I. SAFETY FEATURES
TheMagna-Clave design offersseveral safety features
foryour protection.
A. Door Clamp Ring
Apatented door clampring provides maximum
safety by locking the entire rim of door. When
activated by the door handle, the door clamp ring
expands in diameter,allowingthedoor to open.
B. Open Door Button
Theopen door button energizesthedoor interlock
solenoid. It must be depressed before moving the
door handle up into the open position. The button is
operative only when the Open Door light is illumi-
nated.
C. DoorHandle
When door handle is in down position, the door is
locked and the rim is completely sealed. When
door handle is in up position, the door clamp ring is
expanded. Toopen door,move door handle to
upwardposition by the followingmethod:
·Ensure that Power On light is illuminated
·Open Door light must be illuminated
·DepressOpen Door button
WARNING: Do not attempt to move door handle
upward until:
·Open Door light is illuminated
·Pressuregaugeindicates‘0’
·Function is in Vent or Fill position
D. RelayControl
The relay controls supply power to the main heaters only when proper start up procedures have been
followed. It senses when the “Door Open” light is on and power is made available to the main heaters for
normaloperation.
·Overheat protector:If unit trips the overheat protector, the main heater is removed by relay controls
andcannot be restored withoutgoing through thestart-up procedure.This insures when thesterilization
cycle is interrupted by an out of water condition or similar failure, the Magnaclave will remain off until
the operator restarts the cycle.
·Main Heater: The timer activates the relay controls at the end of the cycle.Power is removed from the
main heaters and the buzzer notifies the operator that the sterilization cycle is completed.The buzzer
will continue to sound until the operator turns unit to vent.With the heater power removed the
Magnaclave will start cooling down.For proper drying of the contents, the unit should be vented within
15 minutes of the completion of the cycle.
·Fail Safe Operation: In the event of a power failure, the power to the main heaters is removed by the
relay control if there is an interruption to the incoming power.The heater will remain off until operator
restarts the unit.

Ill. ELECTRICAL REQUIREMENTS
The Magna-Clave requires 5000 watts at 208 volts or 220-240 volts, 50-60 cycles, single phase. Line voltage
mustbespecifiedwhenordering. Anoutletboxwithconduitknockouts,groundingscrewandacoverisprovided
on the rear of the sterilizer. This outlet box is used for connecting a power line to the Magna-Clave.
IV. CONTROLS ANDINDICATORS
A. Indicator Lights
1. Power On - The Power On light indicates thatelectrical
power is being supplied to the autoclave. It is illumi-
nated when the Function control is in the Fill, Sterilize
or Vent position. When the Power On light is illumi-
nated,thewallheatersofthe autoclave are energized to
maintaina warm, standbycondition.
2. Heat On - The Heat On light indicates that electrical
power is being supplied to the main heating elements
whichgeneratesteaminsidetheboiler. Whenthe Func-
tioncontrolisintheSterilizepositionandthedoorhandle
inthe down position (doorlocked),theHeat On light will
beilluminated and themain heating elementsare ener-
gized. Thelight remains illuminateduntilthesteamtem-
perature inside the chamber reaches the setting on the
Temperature control. The main heating elements will
cycleoff-and-on to maintain thedesired temperature.
3. Sterile - The Sterile light isilluminatedwhen:the Func-
tion control is in the Sterile position, the desired tem-
perature is reached and the Time control indicates “0.’
At the beginning of the cycle, the Time control should
be set at the desired time for sterilization. When the
Time control turns to “0,” the Sterile light illuminates
and the buzzer or chime sounds to indicate the end of
the sterilization cycle.
*Determinedby manufacturing date ofunit.
4. Open Door - The Open Door light is illuminated when
the Function control is in the Vent or Fill position and
pressureinthe chamber is lowenoughto allow the door
to be safely opened.
CAUTION:The door cannot be opened and no attempt
shouldbemadetooperatethedoorhandleuntiltheOpen
Door buttonis depressed.
B.Gauges
1. Temperature Gauge - TheTemperature gaugemeasures the steam temperature in thedischargeline
from the chamber. It is marked with a green area from 250’F to 270’F to indicate normal sterilizing tem-
peratures.
2. Pressure Gauge - The Pressure gauge measures pressure within the chamber. It is markedwith a green
area between 15and 31 PSI (pounds per squareinch).

1. Temperature Control -Temperatureandpressureinsidethe chamber are controlled bytheTemperaturecontrol.
It may be set from approximately 240cF to 270"F. Markings on the control indicate approximate settings. For a
more precise setting, refer to Section 3.
2. Function Control - All operations of the Magna-Clave are controlled by the Function control as follows:
a. Power Off - All power is turned off;door cannot be opened.
b. Fill-Waterfromreservoiris allowedtoenter chamber;wallheatingelementsare energized.
c. Sterilize - Power is supplied to all heating elements as required;door cannot be opened.
d. Vent -Unusedwaterand steaminchamberare returnedto reservoirafter sterilizing cycle is complete. The
door can be opened when the pressure decreases to a safe level and the Open Door light is illuminated.
The wall heaters remain energized. This reduces pressure build up time for successive sterilizing cycles
and promotes drying of the sterilized material.
3. Time Control - The Time control is manually set at the beginning of each sterilizing cycle. Timing begins
when the preset temperature is reached and time control counts down to “0.’
NOTE: Do not set the time control for an interval of less than five minutes.
D. Audible Signal
1. Buzzer - When the Time control returns to “0”, a buzzer will sound to indicate the end of the cycle. The
buzzer sounds continuously until the Function control is turned toVent. TheTime control must be set at
the beginning of each sterilizing cycle. If it is not set, the buzzer will indicate end of sterilizing cycle when
the preset temperature is reached, and the sterilizing cycle will not be complete. Once buzzer sounds the
main heater will turn off.
E. Water Reservoir
1. Thewater reservoir provides anample water supply for
coolingdischarged steam and water. The reservoir
should be filled with distilled or demineralized water to
pre-’ vent corrosion. It should be filled to the line marked
at the rear of the reservoir, and should never drop more
than four inches below the line. A rubber and drain hose
attached to the brass fitting beneath the autoclave
facilitatesproperdrainage and cleaning. Forinstallation
information,refer to 094075,Installationof the Magna-
Clave.
F. Stand
1. The Magna-Clave stand provides a convenient storage com-
partment to house trays or supplies.

I HANDLING AND CLEANING OF INSTRUMENTS
NOTE:Instruments must be thoroughly cleaned prior to placement in the sterilizer.
A. Handling
1. Wear heavyrubbergloves while handling instruments.Cleangloved hands with agermicidalcleaner
(iodophorsurgicalscrub).Washgloved handswellwhen instrumentshandlingis complete.
2. Transport soiled instruments on a tray to the cleanup area.Protect your hands from contact with soiled
instruments to prevent any serious infection.
3. Sort out any nonsurgical devices or other instruments that cannot withstand immersion without rusting.
Refer toTable2—1.
NOTE:Checkmanufacturer’srecommendationsforindividualitems beforeautoclaving.
B. Cleaning
Items must be completely cleaned before sterilizing. Processing instruments with debris or blood contamina-
tion may result in staining and/or damage to instruments or sterilizer.
1. Rinse instruments with hard stream of water immediately after use to remove debris. Handle soiled
instrumentsfollowingprocedure outlined in Section2-1-A.
2. Wash instruments in an ultrasonic cleaner for five to 10 minutes immersed in a fresh solution of deter-
gentand distilled ordemineralized water or a germicide solution. Followmanufacturer’srecommended
procedures.Clean all instruments inanopen position.
NOTE:For best results, use a detergent specifically designed for use in an ultrasonic cleaner with a
neutralph(7).
(Health Sonics, Pleasanton, CA;L&R, Kearny, NJ, or comparable brand).A Germicide, 2% glutaralde-
hyde or equivalent may also be used.Be sure to follow manufacturer’s instructions for mixing and use.
Otherwise,unsatisfactory results and/or damage mayoccur.Discard and replaceultrasoniccleaning
solution daily.
3. After cleaning, rinse instruments very thoroughly for 30 seconds in tap water.Then perform a final rinse
with distilled or demineralized water after the 30 second rinse to remove impurities found in most tap
water. Inspect instruments to ensure removal of all debris. Repeat cycle as necessary.
NOTE:Toprevent staining, instruments shouldbe rinsed withdemineralized(distilled) waterand dried.
After rinsing in tap water in areas with hard water (water with a high mineral/salt content), dry the instru-
ments.(Drying should not be a substitute for rinsing.)When autoclaving instruments which are not
stainless steel, use a corrosion inhibitor pre-dip for two or three minutes. (This may be 2% solution of
sodium nitrite in distilled water.) Allow the pre-dip to dry on the instruments without wiping.
4. Follow the recommendations by the instrument manufacturer on the use of lubricating products after
instrumentshave been ultrasonically cleaned.

B. Cleaning
5. With the increasing concern for asepsis, offices are using more disinfectants and instrument soaks. If
any of the disinfectants are introduced into the autoclave during the cycle (either directly or by incom-
plete rinsing after soaks), corrosion of the stainless steel chamber, instruments and trays or baskets
may occur.There are several chemicals commonly used as disinfectants which may break down under
temperature and pressure to cause corrosion to the stainless steel trays and instruments, even in a
properly passivated 304 stainless steel chamber.These chemicals include:
"AnydisinfectantcontainingZephiran Chloride (Benzalkonium Chloride), aquaternaryammonium
compound. (A number of practices still use quaternary ammonium com pounds, although this is no
longerrecommendedbyprofessionalorganizations.)
"AnyAmine based disinfectant containingquaternaryamine hydrochlorides.
"Any disinfectants containing sulfite products.
"Any disinfectants containing phenolic products. Some disinfectants commonly used in practices
containingphenolsare:
"Any disinfectants containing active hydrogen halide group.
"Sporicidin@, Lysol@, and Omni II@.
II.SPECIAL PREPARATION GUIDE FOR CARBON STEEL INSTRUMENTS
A. Handling
1. Handleand thoroughly clean instrumentsas outlined above. (Referto Section 2-1.)
B. Cleaning
1. Prepare a 2% solution of sodium nitrite (one tablespoon per quart of water). Immerse instruments in
the solution and allow them to remain for three minutes.
C. Sterilization Preparation
1. Removeinstruments and preparefor sterilization. (Refer to Section2-Ill.) Do notrinse or wipe instru-
ments prior to sterilization.
NOTE:Do not place carbon steel instruments directly on the MagnaClave’s stainless steel tray. Before
placing instruments on the tray, line the tray with a towel or paper wrap.
D. InstrumentWrapping
1. Instruments which will be wrapped for sterilization should be packaged in a material which promotes
drying.
NOTE:Instruments in packages may not dry well and may require use of an atmosphere reducer
(Vapor Phase, Lorvic Corporation, St.Louis, MO,) for best drying results.
III. TRAY PREPARATION AND LOADING
A. General Guidelines forTray Preparations
•An internal process indicator strip should be in-
cluded with each sterilizer load to verify gross
heatpenetration.
•A biological spore test indicator should be used
weeklyin a representative sterilizerload for ster-
ilizationassurance.
•Date packages and re-sterilize after one month,
oraccording to packaging manufacturers’speci-
fications.
•Sterilizationindicators/monitorsshouldbeplaced
in the front bottom area of the sterilizer.
•DO NOT mix or cause contact of dissimilar met-
als (i.e. metals such as carbon steel and stain-
less steel) during sterilization or storage.
•Makesurethatall instruments are sterilized inan
openposition.(Referto AORN guidelines.)
•Place all sharps (scissors, knives, skin hooks) so
theydonottouchduringautoclaving. Cottonor gauze
may be used to isolate and protect the sharp edges
and the smaller instruments.
•Donotplace metal instruments, other thanstainless
steel,directly on stainless steelautoclave trays. The
trays should be lined with thin cloth or paper liners.
•Anyitemwhichmightholdwatershouldbeplacedso
the water will drain out.
•Usesmallpacksto separate largerones.Seeinstruc-
tionsforpreparing wrapped trays.
•Neverstack trays on topofone another.At least one
inch should separate trays.
•Wrapped trays and packs must not touch the sides
of the sterilizer.
•Donotoverloadtrays.Overloading may cause steril-
izationfailure.

OPERATIONS
WARNING: Do not attempt to bypass any of the safety interlock systems described below. Failure to do
so could result in personal injury.
I.GENERAL
A. Whenthe Function control is in thePower Off position, all electricalpower is offand the doorcannot be
operated. Anadditional safety interlock isincluded to preventthe door from beingopened when thereis
an unsafe level of pressure in the chamber. Another interlock prevents the main heaters from becoming
energized to generate steam unless the door is fully locked. The Open Door light will illuminate when it
issafe to opentheautoclave door. When the Function controlis in the Fill position,waterflowsfromthe
reservoir into the chamber. When the water level indicator in the chamber is covered, the Function
controlshouldbeturned to Sterilize to stop the flow ofwater. Togeneratesteam, the door must beclosed
and locked. The Time control should be set at the beginning of the sterilizing cycle. Timing will begin
when the preset temperature has been reached, and will continue until theTime control returns to“0.”
B. Whenthesterilizing procedure iscomplete,theSterilelight will illuminate andthechimewillsound.When
the buzzer sounds, turn the Function control toVent to cut off the Sterile light and the buzzer. Steam
andunusedwaterwillthenbe returned to thereservoirfromthechamberandpressureinsidethechamber
willbe reduced tonearzero. Whenthe chamber pressurereaches a safe level,the Open Door light will
becomeilluminated.
WARNING: Never attempt to open door unless open door light is illuminated and pressure gauge
indicates“0.’
To aid in absorbing moisture, the door can now be slightly opened. The chamber heaters will remain

III. OPERATING PROCEDURES FOR LIQUID STERILIZATION
WARNING: Burns and bodily injury can occur if a sterilizing cycle is interrupted or“aborted”in the follow-
ing manner:
"Autoclave has been in Sterilize mode for five minutes or more after a cold start.
"Function control is then turned toVent and Open Door light is illuminated.If this situation develops,
DO NOT open door even though Open Door light is illuminated.Wait ten minutes before attempting to
open door.
NOTE:Use only Pyrex®or stainless steel containers for liquids sterilization. Containers should only be cov-
eredwith paper caps.
A. Preparation and Sterilization
1. To sterilize liquids, follow the procedures A-F, Section 3-II“Operating Procedures For Normal Steriliza-
tion.”
B. Vent

whiledepressingOpen Door buttonon front ofMagna-Clave.
E. Drying
1. After unlocking door, allow door to stand partially open with Function control still in the Vent position.
IV. OPERATING GUIDELINES
A. The Magna-Clave may be preheated by turning the Function control to Vent 30minutesbefore the
autoclave is needed. This will allow for a faster desired sterilizing temperature.
B. Water should onlybe added to thereservoirwhen theFunction
control is in theVent or Power Off position. Demineralized or
distilled water must always be used to prevent corrosion.
The minimum water level should always reach the level
indicating mark on the back of reservoir.
C. Do not attempt to turn the Function control from Sterilize to
Fill or from Vent to Sterilize. There are mechanical stops
which prevent the Function control from being turned in this
manner.
D. Improper sterilization may result if chamber is overloaded or
toocrowded.
E. TheTime control must be set at the beginning of each cycle
to the desired sterilizing time. If the Time control is not
properly set, the buzzer or chime will sound and the Sterile
light will illuminate. This indicates the end of the sterilizing
cycle, and will not allow completion of the cycle.
NOTE: Do not set the Time control for an interval of less
than five minutes.

II. CLEANING
It is highly recommended that the autoclave be cleaned a minimum of once a week with Omni-Cleaner (Part No.
WZI-091295)anddistilledordemineralizedwater.TheOmni-Cleanerisamildlyalkalineconcentrateusedtoclean
anddescaleautoclaves. Minerals,especially chlorides,arecorrosivetostainlesssteel. Therefore,tapwaterwith
ahighmineralcontentshouldnotbeused. Whensterilizingsalinesolutions,it isimperative that theautoclavebe
cleanedafter each use. Withproper cleaning, the autoclavewillprovidehigherperformanceand longer life.
A. CleaningProcedures
1. Mix12 ounces ofOmni-Cleaner in one gallon ofdistilled, demineralizedwater.
2. Drain waterfrom reservoir. Refill reservoir with a solutionofOmni-Cleaner and water.(Thereservoirwill
not be full.However, the level will be adequate.)
3. Runone- 20 minute sterilizingcycle to remove allgrease and grimefromthe system. If the autoclaveis
extremely dirty, it may require a second cleaning. Do not sterilize instruments while cleaning the auto-
clave.
4. Draincleaningsolutionfromreservoirandchamber. Rinsethoroughlywithclean,mineral-freewater,and
run a rinse cycle for fifteen minutes.
5. Drain rinse solution and wipe inside of boiler thoroughly. If scale or lime deposits remain on inside of
chamber, ensure that autoclave is cool. Then clean with water, plastic or nylon scouring pads and a
nonchlorinateddetergent.
NOTE:Detergents containing chlorine are corrosive to stainless steel and should not be used. Do not
use ordinary steel wool or steel brushes on stainless steel. Pads containing metal may damage cham-
ber.
6. Refill reservoir with clean, mineral-free water. The Magna-Clave is now ready for use.
B. DrainingReservoir
1. Thereservoir drain hose islocated inside the right-handdoor of stand, nearthe top. For Magna-Claves
which do not have a stand, the hose will be located under the front edge and to the left of the unit. The
drain hose may be drained by removing it from its clip and unscrewing the tip end. The hose should be
drainedinto a 10quart capacity container. Whenthereservoiris completely drained, replace tipandclip
drain hose in place.
C. Cleaning Fill Filter
1. Pull out fill tube and filter assembly from inside of chamber and clean filter with a stiff brush and
nonchlorinateddetergent.
2. Replace fill tube and filter assembly. Make sure filter is flat against bottom of chamber. If the filter does
notlie flat against bottomofchamber,an excessiveamountofwaterwill remain in thechamberafter the
sterilizingcycles. Failure tocleanthis filter regularlywill result in excessive time to fillandventchamber.
C. Cleaning Fill Filter
1. Clean all exterior surfaces with mild detergent and water using a sponge or cloth.
2. Exterior surfacesmay be disinfected using aniodophor (Biocide, Biotrol, Inc., N.SaltLakeCity, Utah, or
equivalent),glutaraldehyde(Cidex,Surgicos,Dallas,Texas,orequivalent)orsodiumhypochlorite(house-
holdbleachdiluted1:10-1:100. Be sure tofollowmanufacturer’s instructionsformixing anduse. Other-
wise, unsatisfactory results and/or damage may occur. Do not use household bleach on interior stain-
less steel surface.
