3 ml) into the tubing and reconnect it to the
Tee.
NOTE: Now is the convenient time to
change the In-Line Activated Carbon Post
Filter.
• Slowly open the Feed Water Ball Valve.
When water begins dripping out of the
Dispensing Faucet, in the following order,
close the Faucet and then open the Holding
Tank Valve.
• Do not open the Faucet for at least 5 hours.
• Discard the first three full tanks of water
produced, they will contain chlorine.
5. Slowly open the Feed Water Ball Valve.
6. When water begins dripping out of the
Faucet, in the following order, close the
Faucet and open the Holding Tank
Valve. When the Faucet is first opened,
expect air and carbon fines (very fine
black powder), from the new Post Filter
to be rinsed out. This is normal for the
first tank of water.
C. Changing the In-Line Activated Carbon
Post Filter
1. Close the Feed Water Ball Valve by turning
fully clockwise.
2. Close the Holding Tank Valve and then
open the Dispensing Faucet to release the
pressure.
3. Remove the In-Line Activated Carbon Post
Filter. Disconnect the used Post Filter by
pressing in the connector's collar and at the
same time pulling the tube out of the fitting.
Unscrew the fittings on the In-Line, re-
Teflon tape them and install them on the
new Post Filter. Do not over tighten the
fittings.
4. Firmly reconnect the polytubes to the new
Post Filter. (Refer to Fig. 5 below.)
TECHNICAL DATA
A. Water Quality
Water quality is normally measured with a
special meter that measures the water's
ability to conduct electricity. The more
dissolved solids in the water, the higher the
conductivity. The results are usually
reported in Parts per Million (ppm) or
Milligrams per Liter (mg/l) of Total
Dissolved Solids (TDS). (Although
technically they are not exactly equal, in
most discussions ppm = mg/l).
Reverse Osmosis Membranes are rated by
the amount of dissolved solids that are
rejected. This rating is a ration of the TDS in
the feed water to the TDS in the product
water and is reported as Percent
Rejection. If the feed water contained 100
ppm of TDS and the product water
contained 10 ppm of TDS, 90 ppm have
been rejected and the reject ration is 90%.
Percent Rejection =
Feed TDS – Product TDS
Feed TDS
EXAMPLE: Feed water is 500 ppm TDS
and the product water is 75 ppm TDS.
Percent Rejection = 500 – 75 x 100%
500
Percent Rejection = 0.85 x 100% or 85%
