end through the delivery carrier. Damage cannot be processed from
the factory.
PUMP CAUTIONS AND WARNINGS
1. WARNING: Before handling these pumps and controls, always
disconnect the power rst. Do not smoke or use sparkable
electrical devices or ames in a septic (gaseous) or possible
septic sump.
2. WARNING: Risk of Electrical Shock – This pump is supplied
with a grounding conductor and grounding-type attachment plug.
To reduce risk of electrical shock, be certain that it is connected
only to a properly grounded, grounding-type receptacle.
• Septic tank to be vented in accordance with local plumbing
codes.
• DO NOT remove cord or strain relief. DO NOT connect
conduit to pump. Electrical installations shall be in accordance
with the National Electrical Code and all applicable local
codes and ordinances.
• A septic sump condition may exist and if entry
into sump is necessary, then (1) provide proper
safety precautions per OSHA requirements and
(2) do not enter sump until these precautions are strictly
adhered to.
• This pump has not been investigated for use in swimming
pool areas.
3. Tank should be vented in accordance with local plumbing codes
and should not be installed in locations classied as hazardous.
4. WARNING: Severe injury may result from accidental contact
with moving cutters. Keep clothing, hands and feet away from
cutters any time power is connected to the pump.
CALIFORNIA PROPOSITION 65 WARNING:
This product and related accessories contain
chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm.
PUMP INSTALLATION
The cutter blades are on the suction side of the positive displacement
pump impeller and discharge directly into the inlet of the impeller.
The integral stainless steel pump motor shaft is sealed by a single
mechanical seal.
Two ball bearings are used to handle the loads in this design. The
upper bearing takes radial loads, while the larger lower bearing
handles both thrust and radial loads. Both bearings are permanently
lubricated by the dielectric oil in the motor housing. The motor is
xed within the motor housing and is completely submerged in the
dielectric oil for maximum heat transfer. The motor housing and seal
chamber are completely sealed with O-rings located at mating part
faces.
The power cord entry system is designed to give reliable sealing.
The rst seal is made by compression of a rubber gasket by the cord
grip, thereby expanding to ll the cord entry of the motor housing.
The cord grip forms a second seal around the molded cord end and
provides strain relief.
Application:
These pumps are designed for residential sewage discharge
applications with a pH ranging from 5 to 9, specic gravities from
0.9 to 1.1, viscosities ranging from 28 to 35 S.S.U. and temperatures
up to 140°F.
Pump Not Operating or in Storage:
Pumps with carbon ceramic seals must be manually rotated (6
revolutions) after setting nonoperational for 3 months or longer and
prior to electrical start-up.
Installing Pump in Sump:
Before installing pump in sump, lay it on its side and rotate grinder
shaft. Stator boot and rotor may be slightly stuck due to factory
test water so it must be broken loose by rotating shaft with a
screwdriver at the grinder end. The common shaft should turn with
a slight resistance. Slight lubrication by means of a small amount of
lubricating oil down the cavity inlet of the stator boot and rotating
shaft to prelube stator boot and rotor before start is recommended.
Do not connect the power until after this test. Clean all trash and
sticks from sump and connect pump to piping. A check valve must be
installed on each pump.
Location:
If pumps are installed in an existing basin or concrete sump, the
piping can either be connected permanently or rails and brackets can
be furnished for mounting to walls of basin. In either case, be sure
that the check valve is used and that the pumps are submerged in
a vertical position. The complete factory built packaged system is
recommended for the most satisfactory and economical installation.
Making Electrical Connections:
All electrical wiring must be in accordance with local code, and only
qualied electricians should make the installation. All wires should
be checked for shorts to ground with an ohmmeter or megger after
the connections are made. This is important, as one grounded wire
can cause considerable trouble.
PUMP OPERATIONS
To start the pump, perform the following steps
in order:
1. Grinder pump is single phase; no rotation check
is necessary.
2. Run water into sump until motor is covered.
3. Open gate valve in discharge line.
4. Turn pump on. If pump runs and sump liquid does not pump
down, stop pump and close discharge gate valve. Lift pump until
sealing ange is open to vent off trapped air. Lower pump, open
discharge valve, and start the pump again.
CAUTION: Positive displacement pump is designed to operate at
minimum 5 GPM capacity. Running pump at shut-off condition
or with gate valve closed can result in damage to the pumping
stator boot and rotor.
5. Level control should be set so that pump turns off when level is
about 2 inches above inlet of pump suction and turns on when
level is about 2 inches above motor.
6. If problems occur, check power source.
Make sure a separate supply line is available.
Verify voltage supply.
7. Check resistance of windings. If not within guidelines, return
pump to authorized factory service center.

As the motors are oil lled, no lubrication or other maintenance is
required. Pump should be checked every quarter for corrosion
and wear.
PUMP MAINTENANCE
Inspecting Cutter Parts:
1. Close gate valve at pump discharge.
2. Turn off circuit breaker.
CAUTION: Never work on pump with power on. Be sure ground
wire from pump is connected to a good ground such as a water
pipe.
3. Remove pump from sump.
4. Remove screws and stationary cutter ring assembly. Radial cutter
can be screwed off the common shaft by lightly tapping cutter
and unscrewing counterclockwise while holding end of common
shaft with a screwdriver in slot at cutter end of shaft.
5. Radial cutter and stationary cutter can now be inspected for wear
and replaced if necessary.
