CMR shall be adhered to. Please consult your licensed
plumber. Using a qualified installer is recommended.
The Drinking Water System works on water pressures of 40
psi minimum, to 100 psi maximum (see the table on Page 4). If
house water pressure is over the maximum, install a pressure
reducing valve in the water supply line to the Drinking Water
System.
This system is acceptable for treatment of influent concen-
trations of no more than 27 mg/L nitrate and 3 mg/L nitrite
measured as N and is certified for nitrate/nitrite reduction
only for water supplies with a pressure of 280 kPa (40 psig) or
greater. This system is supplied with a nitrate/nitrite test kit.
Product water should be monitored periodically according to
the instructions provided with the test kit.
DO NOT install the Drinking Water System outside, or in
extreme hot or cold temperatures. Temperature of the water
supply to the Drinking Water System must be between 40°F
(minimum) and 100°F (maximum), see the table on Page 4. DO
NOT INSTALL ON HOT WATER.

be sure the water supply conforms.
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or
after the system. Systems certified for cyst reduction may be
used on disinfected water that may contain filterable cysts.
This system shall only be used for arsenic reduction on
chlorinated water supplies containing detectable residual free
chlorine at the system inlet. Water systems using an inline
chlorinator should provide a one minute chlorine contact time
before the RO system. Conforms to NSF/ANSI 58 for pentava-
lent arsenic reduction. See performance data sheet and

WHAT THE DRINKING WATER SYSTEM WILL DO
COMPONENTS OF THE SYSTEM
The drinking water system is a REVERSE OSMOSIS (RO)
water treating unit. Reverse osmosis is a way of reducing
dissolved solids and organic matter from water by pass-
ing it through a special membrane. The membrane sepa-
rates minerals and impurities from the water, and they are
flushed to the drain. Good tasting, high quality product
water goes directly to the drinking water faucet, or to the
storage area. The system makes a good supply of drink-
ing water each day (see specifications). How much it will
make depends on the feed water supply pressure, temper-
ature, and quality.
Pre and postfilters are replaceable cartridges. The carbon
prefilter reduces some chlorine (see specifications) while
also filtering sediments. The postfilter reduces any other
undesirable tastes and odors before you use the water.
The RO system also includes a standard faucet assembly
to vend the drinking water, and a storage tank.
NOTE: A performance data sheet is included listing what
the system will reduce from the water supply. See per-
formance data sheet for individual contaminants and
reduction performance.
The drinking water system fits under the kitchen or bath-
room sink. However, you can install it where most con-
venient. You do need a COLD water supply pipe and
drain point within a few feet (6' tubing lengths included).
You can buy longer lengths of tubing if needed to reach
more distant points. Be sure tubing is acceptable for use
on potable water supplies.
The RO system is shipped in one carton, consisting of:
(1) Storage Tank,
(2) Faucet,
(3) RO Assembly, with color coded tubing lengths
attached,
(4) Parts bag containing storage tank shutoff valve, drain
flow restrictor, mounting washers and screws.
(5) Separate 30" length of 3/8" tubing.
(6) Hydrolink™ RO Module, with batteries and cable, in
its own box (Model HERO-375 only).
INSTALLER PROVIDES: (1) fittings to tap the cold water
pipe for a feed water source to the RO . . . must adapt to
1/4" tubing; and (2) a drain point for RO discharge water .
. . must adapt to 3/8" OD tubing. Both items must comply
with state and /or local codes. Optional fittings are avail-
able from EcoWater for use in areas where codes permit.
THINGS TO CHECK BEFORE YOU START TO
INSTALL:
FEED WATER - The water supply to the Drinking
Water System must have the qualities listed in the specifi-
cations. If not, it will not make product water as it should
and life of the RO membrane is shortened. City water
most often will have these qualities. Well water may need
conditioning. Have the water tested by a water analysis
laboratory, and get their recommendations for treatment.
Observe plumbing codes when providing a water supply
to the RO. A self-piercing saddle valve is available for tap-
ping into a cold water pipe (check local plumbing codes).
Refer to Pages 24 and 27.
NOTE: Codes in the state of Massachusetts require instal-
lation by a licensed plumber, and do not permit the use of
the drain clamp. For installation, use plumbing code 248-
CMR of the Commonwealth of Massachusetts.
CAUTIONS:
Feed water must have chlorine reduced (prefilters reduce
up to amount shown in specifications, Page 4). Chlorine
will destroy the RO membrane cartridge. Be sure to serv-
ice the prefilters, Page 19.
DRAIN POINT - A suitable drain point (check your
local plumbing codes) is needed for reject water from the
RO membrane cartridge. Running the RO drain tubing
directly to a floor drain, laundry tub, sump, standpipe,
etc., is preferred. If that is not possible or practical, using
the sink p-trap drain pipe is suggested. A drain clamp
(drilling required), or a special drain adapter are available
from EcoWater to use where codes permit. Refer to Pages
24 and 27. These options install on the sink drain pipe
tailpiece, above the p-trap.
RO FAUCET - The RO product water faucet installs on
the sink, or on the countertop next to the sink. Often, it's
installed in an existing sink spray attachment hole. Space
is required underneath for tubing to and from the faucet,
and for securing it in place. Refer to Pages 7 and 10.
MOUNTING SURFACE - The RO assembly mounts
on a wall surface under the sink, or you can lay it on the
bottom of the cabinet. Special washers and screws are
included for wall mounting.When the storage tank is full
of water, it weighs about 30 pounds. Be sure to set on a
surface that will support this weight.

INSTALLATION - FEED WATER SUPPLY
REJECT WATER DRAIN FITTING
Check and comply with local plumbing codes as you
plan, then install a cold feed (supply) water fitting. The
fitting must provide a leak tight connection to the RO
1/4" OD tubing, see Figure 6, Page 10. A typical installa-
tion, using standard plumbing fittings is shown in
Figure 1. A saddle valve (part no. 7011272) is available
to use where codes permit. Installation instructions are
on Page 24.
NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber, and do not permit
the use of the drain clamp. For installation, use plumb-
ing code 248-CMR of the Commonwealth of
Massachusetts.
PIPE FITTINGS (compression shown)
IMPORTANT: Before starting, close the hot and cold
water shutoff valves (See Figure 1). Use a pan to catch
water when disassembling the pipe.
Complying with plumbing codes, install a fitting on the
kitchen cold water pipe to adapt 1/4" OD tubing. A typ-
ical connection is shown in Figure 1. You can use solder
or threaded fittings. If threaded fittings are used, be
sure to use pipe joint compound or Teflon tape on out-
side threads.
Do not connect the tubing to the fitting until Step 2, top
of Page 10.
Running the RO drain tubing directly to a floor drain,
laundry tub, sump, standpipe, etc., is preferred. If that
is not possible or practical, check and comply with
local plumbing codes as you plan, then install a drain
fitting for RO reject water. This fitting is usually
installed at the sink p-trap (always above). It must pro-
vide a leak-tight connection to 3/8" OD tubing from the
RO product water faucet airgap, see Figure 6, Page 10.
Typical drain fitting installations are listed below. A
drain adapter (part no. 7192230) is available to use
where codes permit. Installation instructions are on
Page 24. Other options are shown on Page 27.
“Y” BRANCH TAIL PIECE, OR OTHER APPROVED
P-TRAP DRAIN
Reject water from the RO is routed to the RO faucet air-
gap (1/4" tubing), then to the drain point with 3/8" OD
tubing. COMPLYING WITH PLUMBING CODES,
install a fitting to accept the 3/8" tubing. Figure 2 shows
typical p-trap and "Y" branch tail piece type drains.
Do not connect drain tubing until Step 1, top of Page 10.
FIGURE 1
FIGURE 2
INSTALL THE FAUCET
Select one of the following places to install the faucet.
Be sure there's room underneath so you can make the
needed connections.
In an existing sink spray attachment hole.
Drill a hole in the sink top.
Drill a hole in the countertop, next to the sink.
NOTE: Looking at Figure 3, be sure the faucet base will
fit flat against the surface at the selected location so the
o-ring will seal.
1. Do not connect drain tubing until Step 1, top of
Page 10.
2. For Model ERO-375, slide the chrome washer onto
the faucet stud, Figure 3.
3. For Model HERO-375, snap the o-ring in the
groove on the bottom of the ring and slide the monitor
ring onto the faucet stud. The monitor ring LED wire
must be routed through the sink or countertop hole
and through the spacer, if used, Figure 3.
NOTE: If you will route the RO drain tubing directly to
the drain point, disregard Steps 4 and 6 and do Step 1
on top of Page 10.
4. Take the 30" length of 3/8" black tubing and push
one end onto the 3/8" faucet barb fitting, Figure 4.
5. Move the RO system into position, under the sink.
(Referring to Page 8, hang the system on cabinet wall,
or lay on the floor surface, as desired.)
6. Route the 1/4" red tubing from the bottom, up
through the faucet mounting hole. Push the end of the
tubing onto the 1/4" barb fitting.
7. Work tubing and the faucet stud down, into the
mounting hole.
8. On the underside of the sink or countertop, install
the spacer (Model HERO-375 only), plastic bushing, flat
washer, and hex nut. Slide the large steel washer in
place, between the bushing (or spacer) and the bottom
of the sink or countertop. Then, tighten the hex nut
securely. Make sure that the LED wire is in a position
so that it will not be cut, pinched or kinked before
tightening the faucet assembly.
9. Thread the tubing connector onto the bottom of the
faucet stud.
10. Push the end of the 3/8" blue tubing from the RO,
into the tubing connector installed in Step 9.
NOTE: See tubing connection procedures on Page 9.
For ease of service and maintenance, keep tubing
lengths long enough so removal of the RO system from
under the sink is possible.

TUBING CONNECTIONS
HOW TO CUT AND CONNECT THE TUBES
Your Reverse Osmosis Water System includes push-in
fittings for quick tubing connection. Review the follow-
ing instructions before connecting the tubes in the next
step.
Cut tubes to length
1. Use a sharp cutter or knife to cut the end of tubing.
Always cut the tubing square.
2. Inspect the end (about 1") of the tubing to be sure
there are no nicks, scratches or other rough spots. If
needed, cut the tubing again.
NOTE: Tubing lengths should allow for the removal of
the assembly from the hanger washers 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. Continue pushing until the tube bottoms out
against the back of the fitting. A common mistake is to
stop pushing when the tube engages the o-ring. This
will 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.
2. If using tubing other than tubing supplied with the
system, be sure it is of high quality, exact size and
roundness with a smooth surface.
Disconnect Tubes
1. Push the collet inward with a finger tip.
2. Continue holding collet inward while pulling the
tubing out.
Cut tubing square with end of tubing round,
smooth, with no cuts, nicks or flat spots.

CONNECT WATER SUPPLY, STORAGE TANK AND DRAIN TUBING
1. Connect faucet drain tubing (if using p-trap
drain): Run the 3/8" black tubing from the 3/8" faucet
barb, to the drain fitting installed on page 6. Keep this
tubing run as straight as possible, without loops, dips
or low-spots. Cut the tubing as needed and fasten to
the drain fitting, securing as required (pages 6 and 24).
Or, connect RO drain tubing (if using floor drain or
other approved drain point): Route the 1/4" red tubing
from the RO to the floor drain, sump, etc. Be sure to
provide an air gap when securing in place.
2. Install Flow Control Insert: Before connecting the
1/4” red tubing to the RO system manifold’s drain port,
take the flow control insert from the parts bag and
insert it into the end of the tube, as shown below.
3. Connect water supply tubing: A length of 1/4 "
green tubing is attached to the RO inlet. Connect this
tubing to the feed water supply fitting, installed on
page 6. Connect the tubing as applies (Figures 1 and 6)
and tighten the nut securely.
