Congratulatlons on your purchase of a Purwater Drinking
Water System. This system will reducethe concentration
of many dissolved solids (i.e., Sodium, Calcium, Chloride,
etc.) in your drinking water.
When properly installed on a SOFT, IRON-FREE water
supply, this system will provide years of trouble-free
service with only periodic maintenance.
READ THE INSTRUCTIONS THOROUGHLY BEFORE
INSTALLING THE SYSTEM.
IMPORTANI This system should NOT be used to make
non-potable watersafe to drink. lt should be installed only
on potable water supplies.
DESCRIPTION AND OPERATION OF THE SYSTEM:
The Purwater Drinkinq Water Svstem consists of five
major components:
(1) The SYSTEM ASSEMBLY which contains the
Membrane Module and pre- and post{ilters.
(2) The FAUCET which can be conveniently mounted
on the sink next to your everyday tap or on the
counter top adjacent to the sink.
(3) The PRODUCT WATER STORAGE TANK which
stores the product water unlil you are ready to use
it,
(4) The DRAIN LINE AIR-GAP built into the faucet,
prevents any possibility of back-siphoning of drain
water into the drinking water system and may be
required by local plumbing codes.

(5) The AUTOMATIC SHUT-OFF, which terminates
flowto drain when Product Water Storaqe Tank is
f ull.
The membrane is a Thin-Film Composite (TFC). This
system includes an activated carbon pre-filter which al-
lows it to be used on both chlorinated and non-chlorinated
water supplies with a pH between 3 and 11 and a TDS of
less than 1800 ppm. lf the system is installed on chlori-
nated water, the activated carbon pre-filter should be
changed approximately once per year, depending on
incoming water quality. Failure to regularly change the
pre{ilter, may result in damage to the membrane.
FEED WATER:
The main contaminants (and recommended limits)which
can adversely affect the life and performance of this
drinking water system are shown below:
Hardness
lron (Fe)
Managanese (Mn)
. 1.0 gpg
< 0.1 ppm
< 0.05 ppm
There are other waler characteristics that pertain to the
quality of the f eed water which will affect the pedormance
of the system; your dealer can determine their affects prior
to installing a Purwater Drinking Water System and sug-
gest any beneficial pretreatment.

INSTALLATION:
Water which has been treated with a reverse osmosis
system can be aggressive, therefore consider this when
choosing the material of construction of the treated water
distribution lines. (4)
Figure 1 shows the tubing connections necessary.
The system housing can be mounted on wall or side
of cabinet using appropriate fasteners.

drain line flow control. Tubing should be cut to
keep drain line as short as possible.
An adapter is included with the drinking water system
and must be installed to provide feed water (Figure 3).

CAUTION: DO NOT open cold watershut off valves
until ALL drinking water system tubing connections
have been completed. Cut the feed line and install
the sh ut-off valve provided. Make sure t ubing is f ully
inserted, failure to do so, will result in a leak.

NOTE: Attaching the drain line to the sink drain pipe
directly below a garbage disposal may cause the drinking
water system drain lo become plugged resulting in a
malfunction of the air-gaP.
b. lnstall the drain adapter fitting. (Figure 4). Hole
in drain adapter must line up with hole just drilled
in drain pipe.
c. Connect 3/8" tubing (provided) to large barbed
fitting valve stem on air-gap faucet. Cut and
connect other end of tubing to drain adapter f itting.
Length of tubing should be as shott as possible to
eliminate any sagging in the line.
(6) Installshut-off valve on side of R.O. storage tank.
(7) Attach yellow tubing to PRODUCT WATER STOR-
AGE TANK. Fully inserl tubing into shut-off valve
approximately 112" , tug on tubing to make sure tubing
is installed properlY.
(8) Make sure all tubing connections have been com-
pleted and then open cold water shut off valve. Check
for leaks and correct as necessarv.
ICE-MAKER CONNECTION:
This system may be connected directly to an ice-maker by
installing a union teeand shut-off valve ( provided) any-
where in the producl water line between the post{ilter and
the product water faucet. However, the final connection
should not be made or the valve not opened until after
performing the drain to waste procedure described in the
" Post I nstallation" section below.
POST INSTALLATION:
We recommend that you not use the water from the
drinking water system for the tvst 72 hours after installa-
tion and that you drain the system before retiring each
night for the f irst three days. Be sure to close the faucet
handle when the water stops flowing after 2-3 minutes.
The proper f unctioning of the equipment should be deter-
mined, prior to using the water for consumption. (Ask the
dealer how this is to be done.)
Because the system is new and has many plastic compo-
nents, you may experience some taste distorlion if this
drain to waste procedure is not followed. You may also
notice a cloudiness or fine black particles in the water
during this time, this is simply fines from the Taste-XrM
carbon filter and should be gone after the flushing period.
Your newly installed syslem can provide approximately
35-50 GPD, with 80-95+% rejection of dissolved solids,
depending on your water supply pressure. Reduced
quantity and quality can be expected if source water
supply pressure is low.
Air may occasionally accumulate in your storage tank,
causing the water you draw to appear cloudy. This cloudy
or milky appearance will disappear if you let the water
stand for a few minutes. This is not a sign of poor quality,
it is more often a sign of lack of use. lf you have this air
problem, drain your tank for 2 or 3 days like you did when
the system was first installed. The more you use your
drinking water system, the better it will operate, therefore,
f ind new uses for your R. O. water. Besides using it for all
of your cooking and drinking needs, you may also use il to
make ice cubes and water your house plants and pets.
You should use at least 2 gallons daily; if not, please drain
your system at least once a week, following the same
procedure as when the system was installed.
The drinking water system requires little maintenace,
however, periodic servicing of both the pre- and post-
filters will be required. Every six (6) months replace the
pre- and post{ilters.
Maintenance of the R. O. membrane module is usually
performed when the quality of the product water falls
below the desired rejection level of dissolved solids in your
water. Often the taste of the water will indicate the need
for maintenance. When the taste closely resembles the
regular tap water this indicates the need for service. The
water may also be checked periodically by the dealer to
determine when the module needs replaced.
Module replacement will generally be necessary by the
4th year of service; however, some systems may require
module replacement in the 2nd or 3rd years, depending on
water quality and usage habits.
