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 temper-
atures 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 approximate-
ly 20 minutes.
WARNING: DO NOT LEAVE THE CLEANING STRENGTH SOLU-
TION IN THE MACHINE FOR A PERIOD LONGER THAN
ONE HOUR. THE CLEANING SOLUTION MAY DAM-
AGE 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.
4.5 Draining 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.
