SYSTEM INSTALLATION LC Manual 11/02 Rev. 3 Ground the power cable to the ground connection in the motor starter housing box. Branch circuit conductors supplying the motor shall have an amperage capacity of not less than 125% of the motor full load current rating as defined by the National Electric Code. 2.5 WATER REQUIREMENTS The inlet water supply must be adequate to provide the minimum flow requirement shown in the Product Description/Equipment Specifications in the Appendix. The inlet line should be sized to deliver this flow with a recommended pressure of 25 psig at the RO unit. A shutoff valve within 10 feet of the unit and a cleaning connection should be provided. A sample valve for checking feed water quality is located upstream of the prefilter, thus ensuring a true feed water sample. 2.6 PRODUCT LINE At a minimum the field installed product line should be the same size as skid mounted product discharge from the RO system. In some cases it may be necessary to increase to the next pipe size to ensure against excessive pressure loss in the product to storage tank or point of use piping. A sample valve is located in the product line to facilitate sampling the quality of the product water. A flowmeter is supplied with the unit to continuously measure the product flow. The flowmeters supplied are fluid calibrated to obtain accurate flow measurements. Any replacement flowmeter should also be fluid calibrated. 2.7 RESERVOIR (OPTIONAL) RO systems are designed to produce a constant supply of purified water. The membranes must be maintained in an operational or standby state to retain full effectiveness. Therefore, a reservoir is usually required, unless the system operates in direct-feed mode. The reservoir size is a function of space allocation in relation to system output. Therefore, size selection should be in accordance with this factor. USFilter can supply reservoirs of any desired capacity as an accessory to the basic RO system. 2.8 ACCESSORY SENSORS (PRETREATMENT INTERLOCK, CHEMICAL FEED 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 CHEMICAL FEED SYSTEM OUTPUT accessory is connected between terminals 29 and 30 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. 2-2 USFilter
LC Manual 11/02 Rev. 3 SYSTEM INSTALLATION 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; for CHEMICAL FEED SYSTEM OUTPUT connect the wires from the chemical feed system relay (by others). 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 four 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. 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. USFilter 2-3
