CAUTION 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 caps from the top of the membrane housings This is done by removing the white snap ring of the membrane housing 2 Remove the membrane bag containing the membrane element from the shipping DOX WEAR GLOVES FOR THE FOLLOWING STEPS IN ORDER NOT TO CONTAMINATE THE MEMBRANE Cut the bag open as close as possible to the seal at the end of the bag so the bag may be re used if necessary 4 Make sure that all parts are clean and from dirt Examine the brine seal and permeate tube for nicks or cuts Replace the O rings or brine seal if damaged 5 Flow directions should be observed for installation of each element into each housing Figure 4 Page 31 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 REPLACING THE MEMBRANE ELEMENT CAUTION WARNING THE BRINE SEAL MUST BE IN THE SAME POSITION FOR EACH MEMBRANE ELEMENT HOUS
