NOTE: During flushing procedure, the machine must be running.
2. Allow the machine to operate with the concentrate valve open (Step 1) for 10 -
15 minutes.
3. After 10 - 15 minutes, return the concentrate valve to its previous setting, and
return to normal operation.
CAUTION: When opening the concentrate valve, never allow the machine’s
primary pressure to drop more than 10% below normal operating pressure.
4.1.2. Daily Flushing for the Deluxe Model
The DLX Model machine includes an Autoflush Timer Option. The Autoflush Timer
Option automatically flushes the machine at preset intervals.
4.2. Pre-filter Cartridge
A 1-micron pre-filter cartridge is factory installed to protect the membrane elements
and valves from particles, which may be in the feed water. To order replacements,
see the Spare Parts List.
A pressure drop across the filter of 8 psi (0.55 bar) or more during operation indicates
that the pre-filters cartridge(s) need changing. Use only GE approved filters rated for 5
microns or less. Do not attempt to clean used filters.
IMPORTANT NOTE: Failure to change the pre-filter cartridge according to these
requirements will void machine warranty.
4.3. Membrane Element Cleaning
GE recommends that you clean your RO every quarter, depending on the quality of
your feed water. Cleaning of the membrane elements is vital because contaminants
can build up on the membrane element surfaces, reducing the permeate flow rate
and affecting the quality of the permeate.
4.3.1. Step Wise Cleaning
This RO machine and many others have a centrifugal pump on them. Centrifugal
pumps are not designed to draw water. They are designed to operate with flooded
suction only. The manufacturer recommends using a Clean-In-Place (CIP), or booster
pump, to provide water pressure and flow to the RO machine pump from the CIP
container.
