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 GFI 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 or a minimum
level of 4.50 inches on EHV Series and 6.50 inches
on SEV Series above the pump bottom.
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 GFI outlet, then plug
pump cord into fl oat cord.
Manual - Plug pump cord directly into GFI outlet.
C-4) Electrical Connections:
C-4.1) Power Cable:
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 local 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 cable to lift pump.
WARNING! - The white wire is not a neutral or
ground lead, but a power carrying conductor.
