OPERATION
Important Sterilization Practices
• Do Not overload chamber. Refer to "Preparation and Loading". Do not
exceed maximum loading configuration. Otherwise, inadequate steriliza-
tion could result.
• All functions of the sterilizer should be monitored to provide maximum ste-
rility assurance. We recommend using Pelton & Crane's printer to provide
a permanent record of actual exposure times and temperatures.
• For additional assurance that minimum sterilizing conditions have been
achieved, good sterilization practices recommend the use of a quality tem-
perature sensitive process indicator with each cycle and within each pack-
age.
• Since temperature sensitive process indicators do not integrate steriliza-
tion parameters, biological monitoring is recommended to provide further
information in detecting inadequate sterilizer performance. Biological indi-
cators can be used to integrate the various cycle parameters and indicate
whether sterilization conditions have been met in a particular cycle.
• Thoroughly clean instruments before placing them in the sterilizer. Pro-
cessing instruments with debris or blood contamination impedes steriliza-
tion and may result in staining and/or damage to instruments or sterilizer.
Use no cleaners with chlorine.
• Follow manufacturer's recomendations for the individual items before ster-
ilizing.
• Use proper sterilization and instrument handling as recommended by ADA,
CDC, AAMI, AORN and OSAP guidelines.
• Become familiar with the individual functions of the five (5) modes to en-
sure using proper sterilization cycle. Wrong mode selection or improper
loading may result in improper sterilization.
• Do Not use staples, pins or other devices which will puncture the packag-
ing material as sterility may be compromised.
• Do Not sterilize instruments while running cleaning cycle.
• Sort instruments by type of metals. Do Not mix carbon steel stainless
steel, brass, aluminum, chrome or other types of metals as plating may
occur.
• Place loose instruments on towel or absorbent paper.
• Wrapped packages Must Not touch sides.
• Place pouches with paper side down.
• Place open containers tilting downward in tray.
• Do Not attempt to sterilize long tubing as steam may not penetrate the full
length.
• Do Not wrap instruments too tightly. Inadequate sterilization may result
from improper wrapping or placing too many instruments per package.

TIENT CONTACT.
Sterilization Assurance
Clinical Record Keeping
• Review daily and weekly records to substantiate procedures taken to as-
sure sterilization.
Techniques for Sterilization Assurance
• Use internal sterilization process indicators inside all sterilizer loads to
verify gross heat penetration.
• Once per week, use a biological spore test indicator (BI) designed for gravity
steam sterilizer operating at 121°C (Attest®, Biological Monitoring Sys-
tem, 3M, St. Paul, MN; or equivalent) or 134°C (EZ Test, Bozeman, MT)
to test each type of cycle used at your facility.
- Load sterilizer to maximum load used at your facility.
- For "Wraps" and "Packs" Cycle, place biological indicator inside wrap or
pack containing instruments and then place this pack or wrap in front
lower tray of the sterilizer. (This is the cold spot, i.e. lowest temperature
condition.)
- For Unwrapped Cycle, load trays with instruments, place biological indi-
cator in front lower tray of sterilizer.
- For Liquids Cycle, suspend self contained biological indicator into liquid
in flask using string and tape. Place this flask in front lower tray of steril-
izer.
! CAUTION: ANY LIQUIDS THAT ARE STERILIZED IN THIS UNIT ARE
FOR LABORATORY USE ONLY AND NOT FOR USE IN DIRECT PA-
TIENT CONTACT.
Follow manufacturer's instructions for using all test materials and main-
taining good clinical records.
• Follow Maintenance schedule on page 24 to ensure proper operation of
the autoclave.
• Note: Indicator tape should not be used as a sterilization indicator. It
has a temperature sensitive stripe that changes color with tempera-
ture only.
Preparation and Loading
• Clean and dry items thoroughly.
• Properly seal items in wrap or pouch if load is to be kept sterile during
storage. Recommended wrap/pouch materials are cloth, paper, or pa-
per/poly pouches. Nylon pouches/tubing are not recommended.
• Place temperature sensitive process indicator inside package.
• Place temperature sensitive indicator in front portion of bottom tray.
• Place load on tray with space between instruments or packages so that
steam can flow between items.
• Place trays in chamber with adequate space for steam circulation.
The Following are recommended maximum loading configurations:
Wrapped/Unwrapped Cycle
• Model AE: Total weight not to exceed 600 grams. This is equivalent to
approximately 9 handpieces or hinged instruments (average weight of
65 grams) or 30 hand instruments (average weight of 20 grams)
• Model AF: Total weight not to exceed 850 grams. This is equivalent to
approximately 13 handpieces or hinged instruments (average weight
of 65 grams) or 42 hand instruments (average weight of 20 grams)
Pack s Cycle
NOTE: When calculating maximum load, use the same weight and
instrument equivalencies as specified in the "Wrapped/
Unwrapped"cycle.
• Model AE: Total weight not to exceed 600 grams. One (1) pack in top
tray and one (1) in bottom tray with pack dimensions not to exceed 5"
x 7" x 1/4" .
• Model AF: Total weight not to exceed 850 grams. Two (2) packs in top
tray and one (1) in bottom tray with pack dimensions not to exceed 5"
x 7" x 1 1/2" .
Liquids Cycle*
• Model AE: Three (3) 125 ml or one (1) 250 ml glass flask(s) or bottle(s)
no more than 2/3 full.
• Model AF: Three (3) 500 ml glass flask(s) or bottle(s) no more than
2/3 full.
* Only use "4 Liquids" mode for sterilization of liquids. Using other
modes could cause the liquid to boil over that could result in con-
tamination of the water system, corrosion of the chamber and tub-
ing, clogged filters and valves or cause scalding to the operator.
! CAUTION: ANY LIQUIDS THAT ARE STERILIZED IN THIS UNIT ARE
FOR LABORATORY USE ONLY AND NOT FOR USE IN DIRECT
PATIENT CONTACT.
• Dental Handpieces: Check handpiece manufacturer's recommen-
dations for appropriate sterilization conditions. Use "2 Wrapped"
program only if handpieces are able to withstand 134°C - 137°C tem-
peratures.
• Close and latch door.
• At start of day, depress "Power"
system.
• Insure proper mode is selected for load to be sterilized.
• Add distilled quality water (water with 0-5 PPM dissolved sol-
ids) to bottom of filler cup opening. Ensure water is covering
condenser coil for proper operation. Add distilled quality water
(water with 0-5 PPM dissolved solids) to reservoir between cycles
if "Low Water"
light is on.
Operating Steps
• Depress "Clear/Start"
steam pressure while expelling air; sterilize for selected time; vent
and dry for the programmed drying time.
• Open door and unload after drying cycle is complete: Ready light is
on; five beeps occur; zero (0) pressure indicated in upper display
window and "End" is displayed in lower window if door is not opened
prior to completion of drying cycle.
• Note: Do not run sterilization cycle with drying until the unit has
preheated for 30 minutes. Otherwise, inadequate drying may oc-
cur.
• Note: Sterilized items may be removed any time during the drying
cycle. Use caution as items may be hot and wet. Wet items will not
remain sterile for any length of time.
• Important: Examine each pouch before and after the steriliza-
tion cycle for open seals or tears. If there is a breach of pouch
integrity, reseal in a new pouch and resterilize.
• CAUTION: "5 Special" temperatures set below 121°C should not
be used for sterilization, but for disinfection only.
! DANGER: Do Not attempt to open door with pressure in the cham-
-16-
ber. Avoid direct contact with hot chamber walls or sterilized load.
Use metal handle and gloves.
