The basin – Liberty Pumps Pro370-Series User Manual

Pump and Alarm floats are pre-set on the

QuickTree®

system at proper operating levels. Do not adjust floats.

Was your system sized by a professional? Minimum fluid flows are required in sewage applications. Consult Factory for proper pump

sizing prior to installation.

QuickTree

Technology: The Pro-Series by Liberty Pumps features new QuickTree

float system technology. The QuickTree

system is located under a separate access cover for ease of maintenance and service. Floats for both pump activation and alarm (if

equipped) 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.

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

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.

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.

Inlet Connection: The Liberty P370 and P380 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.

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.
