STEPS

With the RO machine running, open the Clean-In-Place (CIP) permeate valve. After this

for a few minutes to ensure the tank is rinsed thoroughly. After a minute or so, close the

CIP tank drain valve. The CIP tank should begin to fill with RO permeate. When the CIP

tank has filled to the indicated full line, turn the ON/OFF switch on the RO machine to the

OFF position.

While the machine is OFF, open the CIP inlet valve. Divert the permeate and concentrate

streams to the cleaning container for recirculation. Ensure that the pre-filter is clean. A

CIP pump (supplied with DLX models only) is recommended to supply feed pressure into
