CAUTION!
The Three Phase Duplex control panel operates with fl oat switches
to activate pump STOP, LEAD pump START, LAG pump START and
high-level ALARM functions.
1
Ensure all power is turned OFF
before installing fl oats in tank.
Failure to do so could result in
serious or fatal shock.
3
If the fl oats are not properly mounted and connected in the correct
order, the pumps will not function properly.
Floats require free range of motion.
They must not touch each other or any equipment in the pump chamber.
Pipe Clamp Mounting
Label each fl oat and cord end
2
with the provided pairs of
STOP, LEAD, LAG, and ALARM
stickers.
STOP

Mounting the Control Panel
If the distance to the control panel exceeds the length of
the fl oat switch cords or the pump power cord, splicing
in a liquid-tight junction box will be required. For outdoor
or wet installation, we recommend a Liberty Pumps UL
Type 4X junction box.
Wiring the Control Panel
1
Determine conduit entrance locations on control panel as shown.
Check local codes and schematic on the inside cover of the panel
for the number of power circuits required.
Be sure the pump power voltage and phase are the same as the
pump motor being installed.
2
Connect the following wires to the proper terminal positions:
• incoming power
• pump 1
• pump 2
• fl oat switches
See schematic on inside cover of the control panel for details.
Operation
Liberty Pumps Three Phase Duplex control panel operates
with fl oat switches. When all fl oats are in the open or OFF
position, the panel is inactive. As the liquid level rises and
closes the STOP fl oat, the panel remains inactive until the
LEAD fl oat closes. At this point the LEAD pump will turn
ON (if the Hand-O -Auto switch is in the AUTO mode and
the power is ON). The pump will remain ON until both the
STOP and LEAD fl oats return to their OFF positions. If the
liquid level rises beyond both the STOP and LEAD fl oats to
reach the LAG fl oat, the lag pump will turn ON (if the HandO -Auto switch is in the AUTO mode and the power is ON).
Both pumps will remain ON until the STOP, LEAD, and LAG
fl oats return to their OFF positions. If the liquid level rises
to reach the ALARM fl oat, the alarm will be activated.
Alarm System (Indicator Light and Horn)
When an alarm condition occurs, the red light and horn will
be activated.
Transformer
The transformer converts incoming three phase power to
120V to be used for control and alarm.
If the TEST/NORMAL/SILENCE switch is moved to the
SILENCE position and released, the horn will be silenced.
When the alarm condition is cleared, the alarm system is
reset.

Motor Protective Switches
Each pump circuit has motor protective switches that
provides pump disconnect, overload, and branch circuit
protection. Adjust overload to pump FLA.
Hand-Off -Auto (HOA) Switches
The HOA 3-way switches control pump functions.
In HAND mode, the pump will turn ON.
