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
