Hazardous pressure. Can cause severe injury or major property damage from tank blow up.

Release all pressure and read instructions before working on filter.

INITIAL START-UP

Be sure pump is OFF before starting procedure.

Do not operate these filters at more than 50 PSI (345 kPa) under any circumstances!

To prevent serious damage to the element fabric, NEVER run you DE filter without a diatomaceous earth precoat!

To avoid damage to internal filter components, never change handle position on control valve while pump is running.

1.Make sure all clamps are in place and knobs are securely hand-tight.

2.Set valve to 'filter' position.

3.Fill trap on pump with water.

4.Open air release valve on top of filter assembly (Key No. 3, Page 14).

5.Start pump to purge air from system.

6.When steady stream of water comes from air release valve, close the valve.

7.To prepare precoat slurry, mix diatomaceous earth (DE) and water. See Table IV or instruction decal on filter shell for amount of DE to use.

8.Empty slurry slowly into skimmer to precoat filter element with an even filtering cake.

Close valve before air is drawn into system.

NOTICE: To avoid bridging between filter grids, do not use more DE than 0.1 pound per square foot of filter area (0.49 kilos per square meter).

After filter is operating, record filter pressure gauge reading in owner's manual for future use.

NOTICE: When installed on a newly plastered pool, after approximately 48 hours of operation disassemble filter and clean out plaster dust (see "Manual Filter Cleaning Procedure", Page 10).

To avoid severe injury or major property damage, exactly follow in- structions under "System Disassembly/Assembly" (Page 8)!

Remove and thoroughly clean filter element assembly. Use cleanser or deter- gent and a bottle brush to remove plaster dust (see Figures 8 and 9, Page 10).

When installed on a pool with vinyl liner or painted bottom, thoroughly back- wash and clean filter element after 48 hours of operation to remove construc- tion debris (see "Filter Backwash Procedure", Page 9).
