Take the short white tube connected to the “IN” side of the 4 way auto shut-off valve (ASV) on the top
of the unit and insert it into the elbow adaptor on the “OUTPUT” (right side) of the pre-filters. (Fig. 11)
Remember to insert the tubing firmly. Next, take the short white line connected to the “OUT” side of
the 4 way auto shut-off valve (ASV) on the top of the unit and insert it into the elbow adaptor on the
cap of the R.O. Membrane housing (Fig 11).
These two white tubes complete the connection between the pre-filters and the R.O. Membrane.
7.0 Setting the Flow Restriction Ratios of your System
Using the same blue tubing used to flush the pre-filters, insert one end of the blue tubing into the E–Z
Flush Flow Restrictor (Fig 12). After you have inserted the blue tubing into the E–Z Flush Flow Restric-
tor, insert the other end of the blue tubing into your kitchen sink. The water that will flow through
your E-Z Flush Flow Restrictor is referred to as “BRINE” water and will discharge into your drain washing
away the harmful particulates removed by the R.O Membrane.
Next, get a bowl or a bucket and place it under the short piece of blue tubing that is coming out of the
auto shut-off valve (ASV). The water that will flow out of the short piece of blue tubing that is com-
ing out of the auto shut-off valve (ASV) is the purified water produced by the R.O. Membrane and is
referred to as “PERMEATE” water.
Now, turn the dial on top of the E–Z Flush Flow Restrictor clockwise (Right), entirely closing the valve
of the E–Z Flush Flow Restrictor and then turn the Manual Shut-Off Valve (Fig.12) found on the feed
water supply line of your system to its “ON” Position. Within a moment PERMEATE water will begin to
flow out of the short blue piece of tubing coming out of the Auto Shut Off Valve (ASV), at the rate of a
very fast drip to a slow trickle. Air inside the R.O. Membrane will be forced out causing the fast drip or
slow trickle to sputter with the air escaping. Wait 2-3 minutes for the air to fully purge so that a steady
output is achieved from the R.O. Membrane.
Next, carefully open the dial on-top of the E-Z flush Flow restrictor counter clockwise (left) VERY SLOW-
LY until the amount of BRINE water flowing through the E-Z Flush Flow Restrictor is flowing THREE
TIMES FASTER than that of the PERMEATE water flow coming out of the RO Membrane. In this way
