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 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.
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:
An acceptable motor control switch shall be provided at the
time of installation.
C-4.1) Power Cord:
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 applicable
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. NOTE:
THE WHITE WIRE IS NOT A NEUTRAL OR GROUND
LEAD, BUT A POWER CARRYING CONDUCTOR.
C-4.2) Overload Protection :
C-4.2-1) 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.
