F. Vent: A 2" or 3" vent connection is provided on top of the
1100-Series unit. The P680-Series vent is in the tank. The vent
must be piped to the existing building vent, or extended
outside on its own standpipe.
The vent size should be in accordance with applicable codes,
but not less than the discharge size.

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. It is important that
cords from the pump motors and float switch, and optional alarm
float are properly 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 6 [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 6 [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.

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. 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. Floats are pre-set and system may contain three
or four floats based on selected options.
