*Note 3:
The wash pump
starts 6 seconds before
the fill/rinse valve closes.
The wash pump
runs for 3 seconds to
evacuate air from wash
pump before the
pumped final rinse begins.
Solid state timer control
prevents the rinse aid pump
and sanitizer pump
from running after the
fill/rinse valve closes.
Note 2:
Solid state timer control
prevents detergent pump
from running longer than
time required to fill/refill
wash tank.
