After each bumping, and until the filter is cleaned, there may be a slight increase in the starting pressure. Repeat step 2 & 3 between 3 and 6 timesįiltration will resume at near the original flow and pressure.Move the bump handle down slowly until it bottoms out.Normal reading is defined as the beginning pressure when the filter is first started after cleaning or when first hooking the filter up. Bumping should be performed when the pressure on the filter increases 7-10 PSI above its normal reading. FILTER SYSTEMīumping the filter knocks all of the dirt caught on the fingers or grids in the filter off and allows it to fall to the bottom of the filter tank temporarily reducing the pressure on the filter head.

Place filter head on filter tank and secure using filter head bolts or filter head clamp depending on model.Connect union between pump and filter tank.Assemble filter base, attach pump and motor assembly and place filter tank on base.inspect strainer housing and filter tank for cracks.Inspect check valve assembly in filter tank to ensure proper operation.Check bump head mechanism for smooth operation.Inspect the Diaphragm gasket, tube sheets and tube fingers or grids for cracks or tears.filter system will ensure trouble free operation and maintenance throughout the pool season.
