1 General Information
Before use, read the following instructions carefully. Closely following these instructions will eliminate potential
operating problems, assuring years of trouble-free service.
Risk of electric shock. The pump is supplied with a grounding conductor and grounding-type
attachment plug. To reduce the risk of electric shock, install only on a circuit protected by a
ground-fault circuit-interrupter. Always disconnect the pump from the power source before
handling or making adjustments. Always wear rubber boots when servicing in wet areas. Make
sure the pump power source is a separately fused, grounded 3-wire type receptacle of 15-amp
capacity. DO NOT REMOVE GROUND PRONG OR PLUG. DO NOT USE AN EXTENSION
CORD. Check to make sure installation is in accordance with the National Electric Code and all
applicable local codes. Installation and servicing are to be conducted by qualified personnel.
DO NOT pump flammable liquids
DO NOT use around explosive materials
DO NOT handle unit with wet hands or while standing in water
DO NOT lift the pump by the power cord
DO NOT connect to any voltage other than that listed on the nameplate
DO NOT use in water over 120°F
DO NOT modify the pump in any way
DO NOT expose pump or discharge to freezing temperatures
DO NOT use this product to pump salt water or brine. Use with salt water or brine will void the
warranty. Pump water only.
2 Operation
A. Use the discharge thread on the pump to attach a garden hose. 1/2” and 3/4” barb fittings are included with
the pump for use with 1/2” and 3/4” flexible hose.
B. Set the pump on a hard surface in water.
C. Plug the power cord into a properly grounded 120 volt, 60 Hz, AC power outlet of a 15 amp minimum
branch circuit (see recommended grounding methods in section 1). The pump will operate continuously
whether partly or fully submerged. Submersible utility pumps are intended to pump clean or dirty water at
temperatures up to 120° F.
D. This submersible utility pump is designed for many different pumping requirements such as draining stock
tanks, window wells or flat roofs and cisterns. On a flat surface the pump will pump down to within 1/8” of
the pumping surface. *Note that the pump requires at least 2 inches of water to prime.
E. Do not install the pump on clay, dirt, mud or sand surfaces and clean the area to be pumped. Grass, mud,
sand or pea gravel can clog the pump and reduce its performance.

F. For continuous operation the pump must be submerged to prevent the motor from overheating. If this
occurs, the pump will shut itself off until the motor cools to its normal temperature. Repeated overheating
may cause damage to the pump.
G. Your pump is designed to effectively pump water. Although it will usually pass small particles suspended in
water, grass, heavy mud, sand or pea gravel can clog the pump and reduce the pump’s performance. This
can usually be cleaned out by back flushing with a garden hose through the discharge. The normal
performance that can be expected is as follows:

3 Troubleshooting
Problem Cause Correction
Blown fuse or other interruption of
power; improper voltage. If blown, replace with properly sized fuse or reset breaker; if voltage is under 108V, check
wiring size. Remove extension cord if
connected.
Pump will not run or
hum. Plug on power cord may not be
making contact in receptacle. Check security and connection. If receptacle is corroded, have it replaced by a certified
electrician.
Discharge line may be blocked or
frozen. Make sure line doesn’t pass through cold areas or isn’t blocked.
Vertical lift is beyond pump’s
capability. Model 260 has a maximum lift of 30’ Total Dynamic Head.
Inlet screen of pump is plugged or
the impeller is jammed.
Remove the pump screen and clean inlet and
impeller.
Anti-airlock hole is plugged with
debris.
Clean out anti-airlock hole at base of
discharge tower.
Pump runs or hums
but does not
remove water.
Pump failed to prime due to
insufficient water depth
Prime pump by placing it in a bucket of water
or move it to a deeper area of flooded region.
Pump has met or exceeded its
maximum lift.
Route discharge piping to a lower level. If this
isn’t possible then a larger pump may be
required.
Vertical lift is approaching pump’s
maximum lift capability.
Model 260 has a maximum lift capability of
30’.
Pump runs but
removes very little
water.
Pump’s inlet is partially blocked. Remove volute and make sure inlet is clear of
debris.
Fuse or breaker is too small. A 15-amp breaker should be used.
Other major appliance is on the
same circuit. Pump should be on its own circuit.
Pump is connected to an extension
cord or wiring is inadequate. Have an electrician check for proper wiring.
Circuit breaker trips
or fuse blows when
pump starts.
Defective motor or switch. Consult factory.
