(1) Control ON. Use this switch to energize (opened to steam supply)
8SOL. Steam enters and heats the jacket to the selected temperature by energizing
(opening) and de-energizing (closing) 8SOL.
(2) Seal door. Press the seal door switch (label "N" in figure 1-5) to
energize (opened to steam/closed to ejector) 10SOL on single door units. 10SOL
(control end) and 11SOL (remote end) are energized on double door units. The gasket
groove(s) is/are pressurized, sealing the chamber. Select the wrapped cycle and enter
the appropriate times and preset temperature.
(3) Phase 15: purge. Press the cycle start switch (labeled "P" in figure 1-5)
to (after a 5-second delay) energize 1SOL, 2SOL, and 6SOL (opened). Steam enters
the chamber from the jacket through 1SOL. It purges the chamber of air and steam
through 2SOL to the ejector. During the purge, steam and air are pulled from the
chamber by the negative pressure created by the ejector. The steam then travels to the
ejector where it is cooled by water or down the drain where it is also cooled by water.
After the time period noted, 2SOL and 6SOL are de-energized (closed) and the purge is
