The control unit includes an arrangement for supporting the collector, chamber valving apparatus aligned with the conduits and operable to compress them so as to prevent liquid flow, releasable solenoid-and-latch apparatus for preventing operation of the valving apparatus, and electrical timing circuitry for releasing the releasable apparatus in a predetermined sequence.
