Pump Warning

To reduce risk of electrical shock:

1. Risk of Electrical Shock :
   This pump has not been in ves ti gat ed for use in swimming pool areas.

2. Risk of Electrical Shock: Connect only to a properly grounded receptacle.

   • Septic tank to be vented in accordance with local plumbing codes.
   • Do not smoke or use sparkable electrical devices or flame in a septic (gaseous) or possible septic sump.
   • If a septic sump condition exists and if entry into sump is necessary, then (1) provide proper safety precautions per OSHA requirements and (2) do not enter sump until these precautions are strictly adhered to.
   • Do not install pump in location classified as hazardous per N.E.C., ANSI/NFPA 70 – 2001.
   • Failure to heed above cautions could result in injury or death.

Pump Installation

These important instructions mustbe followed for satisfactory per for mance of your pump:

1. Provide proper sump (rec om mend ed minimum sump diameter is 30″).

2. Do not set pump directly on the bottom of sump if it is not solid. Raise the pump by using bricks or concrete blocks un der neath it.

3. Make sure sump is free of string, cloth, nails, gravel, etc. before installing pump.

4. Risk of electrical shock — connect only to a properly grounded receptacle.

5. Do not remove ground pin from electrical plug.

6. Do not use an extension cord.

7. For proper automatic operation, make sure the pump power cord is plugged into the piggyback receptacle on the diaphragm switch cord.

8. Connect to separate electrical circuit taken directly from main switch.

9. Use steel or plastic pipe for all connecting lines between pump and sewer outlet.
   Note : Some city regulations do not allow installing a pump with plastic pipe. Check local regulations.

10. In applications in which the pump may sit idle for months at a time, it is rec om mend ed that the pump(s) be cycled every month to ensure the pumping system is working properly when needed.

11. HYDROMATIC check valve should be installed in discharge pipe.

12. An audible alarm system such as the Q Alert (indoor use only) for high water con di tions should be installed in every pump for greater protection. Contact your HYDROMATIC distributor for ad di tion al panel applications.
    Warning: When using the automatic diaphragm switch, the vent tube in the plug must be clear of obstructions.
    Do not bend cord. This will cause a crimp in the vent tube and switch failure will occur. Pump should be plugged into a single outlet, where vent tube can “breathe.” Blocking tube or bending cord will void the warranty.

Pump Servicing

Read the following instructions carefully before replacing any parts. Reasonable care and safe methods should be practiced. Check local codes and requirements before installation. Only a com pe tent electrician should make the installations.

Tools Required
General shop tools include socket wrenches and a bearing puller. An ohmmeter is required to thoroughly check motor and wiring. For proper au to mat ic op er a tion, make sure the pump power cord is plugged into the pig-gy back re cep ta cle on the float switch cord. Before removing the pump from its installation for repairs, check first to see if the trouble is caused by:

1. Miswiring of the pump into the terminal block.
2. Miswiring of the float level controls into the panel.
3. Miswiring inside the control panel.
4. Trip circuit breaker. If the breaker is manually reset and then trips off again, the problem could be:
   • a. short circuit in motor or control panel
   • b. water in the motor housing
   • c. insufficient amp capacity of wiring or breakers
   • d. improper panel wiring
5. Tripped overload. If overload is manually reset and then trips off again, the problem could be:
   • a. pump or piping is clogged
   • b. pump motor or bearings may be defective
   • c. start capacitor in motor may have failed
   • d. pump may be miswired to terminal block
   • e. head is lower than rating, pumping too much liquid
6. Air locked pump. Disconnect piping at union and run until all air bubbles are expelled.
7. Wrong impeller rotation. Ro ta tion should be coun ter-clock wise when looking at the impeller. Correct improper rotation on three phase pumps by reversing any two line leads. No rotation check is nec es sary on single phase pumps.
8. Closed discharge gate valve.
9. Plugged impeller or pipeline.
10. Discharge head may be too high. Check elevation against design point of pump.
11. Floats not hanging free in the sump.
12. Malfunctioning floats.

Disconnect power supply.
Checking Power Cord
To be sure wires are not burned off or broken in cord, use ohm-meter for check. Set ohmmeter scale pointer to R x 1 scale and attach one meter lead to white cord wire and one meter lead to black cord wire, then place a screw driv er blade across terminals of plug. If cord is OK, meter needle will go to zero and stay there. If meter needle does not move, this will indicate an open wire and cord must be replaced.

Motor
Warning: Be certain power to pump is off! Disconnect pump power cord from terminals in control panels (manual pump models) and power source
(automatic models) and remove pump from sump.

1. Clean any dirt or trash from the outside of the pump before dis man tling.f the unit is being operated by float or diaphragm switch, unplug the pump from the piggyback receptacle and plug the pump directly into the power source. If the pump starts each time it is plugged directly into the receptacle and does not start each time when plugged into the piggy-back switch with the float raised or the di a phragm switch pressed into the start position, replace the com plete piggy-back switch assembly and retest with new assembly.

2. If motor does not run whentested as described above, the capacitor and/or stator must be checked.
   Disconnect from power supply.
   Remove plug (#6) from top of housing and pour oil into container, preferably clear, so that oil can be observed.

3. If oil is clear, it will indicatemotor is not burned and there has been no water leak into the motor. If oil is cloudy, it will indicate water in motor, or, if oil is black, it will indicate a burned stator.

4. After draining oil, carefullyloosen the power cord assembly (#22) from the motor housing (#2). With power cord loose, remove the four wire nuts and screws (#4) and carefully lift off the motor housing (#2) ex pos ing the capacitor (#28) (1ø only) and the motor assembly.

5. On single phase (1ø) units, check capacitor (#28) using ohmmeter. With ohmmeter scale set at R x 1000, attach meter leads to ca pac i tor. The meter needle should go to zero and come back slowly. If it does not, the capacitor should be replaced.

6. To check motor stator,remove power cord leads from terminal bushings on top of motor (1ø only; 3ø remove wire nuts). If stator is visibly burned, motor assembly must be replaced.

7. Ground check on stator should be per formed using ohm me-ter with scale set at R x 100 and checking meter by putting both meter leads together and adjusting the needle knob until meter reads zero. If meter cannot be adjusted to zero, it will indicate that batteries in meter must be replaced. Always make this test with the meter when scale pointer is set to a new scale before making any checks on the motor. Now connect one meter lead to one terminal of stator and touch and other meter lead to motor stator shell. If needle on ohmmeter goes completely to zero, the motor probably has a wire touching the stator at some point and the motor assembly will have to
   be replaced.

8. Winding resistance test should be performed if the ground test is satisfactory. Use ohm-meter with scale pointer set on R x 1 scale. On this scale, meter reads directly on ohms. Always check the meter with leads together as described above under Ground Check test before making a reading of the winding.Connect one motor lead to the white wire terminal and the other meter lead to the black wire terminal. This reading is for the main winding. If the readings obtained do not agree with those given below, the stator is defective and the motor assembly must be replaced.Reconnect the wires as they were removed.

9. For three phase pumps, remove the power cord assembly (#22) by cutting the butt connection and wire nuts (#32) and remove the power cord from the pump.

10. Twist the three leads of one end of the power cord together. Then at the other end, with an ohmmeter, check any two leads. Also check the third lead with either of the first two. If a zero reading is indicated for any wire, the wire is broken and a new power cord assembly must be ordered.

11. If the winding is grounded, remove the pipe plug in the top of the pump and drain the oil into a clear container. A milky appearance to the oil will indicate that water has entered through worn or damaged seals or O-rings. If this is the case, the mechan-ical seals and all O-rings will have to be replaced.

Seal Housing

• The pump is equipped with two mechanical seals mounted in tandem. The lower seal (#14) and the upper seal (#5) consist of a ceramic stationary seat and a  carbon rotating ring.
• As noted, if water is detected in  the motor housing, inspect the  power cord connection, pipe plug con nec tions, O-rings, the motor housing itself, and the two  mechanical seals.
• There are two quarts of oil in  the motor housing. This is a paraffinic SE-40 process oil.  The same oil is used in the seal housing (#20) between the two mechanical seals. To check the seals, remove the lower housing pipe plug (#8) and pour the oil out into a clean, preferably glass, container. Look for the milky color as noted previously.
• If the oil is clear, the lower seal  is still good. If this seal is  damaged, water will seep in  and continue to stain the oil, changing it from clear, to slightly  discolored, to cloudy, and finally to a milky white.
• Except for very rare instances, the motor will continue to be protected by the upper mechanical seal.

Lower Seal

• If water is found in the seal  chamber, the lower seal must be replaced.  Separate the volute by removing the three cap screws (#9) holding the base (#12) to the upper volute.
• Insert a large screwdriver in the slotted pump shaft and strike the impeller sharply with a plastic  or rubber headed hammer. The impeller should spin free. The impeller holds the rotation carbon ring of the lower mechanical seal against the stationary ceramic seat by compressing a stainless steel spring.
• When the impeller is removed, the spring will relax, allowing  the carbon ring to be removed. There is a rubber sleeve (bellows) inside the spring which grips the pump shaft. This often restricts the spring and must be pried or pulled loose.
• With the carbon ring, spring, and rubber sleeve removed, wedge the ceramic seat out of the housing. Be sure not to scratch or mar the pump shaft.

Upper Seal

1. To remove and replace the upper mechanical seal (#5), the base (#12), impeller
   (#11), lower mechanical seal (#14), and volute (#7) must be removed first. Drain the seal oil from the housing by removing pipe plug (#8).

2. The rotating carbon ring and stainless steel spring are held in place by a snap ring (#27) and washer (#10). Remove these.

3. Remove the four hex head stator bolts and lift the stator (#3). A screwdriver can be inserted under the stator shell in order to remove the stator.

4. Bump the end of the shaft with a plastic hammer. This will push the rotating half of the mechanical seal from the shaft and also push the lower bearing from the seal plate. Now remove the shaft, rotor, and bearing assembly from the seal plate.

5. If water was found in the oil, the rotating and stationary halves of the mechanical seal must be replaced. Remove the stationary seal half by inserting a screwdriver into seal plate from the top and tapping lightly with a hammer.

6. Turning the bearing by hand: if it feels rough when turned or looks rusted, it should be replaced. Obtain a bearing puller to remove the bearing. If a puller cannot be replaced over the bearing, remove the outer face by cracking in a vise. Now the outer face and balls can be removed, allowing the inner face to be pulled.

Reassembly

1. Thoroughly clean the seal plate (#20), particularly the seal and bearing pockets. All sand and dirt must be removed.

2. If the stationary seal half was removed, use a plastic pusher to press it into the housing. Make sure the rubber ring goes in first. Do not use any sharp objects that may damage the seal.

3. When installing a replacement bearing, press only on the inner face and make sure the bearing is flush against the snap ring. If a press is not available, the bearing can be tapped onto the shaft using a sleeve that bears only on the inner face. Pressing on the outer face will ruin the bearing.

4. Push the shaft, rotor and ball bearing assembly into the seal plate, being careful not to chip the ceramic of the stationary seal half.

5. Replace the stator if it is visibly burned or if the ground resistance test or the winding resistance test has failed. Note that the re place ment stator must be of the same manufacture as the existing rotor, or vice versa. Replace the four stator bolts.

6. Remove the old O-ring (#19), regardless of condition, and replace. Place the new O-ring over the seal plate shoulder. Do not roll it. If twisted, water may enter chamber and cause failure.

7. Clean the motor housing thorough ly, then position it onto the seal plate.

8. Press the rotating seal half onto the shaft with the rubber ring facing the impeller. Caution: Mixing old and new seal parts will cause immediate seal failure. When replacing seal, replace both the rotating and the stationary seal halves.

9. Reassemble the lower seal as described.

10. Add a drop of Locktite 222 to the shaft and screw the impeller on hand-tight. The impeller (#11) will force the rotating seal half into position.

11. Set the seal housing (#20) and motor housing (#2) assembly into the volute case (#7) and secure with four hex head screws (#4).

12. To replace the power cord (#22) on single phase pumps, as determined on page 5, first slip the stator lead wires through the holes in the wire seal assembly. Coat the cord grip threads with pipe dope or apply PTFE pipe thread sealant tape and screw the new power cord assembly into the motor housing. Referring to wiring diagrams in this manual, secure wires together. the hot oil will deteriorate the tape and cause motor failure.

13. Before filling the motor housingwith oil, an air test should be performed. Apply 7 to 8 pounds of air pressure in the 1⁄4″ NPT tap on the top of the motor cover and seal chamber.
    Note: Too much pressure will damage the seal.
    Then submerge the pump in water and check for leaks. If a leak occurs, isolate where it is coming from and correct the problem by replacing the sealing part. If there are no leaks, fill the motor and seal housing with high grade trans form er oil, such as Sohio Factopure SE40 or equiv a lent, to at least one inch below top of housing. Do not fill the motor housing completely — allow air space for expansion. Replace oil  plugs (#6). Turn pump on side and fill seal chamber to 1″ from top. Replace plug (#8) and stand pump up.

14. Connect power cord wiresto terminals in panel, or connect power source, and check pump running. Motor should run smooth ly and be free of vibration.

Pump Troubleshooting

Pump does not run or hum.

1. Line circuit breaker may be off, or fuse, if used, may be blown or loose.
2. Water level in sump may be too low. Run in more water.
3. Pump cord plug may not be making contact in receptacle.
4. If pump is using the series cord plug, the two plugs may not be plugged tightly together.
5. Float may be stuck. Be sure float operates freely in basin.
6. If all symptoms check OK,  motor winding may be open; take to service center for check.

Pump runs but does not deliver water.

1. Check valve may be installed backward. Arrow in valve points in direction of flow.
2. Discharge gate valve, if used, may be closed.
3. Pump may be air locked. Start and stop several times by plugging and unplugging cord. Check vent hole in pump case for plugging.
4. Pump head may be too high. Pump cannot deliver water over (SPD50H) 50′ or (SPD100H) 64′ vertical. Pump must be sized to operating con di tions.
5. Inlet in pump base may be clogged. Remove pump and clean out openings.
6. Impeller or volute openings may be plugged or partially plugged. Re move pump  and clean per main te nance instructions.
