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 the water supply valve is closed
1
(turn clockwise) and the RO water faucet is
open. Drain system until water stops flowing.
Locate the plastic drain elbow, next to the
2
brass check valve tee.
Unscrew the compression nut.

Remove flow control with a clean knife
4
edge. Remove screen; a toothpick may be
needed.
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
1
tightened.
Turn on water supply by slowly opening the
2
water supply valve (turn counterclockwise)
to the Reverse Osmosis system. Carefully
check system for leaks.
Fill sink(s) 1/2 full of tap water and drain,
3
checking drain plumbing for leaks.
Wait approximately four hours for storage
4
tank to fill. At that time, carefully check all
fittings and tubing connections again for any
water leaks.
Water supply valve
If you are replacing the flow control and
5
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
6
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
7
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
8
cartridge, return to the Reverse Osmosis
Cartridge Replacement instructions.
Otherwise, open the water supply valve
(turn counterclockwise). Close the RO
water faucet.
Open the RO water faucet until the tank is
5
empty and flow stops.
After filling and emptying the storage tank
6
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 or
whenever the Reverse osmosis cartridge is
replaced. The preservative will give product
water an unpleasant taste and odor.
