For adequate separator performance, the PEP ISC Separator system should be
installed no more than 5 feet above or 8 feet below the sump, water basin, or tower
water level.
Note: When the separator is installed above basin level, a check valve must be
installed in the lowest point of the pump suction line (below water level).
Piping and Valves – The PEP ICS Separator inlet is located on the side, near the top.
The separator outlet is located on the top. On 3” and smaller units, the purge
connection is located on the side, near the bottom. On 4” and larger units, the
purge connection is located on the bottom. The ½” and ¾” models have threaded
npt
nipples for connection to the inlet and outlet. All larger models have 150 lb. Raised
face flange connections.
The separator outlet piping should be plumbed to merge with the flow in the piping
system, not against it. Pipe size must be the same as the inlet and outlet separator
fittings to maintain proper flow. PEP will furnish typical installation drawings upon
request.
Connecting the drain line: To assure proper collected solids drainage, it is important
to match the drainpipe diameter with the diameter of the drain fitting on the ICS
Separator. Refer to the dimension table on the drawing in this manual (Purge Outlet
“B”) for the drain size of your particular ICS Separator.
Maintenance / Purging:
The ICS Separator requires periodic purging. Otherwise, accumulation of separated
solids will overfill the collection chamber and system performance will be diminished.
To assure sufficient purge pressure, there should be a minimum 5 psig at the
separator outlet. Slope the purge line continuously downward to assure complete
drainage. Three purge options are available:
1.
Manual purge: A valve on the collection chamber is opened by hand
periodically to purge solids from the chamber (standard on all ICS Separators).
2.
Automatic purge: PEP offers a motorized ball valve that will automatically
open the purge drain at a field selectable time interval. Once every 4 hours is
typical. The purge duration is also field selectable. The ICS Separator is
continuously on line, even during the purge cycle.
