INTRODUCTION Your R2-Series Reverse Osmosis S System is a durable piece of equipment which, with proper care, c will last for many years. This User’s Manual outlines installation, operation,, maintenance, and troubleshooting details vital to the sustained performance of your system. The test results which are included with this Use User’s r’s Manual indicate your system’s permeate (product) and concentrate (waste) test results.
FEED WATER AND OPERATION SPECIFICATIONS Nothing has a greater effect on a reverse osmosis system than the feed water quality NOTE: IT IS VERY IMPORTANT TO MEET THE MINIMUM FEED WATER REQUIREMENTS. FAILURE TO DO SO WILL CAUSE THE MEMBRANES TO FOUL AND VOID THE MANUFACTURER’S WARRANTY. NOTE: HIGHER TDS AND/OR LOWER FEED WATER TEMPERATURES WILL REDUCE THE SYSTEM’S PRODUCTION.
The amount of permeate water recovered for use use is expressed as a percentage. To calculate % recovery and % rejection, use the following formula formulas: % Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100 Example: 25% = (1.04/4.04) x 100 % Rejection = (Feed TDS – Product TDS)/(Feed TDS) x 100 Example: 99.2% = [(10,000-80)/10,000] x 100 NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS UNITS.
Locate the 1” or 3/4” connection (D (Depending on the unit) labeled concentrate and attach to a drain. Run the concentrate line to an open drain in a free and unrestricted manner (no backpressure). It is advised that an air-break break be used on the concentrate line to prevent siphoning of water from the pressure vessels when the system is in standby. CAUTION: ANY RESTRICTIONS OR BLOCKAGE IN THE DRAIN LINE CAN CAUSE BACKPRESSURE, WHICH WILL INCREASE THE SYSTEM’S OPERATING PRESSURE.
If any damage occurs to your system’s pump, a re-build kit is available. Contact your local dealer or distributor and inform them of your system’s model and pump size. MOUNTING The free standing system should be bolted down in compliance with local regulation standards or securely fastened. MEMBRANE ELEMENTS R2-Series reverse osmosis systems come pre-loaded with FILMTEC® LC LE membranes, unless otherwise specified. General membrane element performance characteristics are listed on the following pages.

SYSTEM PURGING Carefully inspect your system before initial start-up. Check that all plumbing and electrical connections are not loose or have not come undone during shipment. A User’s Manual, Test Results, and Filter Housing Wrench will accompany your R2-Series Reverse Osmosis System. NOTE: LEAVE THE POWER TO THE SYSTEM OFF FOR THIS PROCEDURE. 1. Redirect permeate water to the drain for this procedure. 2. Fully open the concentrate valve (Counter Clockwise). (Figure 1B, Page. 15) 3.
DESIGN BASIS FOR R2-1140, R2-2140, R2-3140, R2-4140, R2-5140, R2-6140 Specifications WARNING: NEVER EXCEED THE SYSTEM’S MAXIMUM PRESSURE RATING.
OPERATING DOs AND DON’Ts DO: Change the cartridge filters regularly Monitor the system and keep a daily log Adjust the system recovery to the recommended value Always feed the pump with filtered water DON’T: Permit chlorine to be present in the feed water Shut down the system for extended periods without preservation Close the control valves completely Operate the system with insufficient feed flow Operate the pump dry OPERATION AND MAINTENANCE The reverse osmosis process
PERMEATE (PRODUCT) FLOW METER AND CONCENTRATE (WASTE) FLOW METER The permeate and concentrate flow meters indicate the flow rates of the permeate and concentrate water. The measurements, when added together, also indicate the feed water flow rate or total flow rate. LOW PRESSURE SWITCH The low pressure switch shuts off the system when the feed water pressure drops below 5 PSI, preventing damage to the pump. The system restarts automatically when there is a constant pressure of 35 PSI or more.
MEMBRANE REMOVAL AND REPLACEMENT Replacing membranes in the pressure vessels is an easy process if you have the proper information and tools at hand. Please refer to the following instructions when removing and replacing membrane elements: WARNING: ALL PRESSURE GAUGES MUST READ ZERO BEFORE PROCEEDING. BEFORE ATTEMPTING, DISCONNECT THE POWER FROM THE SYSTEM AND BLEED ALL WATER PRESSURE FROM THE SYSTEM. 1. Remove the end plugs from the top of the pressure vessels.
REPLACING THE MEMBRANE ELEMENT: WARNING: THE BRINE SEAL MUST BE IN THE SAME POSITION FOR EACH MEMBRANE ELEMENT HOUSING, SO MARK EACH HOUSING PRIOR TO REMOVING THE MEMBRANE ELEMENTS. THE BRINE SEAL IS A RUBBER SEAL THAT PROTRUDES ON ONE SIDE OF THE MEMBRANE AND IS ALWAYS ON THE FEED SIDE OF THE MEMBRANE ELEMENT. 1. Remove one membrane element at a time from the pressure vessels, from the top of each housing.

FLUSHING THE SYSTEM The system should be flushed weekly to remove sediment from the surface of the membranes. To manually flush the system, follow the preceding steps: 1. The system must be operating during the flush procedure. 2. Fully open the concentrate valve. (Figure 1B, Page. 15) 3. Allow the system to run for 10 to 20 minutes. 4. After 10 to 20 minutes, close the concentrate valve to its previous setting. Ensure the proper concentrate flow rate is going to the drain. 5.
7. Fully open the concentrate valve. 8. Drain the flow meters. 9. Allow the system to drain for a minimum of eight hours or until the opened ports quit dripping. 10. After draining is complete, reconnect all of the plumbing.
REVERSE OSMOSIS TROUBLESHOOTING SYMPTOMS LOW INLET PRESSURE POSSIBLE CAUSES CORRECTIVE ACTION Low inlet pressure Increase inlet pressure Cartridge filters plugged Change filters Solenoid valve malfunction Concentrate valve might be damaged Leaks Replace sol.
ABNORMAL PERMEATE FLOW As time progresses, the efficiency of the membrane will be reduced. In general, the salt rejection does not change significantly until two or three years after installation when operated on properly pretreated feed water. The permeate flow rate will begin to decline slightly after one year of operation, but can be extended with diligent flushing and cleaning of the system. A high pH and/or precipitation of hardness can cause premature loss in rejection.
TEMPERATURE CORRECTION FACTORS FOR MEMBRANE Find the temperature correction factor (TCF) from the table below. Divide the rated permeate flow at 77°F by the temperature correction factor. The result is the permeate flow at the desired temperature. (See example on the next page). If a system is rated to produce 5 gpm of permeate water @ 77˚ F. The same system will produce more water at a higher temperature. It will also produce less water at a lower temperature.
5 gpm @ 59˚ F (5÷1.42=3.52 gpm) 5 gpm @ 77˚ F (5÷1=5 gpm) 5 gpm @ 84˚ F (5÷0.89=5.62 gpm) SERVICE ASSISTANCE If service assistance is required, please complete the following process: Contact your local dealer or distributor. Prior to making the call, have the following information available: system installation date, serial number, daily log sheets, current operating parameters (e.g. flow, operating pressures, pH, etc.), and a detailed description of the problem.
