Electrical / Installation / Operation
Permanently ground pump before connecting power cable
to power supply. Connect ground wire to approved
ground first, then connect to equipment being installed.
Do not ground to a gas supply line.
Float switches or any other approved motor control must
match motor input in full load amperes.
For more information, contact your local code officials.
Installation Wiring Instructions
Pump has two power supply wires (Red/Black) and one
ground wire (Green).
Fasten power supply wire leads securely to control panel;
leave 4-5" of slack in leads at this point. Securely fasten
leads to plastic pipe within 6" of the pump discharge sec-
tion.
NOTICE: To avoid dropping pump or damaging wires or
splices, NEVER allow pump wires to support weight of
pump.
PUMP INSTALLATION
Risk of electrical shock. Do not remove or
alter cord. Do not connect conduit to pump.
1. Only qualified personnel should install the pump and
associated control equipment.
2. Vent sewage tank according to local code.
3. Do not install pump in any location classified as
hazardous by National Electrical Code, ANSI/NFPA
70-1984.
Submersible

4. These pumps are intended for permanent connection
only. Provide strain relief at control panel for power
supply cord connection to box. All control compo-
nents must be UL listed and suitable for end use
application.
5. Do not pump flammable liquids, strong caustics, or
strong acids with this pump. Do not use with salt water
or brine.
6. To prevent dropping pump, lower it by the drop pipe,
not by the cables. The electrical cables will not hold
the pump weight.
7. Discharge outlet is 1-1/4" NPT threaded.
NOTICE: If installing external check valve, hold dis-
charge with pipe wrench to prevent loosening dis-
charge in shell.
8. If pump is to be operated with an open discharge, a
discharge valve must be installed. Before startup, open
this valve about 1/3 open. Start pump. Slowly open
valve until the desired flow rate is reached. Final set-
ting must be within pump's recommended operating
range.
OPERATION
1. The pump must be submerged at all times during nor-
mal operation. Do not run pump dry.
2. Make sure that the float switches are set so that the
pump stops before the pump runs dry or breaks suc-
tion. If necessary, adjust float switches to achieve this.
3. The motor bearings are lubricated internally. No main-
tenance is required or possible on the pump.
