QuickTree and Pro680-Series Access Cover
Liberty Pumps' Pro680-Series systems feature QuickTree
technology. The QuickTree float system uses a stainless steel
mounting rod (tree) and specially designed cord clamping
brackets to affix the pump floats in the system. All floats are
preset at the factory at optimum operating levels and should
not be adjusted. Field adjusting floats may cause improper
activation or turn-off of the pump and optional alarm.
QuickTree removal and float inspection: The QuickTree system
is located under the separate access cover to help ease inspection,
service, and replacement of a float. To inspect the floats, simply
unbolt the access cover and lift out the QuickTree assembly from
its holder. There is no need to disconnect plumbing or remove the
pump. Pro680-Series systems feature a manual pump (with no
switch attached directly to the pump). Operation of the pump is
accomplished by the QuickTree system.
Re-inserting the QuickTree: After service or inspection of the
floats, re-insert the QuickTree into its holder. Cords from the
pumps and float switch need to be properly sealed as described in
the Integrated Cord Seal System section.
Integrated Cord Seal System: It is important that cords from the
pump motors and float switch, and optional alarm float are sealed
in the specially designed rubber sealing channels under the access
cover. Proper sealing is required to keep sewer gas from leaking
from the system. Place the cords securely in the rubber channels
as shown in Figure 7 [left], being careful to remove excessive cord
"slack" from inside the system.
IMPORTANT: Three cord channels are provided. For systems
without the alarm option, only two channels are used and the
third must be "plugged" with an attached rubber plug seal. See
Figure 7 [right]. If the alarm cord is present, all three channels will
be used. All rubber cover gaskets are permanently attached and
do not require replacement.

Figure 8. QuickTree Example Settings
When servicing the QuickTree, place the switch cord into the
trough or channel and then slip the stainless steel rod through the
clamp. Tighten the screw with a Phillips screwdriver, being careful
not to overtighten. Flats have been stamped on the rod to
designate float position, and the screw should be tightened onto
the flat. The tether length is the amount of cord between the
clamp and float.
1100-Series Access Cover
The 1100-Series cover contains access to the float and alarm cord
entry/exit seals. Refer to Figure 4 for these locations.
Electrical Service and Operation
RISK OF ELECTRIC SHOCK
WARNING
 Always disconnect pump(s) from power source(s) before
handling or making any adjustments to either the pump(s),
the pump system, or the control panel.
 All installation and maintenance of pumps, controls,
protection devices, and general wiring shall be done by
qualified personnel.
 Do not remove cord and strain relief, and do not connect
conduit to pump.
 Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
 Do not handle or unplug the pump with wet hands, when
standing on damp surface, or in water unless wearing
Personal Protective Equipment.
 Do not lift or carry a pump or a float assembly by its power
cord. This will damage the power cord, and could expose the
electrically live wires inside the power cord.
 The electrical power supply shall be located within the length
limitations of the pump power cord, and for below grade
installations, it shall be at least 4 ft (1.22 m) above floor level.
