RISK OF SERIOUS INJURY OR DEATH
WARNING
 Do not modify the pump/pump system in any way.
Modifications may affect seals, change the electrical loading
of the pump, or damage the pump and its components.
 All pump/pump system installations shall be in compliance
with all applicable Federal, State, and Local codes and
ordinances.
 Vent basin in accordance with local code. Proper venting of
sewer gases alleviates poisonous gas buildup and reduces the
risk of explosion and fire from these flammable gases.
 Wear adequate Personal Protective Equipment when working
on pumps or piping that have been exposed to wastewater.
Sump and sewage pumps often handle materials which can
transmit illness or disease upon contact with skin and other
tissues.
 Do not remove any tags or labels from the pump or its cord.
 Keep clear of suction and discharge openings. To prevent
injury, never insert fingers into pump while it is connected to
a power source.
All Pro370 and vertical discharge Pro380-Series models come
factory-equipped with the float switch mounted on the QuickTree
assembly. These models come with two cords—one to the float
switch and the other to the pump motor. The switch cord has a
series (piggyback) plug enabling the pump (motor) cord to be
plugged into the back of it (Figure 13). The purpose of this design
is to allow manual operation of the pump.
NO!
Figure 13. Piggyback Plug Installation
For automatic operation, the two cords should be
interconnected and plugged into a separately fused, grounded
outlet of proper amp capacity for the selected pump model. Both
cords are equipped with 3-prong plugs and must be plugged into
a properly grounded 3-wire receptacle. Do not remove the
ground prongs.

Operation
Copyright © Liberty Pumps, Inc. 2018 All rights reserved.
For manual operation, or in the event of switch failure, the pump
cord can be separated and plugged into the electrical outlet
directly, bypassing the switch. 200V/230V single-phase pumps
should only be operated without the float switch by using the
circuit breaker or panel disconnect. Do not let the pump run dry.
If the pump will be wired directly into a control device or junction
box, and it is necessary to remove the plugs, have a certified
electrician do the wiring in accordance with the National Electric
Code and applicable local codes. See Figure 14 for typical direct
wire installation of single-phase, automatic pumps.
RISK OF SERIOUS INJURY OR DEATH
WARNING
 In 200V/230V installations, one side on the line going to the
pump is always "hot", whether the float switch is on or off. To
avoid hazards, install a double pole disconnect near the
pump installation.
