The P-4000 is an AC-driven, constant-speed 8 oz pump
with a multi-time module. It is triggered by a push-button switch (mounted on top of the unit) or by an external 24-240 VAC (or 24-130 VDC) trigger signal. The
multi-time module has four operating modes (relay, recycle-timing, timed-run and timed-run with delay). In addition to acting as a relay, the multi-time module
can meter a fixed volume of chemical when triggered, with the option of setting a delay time between the trigger signal and the pump start.
