Flush Mode Setup - Culligan G1 Series Installation, Operation And Service Instructions

At shutdown, the pump turns off and SV1 closes. Then fast flush solenoid valve SV2 and permeate valve SV3 open for a
programmed number of minutes. During this time, RO product water stored either in an elevated atmospheric tank or in a
pressurized storage tank floods through the pump and the feed side of the membrane, and then SV2 and SV3 close. This
process provides RO-quality water during shutdown on both sides of the membrane to keep the membrane clean. This
process also ensures that the RO will provide high quality product water the next time the pump is turned on.
NOTE Quality Flush and Permeate Flush are mutually exclusive optional features.

Any time that a Flush is actually taking place while the system state is RUNNING, the system will ignore the following er-
ror limits: delivered product TDS high, %recovery low, %recovery high, %reject low, membrane pressure drop, pump feed
pressure low. Once the flush ends, the error checking will resume. If the inlet pressure switch reports LOW pressure for
at least XX (XX is programmable at 1-30 seconds, at the main menu/setup/accessories/switch inputs menu) continuous
seconds, even if this is during or even partially during a flush time, the system will still recognize this instance as an error
condition, and it will begin the LOW PRESSURE process.
