HOW IT WORKS
Feed Water Valve:
This is the mechanism that connects the system to your cold water line under your sink. This device will
self pierce copper and plastic plumbing.
Sediment Filter:
As water passes through this filter, rust, sand, scale, and other large particles are reduced.
Carbon Filter:
After the sediment Filter, the water passes through a carbon filter where chlorine, taste, and odor are reduced.
Shut-Off Valve:
When the storage tank is full and no product water is being drawn from the faucet, this valve closes and
stops all flow of water through the system.
Reverse Osmosis Membrane:
After the water has been pre-filtered, it flows through the semipermeable spiral. Here, dissolved solids
are flushed to the drain, while the water that is able to pass through the membrane flows to the storage
tank. A CTA (Cellulose Triacetate) membrane is a paper byproduct membrane bonded to a synthetic layer.
Due to its cellulose composition, a CTA membrane requires chlorine in the water source to keep bacteria
from forming on it. A CTA membrane has a rejection rate between 85-94 percent. TFM (Thin Film
Membrane) membrane is made of a synthetic material. A TFM membrane does not require chlorine to be
in the water to protect it from bacteria. A TFM membrane has a rejection rate between 95-98 percent,
which is much higher than the CTA membrane.
Flow Restrictor:
This device allows the correct amount of reject water to flow over the membrane to help prolong its life
and to aid in high quality water production.
Drain Saddle Valve:
This connects to your drain plumbing and allows reject water flow to enter the drain system.
Storage Tank:
The storage tank holds 2.8 gallons of product water at 40 psi. A diaphragm inside the tank keeps the
water under pressure. The tank has an air pre-charge of 5-7 psi from the factory.
Polishing Filter:
Granular activated carbon or carbon block is the final treatment step of your product water. This process
enhances and clarifies water prior to delivery.
Faucet:
This sink-top or counter-top faucet dispenses the product water. It is hand operated and has two positions.
Pushing down delivers flow as needed, and lifting the lever delivers constant flow.
NOTE: YOU MAY HEAR A GURGLING NOISE FROM THE FAUCET OR FROM THE SINK. THIS IS
NORMAL, IT IS THE WATER GOING TO THE DRAIN. THE NOISE WILL STOP ONCE YOUR STORAGE TANK
IS FULL. FURTHER, IF YOUR UNIT IS EQUIPPED WITH ULTRA VIOLET DISINFECTION IT IS NORMAL FOR
THE FIRST FEW SECONDS OF WATER FLOW TO FEEL WARM. THIS IS DUE TO THE ENERGY EMITTED BY
THE UV LIGHT BEING ABSORBED BY THE WATER.
