2 Introducon
The patented Pulsar® Precision feeder creates a consistent soluon of calcium hypochlorite used for water disinfecon.
2.1 OverviewofOperaon
The Pulsar® Precision feeder operates as follows:
1. Pulsar® Plus Briquees are placed in a basket and suspended over the soluon reservoir.
2. The control box is plugged into a chemical controller output and powered on.
3. When the chemical controller requires chlorine, the feed solenoid valve opens allowing water from the pool return to enter the inlet water
manifold at the proper supply ow rate.
4. Low-velocity, high-volume water enters the reservoir and covers the boom of the basket.
5. Pulsar® Plus Briquees erode into the reservoir and create a consistent 0.7% available chlorine soluon with 84 °F [28.8 °C] inlet water
temperature.
6. The chlorinated soluon lls the reservoir, liing the oat switch connected to the discharge valve unl the valve opens.
7. The discharge valve and outlet tubing are connected to a venturi. The vacuum generated by the venturi sucon drains the reservoir tank
and sends the concentrated soluon into the pool return.
