Operating & Maintenance Manual

GENERAL DESCRIPTION

PEP CL Series Industrial Water Filters are permanent media type units specifically
designed to remove suspended particulates from industrial and process water. CL filters
are suitable for both side-stream and in-line applications on pressurized systems. The
standard pressure rating for CL filter systems is 150 psig. Optional higher pressure
ratings and ASME coded vessels are available.

Filter Operation

Unfiltered system water is pumped through the CL filter inlet and over-drain assembly at
the top of the filter tank where it is distributed evenly over the media. Suspended
particles are entrapped within the filter media. The resulting filtered water then passes
from the vessel through the under-drain assembly at the bottom of the filter and is
returned to the system.
When trapped particles cause the pressure differential across the media bed to reach a
pre-determined pressure of approximately 16 psig, the valves are automatically or
manually repositioned and the media is backwashed with a rigorous scouring action for
approximately three minutes. The accumulated particulate exits the filter vessel via the
over drain assembly and flows to drain. After which, the valves are returned and
filtration continues.

Installation

Unpacking
Immediately upon receipt, the PEP CL filter should be checked thoroughly to ensure
that all required items have been received and the filter equipment is free of any
shipping damage prior to signing the bill of lading.
The filter model number appears on a nameplate located on the unit and should be
checked against the invoice/packing list.

Rigging

1. The PEP CL units should be lifted with a forklift or overhead crane. If these
units are lifted with an overhead crane, lifting straps must be located below
the filter skid and should not come in contact with filter components. For
non-skidded filters, use lifting lugs located at the top of the filter vessel.
2. All PEP water filters should be rigidly anchored to the floor or support steel by
means of anchor bolts. The CL has holes suitable for 3/4" anchor bolts.
