Flow Control and Screen
The flow control regulates the flow of water
through the Reverse Osmosis cartridge at the
required rate so high quality product water is
produced.
When servicing the Reverse Osmosis cartridge,
check the flow control and tubing, to make sure
the tube and surrounding surfaces are clean and
unrestricted. A small, cone-shaped screen is
located in front of the flow control to help keep it
clean. If the flow control is plugged with foreign
particles, the Reverse Osmosis cartridge cannot
discharge minerals and impurities to the drain. If
this happens, it will only take a short time for the
system to plug.
Make sure tank shutoff valve is closed, water
supply valve is closed (turn clockwise), and the
RO water faucet is open. Drain system until
water stops flowing.
Locate the plastic drain elbow, next to the
brass check valve tee.
Unscrew the compression nut.
Remove flow control with a clean knife edge.
Remove screen; a toothpick may be needed.
If you are replacing the flow control and
screen,
discard them. If you are checking the
flow control,
screen and tubing for blockage,
clean these parts of any debris. Do not blow
through the flow control, it will contaminate
the part.
Replace the screen by placing the cone end
into the elbow cap and carefully push it in.
CAUTION:
Do not force in further after you feel
resistance. Visually check to be sure it is
properly positioned.
Install flow control and tighten compression
nut by hand, then another 1⁄4 turn with
pliers.
DO NOT OVERTIGHTEN AND DISTORT OR
CRUSH THE TUBING AND FLOW CONTROL.
If you are replacing the Reverse Osmosis
cartridge, return to the
Reverse Osmosis
Cartridge Replacement
instructions. Otherwise,
open the tank valve and the water supply valve
(turn counterclockwise). Close the RO water
faucet.

Purging the Reverse Osmosis System
The Reverse Osmosis system
MUST BE PURGED
AFTER INSTALLATION
and
WHEN THE REVERSE
OSMOSIS CARTRIDGE IS REPLACED.
Make sure all tubing connections are
tightened.
Make sure the tank shutoff valve is open.
Turn
on the water supply by slowly opening
the water supply valve (turn counterclockwise)
to the Reverse Osmosis system. Carefully
check system for leaks.
Wait approximately four hours for storage
tank
to fill.
At that time,
carefully check all
fittings and tubing connections again for any
water leaks.
Open the RO water faucet until the tank is
empty and flow stops.
After filling and emptying the storage tank
four times, the system is ready to make
product water for your use.
WARNING: The Reverse Osmosis cartridge
contains a food grade preservative that
should be purged from the system before
use. The preservative will give product water
an unpleasant taste and odor.
