More distance between turn-on
and turn-off controls can be used,
but sew age may become septic,
and excessive solids may collect
for the pump to handle. A frequent
pumping cycle is recommended
for best op er a tion.
If an alarm system is used, this
con trol is usually set about 6
inches above the override control.
Making Electrical Connections:
All electrical wiring must be in
ac cor dance with local codes, and
only competent electricians should
make the installations. Complete
wiring diagrams are glued to the
inside cover of the panel. All wires
should be checked for grounds
with an ohm
me
ter or Megger
after the connections are made.
THIS IS IMPORTANT, AS ONE
GROUNDED WIRE CAN CAUSE
CON SID ER ABLE TROU BLE.
IMPORTANT: If equipment
is not properly wired and
pro tect ed as recommended, the
warranty is void.
Heat Sensors and Seal
Failure Connections:
Be sure heat sensor wires are
con
nect
ed in series with the
starter coil. Connections are
provided on the terminal strip.
Pump Operations
Starting System:
1. Turn H-O-A switch to
Off position and then turn on
main circuit breakers.
2. Open all discharge valves and
allow water to rise in sump.
3. Turn H-O-A switch to Hand
position on one pump and
notice operation. If pump is
noisy and vibrates, rotation
is wrong. To change rotation,
interchange any two line
leads to motor 3
f
only.
DO NOT INTERCHANGE
MAIN INCOMING LINES.
If duplex system, check
second pump in the
same manner.
4. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until one
pump starts. Allow pump to
op er ate until the level drops
to turn-off point.
5. Allow sump level to rise to
start other pump. Notice run
lights on panel. Pumps should
alternate on each successive
cycle of op er a tion.
6. Turn both H-O-A switches
to Off position and allow
sump to fill to the override
control level.
7. Turn both switches to Auto
po
si
tion and both pumps
should start and operate
together until level drops to
turn-off point.
8. Repeat this operation cycle
sev er al times before leaving
the job.
9. Check voltage when pumps
are operating and check the
amp draw of each pump.
Check amps on each wire, as
sometimes a high leg
will exist. One leg can be
somewhat higher (5 to 10%)
without causing trouble.
For excessive amp draw on
one leg, the power company
should be con sult ed.
Phase Converters:
Phase converters are generally
not recommended, but in cases
where only single phase current is
available, phase converters can
be used. Be sure to size the
phase converter large enough for
the amp draw specified on the
motor nameplate, not necessarily
by motor horsepower. The
warranty on all three phase
submersible motors is void
if operated with single phase
power through a phase converter,
and 3 leg ambient compensated
extra-quick trip overload
protectors are not used.
