Installing Clean-In-Place Valves

NOTE: Clean-In-Place (CIP) valves are not included with the machine. The CIP
valves must be purchased and installed by the customer.
When installing the CIP valves, a three-way valve should be installed in the inlet feed
stream of the machine. The tees on the permeate and concentrate lines should be
installed with two-way valves. All valves should be installed in a manner that will
allow circulation of the cleaning chemicals through the machine and back to the CIP
container during cleaning.
CAUTION:
WARNING:
2.4

Concentrate Outlet Connections

Connect proper size drain line to the concentrate outlet (Table 2.1) and run to an open
drain. The drain capacity needs to be large enough to properly drain the feed water
flow of the RO. The maximum concentrate back pressure is 60 psig (4.1 barg) for the
RO machine.
CAUTION:
2.5

Feed Water Requirements

The following feed water requirements must be met before installing your new E4
machine to ensure quality permeate and extended membrane element life. Refer to
Table 2.2 (E-Series Feed Water Requirements) for feed water information.
If CIP valves are not installed when machine is installed, provisions
must be made to bypass permeate and concentrate to drain for flush-
ing at start-up.
NEVER OPERATE THE MACHINE WITH THE CONCENTRATE OR PER-
MEATE LINES BLOCKED. SEVERE DAMAGE TO THE UNIT MAY RESULT.
Operation above 60 psig (4.1 barg) concentrate back pressure may
damage the machine.
