  • Page 7: Introduction

    INTRODUCTION MANOWNROLH 1. 0 INTRODUCTION Congratulations on your selection of this U.S. Filter water purification system. This system is designed and manufactured to the highest standard of quality and fully tested and inspected by competent personnel. In order to get maximum performance, we ask you to read all of the following instructions before installing and operating this system.

  • Page 8: Functions Of The System Components

    INTRODUCTION MANOWNROLH Quality audits do not improve products. They do, however, insure that a system meets or exceeds specifications required for your system. In the Appendix is a copy of our Quality Control form for your system. FUNCTIONS OF THE SYSTEM COMPONENTS Reverse Osmosis Membranes The prefiltered water enters the RO housing and passes over the surface of an RO membrane.
  • Page 9 INTRODUCTION MANOWNROLH mode. To prevent membrane degradation, the system will continue to flush during the "TANK FEED" mode and during "STANDBY" conditions. Controller (optional) The controller has the following capabilities: Low pressure shutdown - when the inlet water pressure falls below 1.38 bar (20 psi).

  • Page 10: System Installation

    SYSTEM INSTALLATION MANOWNROLH 2. 0 SYSTEM INSTALLATION PRECAUTIONS BEFORE INSTALLATION The following are input water source requirements: Inlet pressure is .69 to 6.9 bar (10 to 100 psig) at design feed flow. Temperature is between 2°C (35°F) and 45°C (113°F). Recommended operating temperature is 25°C (77°F).

  • Page 11: Water Requirements

    SYSTEM INSTALLATION MANOWNROLH Branch circuit conductors supplying the motor shall have an ampacity of not less than 125% of the motor full load current rating as defined by the National Electric Code. WATER REQUIREMENTS The inlet water supply must be adequate to provide the minimum flow requirement shown in the System Specifications in the Appendix.

  • Page 12: Before Power Turn On

    SYSTEM INSTALLATION MANOWNROLH BEFORE POWER TURN ON The controller circuit board should be installed in the controller housing before connecting electrical power to the unit. Personal injury and permanent damage to the controller can result if the WARNING controller is installed with power on the unit. Once the inlet water is plumbed to the system and the electrical power is connected, the electrician should verify correct motor rotation.

  • Page 13: Operating Instructions

    OPERATING INSTRUCTIONS MANOWNROLH 3. 0 OPERATING INSTRUCTIONS CONTROLS AND INDICATORS The controls and indicators used in the operation of the system are outlined in the Appendix. The operator must be thoroughly familiar with the controls and their respective functions for proper operation and in order to maintain the quality of the permeate and eliminate unnecessary shutdowns.

  • Page 14: Initial Flushing Of The System

    OPERATING INSTRUCTIONS MANOWNROLH INITIAL FLUSHING OF THE SYSTEM Since the RO membrane is shipped moist with sodium bisulfite preservative solution, initial flushing of the system is required. Before operating a new system, and also after a replacement of an RO membrane, perform the following steps: Place the outlet of the permeate at a convenient drain.

  • Page 15: Prolonged Shutdown (Greater Than 4 Days)

    OPERATING INSTRUCTIONS MANOWNROLH PROLONGED SHUTDOWN (GREATER THAN 4 DAYS) When the system is going to be inactive for more than 4 days (not in a "STAND-BY" mode), perform the following steps: Turn off the input water source. Bisulfite Sanitization (4 days to 1 month shutdown) Drain water from the system and pump in a 0.5% sodium bisulfite solution to prevent biological growth in the elements.

  • Page 16: System Maintenance

    SYSTEM MAINTENANCE MANOWNROLH 4. 0 SYSTEM MAINTENANCE GENERAL Routine customer maintenance procedures consists of periodic replacement of the RO membranes and the filter cartridges in the prefilter unit and sanitization of the RO membranes and the storage reservoir. Cleaning/sanitizing is recommended every four to eight weeks.
  • Page 17 SYSTEM MAINTENANCE MANOWNROLH Hydrogen Peroxide Advantages of using hydrogen peroxide are that it has no toxic vapors, is biodegradable, is easily disposable, has good biocidal activity, and breaks down into oxygen and water, which does not harm the environment. Because of these qualities, operators can be assured that they are not handling toxic materials.
  • Page 18 SYSTEM MAINTENANCE MANOWNROLH on line. Use the following guidelines to determine if the system is clear of residual sanitizing agents. Formaldehyde The product water should be analyzed with the Fast Formalert or other formaldehyde test kit until detection limits are reached. Hydrogen Peroxide The product water should be analyzed with a hydrogen peroxide test kit.
  • Page 19 SYSTEM MAINTENANCE MANOWNROLH Recirculation Method This method requires an accessory tank and booster pump. A sanitant solution is prepared in the tank and fed to the RO system via the booster pump. The product and reject streams are diverted to the tank and the sanitant is recirculated through the system for a period of time.
  • Page 20 SYSTEM MAINTENANCE MANOWNROLH system. Localized areas of high sanitant concentration could degrade the RO membranes. Also, the length of time that the RO pump is turned on will be different with each model of RO system and the means used to introduce the sanitant.
  • Page 21 SYSTEM MAINTENANCE MANOWNROLH Factors to Consider when Cleaning RO Cartridge Use RO product water for cleaning and rinse solutions. Use RO product water to prepare cleaning solutions, and as flush water between each cleaning step. If RO product water is not available, use softened filtered tap water.
  • Page 22 SYSTEM MAINTENANCE MANOWNROLH Flush the cleaning chemical from the system, starting with a 10 to 15 minute manual flush cycle. Then place the system in the operate mode, and for the first ten minutes, reduce the feed pressure to approximately half of the normal operating pressure by opening the reject throttle valve.

  • Page 25: Sanitizing A Storage Reservoir

    SYSTEM MAINTENANCE MANOWNROLH New thin film composite cartridge MUST be operated for a minimum of 24 CAUTION hours before contact with formalin, or a permanent reduction in flow rate may occur. SANITIZING A STORAGE RESERVOIR A storage reservoir can easily become contaminated with bacteria, and if this is critical to the end use of the water, it should be regularly monitored using a sampling device.
  • Page 26 SYSTEM MAINTENANCE MANOWNROLH Conductivity Observe input and permeate conductivity daily; and record weekly. Record percent salt rejection weekly. Flow Rates Check daily and record permeate and reject flow rate weekly. Calculate the percent recovery using the following formula: Permeate Flow Rate = % Recovery Permeate Flow Rate and Reject Flow Rate The percent recovery should not exceed the design value shown on the...

  • Page 27: Troubleshooting

    TROUBLESHOOTING MANOWNROLH 5. 0 TROUBLESHOOTING SYSTEM INOPERATIVE Check to see if power is available to the unit and turned on. Check to see that the motor starter relay is engaging, and if the control lights come on but the pump does not start. With an ohm meter, check to see if the motor starter coil is burned out.

  • Page 28: Low Salt Rejection

    TROUBLESHOOTING MANOWNROLH LOW SALT REJECTION Check flows per the System Specifications sheet in the Appendix, and adjust if necessary. Another possibility is high CO content in the inlet water. CO readily permeates the membrane. High CO content water will also have a pH of less than 6.0. Low temperatures can affect percent rejection.

  • Page 29: Motor Overload Shutdown

    TROUBLESHOOTING MANOWNROLH Permeate piping should be of sufficient I.D. to prevent back pressure on the system. For low temperature effects, check permeate flow rate versus temperature curve in the Appendix. If adjusting pump throttling valve does not improve permeate flow rate, the RO membranes are fouled and should be cleaned with an appropriate medium.
