Overview
Overview
PL-ACC-TK is the pressure accumulator used in the feed-water line. Its air bladder cushions the pressure spikes caused by Clark Pump cycling, and a Schrader valve provides the air-charge connection.
Spectra’s Ventura Deluxe bulletin locates it between the prefilters and Clark Pump. The Ventura bulletin gives approximately 65 PSI precharge guidance, while the Newport 400 Connect bulletin gives approximately 60 PSI. These are model-specific reference values, not a universal setting or a tank pressure rating. Use the manual for the installed system and revision.
