Quicktree And 370/380-Series Access Cover - Liberty Pumps Pro370 Serie Manual De Instalación

F. Vent: On Pro370, 700, and vertical discharge Pro380-Series
models, a threaded 2" or 3" connection is provided on top of
the cover. The vent must be piped to the existing building
vent, or extended outside on its own standpipe.
On both side and vertical discharge systems, the vent size
must be in accordance with applicable codes, but not less
than the discharge size.
On Pro380SD (side discharge) models, venting is
accomplished through the inlet. See Figure 10 for Pro380SD
venting example through the inlet pipe as an alternative
solution.
Note: Pro-Series systems shipped with steel pipe option have
a rubber grommet seal on the discharge instead of female
NPT connections.

QuickTree and 370/380-Series Access Cover

Liberty Pumps Pro370 systems and vertical discharge 380-Series
systems feature QuickTree technology. Floats for both pump
activation and alarm (if equipped) are mounted on the QuickTree,
separate from the pump.
The QuickTree float system uses a stainless steel mounting rod
(tree) and specially designed cord clamping brackets to affix the
pump float and (optional) alarm float 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 float(s), 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. Vertical discharge systems feature a manual pump (with no
switch attached directly to the pump). Operation of the pump is
accomplished by the QuickTree system. Side discharge 380-Series
systems are equipped with an automatic pump.
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 motor, 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 11 [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 11 [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.
