SECTION I. Valve Installation.

CAUTION

This valve is available in two models for use with sand type or diatomaceous earth (DE) type pool filters. Be certain that you
have the correct model for your filter. Installing the incorrect model may cause your pump to dead head, or drain the pool when
in the backwash position.

1. Confirm correct valve is being used; DE valves for DE filters and Sand valve for Sand filters.

2. Install valve to filter by securing bulkhead nuts on valve to fittings on filter.

CAUTION

Tighten the nuts by hand only - no additional tightness is required.

3. Plumb pump piping to center pipe in valve.

4. Plumb return and waste lines.
