Figure 3 shows a typical connection for 1 phase 240 volt 

pumps with the piggy-back plug, for manual and automatic 

operations. 

Automatic -

 Plug float cord into outlet, then plug 

 

pump cord into float cord.

 

Manual -

 Plug pump cord directly into outlet. 

IMPORTANT! - When Installing Vertical Float 

Pumps, Check To Be Sure Float Is Not Hung 

Up On Top Of Volute Housing. 

C-4) Electrical Connections:

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 receptacle. 

DO NOT

 

remove ground pin from electrical plug. It is 

NOT

 recom-

mended 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 cur

-

rent. 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 ! 

SECTION D: SERVICE AND REPAIR

  

WARNING ! - DO NOT overfill oil. Overfilling of 

motor housing with oil can create excessive 

and dangerous hydraulic pressure which can 

destroy the pump and create a hazard. Overfill

-

ing oil voids warranty. 

D-1) Bottom Plate:

Remove screws, and remove bottom plate from volute and 

remove volute. Clean and examine impeller. If impeller 

vanes are clogged, or it is excessively worn or broken, the 

impeller should be replaced. 

D-2) Impeller:

After removing the bottom plate the impeller, may be 

removed by turning impeller counterclockwise to remove 

from shaft. When reassembling the impeller, turn the 

impeller clockwise until it bottoms against shaft. Replace 

volute, bottom plate, and screws.
