Figure 3 shows a typical connection for 1 phase 120 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
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 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.
