SMARTAP ® WATER QUALITY MONITOR
WaterGroup’s 12303 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. 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 4 on Page 15.
Push Button Actuated Smartap

- 12303 Series
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.
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.).
A. Push tube through Collet into Body. B. Tube must seat firmly at bottom of
fitting. C. Push Collet against Body to release
tube.
