Liberty Pumps Pro680 Serie Manual De Instalación página 4

Introduction
Before installation, read the following instructions carefully. Each
pump is individually factory tested to ensure proper performance.
Closely following these instructions will eliminate potential
operating problems, assuring years of trouble-free service.

ProVore grinder systems easily handle solids and sewage
waste found in typical residential applications. Their unique cutter
system grinds difficult wastes and then pumps it through a 1-1/2"
or 2" discharge line. 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®. Pump and alarm floats are pre-set on the
QuickTree system at proper operating levels. Do not adjust floats.
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.
Was current system sized by a professional? Minimum fluid flows
are required in sewage applications. Consult Liberty Pumps for
proper pump sizing prior to installation.
In-Ground Installation of Basins
A. Excavation: Excavate the hole as small as possible, with a
minimum recommended 8" diametrical clearance around the
tank. Never place the basin directly in contact with rocks or
other sharp objects. Place only fine, 1/8" to 3/4" pea gravel or
1/8" to 1/2" washed, crushed stone as bedding between the
basin and the hole walls. Do not use sand or native soil as
backfill. Properly compact underneath the basin to provide
a solid, level base that can support the weight of the filled
basin. It is recommended that the top lip of the basin be level
with the finished floor.
B. Initial Backfill: Only fine, 1/8" to 3/4" pea gravel or 1/8" to
1/2" washed, crushed stone should be used around the
bottom of the basin to hold it in place. Do not use sand or
native soil as backfill. Make the inlet connection as required
for particular basin.
C. Inlet Connection: Pro-Series basins have a 4" inlet molded
to the side of the tank. This inlet is sized to accept a 4"
no-hub type coupling. 1100-series basins use a hub with a 4"
seal for inlet connection.
Connect the gravity drainage line from the fixtures to this
hub.

be kept out of the backfill material. Only fine, 1/4" to 3/4" pea
gravel, or 1/8" to 1/2" washed, crushed stone is
recommended. Do not use sand or native soil as backfill.
Mound the backfill slightly and allow for natural settling.
