be recirculated for approximately 15 minutes or until the solution temperature reaches a
minimum of 85°F (29°C). Do not allow the cleaning temperature to exceed 110°F (43°C).
Highlight the CIP and RO System Selectors and select the OFF mode and allow the membranes
to soak in the solution for approximately 10 minutes. 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.
Do not operate the machine below the designated pressure without
approval from GE Water & Process Technologies. Operation below the
stated pressure may be detrimental to the pump.
Caution!
For ECN model only:
4. The ECN model does not include a CIP pump. You will need to install a CIP pump, a CIP
pump motor starter with a manual start/stop switch, plumb a CIP recirculation line back to the
CIP tank, a CIP recirculation hand valve, and a CIP recirculation pressure gage located after the
CIP pump but before the CIP recirculation hand valve in order to have the necessary
equipment to perform the cleaning process.
Connect the CIP pump discharge plumbing to the Victaulic fitting on the CIP inlet just upstream
of the RO pre filter. Connect CIP concentrate and permeate hoses from the RO to the CIP tank
(supplied by others). Open the CIP recirculation valve so as to create 15 psig back pressure to
the CIP pump. Turn on the CIP pump and recirculate the cleaning solution in the CIP tank for 5
minutes.
Open the CIP hand valve to the RO inlet line. Turn the panel two-position power switch to on
and recirculate the cleaning solution for 15 minutes or until the solution temperature reaches
100°F (38°C).
Do not exceed 110°F (43°C).
The membrane elements can only handle
temperatures in excess of 85°F (29°C) for short periods of time. If the cleaning solution
temperature rises too quickly then use a heat exchanger to control high temperature swings.
Turn off the RO high pressure pump by turning the panel two-position power switch to OFF
and turn off the CIP pump. Allow the RO to soak for 10 minutes.
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. Highlight to RO system and select
MANUAL mode on the AccuTrak® (DLX model) or turn the panel two-position power switch to
ON and flush the RO machine for one hour. The detergent is sufficiently flushed when the
permeate conductivity is restored to nearly its previous level.
