INSTALLATION REQUIREMENTS
READ THIS ENTIRE INSTALLATION AND SERVICE GUIDE BEFORE BEGINNING INSTALLATION
Hydrotech®101 and 103 Series Reverse Osmosis (RO) Drinking Water Treatment Systems have been designed for ease
of installation and serviceability. They are constructed with the finest materials available.
Using these instructions and paying close attention to parameters outlined within
"CONDITIONS FOR USE" detailed on Page I will ensure a successful installation.
All systems must be installed in accordance with applicable city, state, and local plumbing codes. To insure a system
continues to operate at its optimum level, it is necessary to have a routine maintenance and replacement schedule (Page
16). The frequency at which filters must be changed will depend on quality of feed water supply and level of system usage.
Hydrotech®RO systems contain a replaceable treatment component critical to effective reduction of
Total Dissolved Solids (TDS). Product water shall be tested periodically to verify the system is performing properly.
Operator performs test using the Smartap®Water Quality Monitor.
PREPARATION
1. Check that all appropriate components are packed
with your system (Figure 1). Refer to applicable
Component Parts Breakdown (Figures 9, 11, 12, 13,
or 14) for a complete list of parts.
2. Determine locations for RO component installation.
Two requirements for consideration are: access to
cold water supply line and household sink drain pipe.
Specific requirements are detailed in Table 1.

SMARTAP®WATER QUALITY MONITOR
Hydrotech®101, 102, and 103 Series Reverse Osmosis Systems incorporate a proven performance indicator. Our patented
Smartap®Water Quality Monitor uses dual probe LOGIC PULSE MEMORY technology to accurately indicate membrane
performance. A split-second power pulse compares feed water Total Dissolved Solids (TDS) level with that of the product water.
Then, by reversing the polarity of the electronic pulse, the probes are cleaned and kept free of chemical plating. A nine-volt
alkaline battery provides power to the Monitor. To prolong battery life, indicator lights self-extinguish after a few seconds even if
the button is being pressed or water is being dispensed. For optimum monitor performance, the battery should be replaced each
time system is sanitized.
NOTE: Monitor Troubleshooting Indicators and Common Solutions are shown in Table 2 on Page 19.
THE SMARTAP® WATER QUALITY MONITOR IS AVAILABLE IN TWO MODELS
Pushbutton Actuated Smartap®
Pressing a test button located on the manifold cover activates monitor. When button is pressed, and momentarily held down,
monitor reports membrane status by illuminating a light located next to test button. A green light means system is operating
normally. A yellow light indicates system needs servicing (membrane may be depleted or fouled). While the button may be
pressed at any time, the most accurate readings are obtained when the system is making water.
Faucet Actuated Smartap®
Monitor is activated by opening product water faucet or extra point-of-use device. When monitor is activated, it reports system
status by illuminating a light appearing in a light bar located at faucet base (Chrome or Stainless Steel faucet) or integrated
into faucet body front cover (Polymer faucet). A green light means system is operating normally. A yellow light means
membrane may be depleted or fouled. An orange light means a trained technician should service the system.
INTER-COMPONENT CONNECTIONS
Connections between cold water supply line, RO Module, storage tank, product water faucet, and drain line are accomplished
using plastic tubing and push-together quick-connect type fittings.
PLASTIC TUBING
1. Cut tube ends square and straight. Do not deform
tube (i.e., cause tube to compress its diameter so it
is no longer round).
2. Make sure outer surface of tube is clear of marks or
scratches for a length equal to twice tube diameter.
This allows "O" ring to seat properly against tube.
3. Avoid sharp changes in direction when routing
tubing. Sharp turns cause tubing to flex and deform,
which reduces its flow capacity and may increase
lateral stress on the fittings, causing leakage.
QUICK-CONNECT FITTINGS
Fittings consist of two parts: a Body and a colored Collet.
Collet color corresponds to tubing color to be used at
that connection (Figure 2.A.).
1. To install a tube, push it through Collet until it seats
firmly at bottom of fitting (Figure 2.A and 2.B.).
2. To remove a tube, push and hold Collet against
Body while pulling tube out (Figure 2.C.).
NOTE: Systems are shipped with a plug in each fitting
(prevents leakage of sanitizing fluid). Remove a
plug in same manner as a tube.
A. Push tube through Collet into Body B. Tube must seat firmly at bottom of fitting C. Push Collet against Body to release tube

PRODUCT WATER FAUCET SITE PREPARATION
Refer to Faucet Installation Instructions (Pages 8 & 10) for site location and mounting hole specifications.
Primary considerations for site selection are convenience of use and an open area under sink.
Always check underside of selected location for obstructions.
PORCELAIN/ENAMEL OVER STEEL
OR CAST IRON SINKS
NOTE: A heavy duty, variable speed drill motor is
recommended for this procedure.
Use of a spring-loaded porcelain drill set is
strongly recommended (Figure 7).
- 7 -
The plastic sleeve supplied on pilot drill (Figure
7.A) is to be positioned on drill bit against drill
chuck. This prevents chuck from contacting
porcelain after pilot hole has been completed.
Suggestion: Practice on discarded sinks to familiarize
yourself with operation of porcelain cutter kit.
CAUTION: Avoid high motor R.P.M. during initial
penetration of porcelain, as high drill speed
will cause excessive chipping.
1. Using carbide tipped bit with plastic sleeve (Figure
7.A.), drill pilot hole completely through porcelain and
metal underneath.
2. Place spring-loaded porcelain saw (Figure 7.B.) into
drill chuck. Make sure pilot guide is inserted tightly.
Insert pilot guide into pilot hole. Push down gently on
drill motor to apply light pressure to porcelain surface.
Start drill motor turning as slowly as possible.
After initial cut has started, motor speed may be
gradually increased. The cut may require three to
four minutes to complete. Going faster could result in
excessive chipping. Be sure a complete ring has
been cut through porcelain to material underneath.
3. Place finish hole saw (Figure 7.C.) into drill chuck.
Make sure pilot guide is inserted tightly. Insert pilot
guide into pilot hole. Begin cut using a slow speed
and light pressure until porcelain (inside ring cut in
Step 2) has been penetrated to material underneath.
4. Remove saw from hole and clean all debris from
porcelain surface. Re-insert saw into hole and cut
through remaining material.
TILE COUNTER TOP
1. Follow procedures detailed in section labeled
"Porcelain/Enamel Over Steel" (substitute "tile" for
"Porcelain" in instructions).
STAINLESS STEEL SINK
1. Use a center punch to make a small indentation to
mark center of desired location.
2. Drill a pilot hole with a 1/8" metal drill bit, then enlarge
hole with a 3/8" metal drill bit.
3. Complete hole size by using a 1 1/4" chassis punch
available from your dealer (P/N 36201006).

ACTIVATING THE SYSTEM
NOTE: Make sure all water supply lines, drain lines, and fittings are secure and free from leakage.
1. Open source water supply valve. Close product
water faucet. Check for leakage.
2. Turn tank valve one-quarter turn counter- clockwise to
open valve (handle should be in line with tubing as it
enters connection).
3. Confirm system is producing water. Module will be
sending rinse water to drain.
NOTE: Battery is located inside manifold cover.
Use caution when working with manifold cover.
Wiring therein connects monitor components. If
wires, circuit board, or connections are damaged
and/or wetted, monitor will not function.
Connect battery to monitor after system has been
in production mode for at least 5 minutes. This
ensures sensing switch is in proper position to
record data.
Item Callouts refer to Page 12, Figure 12 (101
Series) or Page 13, Figure 13 (103 Series) unless
noted otherwise.
4. Loosen mounting bracket screws (Item 7). Gently pull
module cover (Item 1) up and away from the manifold
body.
5. Connect battery (Item 2) by pressing clip onto battery
terminals (Page 18, Figure 15).
6. Replace module cover and tighten screws.
7. Test battery connection by activating monitor. Open
product water faucet or press pushbutton, whichever
is applicable. If an indicator light illuminates,
connection is good.
NOTE: Close faucet immediately after light illuminates.
Test is to confirm battery connection, not water
quality.
8. Open product water faucet and let water flow until all
air has been expelled from system. Lock faucet
open by rotating handle 90º or by lifting handle,
whichever is applicable.
9. Close product water faucet. In 30 minutes, check
connections for leaks and correct if necessary.
Icemaker/Extra point of use: Check connections on
these supply lines for leaks.
10 Allow storage tank to fill overnight.
DO NOT USE
THE FIRST FULL STORAGE TANK OF WATER
11 Discard (to drain) first full tank of water by opening
product water (and extra point-of-use) faucet until
water flow stops, then close faucet. This will flush
sanitizing solution from system.
Icemaker: Let tray/bin fill with ice cubes. Discard all
ice cubes. This flushes sanitizing solution from lines
to icemaker.
NOTE: System is ready to use. Should there be any
aftertaste or odor to water or ice cubes, repeat
Steps 10 and 11.
DO NOT USE THE FIRST STORAGE TANK OF WATER
Allow storage tank to fill overnight. Dispense this water to drain.
This process removes factory-installed sanitizing solution from the entire system and sends it to drain.
This process also sanitizes fittings and tubing used during installation.
