All American 25X-120 - User Manual

FAILURE TO FOLLOW INSTRUCTIONS AND/OR
IMPROPER USE MAY RESULT IN SCALDING,
BODILY INJURIES OR EXPLOSION.
When using the pressure steam sterilizer, basic
safety precautions should always be followed:
1. Read and understand instruction manual before
operating unit.
2. Do not touch hot surfaces. Use handles and pot
holders.
3. Close supervision is necessary when the
sterilizer is used near children.
4. Extreme caution must be used when moving a
sterilizer containing hot liquids.
5. Do not use the sterilizer for other than intended
use.
6. Always check the pressure release devices for
clogging before use.
7. This sterilizer operates under pressure.
Improper use may result in scalding injury.
Make certain unit is properly closed before
operating. Read Operating Instructions.
8. Never loosen wing nuts until the steam pressure
gauge registers zero and you have allowed any
remaining pressure to escape by opening the
control valve (lever in the vertical position).
9. Do not open the sterilizer until the unit has
cooled and internal pressure has been reduced.
Gauge should read zero at this time. Read
Operating Instructions.
10.Never use the sterilizer for cooking or
processing food.
11.Never place oil in or on this sterilizer.
12. Do not subject your sterilizer to sudden extreme
temperature changes, as this will cause
expansion or contraction which can crack a cast
aluminum utensil. Do not move a sterilizer from a
cold storage area directly onto a hot flame or
element. Do not add cold water to a sterilizer
which has boiled dry and is still hot. Do not cool
the sterilizer suddenly by pouring cold water on it
or wrapping cold wet towels around it.
13. Always operate sterilizers on surfaces that will
not be damaged by heat. We recommend the use
of our support base. See page 5, item 6.
14. As in all clinical laboratory settings, wear safety
glasses when attending to your sterilizer.
