Typical Circulation Pump VACUUM amp PRESSURE LEAKS All vacuum and pressure leaks in the filtering system must be eliminated immediately after occurring Air allowed into the filter system from the vacuum side of the circulation pump will cause premature wear and physical erosion to the heat exchanger and water pip ing inside the heater Air turbulence will cause the wa ter pressure switch to malfunction Pressure leaks on the filtering system will allow the sys tem to lose vacuum and cause the water in the filter and piping to back siphon or reverse flow through the sys tem when the circulation pump is off Reverse flow may cause the water pressure switch to malfunction CHLORINATORS See chlorinator placement and chemical use guide lines 16 FILTER CLEANING amp CARE Your filter system should be cleaned at least twice a month See manufacturer s directions for proper filter cleaning methods Size and conditions may require you to clean the filter more often A filter is considered dirty whenever it restricts the flow rate by 10 or more You can use the pressure gauge on the filter tank to de termine a restriction in the filter due to clogging After the filter has been replaced or when it is new you should record the actual operating pressure with a clean fil ter When the pressure increases more than 5 p s i the filter should be cleaned If the pressure does not return to normal you must replace it Make
