NOTICE ! Height and/or piping restriction will reduce the pump output performance. See the

performance chart below to insure you have the proper pump for your application. Whenever

possible use the same size or larger pipe as the pump discharge for optimum performance.

Reducing the pipe size will not harm your pump; it will just reduce the output.

USE AND INSTALLATION

Always disconnect the power source before attempting to install, service or

perform maintenance on the pump. Failure to do so may result in fatal

electrical shock. Always disconnect the power source before servicing pump.

Your Superior Pump is designed and built to give you reliable performance and long life. It will
pump water automatically for years when properly installed in the right environment.

REMOVING OLD PUMP. (If necessary)

1. Make sure power supply is disconnected.

2. After the power is off, remove the old pump. There are many different possible types of
installations. It is best to remove all old piping and start over with new piping. Be sure to clean all
debris and dirt out of the sump basin before installing your new pump. Be sure to have a
grounded 120V AC outlet mounted within 6 ft. of your sump basin. Again, it is highly
recommended that a GFCI (ground fault circuit interrupter) outlet be installed in the receptacle
box.

NOTICE !

A qualified electrician must perform all wiring.

INSTALLATION (New Pump)

1. Set your new pump in the bottom of the sump basin off to one side. The pump should be
placed on a solid foundation. Do not place the pump directly on the ground or sandy or
rocky surfaces. Sand and small stones may clog or cause damage to your pump.

2. Make sure the float switch will swing freely from the bottom to top without coming in contact
with the side of the sump basin. Contact with the side of the sump basin may cause the
switch to malfunction. See figure below.

3. It is highly recommended to install a full flow, swing type check valve (not included) as close
to the discharge outlet on the pump as possible. A new check valve will greatly increase the
life of your pump. The check valve should be the same size as the pump discharge.

A. Grounded Outlet. A GFCI outlet is

strongly recommended.

B. Discharge Pipe

C. Full-flow swing type check valve

D. Sump Basin

E. Position pump so the float switch

operates freely without touching the
sides of the basin.

4. Connect the pump and check valve together using schedule 40 PVC pipe and fittings.
You can also use DWV or ABS pipe, as this is not a pressure installation. Corrugated

drain hose is intended for temporary use and should not be used in a permanent

installation. Although there are many types of pipe that work adequately for this
installation, PVC is recommended.

5. Test your installation after you have completed setting up the pump. Plug the cord from
the pump into the piggyback plug of the float switch, then plug that into your grounded
outlet. The pump should not run at this point. If the pump runs, the switch is stuck in the
upright position or the pump is plugged directly into the outlet and not through the
piggyback switch plug. Fill the sump basin with water using buckets or a hose. When the
switch floats to the upright position, the pump will turn on. The switch will turn off the
pump when it reaches the down position. You may adjust the switch to meet your
particular needs. Remember the switch must swing freely without touching the sides of
the sump basin.

NOTE: This pump has a built in anti-airlock device. Leakage is normal from this device.

TROUBLESHOOTING

PROBLEM POSSIBLE CAUSES HOW TO CORRECT

If the pump does
not start or run

Pump is not plugged in, switch or breaker is off Plug pump in or turn on switch/breaker

Check for blown fuses or tripped circuit breakers or
tripped GFCI outlets

Replace fuse, reset breaker, reset GFCI outlet

Float switch is defective Check and replace if necessary
Motor thermal protector tripped Allow pump to cool. Pump will reset

Float switch is stuck or obstructed

Remove obstruction or position pump so it will not
become stuck

The pump starts
and stops too often

Backflow of water from discharge hose/pipe Install or replace check valve
Float switch is defective Replace float switch

If the pump runs
but moves little or
no water

Clogged intake screen Clean or replace screen
Clogged discharge hose/pipe Remove cl og
Frozen discharge hose/pipe Allow hose/pipe to thaw
Pump is air locked Clean out airlock hole with a paper clip or pipe cleaner
Low line voltage Check wire size and increase if necessary
Check valve is stuck in the closed position Inspect, repair or replace if necessary

Check valve is installed backwards

Make sure valve is installed in the correct direction of
flow

Worn, damaged or clogged pump parts

Inspect for wear, damage or clog and clean or replace
if necessary

Discharge head exceeds pump capacity

If pumping height is over 25’, the pump will not move
water. See performance chart

Pump does not
shut off

Float switch is obstructed or stuck Remove obstruction
Defective Float Switch Replace switch
