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 its 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 float, 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 float 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 3 inches on BP Series and 6 inches on SE Series
above the pump bottom.
6.) Figure 3 shows a typical connection for pumps with the
wide angle float and 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 int outlet.
C-4) Electrical Connections:
An acceptable motor control switch shall be provided at the
time of installation.
C-4.1) Power Cords:
The cord assembly mounted to the pump must not be modified
in any way except for shortening to a specific 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 -
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 rectified 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.
