Step B - Install RO Drain Under Sink
INTRODUCTION
A suitable drain point is needed for the drain water from
the Reverse Osmosis filter. You have two options:
• Install the Drain Adaptor included with your unit
As shown in Figures 7-9, the drain adaptor is
installed onto your sink’s drain pipe above the P-trap.
This is normally used for under sink installations.
• Use another existing drain in your home
As shown in Figures 10 and 11, the drain tube from
the RO filter runs directly to an open drain. This is
often used for remote location installations.
NOTE: An incorrectly connected drain point can
cause water to leak from the faucet’s air gap.
NOTE: Local code may restrict the type of drain
installation to use. Either drain installation type, if
permitted by code, may be used in under sink or
remote location installations. Consult a plumber if
you are not familiar with plumbing procedures.
INSTALL DRAIN ADAPTOR
(Under sink Installation)
The drain adaptor included with your RO system is
designed to fit around a standard 1-1/2” O.D. drain
pipe. In the following procedure, you will install the
drain adaptor above (upstream of) the P-trap. See Fig.
7 & 9. Be sure to comply with local plumbing codes.
NOTE: Before starting this procedure, inspect the
drain pipe under the sink for corrosion, and replace
if necessary, before continuing with installation.
1. Test fit the two halves of the drain adaptor onto the
sink drain pipe, about 6 inches above the P-trap
(See Fig. 8). Make sure that the Q. . fitting is
toward the direction of the RO faucet (See Fig. 9).
NOTE: Locate so that the drain tubing from the
Reverse Osmosis faucet will run straight to the
adaptor, with no dips, loops, or kinks.
2. Using the hole through the drain fitting as a guide,
mark the pipe where a 3/8” hole will be drilled (See
Fig. 8), and remove the drain adaptor from the pipe.
NOTE: Do not drill through the drain adaptor’s
.C. fitting, as this could damage the o-ring.
3. Drill a 3/8” dia. hole in the pipe and remove flash.
4. lean the sink tailpiece to assure a leak-tight fit.
5. Place the halves of the drain fitting back onto the
sink drain pipe. Use a pencil or similar pointed
object to align the Q. . fitting so that it is centered
on the hole you drilled.
6. Assemble the nuts and screws, as shown in Figure
9, and tighten both sides equally to secure the drain
adaptor halves onto the pipe. Do not overtighten.
7. Do not connect black tubing to the Q. . fitting at this
time. It is done after the RO faucet is installed.

INSTALL A REMOTE DRAIN POINT
AND AIR GAP (Remote Location)
Route the drain tubing to an existing drain in the house.
A floor drain, laundry tub, standpipe, sump, etc. are
suitable drain points. See Fig. 11. This type of drain is
the preferred over the p-trap drain adapter.
Always be sure to provide a 1-1/2” air gap between the
end of the hose and the drain point. This will prevent
water from backing up into the system.
NOTE: Check your local plumbing codes.
To install a remote drain point, complete the
following steps:
1. Locate the 1/4” red tubing on the Reverse Osmosis
filter assembly. See Fig. 10.
2. Determine if this length is long enough to reach the
drain point. Longer lengths of tubing (see parts list in
back of manual) may be needed.
3. If longer tubing is required, disconnect the 1/4” red
tubing and replace with an adequate length of tubing
to reach the drain point. Refer to Step F later in the
manual on how to disconnect and connect tubing.
NOTE: A flow control insert is located inside the
fitting that the drain tube connects to. See No. 12
on page 22. Leave this fitting in place.
4. Route the tubing to the drain point and secure at the
end with a bracket (not included). See Fig. 11.
Provide a 1-1/2” air gap between the end of the tube
and the drain. See Fig. 11.

Step F - Connect Tubes
HOW TO CUT AND CONNECT THE TUBES
Your Reverse Osmosis system includes push-in fittings
for quick tubing connection. Review the following
instructions before connecting the tubes in the next
step. Failure to follow these instructions may lead to
future leaks.
Cut tubes to length
1. Use a sharp cutter or knife to cut the end of tubing.
Always cut the tubing square. See Fig. 16.
2. Inspect the tube up to 1” from the end to be sure
there are no nicks, scratches or other rough spots. If
needed, cut the tubing again. See Fig. 16.
Connect tubes
1. Push tubing through collet, until it engages the o-
ring. See Fig. 17. ontinue pushing until the tube
bottoms out against the back of the fitting. See Fig.
18. Do not stop pushing when the tube engages the
o-ring. Failure to follow these instructions may lead
to future leaks. When a 1/4” tube is fully engaged,

Step G - Sanitize, Test and Purge System
SANITIZE THE SYSTEM
Sanitizing is recommended immediately after installa-
tion of the Reverse Osmosis system. It’s also recom-
mended after servicing inner parts. It is important that
the person installing or servicing the system have
clean hands while handling inner parts of the system.
omplete the following steps to sanitize the system.
See Fig. 22.
1. Make sure that the water supply to the Reverse
Osmosis system is off.
2. Open the Reverse Osmosis faucet. If the tank is not
already empty, allow the water to empty.
3. Locate the eyedropper included in the parts bag and
common household bleach.
4. Add 3 ml. of bleach into open end of yellow tubing.
Handle bleach according to bleach manufacturer’s
recommendations. See Fig. 22.
5. onnect yellow tubing to tank connector. See Figs.
13 and 22.
6. Sanitizing the system will be completed during the
pressure test and purging steps on the following
page.
NOTE: The bleach must be removed from the sys-
tem before drinking the water. See purging instruc-
tions on the next page.

PRESSURE TEST THE SYSTEM
NOTE: Complete the sanitizing procedures on the
preceding page before pressure testing.
To pressure test the system, complete the following
steps.
1. Open the water supply valve(s) that you closed
before installing the Reverse Osmosis system.
2. Purge air from the plumbing by opening the sink
faucet(s). lose faucet(s) when water runs smooth,
with no spurting.
3. Pressure will start to build in the RO system. In
about 2 hours check all fittings and connections.
heck for water leaks. Fix leaks if any are found. If
problems exist, refer to the troubleshooting chart or
call the toll free number below).
NOTE: When the system is first pressurized, water
may ''spurt'' from the faucet air gap hole until air is
expelled from the RO system.
Please review the following operating features
before using your Reverse Osmosis system:
NOTE: As with all other water system applications,
leaks may occur. Because the system pressure
builds slowly, leaks may not be immediately appar-
ent. Recheck for leaks 24 hours after purging the
system is complete.
PURGING THE SYSTEM
To purge the system, complete the following steps.
1. Open the Reverse Osmosis Faucet and let water
flow through the system for a 24 hour period. Water
flow will be a slow trickle at this time.
NOTE: Do not consume water from the RO sys-
tem until purging is complete.
2. lose the Reverse Osmosis faucet after the 24 hour
purging period is complete.
3. When the purging is finished, your Reverse
Osmosis system is ready for use.
You will not have filtered water immediately. It may
take several hours to fill the storage tank and create
maximum flow from the Reverse Osmosis faucet.
Water will run to the drain while the Reverse
Osmosis system is producing water, even if you are
not drawing water from the Reverse Osmosis faucet.
You may hear a small quantity of water going to the
drain at times when water is not being used. This is
normal. Water going to the drain will automatically
shut off when the storage tank is full.
Water Pressure from the Reverse Osmosis faucet will
be less than your standard faucet.

HOW YOUR REVERSE OSMOSIS SYSTEM
WOR S
Introduction: Your Reverse Osmosis (RO) Drinking
Water System uses your household water pressure to
force water through three filters. Impurities are filtered
out. Delicious tasting drinking water goes to the stor-
age tank-ready for your use. Impurities are sent down
the drain. The following paragraphs will explain in
detail how your Reverse Osmosis Drinking Water
System works.
Prefilter: Water from the cold supply pipe enters the
prefilter. See Fig. 24. The prefilter is a replaceable
sediment cartridge with activated carbon in its compo-
sition. The cartridge reduces taste, odor, sand, silt, dirt,
other sediments, and up to the amount of chlorine
shown in the specifications.
Reverse Osmosis Cartridge: Filtered water flows
from the prefilter to the Reverse Osmosis membrane
cartridge. See Fig. 24. The Reverse Osmosis cartridge
is a tightly wound special membrane. The membrane
reduces the dissolved solids and organic matter. High
quality product water (about one ounce per minute)
exits the Reverse Osmosis cartridge. The product
water flows to the storage tank, postfilter or Reverse
Osmosis faucet. Drain water, with the dissolved solids
and organic matter, is routed to the drain.
Storage Tank: The storage tank holds product water.
See Fig. 24. A diaphragm inside the tank holds water
pressurized to about half of supply water pressure
when the tank is full. This provides fast flow to the
Reverse Osmosis faucet. When the tank is empty of
water, the pressure at the air valve is 5 - 7 psi.
Postfilter: Water goes through the postfilter before
going to the Reverse Osmosis faucet. See Fig. 24.
The postfilter is an activated carbon type filter. Any
remaining tastes and odors are reduced from the prod-
uct water. lean, high quality drinking water is avail-
able at the faucet.
Reverse Osmosis Faucet: The sink or countertop
faucet has a hand operated knob to dispense drinking
water. See Fig. 24. An air-gap is built into the faucet
drain water connection to comply with plumbing codes.
Shutoff Assembly: The unit has an automatic shutoff
system to conserve water. When the storage tank has
filled to capacity, and the drinking water faucet is
closed, pressure closes the shutoff to stop flow to the
drain. After enough drinking water is used, pressure in
the system drops, and the shutoff opens to allow the
tank to be refilled. See Fig. 24.
Check Valve: A check valve is located in the Reverse
Osmosis manifold above the center cartridge. The
check valve prevents a backward flow of product water
from the storage tank to drain. A backward flow could
damage the Reverse Osmosis Membrane.
See Fig. 24.
Flow Control: Water flow to the drain is restricted by
the flow control. It maintains the desired flow rate to
obtain the highest quality drinking water. The flow con-
trol is located inside the fitting on the Reverse
Osmosis manifold drain port. See Fig. 24.

Water Flow Description
1. Water enters prefilter. Sand, silt and other sediments are reduced. hlorine is also reduced. See Fig. 24.
2. Water leaves prefilter and proceeds to the Reverse Osmosis artridge.
3. Water enters the Reverse Osmosis membrane. Dissolved solids are reduced.
4. Processed water leaves the Reverse Osmosis Membrane and flows to the storage tank.
5. Drain water with dissolved solids leaves the Reverse Osmosis membrane and flows to the drain.
6. Faucet is activated.
7. Processed water leaves the storage tank and flows to the postfilter, where it is filtered to ensure fresh taste.
8. Water flows to the Reverse Osmosis faucet.

Maintenance
PREFILTER / POSTFILTER MAINTENANCE
NOTE: It is recommended to replace the prefilter
and postfilter cartridges at least every 6 months of
product water use. Replace more often if they
begin to plug with sediment.
The prefilter and postfilter are replaceable sediment
cartridges with activated carbon in their composition.
See Fig. 25. You must periodically replace the prefilter
and postfilter cartridge. This will protect the RO mem-
brane from being destroyed by chlorine. It will also pre-
vent the filters from plugging with sediment.
You may notice a slower output of product water as
the prefilter and postfilter build up with sediment.
Replace the prefilter and postfilter cartridges when this
occurs.
RO MEMBRANE CARTRIDGE MAINTENANCE
The Reverse Osmosis cartridge is a tightly wound spe-
cial membrane. See Fig. 25. The membrane reduces
the dissolved solids and organic matter. The life of the
Reverse Osmosis membrane cartridge depends mostly
on the pH and hardness of the supply water (see
Specifications). artridge life is shorter with higher pH.
For example, if supply water pH is from 6.8 to 7.7, the
cartridge may last for well over one year. However,
cartridge life may be as short as 6 months if the pH is
as high as 8.5 to 10. Higher pH weakens the cartridge
membrane and causes pin-hole leaks. It's time to
replace the Reverse Osmosis membrane cartridge
when the production rate and/or quality of product
water drops. Product water may begin to taste differ-
ent, indicating solids and organics are passing through
the Reverse Osmosis membrane. See Reverse
Osmosis membrane cartridge replacement.
