Step 2:
Connect pump power, seal failure/
heat sensor, and float cords to
panel terminals per the schematic
provided. All conduits and cables
entering the panel must be sealed
off.
For single-phase pumps: Check
panel wiring to ensure white,
black, and red pump leads are
connected according
schematic and panel wire labels.
Single phase pumps will run only
if connected one way.
Three phase pumps: Interchange
any two line leads to the motor
inside the panel if the pump rotates
in the wrong direction.
Do not leave pump in basin unless
it is placed in operation. If a
pump has been out of service for
an extended period of time, with
the power off, rotate the impeller
by turning the radial cutter with
a screwdriver to be sure it rotates
freely.

Step 3:
Turn H-O-A switch to the Off

Step 4:
Start the pump by turning the
H-O-A switch to the Hand position.
Step 5:
Check the pump amperage 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
cut diameter impellers will
draw slightly fewer amps than
nameplate. If pump is air locked,
refer to the troubleshooting
section in this manual.
Step 6:
Float adjustment for simplex
systems: Adjust floats so that the
water level is 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 that a
pump will start when the water
level is just above the pump motor
housing, and pump on override
water level is 5 inches above the
pump motor housing. Adjust pump
shut-off so that water level is
within 2 inches above pump volute
