CAUTION:
Do
excessive force when operating
the shutoff valve or damage to
the valve or valve handle may
occur. The valve is closed when
a noticeable stop is felt upon
closing. The valve is completely
open upon 9 full counterclockwise
turns from the closed position.
Step 3
Check for proper voltage of
incoming power with a voltmeter.
Step 4
Ensure H-O-A switch is in
the Off position and turn on main
breaker.
Step 5
Start
the
pump
by
the H-O-A switch to the Hand
position.
Step 6
Check
the
pump
with clamp on ammeter on black
pump lead. Readings higher
than nameplate indicate clogged
pump, miswiring, or improper
voltage. If basin is not being
pumped down and amperage
readings are considerably lower
than nameplate, then the pump is
air locked.
NOTE: Nameplate amperage is
rated at the largest impeller
diameter trim.
Pumps with
smaller diameter impellers will
draw slightly less amps than
nameplate.
If pump is air
locked, refer to the trouble
check list section 4 in this
manual. If pump does not run,
check that the white, black and
red pump power leads are
properly connected to the
terminals in the control panel
marked "W", "BK" and "R".

Step 7
Float Adjustment for
Simplex Systems:
Adjust floats so that the pump
starts when the water level is just
above the pump motor housing,
and the pump shuts off when the
water level is 2 inches above the
pump volute discharge.
Float Adjustment for
Duplex Systems:
Adjust floats so the lead pump
will start when the water level is
just above the motor housing. The
lag pump start float should be 5
to 6 inches above the lead pump
start float. Adjust pump shut-off
so that water level is within 2
inches
turning
discharge. Pumps should alternate
starting, between each other,
upon
cycles. To check lag pump level,
set both H-O-A switches to Off
amperage
position and allow water to surpass
the lag pump level, then set both
H-O-A
position and both pumps should
start. Turn off one pump and be
sure second pump starts when lag
pump level is reached on second
trial. If pumps fail to cycle in this
manner, retrace control float
wiring to panel.
Step 8
Ensure H-O-A switch(s) is set to

service.

Troubleshooting
WARNING: Hazardous moving
parts.
To
reduce
injury, disconnect power before
servicing pump.
WARNING: To reduce risk
of electric shock, pump is
provided with grounding wire.
Be certain that it is connected
to ground.
WARNING: To reduce risk of
electric shock, do not remove
pump cord or strain relief.
The following list describes
possible problems and possible
solutions. Refer to the pump and
panel installation and service
manuals for details regarding any
necessary adjusting, dismantling or
repair work.
