6.16 Emergency
Manual Exhaust
Important: Air pressure to the air manifold is required for this
procedure. Air manifold is located on top rail of plumbing stand (in
service area).
If a power failure should occur in the facility, or the sterilizer should
cease functioning, it may be necessary to manually exhaust the
sterilizer chamber. The sterilizer chamber should only be manually
exhausted if there is an immediate, critical need for load contents.
Tools Required: Small, flat blade screwdriver (1/8" [5 mm] tip).
NOTE: The emergency exhaust procedure is not feasible without
access to service area. Service area access is necessary to manually
activate air manifold switches.
1. Look at chamber and jacket pressure gauges on front panel of
sterilizer to determine if chamber is pressurized or is holding
vacuum.
2. If chamber gauge indicates pressure, activate switch V3 on air
manifold. If chamber gauge indicates vacuum, activate switch
V1 on air manifold.
WARNING – BURN HAZARD:
• Steam may be released from
the chamber when door is
opened. Step back from the
sterilizer each time the door is
opened to minimize contact
with steam vapor.
• Sterilizer, rack/shelves and
loading car will be hot after
cycle is run. Always wear
protective gloves and apron
when removing a processed
load. Protective gloves and
apron must be worn when
reloading sterilizer following
the previous operation.
