Summary of Safety Precautions Service and Maintenance Procedures 129359-452, Volume 1
SUMMARY OF SAFETY PRECAUTIONS 1
The following is a summary of safety precautions to be observed when operating or servicing this unit. WARNINGS
indicate the potential for danger to personnel, and CAUTIONS indicate the potential for damage to equipment.
The precautions are repeated (in whole, or in part) where applicable throughout the manual. This is a listing of
all safety precautions appearing in the manual. Carefully read them before proceeding to use or service the unit.
WARNING – BURN AND SHOCK HAZARD:
Repairsandadjustments should beattemptedonlyby authorized personsfullyacquainted
with this equipment. Use of inexperienced, unqualified persons to work on the equipment or the
installation of unauthorized parts could cause personal injury or result in costly damage.
Allow sterilizer, generator (if applicable) and accessories to cool to room temperature
before performing any cleaning or maintenance procedures.
Sterilizer and rack/shelves will be HOT after cycle is run. Always wear protective gloves and
apron (also face shield if processing liquids) when removing a processed load. Protective gloves and
apron should also be worn when reloading sterilizer following previous operation.
When sterilizing liquids, to prevent personal injury or property damage resulting from
bursting bottles and hot fluid, you must observe the following procedure:
•Use LIQUIDS cycle only. No other cycle is safe for processing liquids.
•Use only vented closures —do not use screw caps or rubber stoppers with crimped seal.
•Use only Type I borosilicate glass bottles —do not use ordinary glass bottles or any container not
designed for sterilization.
•Avoid sudden full opening of door at end of cycle. Open sterilizer door no more than one inch and wait
at least 10 minutes before unloading sterilizer.
•Do not allow hot bottles to be jolted. This can cause hot-bottle explosions! Do not move bottles if any
boiling or bubbling is present.
•Allow bottles to cool to touch before attempting to move them from sterilizer shelf or tray(s) to the storage
area.
A steam supply malfunction may cause the sterilizer-chamber to fill with scalding water.
Do not open chamber door if the unit fails to complete an automatic cycle or if water leaks past the door
gasket upon unlocking the door.
WARNING – SLIPPING HAZARD:
To avoid slippery floor conditions, immediately wipe up any spillage or condensation in sterilizer
loading area.
WARNING – EXPLOSION HAZARD:
This sterilizer is not designed to process flammable liquids.

129359-452, Volume 1 Service and Maintenance Procedures Summary of Safety Precautions
CAUTION – POSSIBLE EQUIPMENT DAMAGE:
Never use a wire brush, abrasives or steel wool on door and chamber assembly.
After installation it is mandatory to brace piping so that it will not move vertically. Failure to do so may allow
p-trap to separate from the funnel.

1. Verify that the steam-to-jacket valve is closed.
NOTE: Water to sterilizer must also be turned on.
2. Open the drain valve on the side of the unit.
3. Open the water-level sight glass valves and water supply valve if they are
closed.

6. Allow the unit to flush for at least 3 minutes; then close the drain valve. The
generator will fill to the proper working level and then start to heat.
7. Open the steam-to-jacket valve slowly when the generator has reached
proper operating pressure (within 10 minutes after flushing).

Laboratory processes may require additional special sterilizer adjustments
described in Paragraphs 3.6.1, 3.8.2 and 3.8.3.
Refer to VOLUME 3, STERILIZER OPERATING PROCEDURES –LABORA-
TORYUSAGEwhensterilizerisbeingusedinthelaboratorymodeofoperation.
3.8.1 Set Sterilize Temperature Overdrive
Controlsare factorycalibratedto controlchamber temperature at3.0 F*(2C)
above the set temperature. This overdrive setting assures effective load
temperature control and provides for the shortest possible cycle time. For
special sterilizer applications this can be adjusted from 0-9.9 F.
