9.If any DE remains on grids after backwashing, flush filter elements with garden hose to remove it. Be sure to comply with local code for waste DE disposal.

10.Follow instructions under 'Assembly', Page 8, to reassemble filter.

11.Follow 'Initial Start-up' procedure (Page 7, steps 4, 5, 6 and 7) to restart system.

12.Compare pressure reading on gauge with reading recorded after initial startup. The two readings should be very close; if not, do "Manual Filter Cleaning Procedure", below.

MANUAL FILTER CLEANING PROCEDURE

Before Disassembling Filter:

1. STOP PUMP.

2.OPEN air release valve.

3.WAIT until all pressure is released from filter tank and system before loosening clamps.

NOTICE: At least twice a year, disassemble and clean filter regardless of oper- ating pressure readings. This can be done conveniently while winterizing pool in cold climates. Use this method regularly if no means of backwashing is available.

1.Backwash filter as usual, but do not precoat.

2.Disassemble filter (see Page 8).

To avoid severe injury or major property damage, exactly follow in- structions under “Disassembly” (Page 8)!

3.Unscrew union collar holding element assembly in position. NOTICE: Be careful not to lose O-Ring.

4.Grasp element assembly at manifold (Figure 6) and remove it.

5.Hose down element assembly and clean with bottle brush (Figure 7). Use detergent solution or filter cleanser available from a pool service store.

NOTICE: To avoid damaging fabric, do not allow filter element to rub on concrete or any abrasive surface during cleaning.

NOTICE: Do not expose element cloth to direct sun for long periods. Direct sun will cause the cloth to deteriorate.

6.Inspect grid cloth for tears, calcification, plugged areas, etc. If necessary, soak element in filter cleanser to remove buildup of oils, etc. If calcified, consult pool service company or factory for instructions.

7.Thoroughly clean air relief filter screen (Key No. 2, Page 15) on top of manifold. Be sure to remove all debris from screen.

8.Inspect O-Ring out of the internal union (see Figure 6) for damage. Reinstall it in the groove in the union half if it is undamaged; if it shows tears or cuts replace it.

9.Replace filter element in tank and tighten union firmly hand tight. Union
