Installation
Before You Install Your Pump
Pump clean water only with this pump.
NOTICE: This unit is not designed for applications
involving salt water or brine! Use with salt water or brine
will void warranty.
To avoid clogging the pump and damaging the shaft
seal, do not pump water containing solids, foreign
material, sand, silt, or abrasives. Always have the suction
strainer installed when the pump is operating. Failure
to use a strainer may cause the pump to fail and void
the warranty.
Clean the strainer and flush out the pump after each
use. Make sure all of the hose and pipe connections
in the suction line are tight. An air leak in the suction
line will prevent the pump from priming and reduce
pump performance.
Tighten all of the piping joints to the pump hand tight
+1-1/2 turns only. Overtightening may break the pump
and will void the warranty.
Do not allow the pump or any system component to
freeze. Freezing will void the warranty.
Periodically inspect the pump and the
system components.
Priming The Pump
All suction connections must be airtight. Make sure the
suction lift is not more than 25 feet (7.6M).
NOTICE: 'Priming' refers to the pump expelling all air in
the system and beginning to move water from its source
out into the system. It does not refer only to pouring
water into the pump (although pouring water in is
usually the first step).
Burn Hazard. NEVER run the pump dry.
Running the pump without water may cause pump to
overheat, damaging seal and possibly causing burns
to persons handling the pump. Running pump without
water can damage the impeller and may damage the
seal, causing leaking or flooding, and will void the
warranty. Fill the pump with water before starting it.
Follow the steps below.
1. Remove the priming plug.
2. Make sure the suction and the discharge valves
and any hoses on the discharge side of the pump
are open.
3. Fill the pump and suction pipe with water
4. Replace the priming plug, using
or Teflon™ based joint compound on the thread;
tighten the plug.

NOTICE: If a priming tee and plug have been
provided for a long horizontal run, be sure to fill the
suction pipe through this tee and replace the plug.
(Use Teflon™ tape on the plug.)

5. Start the pump; water should be produced in
10 minutes or less. The time will depend on the
depth to water. If no water is produced within
10 minutes, stop the pump, release all the pressure,
remove the priming plug, refill the pump and pipe
and try again.

NOTICE: Check valve or foot valve required to maintain
pump prime.
Locate the pump as near as possible (vertically) to the
water source, to keep the suction lift (distance from
the water to the pump) as low as possible. Place the
pump on level support. Protect against excess moisture
and flooding.
Long pipe runs and many fittings increase friction and
reduce flow. Use the smallest possible number of fittings
and the shortest possible run for piping.
Support the weight of the pipe.
Be sure the water is clear of debris which can clog the
pump, such as sand, dirt, or scale. Be sure the foot valve
and the pipe are clean and in good condition; scale or
dirt in the foot valve can cause the valve to leak. Valve
leakage may cause the pump to lose its prime, which can
result in pump failure.
