Routine Maintenance
Listing of Safety Precautions
WARNING — STERILITY ASSURANCE HAZARD:
Load sterility may be compromised if the biological air removal or air leak test indicates a potential
problem. If these indicators show a potential problem, refer the situation to a qualified service technician before
using the sterilizer further.
According to AAMI standards, a measured leak rate greater than 1.0 mm Hg/minute indicates a problem
with the sterilizer. Refer the situation to a qualified service technician before using the sterilizer further.
WARNING — PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD:
Safe and reliable operation of this equipment requires regularly scheduled preventive maintenance in
addition to the faithful performance of routine maintenance. Contact STERIS to schedule preventive mainte-
nance.
Repairs and adjustments to this equipment must be made only by fully qualified service personnel. Maintenance
performed by inexperienced, unqualified persons or the installation of unauthorized parts could cause personal
injury or result in costly equipment damage.
WARNING — PERSONAL INJURY HAZARD:
Keep hands and arms out of the door opening when closing the door.
CAUTION — POSSIBLE EQUIPMENT DAMAGE:
Insufficient service clearance will make repairs more difficult and time consuming.
Piping sized too small may cause water hammer, resulting in damage to the sterilizer.
Never use a wire brush, abrasives or steel wool on door and chamber assembly. Do not use cleaners containing
chloride on stainless-steel surfaces. Chloride based cleaners will deteriorate stainless-steel eventually leading
to failure of the vessel.
After installation, it is mandatory to brace piping at the drain funnel so that it will not move vertically.
Allow thermostatic traps to cool to room temperature before removing cover. Since there is nothing to limit
expansion, the bellows may rupture or fatigue if trap is opened while hot.
Actuation at less than 75% of rated pressure can allow debris to contaminate the seat and cause the safety valve
to leak. A leaking safety valve must be replaced.
Failure to flush generator on a daily basis could result in generator malfunctions. Warranty on the generator will
be voided unless flushed daily.
Before flushing generator, ensure generator drain valve is fully open to prevent generator heaters from turning
on during flush phase.
Sterilization of chloride-containing solutions (e.g., saline) can cause chamber corrosion and is not recommended
by the manufacturer. If, however, chloride-containing solutions must be processed, clean the chamber after each
use.
