Electro-Pneumatic Phoenix
OPERATING MANUAL
Description
The Phoenix filter is a fully automatic backwashing filter, comprising six patented filter
elements in separate pods surrounding a central inlet chamber. The discharge from each
pod is collected in a common area under the “doughnut” shaped filter cover before leaving
via a common discharge port. The central inlet chamber contains a proprietary
indexing
valve,
which operates the filter’s backwash. Backwash is controlled by the circuit board
situated inside the filter cover, which in turn powers a 24 VDC electric motor and gearbox
assembly. The motor/gearbox rotates the Indexing Valve while sequentially backwashing
each pod. A
pneumatic backwash valve
opens and closes with each indexing position.
