Keep it in a safe place so that you may refer to it often.
Warning: Before handling these pumps and controls, always disconnect the power first. Do not smoke or use spark-able electrical devices or flames in a septic (gaseous) or possible septic sump.
NOTICE All installations where a sump pump is permanently-wired to the source of electrical supply (control device or junction box) must be performed only by qualified  personnel using the appropriate tools, skills, and knowledge of electrical safety. Such a connection would not be considered readily removable if the plug were cut off the  pump’s power cord. Questions relating to this type of installation should be directed to your local code authority.

Pump Warning

To reduce risk of electrical shock:
Risk of Electrical Shock:
This pump has not been investigated for use in swimming pool areas.

1. This pump is supplied with a grounding conductor and ground ing-type attachment plug. To reduce risk of electrical shock, be certain that it is connected only to a  properly grounded, grounding-type receptacle.
2. Septic tank is to be vented in accordance with local plumbing codes.
3. Do not smoke or use sparkable electrical devices or flame in a septic (gaseous) or possible septic sump.
4. A septic sump condition may exist 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.
5. 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 must be followed for satisfactory performance of your pump. Before installation, check your local electrical and plumbing codes.

1. Provide proper sump
   Minimum Sump Diameter

   W-A1| 18”
   D-A1| 12”
   V-A1| 12”
   Approx. Turn-On Level
   W-A1| 9-1/2”
   D-A1| 10”
   V-A1| 7-7/8”
   Approx. Turn-Off Level
   W-A1| 3-1/2”
   D-A1| 4”
   V-A1| 3-3/8”

2. Make sure float (automatic models) hangs free. It should not come into contact with side or bottom of sump pit.

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

4. Do not set pump directly on the bottom of sump if it is ot solid. Raise the pump by placing bricks or concrete blocks underneath it.

5. Use steel or plastic pipe for all connecting lines be tween pump and sewer outlet.
   NOTICE Some city regulations do not allow in stall ing a pump with plastic pipe. Check local regulations.

6. A check valve should be installed in dis charge pipe, at least twelve inches above the discharge outlet of the pump.

7. Connect to power source using 3-prong grounded 115/230 volt AC receptacle.
   Do not remove ground pin from elec tri cal plug. Do not use an ex ten sion cord.

8. For proper automatic operation make sure the pump power cord is plugged into the back of the “pig gy back” recep tacle on the switch cord.

9. Use pump submerged for pumping waterlike liquids (temperature to 120° F).
   CAUTION: Do not pump flammable liquids, strong chemi cals or salt water.

10. In applications where the pump may sit idle for months at a time, it is recommended that the pump(s) be cycled every few months to ensure the pumping system is  working properly when needed.

11. An audible alarm, such as the should be installed for additional protection against high water conditions.

Your pump warranty is void if…

• power cord has been cut.
• pump has been used to pump mud, cement, tar, abrasives or chemicals.
• pump has been used for pumping of hot water (above 120° F).
• pump has been dismantled by other than authorized service center or distributor.

Pump Servicing

Servicing should be per formed only by an authorized service center.
Warning: Always disconnect the pump from power source before handling or making any adjustments. Always wear rubber boots when there is water on the floor and you  must unplug the pump or make any ad just ments.
NOTICE Automatic thermal overload protects the sealedin-oil motor. Running dry may overheat the motor and activate the overload protector until the unit cools.

Pump does not run or just hums.

1. Line circuit breaker may be off, blown or loose.

2. Water level in sump may be too low to activate automatic float or diaphragm switch.

3. Pump and/or switch cord plug may not be making contact in receptacle.

4. If pump is using the series (piggyback) 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 the unit is being operated by the optional float control switch, unplug the pump from the pig gy back 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 piggyback switch with the float raised up to a  start position, replace the complete piggyback switch assembly and retest with new assembly.

7. If all symptoms check OK, motor winding may be open; take to authorized service center for check.

Pump runs but does not deliver water.

1. Check valve may be installed backward. Arrow on 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.
   Pumps have a small air vent hole in the impeller cavity to let out trapped air. If this hole becomes plugged, pump may air lock. To break the air lock, use a small  screwdriver to clear hole in the impeller cavity.
   As a secondary precaution in installations of this type —1 ⁄16” hole should be drilled in the discharge pipe below the check valve. The check valve should be 12 to 18  inches above pump discharge. Do not put check valve directly into pump discharge opening.
   NOTICE in sumps where the pump is operating daily, air locking rarely occurs.

4. Pump head may be too high. Pump cannot deliver water over 25’ vertical lift.
   Horizontal distance does not affect pumping, except for friction loss through the pipe.

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 out.

Pump runs and pumps out sump but does not stop.

1. Float is stuck in up position.
   Be sure float is not hung up and operates freely in basin.

2. Switch contacts may be stuck; replace switch.

Pump runs but delivers only small amount of water.

1. Pump may be air locked. tart and stop several times by plugging and unplugging cord. Check vent hole in pump case for plugging.
2. Pump head may be too high. Pump cannot deliver water over 25’ vertical lift. Horizontal distance does not affect pumping, except loss due to friction through discharge pipe.
3. Inlet in pump base may be clogged. Remove pump and clean out openings.
4. Impeller or volute openings may be plugged or partially plugged. Re move pump and clean out.
5. Pump impeller may be partially clogged causing motor to run slow, resulting in motor overload. Clear impeller.

Fuse blows or circuit break er trips when pump starts.

1. Inlet in pump base may be clogged. Remove pump and clean out openings.
2. Impeller or volute openings may be plugged or partially plugged. Re move pump and clean out.
3. Pump impeller may be partially clogged causing motor to run slow, resulting in motor overload. Clear impeller.
4. Fuse size or circuit breaker is too small.
5. Defective motor stator; return to authorized service center for verification.

Motor runs for short time then stops. Then after short period starts again.
