CLEANING PROCEDURE
STEPS
1. With the RO machine running, open the Clean-In-Place (CIP) permeate valve. After this
valve has been opened, close the permeate service valve. Permeate water will flow into
the CIP tank. Allow the water to run through the CIP tank and the CIP tank drain valve
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.
2. 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
the machine.
3. To circulate the cleaning solution through the machine with suction, remove the CIP plug.
Use a non-collapsible suction hose or pipe to feed the machine.
NOTE: Do not allow the machine pump to operate without concentrate flow. If pump
prime is lost while cleaning on suction, positive inlet pressure is required to
reprime. No air should be sucked into the inlet line during suction cleaning.
