Parts Diagram Overview
This section provides a visual overview of the Hayward Pro Series Plus sand filter components. The main diagram illustrates an exploded view of the filter tank and its internal and external parts, each identified by a reference number. Key components include the top closure dome, flange clamp, filter tank, top diffuser, elbow assemblies, laterals, and air tubes.
Additional diagrams show specific assemblies:
Folding Lateral Assembly (Diagram A)
This diagram illustrates the assembly of the folding laterals, which are crucial for efficient water distribution and filtration within the sand filter. It shows multiple lateral arms extending from a central hub, designed to fold for easier installation or removal.
Drain Cap Kit
This diagram depicts the components of the drain cap kit, typically including the cap itself and associated O-rings or seals, used for draining the filter tank.
Pressure Gauge Assembly
This diagram shows the pressure gauge, which monitors the internal pressure of the filter, along with its connection points, including a relief valve/gauge adapter and O-rings.
Vari-Flo Valve Assembly
Two diagrams illustrate different valve assemblies. One shows a multi-port Vari-Flo valve with various ports for different filter operations (filter, backwash, rinse, waste, recirculate, closed). The other shows a slide valve assembly. Both are depicted with their respective connections to the filter tank.
