eratures. Temperature of the water supply to
the Home DrinkingWater System must be be-
twean 40OF(minimum) and 100OF(maximum).
See the specification table on page 17. DO
NOT INSTALL ON HOT WATER,
,Reed the other limits (oH, hardness, etc.) on
page 17 and be sure yourwater supply can-
forms. Please read WATER SUPPLY, page 4.
WHAT YOUR HOME DRINKING WATER SYSTEM WILL DO I
Your Home Drinking Water System is a REVERSE
OSMOSIS (RO) water treating unit. It uses
household water pressure to reverse a natural
physical process called Osmosis. Water, under
pressure, isforced through • eami-permeable mem-
brane where minerals and impurities are screen-
ed out and sent down the drain with the waste
water. These minerals and impurities am measured
as total dissolved solids (TDS).
The system includes replaceable pre and postfiiter
sediment-carbon cartridges. The prefilter removes
sand, dirt, rust particles and other sediments. Italso
takes ohlodne out of the feed water. The postfliter
removes any remaining tastes and/or odors just
before water istaken from the system faucet. The
storage area holds almost I gallon of RO product
water for your needs.
The undersink system connects to e house COLD
water pipe for a water supply. An automatic shutoff
valve prevents water waste when the storage area
is full and the faucet is closed.
The drinking water system gives you acontinuous
supply of sparkling clear, delicious water for ddnk-
Ing and cooking. Foods will look better and taste
better too. The system eliminates the neadto buy
bottled water, instead, It puts highqualitywater right
at your fingertips.
NOTE: A product data sheet is included, and also
available from Seam. The data sheet listswhat this
RO system will remove (or reduce) from the water.
ELECTRONIC MONITOR
The electronic model has 2 water quality eansure,
located in the electronicbox. Indicator lightson the
faucet base work with the sensors, or probes, to
show you when water quality isgood, and when the
system needs servicing.
As you take water from the RO faucet, a flashing
green light means the system is g'Mng you high
quality RO water. Over 8 bedod of time, the RO
membrane, prefiiter cartddge and postfilter begin
to _efficiency. Rashing amber lightS(see pages
12, 13 and 14) tell youwhen to service the RO mem-
brane end filters.

•WHERE TO MOUNT THE RO ASSEMBLY AND
LOCATE THE STORAGE TANK
The Home Ddnking Water System fits nicely under
the kitchen or bathroom sink. However, you can in-
stall it where most handy for you. You do need a
COLD water supply pipe and drain point within 6
feet. Where speoe islimited,you can lay it on a shelf
or floor. Locate the assembly so you can easily get
to It to change filters.
The RO System weighs about 40 Ibs. when foil of
water. Set It on the floor or other solid surface that
will hold this weight.

THINGS TO CHECK BEFORE YOU START TO INSTALL
REMOTE LOCATION -- You can install the RO
assembly or water supply saddle valve in another
place away from the RO faucet (please see page
16).
• REPLACING ANOTHER RO SYSTEM -- We
suggest you remove all parts ofanother RO system,
and use everything included with your new RO
system.
TOOLS AND MATERIALS YOU WILL NEED
•W16" and 112" open end wrenches.
II pliers and adju_able wrench.

HOW TO INSTALL YOUR HOME DRINKING WATER SYSTEM
STEP 1 -- INSTALL THE COLD WATER SUPPLY SADDLE VALVE (FIG. 2)
•Install this valve on the COLD water pipe to the
kitchen sink (FIG. 2).
•Thisvalve has a cuffing pinand will make itsown
holein copper or plasticpipe. To installon iron pipe,
you have to drill a 1/8" diameter hole for the cut-
ting pin.
DANGER (IF DRILLING PIPE): TO PROTECT
YOURSELF FROM SERIOUS INJURY OR FATAL
SHOCK, USE A HAND OR BATTERY POWERED
DRILL ONLY TO MAKE THE HOLE. DO.NOT USE
AN ELECTRIC DRILL.
•USE THE FOLLowING GUIDES TO INSTALL:
1. Close the house main water supply valve. Open
a high and low faucet in the house to drain water
from the pipes.
2. Looking at FIG. 2, if not already done, turn the
valve into clamp A and tighten. Turn the valve han-
dle all the way out.
NOTE: Ifyou have to drille 1/8Wdiameter hole, hold
the valve with clamp A up tothe pipe and mark the
spot to drill. BEFORE DRILLING, READ THE
DANGER NOTE ABOVE.
3. Place the seal on the inside of clamp A as shown.
Locate clamp A (tum handle in to align pin if pre-
ddlled hole) and clamp B on the pipe. Fasten in
place using 2 screws. Tighten each screw evenly,

but do not overtighten and crush the pipe.
4. Turn the valve handle inward to make a hole in
the copper or plastic pipe.
DO NOT TURN ON THE WATER SUPPLY AT THiS
TIME.
NOTE: BE SURE THE VALVE HANDLE PACKING
NUT IS TIGHT.
STEP 2 --- INSTALL THE DRAIN CLAMP (FIG. 3)
•The drain clamp fitsup to 1-3/4 _diameter drain
pipe.
•The best place to install the clamp is...
A. about 3" above the standing water level in the
sink p-trap (drawing A).
B. on the horizontal drain pipe run of a double bowl
sink (drawing B).

•Locate so drain tubing from the faucet (FIG. 7,
page 10) makes a straight run tothe clamp, without
any dips, loops, low spots, or kinks.
•You have to ddUa1/4'"diameter hole forthe sad-
dle clamp.
•Use the following guides:
1. Remove the paper backing from the gasket and
place the sticky side of the gasket into the recess-
ed area of the clamp bOdy. ""
2. Pla¢_ethe U-b01taround the drain pipe and slide
- the clamp body onto the bolt.
3. Turn the 2 wing nuts onto the U-bolt and tighten
snugly, BUT DO NOT OVERTIGHTEN AND
BREAK THE BODY OR CRUSH THE DRAIN PIPE.
NOTE: Be sure the pipe isclean and smoothwhere
the gasket will seal.
4. Using a hand or battery powered ll/;,'-dfill, make
a hole inthe drain pipe bygoingthrough the thread-
ed fitting on the clamp body (READ THE DANGER
