6.) Figure 3 shows a typical connection for pumps with the wide angle
float and piggy-back plug. for manual and automatic operations.
Automatic- Plug float cord into GFI outlet, then plug
pump cord into float cord.
Manual- Plug pump cord directly into GFI outlet.
C-4) Electrical Connections:
WARNING !
PUMPS MUST BE PROPERLY GROUNDED PER THE NATIONAL ELECTRIC CODE AND YOUR
LOCAL ELECTRIC CODE. IMPROPER GROUNDING VOIDS WARRANTY.
C-4.1) Power Cable:
The cord assembly mounted to the pump must not be modified in any way. This pump comes complete with a 3 wire
cord and 3 prong grounded plug that must be connected into a 3 wire grounded Ground Fault receptacle.
DO NOT
remove ground pin from electrical plug. It is NOT recommended to use an extension cord with these pumps.
Do not use the power cable to lift pump.
C-4.2) Overload Protection:
Automatic thermal overload protects the sealed-in-oil motor, running dry may overheat the motor and trip the
overload. The type of in-winding overload protector used is referred to as an inherent overheating protector and
operates on the combined effect of temperature and current. This means that the overload protector will trip out and
shut the pump off if the windings become too hot, or the load current passing through them becomes too high. It will
then automatically reset and start the pump up after the motor cools to a safe temperature. In the event of an overload,
the source of this condition should be determined and rectified immediately.
DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION OCCURS !
NOTE: All item numbers ( ) refer to Figure 4.
