system technology. The QuickTree
both pump activation and alarm (if equipped) are mounted on a stainless steel tree (rod), separate from the pump. There is no need to

2. The Basin

The Pro-Series Systems features 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, 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.
In Ground Installation of Pro-Series 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 your basin.
C. Inlet Connection: The Liberty 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. Connect the gravity drainage line from the fixtures to this hub.
D. Final Backfill: Large rocks, clods, and foreign objects should 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. Provide access to the basin cover for maintenance and service.
Do not exert heavy pressure or run heavy equipment on the backfill material as this could cause the
tank to collapse.
