ELECTRICAL SAFETY  
1. grounded tools must be plugged into a gFCI (ground Fault Circuit Interrupt-  
er) outlet, properly installed, and grounded in accordance with all codes and  
ordinances. never remove the grounding prong or modify the plug in any  
way. Do not use any adapter plugs. Check with a qualified electrician if you  
are in doubt as to whether the outlet is properly grounded. If the tools should  
electrically malfunction or break down, grounding provides a low resistance path to  
carry electricity away from the user.  
2. double insulated tools are equipped with a polarized plug (one blade is wider  
than the other). This plug will fit in a polarized outlet only one way. If the  
plug does not fit fully in the outlet, reverse the plug. If it still does not fit,  
contact a qualified electrician to install a polarized outlet. Do not change  
the plug in any way. Double insulation  
eliminates the need for the three wire  
grounded power cord and grounded power supply system.  
3. Avoid body contact with grounded surfaces such as pipes, radiators, ranges,  
and refrigerators. There is an increased risk of electric shock if your body is  
grounded.  
4. do not abuse the Power Cord. never use the Power Cord to carry the Sump  
Pump or pull the Plug from an outlet. Keep the Power Cord away from heat,  
oil, sharp edges, or moving parts. Replace damaged Power Cords immedi-  
ately. Damaged Power Cords increase the risk of electric shock.  
PERSOnAL SAFETY  
1. Stay alert. Watch what you are doing, and use common sense when operat-  
ing this product. Do not use the Sump Pump while tired or under the influ-  
ence of drugs, alcohol, or medication. A moment of inattention while operating  
this product may result in serious personal injury.  
2. dress properly. do not wear loose clothing or jewelry. Contain long hair.  
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,  
jewelry, or long hair can be caught in moving parts.  
3. Use safety equipment. Wear AnSI-approved safety impact goggles when  
assembling this product. Non-skid safety shoes must be used for appropriate  
conditions.  
TOOL USE And CARE  
1. disconnect the Power Cord Plug from the power source before making any  
adjustments, changing accessories, or storing the Sump Pump. Such pre-  
ventive safety measures reduce the risk of starting the unit accidentally.

the outlet. If the Power Plug or electrical outlet does get  
wet, do not unplug the Power Cord. Disconnect the fuse or  
circuit breaker that supplies power to the Pump. Then,  
dEVICE  
unplug the Power Cord and examine for presence of water  
in the outlet. (See drip Loop, right.)  
CORd  
10. If necessary, have a certified electrician install (within 10 feet of where the  
Pump will be located) a 115 volt, gFCI electrical outlet that is dedicated only  
to the Pump. Any outlet should be above the water line.  
11. nEVER raise or lower the Pump by its electrical Power Cord.  
12. In cold weather, when the Pump is not in use, protect the interior of the Pump  
from freezing by draining the water and pumping a permanent type automo-  
bile anti-freeze containing a rust inhibitor through the system. A 50% mixture  
with water is recommended. Be sure to flush the system with a neutralizing liquid  
prior to re-use of the Pump.  
13. If an extension cord is used (for temporary use only) connections must not  
come in contact with water or any wet surfaces.  
14. Prior to use, and periodically thereafter, check to make sure all connections  
are tight and secure.  
15. Industrial applications must follow OSHA requirements.  
16. Performance of this product may vary depending on variations in local line  
voltage.

2. As the distance from the supply outlet  
increases, you must use a heavier  
gauge extension cord. Using exten-  
sion cords with inadequately sized  
wire causes a serious drop in voltage,  
resulting in loss of power and pos-  
sible tool damage.

ASSEMBLY And OPERATIng InSTRUCTIOnS  
note: For additional information regarding the parts listed in the following pages, refer  
to the Assembly diagram on page 13.  
WARnIng! Always make sure to turn off the electricity powering the  
Pump’s electrical outlet and that the Pump is unplugged from its outlet prior to  
assembling the unit, unclogging the unit, or making any adjustments to the unit.  
1. If necessary, have a certified electrician install (within 10 feet of where the Pump  
will be located) a 115 volt, GFCI electrical outlet that is dedicated only to the Pump.  
Any outlet should be well above the water line.  
2. The discharge has both internal and external NPT threads. Use either 1-3/4” NPT  
Male or 1-1/2” NPT Female PVC pipe for the discharge line. Do not use a pipe  
smaller than 1-1/2”.

3. Connect the Discharge Pipe to the Base (25). nOTE: Make sure the Discharge  
Pipe is secured to a solid surface, with appropriate hardware (not included), to  
ensure the stability of the Pump. (See Figure E.)  
4. Install an additional union (not included) or other means of separating the Dis-  
charge Pipe just above the floor to facilitate removal of the Pump if necessary.  
(See Figure E.)  
5. A check valve (not included) is recommended just above, or in place of, the union  
to prevent the backflow of water after each pump cycle. If a Check Valve is used,  
a 1/8” diameter air bleed hole should be drilled through the Discharge Pipe just  
above the lower Base (25) to prevent Pump “airlock”. A small spray of water out of  
this hole is normal while the Pump is running. (See Figure E.)

6. Carefully set the Pump in place. do not lower or raise the Pump by the Power  
Cord or discharge Pipe. (See Figure E.)  
7. The Float Switch (2) automatically switches on and off at a water depth of approxi-  
mately 4 inches. The ON/OFF height can be manually changed by adjusting the  
Float Switch Lock. CAUTIOn: Do not run the Pump dry. Doing so will increase  
wear to the unit and possibly cause seal damage. (See Figure E.)  
8. nOTE: This Pump has a built-in thermal protector for the Motor which automati-  
cally shuts it off to avoid overheating. After the Motor cools, it will cycle back on.  
Wait for the cycle to continue. Do not try to turn on the Pump manually after it has  
automatically shut off.  
9. Connect additional Discharge Pipe as needed to direct the water discharge to  
the desired location. The discharge should be kept as short as possible with a  
minimum number of turns. IMPORTAnT: Do not exceed the maximum lift of the  
Pump:  
Model 95591 = 20 Feet.  
Model 95592 = 24 Feet.  
Model 95593 = 26 Feet.  
10. Connect the Power Cord & Plug to its 115 volt, GFCI electrical outlet, while making  
sure to form a “drip loop” in the Power Cord. (See drip Loop, page 5.)  
11. When the water level exceeds approximately 4 inches the Pump will automatically  
turn on and run continuously until the water level falls below 4 inches at which time  
the Pump will automatically turn off.  
12.  
WARnIng! When shutting off power to the Pump, always shut off the electrical  
power to the GFCI outlet first. Then, disconnect the Pump’s Power Cord & Plug  
from the GFCI outlet.  
InSPECTIOn, MAInTEnAnCE, And CLEAnIng  
WARnIng! Always shut off the electrical power to the GFCI outlet first. Then, dis-  
connect the Pump’s Power Cord & Plug from the GFCI outlet prior to performing  
any inspection, maintenance, or cleaning procedures.  
1. Before each use, inspect the general condition of the Pump. Check for cracked  
or broken parts, damaged electrical wiring, clogged Impeller Cover, Impeller, Dis-  
charge Pipes, and any other condition that may affect safe operation. If abnormal  
noise or vibration occurs, have the problem corrected before further use.  
do not use damaged equipment.

2. To clean the Impeller Cover and Impeller: A clogged or dirty Impeller Cover  
or Impeller (28) will greatly reduce performance of the Pump. To clean the Impel-  
ler Cover (31), spray the Cover with clean water. To clean the Impeller, remove  
the nine Screws (32) at the bottom of the Base (25). Then, remove the Base to  
expose the Impeller Cover and Impeller. Use a stream of clean water to clean the  
Impeller and Impeller area inside the Pump. Then, replace the Base. (See Assy.  
diagram.)  
3. When finished, store the Pump in a clean, dry and safe location out of reach of  
children. In cold weather, when the Pump is not in use, protect the interior of the  
Pump from freezing by draining the water and pumping a permanent type automo-  
bile anti-freeze containing a rust inhibitor through the system. A 50% mixture with  
water is recommended. Be sure to flush the system with a neutralizing liquid prior  
to re-use of the Pump. note: Always properly dispose of all used anti-freeze.  
CAUTIOn! All maintenance, service, or repairs not mentioned in this manual  
must only be performed by a qualified service technician.
