INSTALLATION
pump must be approved by the Gor-
man-Rupp Company for the application.
Motor Cable Grounding Test
Do not connect the pump control cable
to the control box or incoming voltage
before verifying the pump ground;
otherwise, personnel will be exposed to
serious injury or death.
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 may be controlled to perform filling and
dewatering as shown in Figure B-3 by using the
float switch and liquid level control offered as op-
tions.
Overheating will occur if the liquid level falls
below the level required to cool the pump
motor (see LIQUID LEVEL in Operation,
Section C).
