Liberty Pumps Pro680 Series Installation Manual page 4

The ProVore 680-Series system is supplied with a 2" discharge
outlet. Do not increase this pipe size above 2" as adequate flow
rates may not be achieved for proper operation. Discharge sizes
may be reduced to 1-1/2" or 1-1/4". Consult Liberty Pumps for
proper pipe and system sizing.
Pro-Series systems come with an integral control system with
alarm and QuickTree® float system. Pump and alarm floats are
preset on the QuickTree system at proper operating levels. The
QuickTree system is located under a separate access cover for
ease of maintenance and service. Floats for both pump activation
and alarm are mounted on a stainless steel tree (rod), separate
from the pump. There is no need to disconnect plumbing or
remove the pump to inspect service or replace floats. QuickTree
floats are preset at the factory for optimum operating levels and
should not be adjusted.
Pro-Series systems also feature a clear disposable construction
cover designed to protect the system during rough-in and
masonry work. The protective cover should remain in place until
finish plumbing; however, it can be removed and reinstalled if
required. The cover is snapped into the threaded ports of the
discharge and vent. To remove the clear cover, simply pull
upward, disengaging it from the discharge and vent holes.
1100-Series systems (non-grinder types) feature a heavy-duty
basin with 4" inlet hub pre-assembled to basin. Floats are tethered
to a removable standpipe/access cover assembly. The cover is
equipped with a 2" or 3" discharge and 2" or 3" vent flange.
Was the current system sized by a professional? Minimum fluid
flows are required in sewage applications. Consult Liberty Pumps
for proper pump sizing prior to installation.
