General Comments:
1) Never work in the sump with the power on.
2) Level controls are factory set for a pumping differential of 9
inches. If that is the cycle desired, simply circle the discharge
pipe with the pipe mounting strap, feed the end through the
worm drive, and tighten with a screwdriver. Be certain that the
level control cannot hang up or foul in it’s swing. Also, make
certain the pump impeller is still submerged when the level
control is in the ‘off’ mode.
3) If a higher pump differential is needed, grip the cord near
the neck of the fl oat, then using the other hand, exert a
steady force on the lower edge of the cable clamp. The cable
clamp should slide up to the new pivot point. Attach the level
control to the discharge hose in the manner described above.
4) Plug the level control plug into the receptacle, then plug
the pump into the piggyback plug. One cycle of operation
should be observed, so that any potential problems can be
corrected.
5) It is recommended that the fl oat should be set to insure
that the sump well liquid level never drops below the top of
the motor housing.
6.) Figure 3 shows a typical connection for pumps with
the wide angle fl oat and piggy-back plug. For manual and
automatic operations
Automatic -
Plug
fl oat cord into outlet, then plug pump
cord into fl oat cord.
Manual -
Plug pump cord directly int outlet.
C-4) Electrical Connections:
An acceptable motor control switch shall be provided at the
time of installation.
C-4.1) Power and Control Cords:
The cord assembly mounted to the pump must not be modifi ed
in any way except for shortening to a specifi c application.
Any splice between the pump and the control panel must
be made in accordance with all applicord electric codes. It is
recommended that a junction box, if used, be mounted outside
the sump or be of at least Nema 4 (EEMAC-4) construction if
located within the wet well.
DO NOT USE THE POWER OR
CONTROL CORD TO LIFT PUMP.
NOTE:
THE WHITE WIRE
IS NOT A NEUTRAL OR GROUND LEAD, BUT A POWER
CARRYING CONDUCTOR.
C-4.2) Overload Protection:
Single Phase (Standard) -
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 rectifi ed
immediately.
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.

power cord length is required. See table for electrical
information.
