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:
If CIP valves are not installed when machine is installed, provisions must be
made to bypass permeate and concentrate to drain for flushing at start-up.
WARNING: NEVER OPERATE THE MACHINE WITH THE CONCENTRATE OR PERMEATE
LINES BLOCKED. SEVERE DAMAGE TO THE UNIT MAY RESULT.
2.4.
Concentrate Outlet Connections
Connect proper size drain line to the concentrate outlet (Table 2) 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:
Operation above 60 psig (4.1 barg) concentrate back pressure may
damage the machine.
CAUTION:
A vacuum breaker must be installed at the highest point along the
concentrate line. Failure to do so may cause a vacuum to form within this line after
shutdown. This may in turn cause numerous problems, including biological fouling,
water hammer, leaks from RO housing side-ports, and the siphoning of treatment
chemicals.
1.
Connect the concentrate line to the RO machine’s concentrate outlet. A
vacuum breaker must be installed at the highest point along the concentrate
line. This provides an atmospheric break upstream from where the flow enters
the drainage system. For systems which include multiple RO machines, install
check valves along each machine’s concentrate line prior to connecting the
lines to a common manifold.
