Sterilmatic STM-E & STM-EL Sterilizers
The compact sterilizer that does a big sterilizer job.
This little sterilizer has as much inside capacity
as many large, more costly conventional sterilizers
and up to five times the capacity of smaller tabletop units.
OPERATING INSTRUCTIONS:

1. IMPORTANT: Make sure the drain valve is closed. Fill bottom of the sterilizer chamber with approximately six
quarts of water of just bellow 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 WATER. (See page 13)

2. LOAD STERILIZER: Use proper sterilizer loading procedures when placing materials in sterilizer chamber.
All solid containers or instruments must be placed so that water or air will not be trapped in them.

3. CLOSE DOOR: Grasp handle, and holding it in vertical position, pull door down until bottom of door rests in
the bottom of door opening. Then rotate handle forward,
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.

4. 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".

5. DETERMINE CORRECT STERILIZATION TIMES: (Referring to pages 15 & 16 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 accomplished in less than 15 minutes
exposure time.

6. TURN TIMER: Located at upper right front of sterilizer. Select desired length of sterilizing period. This turns
power supply on and starts the cycle after pressuretemperature combination has been reached. Amber pilot
light indicates that the timer is running.

7. 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 chamber 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 remaining steam.) When
opening the door, allow a few seconds for steam to escape from chamber before opening completely.

8. To assist in drying racks, release door handle after pressure has been attained at start of cycle. Pressure 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 sterilization of large packs,
such as linens. Be sure condensate baffles are in position in the chamber.

9. Remove load and check water level for next operation.

............................................................STERILIZATION GUIDE

PACKS (Linens, gloves, etc.) – Use wire basket to facilitate drying. Be sure condensate baffles 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 twothirds 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 flat 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.
