PAGE B - 5 INSTALLATION
Motor Cable Grounding Test
The electrical power used to operate
this pump is high enough to cause inju­
ry or death. Make certain that the power
cable receptacle is properly grounded
after installation.
Using a volt‐ohm meter, connect one lead to the
motor cable green/yellow ground lead. Connect
the other lead to an uninsulated point on the pump
body. The test circuit should close.
If the test circuit does not close, there is a defect in
the cable or motor which must be corrected.
Liquid Level Devices
The pump is furnished with built‐in devices to auto­
matically regulate liquid level by filling and dewa­
tering. When liquid level reaches the on‐point (up­
per) device, the pump will switch on and continue
to run until liquid level falls below the off‐point (low­
er) device.
NOTE
Distilled water or uncontaminated rain water may
fail to provide conductivity necessary to trigger the
automatic liquid level sensing devices built into the
pump. If this occurs, ground the on‐point assembly
to convert the pump to manual operation, and
install a float level control system.
Overheating will occur if the liquid level falls
below the level required to cool the pump
motor (see LIQUID LEVEL in Operation,
Section C).
