This document is the installation, operation, and service manual for the Hayward H400 swimming pool pump and filter system. It details the system components, including the centrifugal pump, high-rate sand filter, and six-position control valve. The guide explains how the system works, covering the flow of water from the pump through the filter and back to the pool.
| System Type | Swimming Pool Pump and Filter System |
|---|---|
| Filter Type | High rate sand filter |
| Pump Type | Centrifugal pump |
| Valve Positions | Six operating positions and one Winterize position |
Filters should never be tested or subjected to air or gas under pressure, as this can cause severe bodily injury or property damage.
The filter should be backwashed when it becomes so plugged with dirt that the pressure rises and the flow to the pool is lowered.
The pump must always be turned off before changing the valve position to prevent equipment damage and possible injury.
