Operating Instructions
IMPORTANT
Make sure the drain valve is closed. Fill bot-
tom of the sterilizer chamber with approxi-
mately six quarts of water or just below ledge
at bottom of door opening. (If water supply
is known to be hard or corrosive, a source of
treated water should be used.) DO NOT USE
DISTILLED OR DEIONIZED WATER.
1. LOAD STERILIZER: Use proper sterilizer loading
procedures when placing materials in sterilizer cham-
ber. All solid containers or instruments must be placed
so that water or air will not be trapped in them.
2. CLOSE DOOR: Grasp handle, and holding it in verti-
cal position, pull door down until bottom of door rests
in the bottom of door opening. Then rotate handle for-
ward, engaging the lower curved portion under the
horizontal rod in the casting at the bottom of the door
opening. Push handle all the way down and back until
door is locked securely in position.
3. SET EXHAUST SELECTOR: Located at center of
the control housing mounted on top of the unit, to
correct position. Unit is now ready to start. All items,
other than solutions, may be sterilized with selector at
“Instruments”. Solutions require a low exhaust. Place
selector at “Liquids”.
4. DETERMINE CORRECT STERILIZATION TIMES:
(Referring to next page for minimum required times in
the sterilization guide and times table.)
NOTE: In no case should the timer be set to less
than 15 minutes. Sterilization will not be ac-
complished in less than 15 minutes exposure
time.
5. TURN TIMER: Located at upper right front of steril-
izer. Select desired length of sterilizing period. This
turns power supply on and starts the cycle after pres-
sure-temperature combination has been reached.
Amber pilot light indicates that the timer is running.
6. When the sterilizer chamber reaches the selected
temperature, the timed exposure cycle will begin.
When the exposure cycle is completed, the electric
supply will be opened automatically. When the cham-
ber pressure gauge located at the top of the control
housing reads “0”, the door may be opened. (Release
handle and let go to avoid possible contact with re-
maining steam.) When opening the door, allow a few
seconds for steam to escape from chamber before
opening completely.
7. To assist in drying racks, release door handle after
pressure has been attained at start of cycle. Pres-
sure in chamber will keep door closed. The use of a
wire basket will provide better drying for dressings.
At end of sterilizing cycle, release door handle and
open slightly. Do not lift door to open position. This
will allow steam and moisture to escape. Allow door
to remain in this position for 15 to 20 minutes before
removing load. Small packs can be dried successfully
with this procedure. We do not recommend the ster-
ilization of large packs, such as linens. Be sure con-
densate bafes are in position in the chamber.
8. Remove load and check water level for next opera-
tion.
STERILIZATION GUIDE
• PACKS (Linens, gloves, etc.): Use wire basket
to facilitate drying. Be sure condensate bafes are
in place. Place packs on edge and arrange load in
chamber, so that only minimal resistant to passage
of steam through the load will exist. NOTE: Place
gloves in upper two-thirds of chamber.
• JARS, CANISTERS (etc.): Place containers on side
to allow for displacement of air and complete contact
of steam to surfaces. Drying is also facilitated.
• PETRI DISHES, PIPETTES, DESICCATORS (etc.):
Should be inverted.
• UTENSILS, TREATMENT TRAYS: Placed on edges
to facilitate drying.
• INSTRUMENT SETS: Place instruments set in trays
having mesh or perforated bottoms. Place trays at
on shelves.
• COMBINING FABRICS & HARD GOODS: Place
hard goods on lowest shelves.
• PLASTIC UTENSILS: DO NOT stack or nest plastic
items.
• LIQUIDS: Sterilize medium liquids separately from
other supplies or materials. Set exhaust selector to
proper position (liquids).
• SMALL ITEMS: Sterilize small items in baskets, or
trays.
