We recommend that union remains <br /> together when gluing to insure that glue or cleaner does not ruin O-ring or sealing surface <br /> of union. <br /> SERVICE <br /> Service of filter screen is dependent on usage as every system is unique in its own <br /> way. If filter has been installed without the benefit of our Service Alarm Switch it will be <br /> more difficult to determine when service of filter screen is needed. It should be inspected <br /> at least every time the periodic pumping of septic tank and pump chamber is done. <br /> Check your local health dept. for these recommendations. <br /> If the screen becomes dogged before the periodic pumping requirements, a high <br /> level alarm or light could indicate to you the need for service of screen. If system is <br /> equipped with a 'pump on lighr and light stays on longer than normal, this may indicate <br /> need to service filter screen. <br /> To service filter screen unscrew the 4' cap with our specially designed wrench which <br /> has a 3 ft. reach and locks onto cap so as not to lose it in the tank. Top of cap has a <br /> 2' square head and any wrench that opens up to this size will work but not to the <br /> convenience of the specially designed wrench. Pull fitter screen from canister and wash <br /> out thoroughly using the proper location and proper protection in doing so. In some <br /> cases an additional filter screen allows quicker service and the dirty filter can be washed <br /> later at the shop. <br /> If the system is equipped with our Service Alarm Switch, the filter screen does not <br /> need service until the Service Alarm Switch activates a light or audio alarm. At this time, <br /> the filter screen can be removed and cleared as previously described. <br /> SERVICE ALARM SWITCH <br /> This alarm switch is available in three pressure ranges, low head, medium head, & <br /> high head. Installation is simple, on SIM/TECH FILTER systems, remove 114' plug from <br /> base of filter chamber and connect tube fitting. Next run the tube up into the tank riser <br /> and connect to service alarm switch which can be fastened to the side of the riser with <br /> nylon strap. Run alarm wire to alarm box, here the service alarm switch can be wired in <br /> with its own alarm or with the high water alarm. <br /> Pressure adjustment is made by removing the end plug, inserting a 7/32 alien <br /> wrench. Clockwise increases pressure. One tum equals approx. 3 PSI. The low head <br /> alarm switch comes factory preset at 8 PSI and is completely field adjustable within its <br /> range (3 to 24 PSI). <br />
