INSTALLATION REQUIREMENTS

READ THIS ENTIRE INSTALLATION AND SERVICE GUIDE BEFORE BEGINNING INSTALLATION

The 123 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 ensure a system

continues to operate at its optimum level, it is necessary to have a routine maintenance and replacement schedule (Table 3).

Frequency at which filters must be changed will depend on quality of feed water supply and level of system usage.

These RO systems contain a replaceable treatment component critical to the efficiency of the system.

Replacement of the reverse osmosis component should be with one of identical specification, as defined by WaterGroup

to assure the same efficiency. Product water shall be tested periodically to verify the system is performing properly.

Operator performs test using the optional Smartap

PREPARATION

1. Check that all appropriate components are packed

2. Determine locations for RO component installation.

with your system (Figures 1.A. and 1.B.). Refer to applicable Component Parts Breakdown (Figures 7, 9,

10.A. or 10.B.) for a complete list of parts.

COMPONENT LOCATION REQUIREMENTS Table 2

Water Quality Monitor.

Two requirements for consideration are: access to cold water supply line and household sink drainpipe. Specific requirements are detailed in Table 2.

PRODUCT WATER FAUCET

Faucet may be installed in any convenient location.

Make sure underside of location is free of obstructions.

Module may be installed under sink or in any convenient

location within 15 feet of source water supply and faucet.

REVERSE OSMOSIS MODULE*

STORAGE TANK

Tank may be placed in any space within 15 feet of faucet, generally under kitchen sink or in an adjacent unused cabinet.

Tubing length between components should be kept to a minimum, avoiding sharp bends or kinks.

DO NOT PLACE MODULE WHERE IT WILL BE EXPOSED TO FREEZING AND/OR DIRECT SUNLIGHT.

MODULE MUST BE EASILY REMOVABLE FOR PERFORMANCE OF ROUTINE MAINTENANCE.

Mount Module on side of cabinet using bracket (attached to Module) and two screws provided in the Installation Kit.

HOLD THE MODULE BY THE FILTER HOUSINGS WHEN PICKING UP OR CARRYING UNIT.

NOTE

THIS DRINKING WATER SYSTEM IS FOR USE ON POTABLE WATER SUPPLIES ONLY.

SOURCE WATER EXCEEDING CHEMICAL PARAMETERS REQUIRES PRE-TREATMENT.

COMMONWEALTH OF MASSACHUSETTS PLUMBING CODES 248 CMR SHALL BE ADHERED TO.

CONSULT WITH YOUR LICENSED PLUMBER FOR INSTALLATION OF THIS SYSTEM.

CAUTION

DO NOT USE WITH WATER THAT IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY

WITHOUT ADEQUATE DISINFECTION BEFORE OR AFTER THE SYSTEM.

MAINTENANCE REQUIREMENTS Table 3

Service Requirements Recommended Service Intervals

To insure the system operates at its optimum level, certain routine maintenance

must be performed. Frequency of maintenance performance

will depend on feed water quality and level of system usage.

CLEAN: Each time filters are replaced

SANITIZE: At least once a year and each time membrane is replaced

Replace filters as required or every 6 to 12 months

Replace membrane as required based on Smartap

Water Quality Monitor indication or periodic TDS rejection tests.

Maximum recommended service life for membrane is 60 months.

depending on feed water quality.

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 splitsecond 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.

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

INTER-COMPONENT CONNECTIONS

QUICK-CONNECT FITTINGS

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.

A. Push tube through Collet into Body. B. Tube must seat firmly at bottom of

fitting.

Figure 2: How to Use 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.).

C. Push Collet against Body to release tube.
