Installation and Service
Both a check valve and a shut-off valve are recommended for each pump. The
check valve is used to prevent backflow into the sump. The shut-off valve is used to
manually stop system flow during pump servicing.
Electrical Connections
Power Cable:
The power cable mounted to the pump must not be modified in any way. This pump is
provided with a 3 wire cord and 3 prong grounded plug that must be connected into a
3 wire grounded Ground Fault receptacle. Do not bypass grounding wire or remove
ground prongs from plug. This pump requires a separate, properly fused and grounded
branch circuit. Use of a ground fault circuit interrupter (GFCI) is strongly recommended.
The electrical outlet or panel shall be within the length limitations of the pump power
cord, and at least 4 feet above floor level to minimize possible hazards from flood
conditions. Do not use an extension cord.
IF USED with Control Panel:
Any splice between the pump and the control panel must be made in accordance with
the electric codes. It is recommended that a junction box if used be mounted outside
the sump or be of at a minimum NEMA 4 Construction if located within the wet well.
DO NOT USE POWER CABLE TO LIFT PUMP
Always rely upon a Certified Electrician for Installation
Overload Protection:
Single Phase:
The stator 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.
IMPORTANT!
The overload 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 corrected immediately.
WARNING : DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS.
If current through the temperature sensor exceeds the values listed, an intermediate
control circuit relay must be used to reduce the current or the sensor will not work
properly.
Wire Size: If longer power cable required, consult electrician for proper wire size.
Any splice between the pump and the control panel must be made in accordance with the
electric codes. It is recommended that a junction box if used be mounted outside the sump,
or be of NEMA 4 Construction at a minimum, if located within the wet well.
