and fittings do not rest on the pump discharge connection as this may cause pump misalignment. A check valve and gate valve should be installed near the pump discharge to prevent possible pump damage due to reverse flow upon pump shut-down. 11. Start the pump and check for proper rotation. The pump should operate smoothly and without vibration. If the pump vibrates, there may be distortion of the pump support plate or discharge pipe. Relieve this strain until the pump operates without vibration. Refer to section on “Pump Adjustments”. C - DIRECTION OF ROTATION Before placing pump in service, the proper direction of rotation must be established. If pump rotates in reverse rotation the shaft coupling might unscrew and cause a bent shaft or broken impeller or casing. These pumps normally operate in right hand or clockwise direction when looking down on top of the motor, however, pumps specified for left hand rotation will rotate counterclockwise. See rotation arrow on the pump. Jog control to test rotation. If rotation is incorrect, on three phase current, interchange the two main power leads at the starter and test rotation again. On single phase current, if motor rotation is reversed, consult motor manufacturer or his representative. When proper direction of rotation is established, mark power leads to starter terminals. D - LUBRICATION All pump and component parts have been lubricated at the factory before shipment. Periods of subsequent lubrication depend upon operating conditions. Periodic inspection of the bearings and packing box lubrication is necessary and additional grease should be added as required. 5 4. Improper alignment of the discharge pipe (161) may cause the shaft to bind. Loosen the top pipe lock nut (254) two or three turns and test for shaft rotation. If shaft is free, gradually tighten the pipe lock nut again, checking for shaft rotation as the nut is tightened. 2. Disengage the flexible shaft coupling, following manufacturer’s recommendations. Remove motor cap screws (219) then remove the motor from the frame (19), also remove foundation bolts from support plate. 5. If shaft still binds, lift pump from the sump and loosen the bottom pipe lock nut below the support plate (23). Continue to tighten the top pipe lock nut and the binding should be relieved. Tighten the bottom pipe lock nut. when maximum shaft freedom has been obtained and make sure the top pipe lock nut tight. 3. Lift the pumping unit with support plate from the sump to a horizontal position on the floor or other suitable support. 6. 7. 8. G - LIQUID END DISASSEMBLY 1. Lubrication or flush lines (335) have been furnished to the bottom and intermediate bearing assembly (99). Check adjustment of the pipe lock nuts above and below the support plate for proper adjustment as in number 5 above. Remove cap screws (215), suction cover (9) and gasket (73). Place gasket in water. 2. Remove impeller screw (26) by turning counter clockwise, also remove impeller washer (270). Pull impeller (2) from the shaft and lift key (32) from the keyway in the shaft. An accurate adjustment of the pump impeller and alignment can be established by the use of a watt-meter to measure minimum current requirement of the motor as the adjustments are being made. 3. Remove cap screw (265), cap screws (267) and hex nuts (268) at the casing discharge flange and place gasket (336) in water also dismantle lube pipe assembly (335) to the bottom bearing assembly. 4. Unscrew cap screws (212) and remove casing (1) from casing adapter (71). Place gasket (73A) in water. Unscrew cap screws (226) and remove casing adapter (71), gasket (241) and bottom guide bearing assembly (99) from shaft. Place gasket in water. Top Column Closure - The stuffing box packing (13) is properly adjusted when the gland (17) is tight enough to prevent gases from escaping along the shaft but does not prevent the shaft from turning freely. Excessive gland pressure will cause the packing to wear on the shaft and increase power consumption. If it is necessary to remove discharge pipe (161) from the pump, remove discharge flange (295) or coupling, top pipe nut (294) and gasket (254) then remove pipe and elbow (105). F- GENERAL MAINTENANCE AND REPAIR Care should be exercised in keeping all parts of the pump clean when the pump is disassembled. Special precautions should be taken to keep ball bearings dirtfree at all times. Any part which is excessively worn or deteriorated should be replaced with new parts before reassembling the pump.

Frequently asked questions
This pump is designed for pumping raw or treated sewage, light sludge, slurries, industrial wastes, and similar liquids containing solids.
The pump should be installed in a vertical wet pit, and the motor and flexible shaft coupling should be installed at the job site.
You can adjust the impeller clearance by loosening the top pipe lock nut and turning the bottom adjusting nut clockwise.
All pump and component parts have been lubricated at the factory before shipment. Periods of subsequent lubrication depend upon operating conditions. Periodic inspection of the bearings and packing box lubrication is necessary and additional grease should be added as required.
Refer to the "Locating Trouble" section of the manual to troubleshoot common issues with the pump.
