C-3) Liquid Level Controls:
Figure 2 shows a typical installation for any submersible pump
using a level control mounted to the discharge piping with a
piggy-back plug.
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 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 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 3.5 inches on
SPRINT II Series and 5.5 inches on SPRINT III 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 into outlet.
The receptacle must be a three pin polarized type with an
internal ground. If existing receptacle is not as described, it
must be changed to the proper type and grounded in
accordance to the electric codes. The receptacle should be
located a minimum of 4ft above floor level.
C-4) Electrical Connections:
WARNING!
ALL MODEL PUMPS AND CONTROL PANELS MUST
BE PROPERLY GROUNDED PER THE NATIONAL
ELECTRIC CODE OR CANADIAN ELECTRIC CODE,
STATE, PROVINCE AND LOCAL CODES. IMPROPER
GROUNDING VOIDS WARRANTY.
C-4.1) Power Cable:
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 the 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 CABLE TO LIFT PUMP.
Single Phase pumps are supplied with a 3 prong plug. The third
prong is to ground the pump to prevent possible electrical
shock.
DO NOT ALTER OR REMOVE THE GROUND
PRONG.
