Purging The Reverse Osmosis System - GE PNRV18ZBB01 Owner's Manual

About the reverse osmosis system.
The Faucet and Indicator Lights
Faucet and Electronics— The countertop faucet
dispenses filtered drinking water when opened.
It has a hand-operated, spring-loaded lever to
prevent waste. You can keep the faucet open by
pushing upward on the lever, until it locks against
the faucet spout.
To comply with plumbing codes, an air gap is built
into the faucet drain water connection.
The electronic faucet provides an integrated TDS
monitor. As water is taken from the faucet, the
indicator lights show how the Reverse Osmosis
system is operating to provide high quality
drinking water.
Flashing Green Light— The Reverse Osmosis system
is providing high quality drinking water.
If the Reverse Osmosis Filtration System Is Connected to Your Icemaker
Before you service the filter, change the filters, or purge the Filtration system, YOU MUST turn off the icemaker by raising the
feeler arm. Four hours after servicing your unit, lower the feeler arm to resume icemaking.
