9. Pull the power cords up, through the center electric cord
hole and install the electric cord grommet, into the cover.
10. Install the 2" vent pipe into the 2" FNPT threaded vent
grommet. The vent pipe must go through the roof of the
building or it can be connected to an existing vent pipe.
The sewage basin must be vented.
Explosion hazard. Improper ventilation of
sewer gases can result in leakage of methane sewer gas,
and a possible explosion of fumes, resulting in severe injury
or death. Vent basin according to all local codes.
NOTICE: Proper ventilation is also needed to prevent
negative basin pressure and to provide the necessary air
for proper aerobic activity within the basin.
11. Install the 2" check valve in the horizontal portion of the
discharge pipe. See Figure 1. Make certain, the flow indi-
cating arrow, points away from the pump. This check
valve will keep the water from running back into the basin
when the pump is not running.
Extend vent through roof
or connect to existing vent.
Purchase vent and
discharge pipes locally.

12. Double check the connection between the discharge pipe
and the septic or sewage tank. They must be connected
before the pump is plugged in.
13. Insert the float switch piggy-back plug into a properly
grounded outlet.
14. Plug the pump into the piggy-back plug.
15. Check the operation by filling the sump basin with water
and observing pump operation through one complete cycle.
Make sure that no parts of the assembly interfere with the
float.
Failure to make this operational check may
lead to improper operation, premature failure, and flooding.
OPERATION
The shaft seal depends on water for lubrication and cooling.
Do not operate the pump unless it is submerged in water as
the seal may be damaged if allowed to run dry.
NOTICE: Do not allow the pump to run in a dry sump. It will
void the warranty and may damage the pump.
An automatic overload protector in the motor will protect the
motor from burning out due to overheating/overloading. When
the motor cools down, the overload protector will automati-
cally reset and start the motor.
If the overload trips frequently, check for the cause. It could
be a stuck impeller, wrong/low voltage, or an electrical failure
in the motor. If an electrical failure in the motor is suspected,
have it serviced by a competent repairman.
The pump is permanently lubricated. No oiling or greasing is
required.
MAINTENANCE
Hazardous voltage. Can shock, burn, or kill.
Before removing the pump from the basin for service, always
disconnect electrical power to the pump and the control
switch. Do not lift the pump by the power cord. See the "Cord
Lift Warning" below.
After removing the basin cover and the necessary discharge
piping, lift the pump out of the basin.
Place the pump in an area where it can be cleaned thor-
oughly. Remove all scale and deposits on the pump.
Submerge the complete pump in a disinfectant solution
(chlorox or chlorine bleach) for at least one hour before dis-
assembling the pump.
The pump motor housing contains a special lubricating oil
which should be kept clean and free of water at all times.
1. Attempting to lift or support pump by power cord
can damage cord and cord connections.
2. Cord may pull apart, exposing bare wires with
possibility of fire or electrical shock.
3. Lifting or supporting pump by power cord will
void warranty.
4. Use lifting ring or handle on top of pump for all
lifting/lowering of pump. Disconnect power to
pump before doing any work on pump or
attempting to remove pump from sump.
