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 8-10, 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 11 and 12, the drain tube from
the RO filter runs directly to an open drain. This is
often used for remote location installations.
N TE: An incorrectly connected drain point can
cause water to leak from the faucet’s air gap.
N TE: 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.
INSTA DRAIN ADAPTOR
(Under sink Installation)
The drain adaptor included with your RO system is
designed to fit around a standard 1-1/2” O. . drain
pipe. In the following procedure, you will install the
drain adaptor above (upstream of) the P-trap. See Fig.
8 & 10. Be sure to comply with local plumbing codes.
N TE: 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. 9). Make sure that the Q.C. fitting is
toward the direction of the RO faucet (See Fig. 10).
N TE: Locate so that the drain tubing from the
Reverse smosis 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. 9), and remove the drain adaptor from the pipe.
N TE: Do not drill through the drain adaptor’s
Q.C. fitting, as this could damage the o-ring.
3. rill a 3/8” dia. hole in the pipe and remove flash.
4. Clean 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.C. 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. o not overtighten.
7. o not connect black tubing to the Q.C. fitting at this
time. It is done after the RO faucet is installed.

Step B - Install RO Drain in Remote Location
INSTA A REMOTE DRAIN POINT AND
AIR GAP (Remote ocation)
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. 12. This type of
drain is the preferred over the p-trap drain adaptor.
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.
N TE: Check your local plumbing codes.
To install a remote drain point, complete the fol-
lowing steps:
1. Locate the 1/4” red tube and determine whether it is
long enough to reach from the Reverse Osmosis fil-
ter assembly to the drain point . See Fig. 11.
2. If longer tubing is required, see parts list in back of
manual and replace the red tube with an adequate
length 1/4” tubing.
3. Cut one end of the drain tube square. See Fig. 17.
4. Insert this tube all the way into the red collet fitting on
the Reverse Osmosis filter assembly. See Figs. 18, 19
& 22.
5. Pull on the tubing to be sure it is held firmly in the fit-
ting.
N TE: A flow control insert is located inside the
elbow fitting that the drain tube connects to.
Refer to Fig 27. Leave this fitting in place.
6. Route the tubing to the drain point and secure at the
end with a bracket (not included). See Fig. 12.
Provide a 1-1/2” air gap between the end of the tube
and the drain. See Fig. 12.

Step E - 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.
N TE: Tubing lengths should allow for the
removal of the assembly from the hanger wash-
ers for servicing. If tubing lengths are shortened
for neater appearance, it may be necessary to
keep the assembly on the hanger washers for
service.
Connect tubes
1. Push tubing through collet, until it engages the o-
ring. See Fig. 17. Continue pushing until the tube
bottoms out against the back of the fitting. See Fig.
18. o 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,
11/16” of the tube has entered the fitting. When a
3/8” tube is fully engaged, 3/4” of the tube has
entered the fitting. Mark tube with a piece of tape or
marker.
2. If additional tubing is required, see parts list at the
end of this manual.
To Disconnect Tubes
1. Push the collet inward with a finger tip. See Fig.20.

Step F - 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.
Complete 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 parts bag and
common household bleach (5.25%).
4. Add 3 ml. of bleach into open end of yellow tube.
Handle bleach according to bleach manufacturer’s
recommendations. See Fig. 22.
5. Connect yellow tube to tank connector. See Figs. 13
and 21.
6. Sanitizing the system will be completed during the
pressure test and purging steps on the following
page.
N TE: The bleach must be removed from the sys-
tem before drinking the water. See purging instruc-
tions on the next page.

Step F - Sanitize, Test and Purge System (cont.)
PRESSURE TEST THE SYSTEM
N TE: 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 to the Reverse
Osmosis system.
2. Purge air from the house plumbing by opening sev-
eral house faucets. Close faucets 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.
Check for water leaks. Fix leaks if any are found. If
problems exist, refer to the troubleshooting chart or
call the toll free number below).
N TE: When the system is first pressurized, water
may ''spurt'' from the faucet air gap hole until air is
expelled from the R system.
Please review the following operating features
before using your Reverse Osmosis system:
N TE: 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.
N TE: Codes in the state of Massachusetts require
installation by a licensed plumber and do not per-
mit the use of saddle valves.
If you live in the state of Massachusetts, review
plumbing code 248-CMR of the Commonwealth of
Massachusetts before proceeding with the installa-
tion.
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.
N TE: Do not consume water from the R sys-
tem until purging is complete.
2. Close 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
WORKS
Introduction: Your Reverse Osmosis (RO) rinking
Water System uses your household water pressure to
force water through three filters. Impurities are filtered
out. elicious 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 rinking 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. rain 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. Clean, 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.

1. Water enters prefilter. Sand, silt and other sediments are reduced. Chlorine is also reduced. See Fig. 24.
2. Water leaves prefilter and proceeds to the Reverse Osmosis cartridge.
3. Water enters the Reverse Osmosis membrane. issolved solids are reduced.
4. Processed water leaves the Reverse Osmosis membrane and flows to the storage tank.
5. rain 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
PREFI TER / POSTFI TER MAINTENANCE
N TE: 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). Cartridge 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 cartridge when the pro-
duction rate and/or quality of product water drops.
Product water may begin to taste different, indicating
solids and organics are passing through the Reverse
Osmosis membrane. See Reverse Osmosis cartridge
replacement.
REVERSE OSMOSIS CARTRIDGE REP ACE-
MENT
Complete the following steps to replace the cartridges.
1. Remove (turn counterclockwise) the prefilter car-
tridge from the manifold to stop flow to the Reverse
Osmosis cartridge.
2. Remove the Reverse Osmosis cartridge.
3. Remove the postfilter cartridge.
4. iscard the cartridges in a proper manner.
5. Install new cartridges in reverse order: post filter,
Reverse Osmosis and then prefilter. Turn cartridges
clockwise to reattach to the manifold. o not over-
tighten.
6. Purge the Reverse Osmosis system. See page 14
for instructions.

Maintenance
DRAIN F OW CONTRO
The flow control is required for proper operation of the
Reverse Osmosis system. See Fig. 26. The flow con-
trol, located inside the push-in elbow fitting on the
drain port of the Reverse Osmosis filter assembly,
keeps water flowing through the membrane at the
required rate. This ensures that the system produces
the best quality product water.
Periodically check the flow control to be sure the small
hole through it is clean and unrestricted.
If the flow control requires service, review the explod-
ed view in Fig. 26. Assemble and disassemble as
shown. If the flow control remains in the manifold when
the push-in elbow fitting is removed, you will need to
remove the drain port’s collet and o-ring, as shown in
the next section, to retrieve it.
CHANGE CO ET AND O-RING
1. Remove the collet and o-ring from the fitting with a
small screwdriver. o not scratch the internal walls
of the collet port. See Figs. 27 & 28.
2. Clean collet port, lubricate with silicone-based lubri-
cant, and insert the o-ring seal into the bottom of the
port. See Figs. 27 & 28.
3. Push the collet inward until it locks in place. See
