INSTALLATION
PIPING INSTALLATION
Hazardous voltage. Can shock, burn or kill. Do not lift
pump by the power cord. See "Cord Lift Warning" on Page 3.
Piping must not be smaller than pump discharge.
When installed in a sewage system, the pipe must be capable of
handling spherical solids of at least 2" (51mm) in diameter.
The rate of flow in the discharge pipe must keep any solids present in
suspension in the fluid. To meet minimum flow requirements (2 feet
per second in the discharge line), size the pipe as follows:
A Pipe Size
2" (51mm)
2-1/2"(64mm)
3"(76mm)
In a sewage system use a 2" (51mm) check valve (purchase separately)
in the discharge pipe to prevent backflow of liquid into sump basin.
The check valve should be a free flow valve that will easily pass solids.
Be sure check valve installation complies with local codes.
For best performance of check valve when handling solids, do not
install it with the discharge more than 45° above the horizontal. Do
not install the check valve in a vertical position as solids may settle in
the valve and prevent it from opening on startup.
ELECTRICAL INSTALLATION
Hazardous voltage. Can shock, burn, or kill. When
installing, operating, or servicing this pump, follow the safety
instructions listed below.
•
DO NOT splice the electrical power cord.
•
DO NOT allow the electrical cord plug to be submerged.
•
DO NOT use extension cords. They are a fire hazard and can
reduce voltage sufficiently to prevent pumping and/or damage
motor.
•
DO NOT handle or service the pump while it is connected to the
power supply.
•
DO NOT remove the grounding prong from the plug or modify
the plug. To protect against electrical shock, the power cord is a
three-wire conductor and includes a 3-prong grounded plug. Plug
the pump into a 3-wire, grounded, grounding-type receptacle.
Connect the pump according to the NEC or CEC and local codes.
For automatic operation, plug or wire the pump into an automatic
float switch or duplex controller. The pump will run continuously when
plugged directly into an electrical outlet.
Connect or wire pump to its own individual branch circuit with no
other outlets or equipment in the circuit. Size fuses or
circuit breakers according to this manual's "Motor, Switch, and Cord
Specifications" chart.
Risk of electrical shock and fire. Be sure that power
supply information (Voltage/ Hertz/Phase) on pump motor nameplate
matches incoming power supply exactly. Install pump according to all
electrical codes that apply.
BASIN PACKAGE INSTALLATION
Read and understand the instructions in this manual before your
concrete floor is poured.
NOTICE: Proper ventilation is needed to prevent negative basin
pressure and to provide air for proper aerobic activity within the
basin.

The sewage basin should be located at the lowest place in the
basement or area to be drained. Floor drains from other areas in
the basement may be tiled into the basin. Drain tile around a house
foundation may also be tiled into the basin, effectively removing
water and relieving pressure from this area.
Basin covers are used to exclude refuse from the basin.
1. Dig the hole for the sewage basin and the sub-base. The hole must
be deep enough so that the finished floor is flush with the top of
the basin (Figure 1). The sub-base requires 4" of sand or gravel/
crushed rock. Crushed rock pieces should not be larger than 1/2"
while the recommended diameter of the pea gravel pieces should
not exceed 3/4".
2. Level the sub-base out until it is smooth. Sharp rock can damage
the basin.
3. Install the basin on top of the sub-base.
4. Backfill around the basin with crushed rock, with a maximum
diameter of 1/2", or use pea gravel.
5. Slide the inlet coupling (purchase separately) up the inlet pipe
enough to allow positioning of the pipe against the open end of
the spud on the basin. Lubricate the coupling with dish soap if
necessary. With the pipe in position, slide the coupling into place
on the spud and tighten both clamps securely.
ReadThe pipe should pitch down to the basin inlet at 1/4" per foot.
This will cause the water to run into the basin.
6. Install the discharge pipe into the 2" FNPT discharge grommet.
7. 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.
8. Install the 2" check valve in the horizontal portion of the discharge
pipe (Figure 1). Make certain the flow-indication 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.
9. Double check the connection between the discharge pipe and the
septic or sewage tank. They must be connected before the pump
is plugged in.
10. Insert the float switch piggy-back plug into a properly grounded
outlet.
11. Plug the pump into the piggy-back plug.
12. Check the operation by filling the 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.
