Long Term Storage - Liberty Pumps ProVore PRG101A Manuel D'installation

STORAGE BEFORE USE
Liberty pumps are shipped from the factory ready for installation and use. They should be held in storage if the
pump station is not complete. If storage is necessary, the pump should remain in its shipping container. It should
be stored in a warehouse or storage shed that has a clean, dry temperature-stable area where the pump and its
container should be covered to protect it from water, dirt, dust, etc. The ends of the cables - (plugs) must be
protected against moisture.

LONG TERM STORAGE

1.
If it is necessary to store a pump for a long period of time, it should be stored indoors in a clean, dry
temperature-stable environment. The pump should be covered to protect it from dust, dirt and water. The
plug end of the cable must be protected against moisture.
2.
Do not allow the pump to freeze.
3.
Prior to installation, the pump motor should be rotated to ensure the seals and cutters are free spinning.
4.
Installed pumps which are idle for long periods of time should be manually operated through the breaker
panel once a month to lubricate the seals. Turn off the breaker, unplug the piggyback switch, and plug the
pump directly into the wall socket. Turn the breaker on for 30 seconds. Turn the breaker off, and then plug
the piggyback switch back in.
4. x The Basin
The basin required for both effluent and sewage applications must be sealed and vented to meet health and
plumbing code requirements.
accordance with the National Electric Code, ANSI/NFPA 70. The diameter should be a minimum of 18" and the
depth a minimum of 24". (These are minimum requirements. A larger basin may be required in both effluent and
sewage applications depending on local codes and the number of fixture units entering the system. Check with the
local authorities or contact Liberty Pumps if you are unsure of the proper basin size.) Installation should be at a
sufficient depth to ensure that all plumbing is below the frost line. If this is not feasible, remove the check valve and
size the basin and/or adjust pump differential to accommodate the additional backflow volume.
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.
B. Inlet Connection & 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.
Liberty P380, & P680: The Liberty Pro Series basins have a 4" inlet molded to the side of the tank. This inlet

C. 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.
AT NO TIME SHOULD THE PUMP BE STORED WITHIN AN INCOMPLETE WET PIT. THE PUMP
SHOULD NOT BE PLACED INTO THE PIT UNTIL IT CAN BE FULLY OPERATED.
These pumps are not to be installed in locations classified as hazardous in
is sized to accept a 4" no-hub type coupling. Connect the gravity drainage line from
the fixtures to this hub.
Other Liberty basins provide a 4" caulking hub or pipe grommet inlet. Hubs utilize
caulking material or rubber donuts; grommets are a simple slip-fit.
gravity drainage line from the fixtures to this opening. (Other inlet sizes available –
consult factory.)
Do not exert heavy pressure or run heavy equipment on the backfill material as this could cause
the tank to collapse.
