Page 7: System Installation And Start-Up Procedures
SYSTEM INSTALLATION AND START-UP PROCEDURES 1. Inspect the system for any damage that could have occurred during shipment. Although all sys- tems have been individually inspected, complete a quick inspection of the fittings, tubing and other components. 2. Please provide a reasonable amount of space for installation and leave 6 inches of space below the filter housings for easy removal during maintenance endeavors. - Page 8 7. The sediment filter and carbon must be serviced regularly for optimal performance. The water quali- ty should be checked every two weeks minimum. The pre-filters should be checked once a month over the first 3 months of operation to determine the filter change frequency. Typically most appli- cations will not need to change the filters more than twice annually.

Page 13: Membrane Installation, Removal And Replacement
MEMBRANE INSTALLATION, REMOVAL AND REPLACEMENT Installation and replacing membranes in the pressure vessels is an easy process with the proper infor- mation and tools at hand. Please refer to the following instructions when removing and replacing mem- brane elements: WARNING: ALL PRESSURE GAUGES MUST READ ZERO BEFORE PROCEED- ING. - Page 14 4. Make sure that all parts are clean and free from dirt. Examine the brine seal, and permeate tube for nicks or cuts. Replace the cap O-rings or membrane brine seal if damaged. BRINE SEAL 5. Flow directions should be observed for installation of the membrane element into the pressure vessels. REPLACING THE MEMBRANE ELEMENT: WARNING: THE BRINE SEAL MUST BE IN THE SAME POSITION AS IT WAS FOR FACTORY PRE-...
- Page 15 1. Remove membrane element from the right (feed water) side of the membrane housing. Long nose pliers may be necessary to pull the old membrane element out of the membrane element housing. 2. Lubricate the membrane brine seal and cap o -rings with a non-petroleum based lubricant. 3.

Page 18: Operation And Maintenance
OPERATION AND MAINTENANCE The reverse osmosis process causes the concentration of impurities. The impurities may precipitate (come out of solution) when their concentration reaches saturation levels. NOTE: PRECIPITATION CAN SCALE OR FOUL MEMBRANES AND MUST BE PRE- VENTED. 1. Periodically observe the quality and quantity of product water from the system. NOTE: CHECK THE FEED WATER PRESSURE GOING INTO THE REVERSE OSMOSIS MEMBRANE, A SIGNIFICANT DROP IN PRESSURE COULD INDICATE A FOULED PRE-FILTER. -
Page 19: Preparing Unit For Storage Or Shipment
PREPARING UNIT FOR STORAGE OR SHIPMENT Prior to shipping or storing the system, the system should be cleaned with an appropriate cleaner, flushed with water and protected from biological attack with an appropriate solution for membrane elements. The membrane housing (s) and plumbing lines of the system must be completely drained. -
