CAUTION: Never use a wire
brush, abrasives, or steel
wool on door and chamber
assembly. Do not use clean-
ers containing chloride on
stainless-steel surfaces.
Chloride-based cleaners
will deteriorate stainless
steel, eventually leading to
failure of the vessel.
CAUTION: Lifting the cham-
ber float switch when clean-
ing the chamber may cause
the sterilizer control to ini-
tiate a "Chamber Flooded"
alarm. If this alarm condi-
tion occurs, the operator
must turn the control power
OFF then ON to clear the
alarm. The control power
switch is located in the me-
chanical area at the side of
the sterilizer. Placing the
sterilizer in standby does
not clear this alarm.
