Installation Checklist; What The Reverse Osmosis System Does - GE Smart Water PNRV18ZWH01 Installation Instructions Manual

PRESSURE TESTING THE SYSTEM
—DO THE SANITIZING PROCEDURE BEFORE PRESSURE
TESTING—INSTALLATION CHECKLIST
1. Open the water supply valve to the Reverse Osmosis system and
open the storage tank shutoff valve.
2. Check all connections for LEAKS.
3. In about 4 hours, pressure will build in the Reverse Osmosis
system. Carefully recheck all fittings and connections for water
leaks. Correct leaks if any are found.
4. Fill sink(s) 1/2 full of tap water and drain, checking drain
plumbing for leaks.
PURGING THE SYSTEM
1. Wait about 4 hours for the storage tank to fill.
2. Open the RO faucet until the tank is empty and flow stops.
3. Close the RO faucet and repeat these steps three more times.
The system is ready to make product water for use.
WARNING: Initially, the Reverse Osmosis cartridge
contains a food grade preservative that has to be purged
from the system before first use or whenever Reverse
Osmosis cartridge is replaced. The preservative will give
product water an unpleasant taste and odor.

INSTALLATION CHECKLIST

1. Are all tubing connections tightened? Do they run between the
points shown? No leaks!
2. Is the faucet base leadwire connected to the electronics box
leadwire?
3. Is the battery holder connected to the electronics box and are
the batteries installed in the holder correctly?
4. Did you use drain option B, C or D? Make sure the 3 ⁄ 8 " drain
tubing, from the faucet to the drain point, is without loops,
dips, or low-spots.
5. Is the tank shutoff valve in the open position?
6. Is the water supply shutoff valve open?
7. Did you sanitize and purge the system?

WHAT THE REVERSE OSMOSIS SYSTEM DOES

Reverse Osmosis removes Total Dissolved Solids (TDS) and
organic matter from water by diffusing it through a special
membrane. The membrane separates minerals and impurities
from the water and they are flushed to the drain. High quality
product water goes directly to the drinking water faucet or to the
storage tank. The system makes a good supply of drinking water
each day (see Product Specifications ). How much it makes depends
on the feed water supply pressure, temperature, and quality.
The system includes an electronic faucet assembly with an
integrated testing feature. When water is taken from the faucet,
a flashing green indicator light means TDS removal is within
specified limits and that water quality is good.
The prefilter and postfilter are replaceable cartridges. The carbon
prefilter removes chlorine while also filtering sediments. The
postfilter removes any other undesirable tastes and odors before
you use the water.
THE GE ELECTRONIC MONITOR SYSTEM
Indicator lights on the faucet base show Reverse Osmosis
performance when the faucet is open to dispense water.
Flashing Green Light—The Reverse Osmosis system is providing
high quality drinking water.
NOTE: If the Reverse Osmosis system is connected to the
refrigerator, this light will also flash when the icemaker or
dispenser is in use.
The green light may stop flashing when the supply of Reverse
Osmosis water is nearly gone and flow from the RO water faucet
decreases. This is a normal condition.
Flashing Amber "FILT" Light—The prefilter and postfilter cartridges
need replacing. This occurs after 6 months or 900 gallons of
product water use, whichever occurs first. Also, replace the 4 "AA"
alkaline batteries in the electronics box. Good batteries are needed
to ensure correct indicator light operation. Weak batteries may
give a false "RO" light indication. Changing the batteries resets the
6 month or 900 gallon period.
Flashing Amber "RO" Light—The Reverse Osmosis cartridge is no
longer removing at least 75% of the Total Dissolved Solids (TDS)
from the supply water. The Reverse Osmosis cartridge, flow
control, and screen need replacing.
NOTE: Disregard initial or short periods (a few seconds) of the
flashing "RO" light. Long periods of limited or no use can cause
the TDS levels to temporarily change.
