4.Turn the CIP ON/OFF switch to the ON position and recirculate the cleaning solu- tion through the machine. The cleaning solution should be recycled for approxi- mately 15 minutes or until the solution temperature reaches 85°F (29°C). If heat rise occurs too quickly, larger volumes of cleaning solution or the use of a heat exchanger will slow the temperature rise. Turn the CIP OFF and allow it to soak for 10 minutes.
TLC MEMBRANE NOTE: It is best to clean at temperatures of 100°F - 110°F (38°C to 43°C), but lower temperatures will suffice. Do not allow the cleaning temperature to exceed 110°F (43°C). Allow the cleaning solution to recirculate for 10 minutes. Turn the machine off and allow the membrane elements to soak in the solution for approximately 20 minutes.
WARNING: DO NOT LEAVE THE CLEANING STRENGTH SOLUTION IN THE MACHINE FOR A PERIOD LONGER THAN ONE HOUR. THE CLEANING SOLUTION MAY DAMAGE THE MEMBRANE ELEMENTS AND/OR THE MACHINE DURING AN EXTENDED PERIOD OF CON- TACT.
5.To flush the detergent from the machine, close the CIP inlet valve and divert the permeate and concentrate to drain by opening the CIP drain valve. Operate the machine as described in the flushing section (Section 4.3, Flushing) for at least one hour. The detergent is sufficiently flushed when the permeate conductivity is restored to nearly its previous level.
6.To return the RO to service, open the permeate, concentrate valves so that flow is routed as intended in the service mode. Close the CIP permeate, CIP concentrate valves. The RO is now ready for operation.
4.5Draining Machine for Shipment
Prior to shipping or outside storage of a GE Osmonics E4H Machine, the system should be cleaned with the appropriate cleaner, flushed with water, and protected from biological attack with the appropriate solution for TLC membrane. The membrane element housings and piping lines of the machine must be completely drained. Any water remaining in the piping of a machine may freeze, causing damage to the piping, pump, membrane elements, etc. The party shipping or storing the machine is responsible for any damage resulting from freezing.
STEPS
1.Disconnect the inlet, concentrate and permeate outlets.
2.Drain all water from the cartridge filter housing.
