RX Manual 04/04 Rev. 6 SYSTEM INSTALLATION 2.8 ACCESSORY SENSORS (PRETREATMENT INTERLOCK AND TANK LEVEL(S) Provisions have been made for shutdown by accessory sensors, provided such sensors are equivalent to a single-pole, single-throw switch. When a shutdown condition exists, the RO system will resume normal operation automatically when the alarm condition has been corrected or no longer exists. Please refer to the steps that follow for installation instructions and locations (please refer to the RO Controller manual in the Appendix for further instruction). A. Open the controller enclosure door to expose the terminal connections. B. Dry contacts for the PRETREATMENT INTERLOCK should be connected between terminals 19 and 20 of the terminal strip. The HIGH TANK level switch input is connected between terminals 17 and 18. The MID TANK level switch input sensor is connected between terminals 15 and 16. NOTE: A normally closed switch or switches should be selected. The MC10 Controller may be used to connect one level switch to the controller (instructions are included with the MC10 manual located in the Appendix). C. To connect the accessory, remove the shorting wire where applicable and connect a single pole single throw normally closed sensor (TANK SWITCHES and PRETREATMENT INTERLOCK) between the respective terminals. It is recommended that shielded cable, properly grounded, be used to wire these sensors to avoid radio signal interference with these functions. 2.9 SETTING THE FLUSH CYCLE TIME AND DURATION Refer to the MC10 RO Controller manual in the Appendix for detailed instructions. 2.10 BEFORE POWER TURN ON CAUTION CAUTION CAUTION If an isolation valve is located downstream of the RO unit in the product, reject or autoflush piping, a pressure relief device must be installed to avoid an over pressurization condition that could irreversibly damage the RO unit and related components. Verify that all retaining “U” pins are in place on the RO pressure vessels before turning on the pump. Be sure the product water will not enter the user system during startup. The RO system must be operated for 24 hours to flush out the preservative solution before connecting to the user system. Once the feed water is plumbed to the system and the electrical power is connected, the electrician should verify correct motor rotation. USFilter 2-3
RX Manual 04/04 Rev. 6 SYSTEM INSTALLATION 2.11 INSTALLATION OF REVERSE OSMOSIS MEMBRANE(S) CAUTION CAUTION Never engage or disengage retaining “U” pins without wearing safety glasses. Never allow the RO membrane to dry out once it has been wet, or irreversible damage will result. USFilter Reverse Osmosis units are normally shipped with the membranes installed and preserved in sodium bisulfite solution. However, should the need arise, the following procedures may be followed to install membranes: A. Disconnect all tubing from all RO pressure vessel end caps. This is done by pushing in the outer ring of the quick disconnect fitting while at the same time pulling the tubing out of the fitting. B. Remove RO pressure vessels from the frame, taking care to identify their proper location(s). C. Remove all “U” pins and end caps from each RO pressure vessel. D. Remove the each RO membrane from the RO pressure vessel in the same direction in which the feed water flows through it. E. Before installing the new RO membrane, lightly lubricate the brine (chevron) seal and o-rings with glycerin or water. F. Load the RO membrane in the direction in which the feed water will flow, inserting the end without a brine (chevron) seal first. Be careful not to roll, cut or otherwise damage the brine (chevron) seals when loading each membrane. G. Replace the end cap into the RO pressure vessel end opposite from loading end. Secure the end cap with the retaining “U” pin. H. Install the end cap on the feed end and secure it with the other “U” pin. I. Re-install RO pressure vessels onto the frame in their proper location(s). J. Reconnect the tubing to all end cap tube fittings by pushing into the fitting until the tubing “locks” into place.
