- Page 5 INTRODUCTION The separation of dissolved solids and water using RO membranes is a pressure driven temperature dependent process. The membrane material is designed to be as permeable to water as possible while maintaining the ability to reject dissolved solids. The main system design parameters require the following: Internal flows across the membrane surface must be high enough to prevent settling of fine suspended solids on the membrane surface.

- Page 7 B. RO OVERVIEW Reverse osmosis systems utilize semipermeable membrane elements to separate the feed water into two streams. The pressurized feed water is separated into purified (product) water and concentrate (reject) water. The impurities contained in the feed water are carried to drain by the reject water.
- Page 8 recommended. Iron & Manganese - These foulants should be removed to less than 0.1 ppm. Special media filters and/or chemical treatment is commonly used. pH - The pH is often lowered to reduce the scaling potential. Silica: Reported on the analysis as SiO2. Silica forms a coating on membrane surfaces when the concentration exceeds its solubility.

- Page 12 III. OPERATION A. INSTALLATION The water supply should be sufficient to provide a minimum of 20 psig pressure at the design feed flow. Proper pretreatment must be determined and installed prior to the RO system. A fused high voltage disconnect switch located within 10 feet of the unit is recommended.
- Page 13 Do not apply power to the RO unit at this time. D. STARTUP 1. Verify that the pretreatment equipment is installed and working properly. Verify that no free chlorine is present in the feed water. 2. Verify that the on/off switch is in the off position. 3.
- Page 14 E. Controllers Two controller options are available. Controller option # 1 is a basic controller with an on / off switch, low pressure, tank level, and pretreatment interlock (see figure # 2). Automatic low pressure reset If the unit shuts down due to low pressure, a red light on the front of the controller will illuminate.
- Page 15 Controller option # 2 is the CI 1000. This is a microprocessor based controller with a product water conductivity meter. A separate manual for this controller begins on the next page. The autoflush option is available with both controllers. On controllers # 1, the flush valve is preset to open for 2 minutes every time the pump starts and 2 minutes every hour.

- Page 18 INTRODUCTION The 3501 Reverse Osmosis Controller is designed to control and monitor the operating parameters of a reverse osmosis water purification system. Information is displayed on a back-lit liquid crystal display, and on individual light-emitting diodes (LEDs). Functions and controls are operated through snap-dome switches (see Figure 1). Features Temperature Compensated Conductivity Monitor Water Temperature Monitor...
- Page 19 Outputs Inlet Solenoid: A 24 VAC output is provided to power the inlet solenoid. This output always energizes 12 seconds before the pump turns on, and de-energizes 12 seconds after the pump turns off. Flush Valve: A 24 VAC output is provided to power the optional reject solenoid valve.
- Page 20 Pretreatment Interlock: This is a dry contact that signals the system to shut down when a pretreatment device is not functioning, or regenerating. This could be used on a water softener, multi media filter, chemical feed pump, differential pressure switch, etc. This contact is normally open. When a circuit is not complete between the two terminals the system will operate.
- Page 21 Select Button: This button is used to select a function or parameter so that it can be reviewed or changed. Up Arrow. This button increases the value of, or advances to the next option of, the function selected. Down Arrow. This button decreases the value of, or advances to the next option of, the function selected.
- Page 22 OPERATION The key switch must be in the ON position (see Figure 1). Contrast Adjustment Press the up or down arrow when the Alamo Water logo is displayed to increase or decrease the contrast of the display. Operation Screen When the Start/Stop button is pressed the inlet valve will open. After a 12 second delay the pump will start.
- Page 23 AUTOFLUSH: (0-10 minutes) This is the length of the flush cycle. The system will flush for this amount of time every hour in tank feed and standby modes. Timer Screen Pressing either the ACCEPT or the RESET button from the configuration screen brings up the timer screen.
- Page 24 III. SERVICE AND MAINTENANCE The 3501 Reverse Osmosis Controller is designed for ease of maintenance and minimum service. Since the highest quality of electronic semiconductor components are used in this design, it is not likely that circuit malfunctions or failures will occur. It is our recommendation that service be limited to identifying malfunctions at the board level and that component level troubleshooting be referred to the factory.
