top mount emaux sand filter pool and spa systems Filtration: the pressure gauge will indicate the build up of dirt in the filter. At the start of the filtration the "clean" reading slands approximately 80 kPa (12psi). Through the course of the filtration operation, the pressure in the filter will increase as it becomes dirtier. When the pressure reaches 130 kPa (20psi) a backwash operating is to be carried out. Backwash:dirt passing the filter is cough in the sand bet and the dirt becomes saturated in the tank the pressure will increase. Once pressure the reaches approximately 130 kPa (20 psi) or 50% increase from the "clean" reading proceed on the backwash operation to send the dirt to waste. Backwash Operation: turn off pump, rotate the...
