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.

PREPARATIONS FOR STERILIZATION
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.
