SECTION 3
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.
When the Function control is in the Power Off position, all electrical power is off and the door cannot be
operated. An additional safety interlock is included to prevent the door from being opened when there is
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
is safe to open the autoclave door. When the Function control is in the Fill position, water flows from the
reservoir into the chamber. When the water level indicator in the chamber is covered, the Function
control should be turned to Sterilize to stop the flow of water. To generate steam, the door must be closed
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 the Time control returns to “0.”
B.
When the sterilizing procedure is complete, the Sterile light will illuminate and the chime will sound. When
the buzzer sounds, turn the Function control to Vent to cut off the Sterile light and the buzzer. Steam
and unused water will then be returned to the reservoir from the chamber and pressure inside the chamber
will be reduced to near zero. When the chamber pressure reaches a safe level, the Open Door light will
become illuminated.
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
energized. Leave materials inside the chamber until dry. Drying time is determined by the size of the
material and manner in which it was packed. Drying times have not been established due to varying
conditions. When the Function control is left in the Vent position, the Magna-Clave will remain in a warm,
standby condition.
II. OPERATING PROCEDURES FOR NORMAL 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 to Vent 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.
A. Unlock door
Turn Function control to Vent or Fill. Depress and hold Open Door
button on front of Magna-Clave and lift door locking handle on right side
of unit.
B. Fill
Turn Function control to Fill. When water in chamber covers water
level indicator, rotate Function control to Sterilize.
Note: Ensure wa-
ter level indicator is completely submerged in water.
C. Load
Load chamber. Refer to Section 2-III.
