Parts Diagram Overview
This section provides a visual representation of the Hayward Pro Series Plus sand filter components. The main diagram illustrates the filter tank with various numbered parts, indicating their positions and relationships within the assembly. Key components include the top closure dome, valve assembly, internal piping, laterals, and drain cap.
Main Filter Assembly Diagram
A large central diagram depicts the sand filter tank in a cutaway view, showing internal and external components. Numbered callouts point to specific parts:
- Top Section: Includes the manual air relief cap (1), O-ring (2), top closure dome (3), valve/tank O-ring (4), and flange clamp (5). The top diffuser assembly (7) is shown connected to the internal piping.
- Internal Components: The main filter tank (6a/6b) houses the top elbow assembly (8), bottom elbow assembly (9), and lateral assemblies (11a/11b). The folding umbrella lateral holder assembly (12a/12b) is central to the laterals. Air tubes (13a/13b) and an air tube lock screw (14) are also indicated.
- Bottom Section: Features the filter support stand (16) and the drain cap kit (15a/15b) with the bottom drain screen.
- Side Views: Separate diagrams show the Vari-Flo Valve Assembly (20a/20b) and Slide Valve Assembly (20c) with their O-rings (21) and pressure gauges (22).
Detailed Component Diagrams
- Folding Umbrella Lateral Assembly (Diagram A): Illustrates the structure of the folding laterals, which expand like an umbrella for efficient filtration.
- Drain Cap Assembly: Shows the drain cap (15b) which includes a gasket and screen, designed for easy draining and maintenance.
- Pressure Gauge: Depicts the pressure gauge (23) with its relief valve/gauge adapter assembly (24) and O-ring (25), used to monitor filter pressure.
