Safety Instructions
1. Use full face shield protection when loading and unloading the chamber.
2. Fill only with hose or bucket – do not connect to water mains.
3. Load or unload with gloves which cover forearms or wear long sleeve shirt.
4. If contents are harmful wear an appropriate respirator and filter to prevent inhaling
hazardous
vapors.
5. Ensure both hands hold lid handles when opening autoclave and ensure no body parts extend over
the autoclave.
6. Ensure the baskets are not too heavy when loading and unloading and use correct lifting methods.
7. Keep hands and body away from autoclave when in use to prevent burning and/or scalding.
Operation
1. Connect the chamber to an alternating current supply of voltage specified on the rating plate mounted on
the side or rear of the chamber.
DANGER: THIS AUTOCLAVE MUST NOT BE CONNECTED TO DIRECT CURRENT SUPPLY
1. Ensure the drain 1 is closed, and then manually fill the boiler with clean water to a level just below the top
of basket stand. Note: YOU MAY USE DISTILLED WATER.
2. Load the autoclave.
3. Close the lid following the “closing the lid” instructions.
4. Switch the mains power on. Turn the temperature controller to the required temperature.
5. Set the timer to the required sterilisation period. The timer has multiple time autoclave selections which
are displayed in the window i.e. 0.1 seconds, 0.1 minutes, 0.1 hours, hours, 10’s of hours. The time may
be selected in any mode from 001 to 300hrs.
6. Press the ‘start’ button.
7. The autoclave will switch on and will heat up until the preset temperature is reached.
8. When the preset temperature is reached the timing cycle will start. The red alarm light will illuminate on
the temperature controller. Constant pressure/temperature will be maintained in the autoclave until the
pre­set time has elapsed, at which time the heaters will switch off and the dump valve 5 will automatically
release the steam if it is open.
9. Open the lid following the “opening the lid” instructions. BE SURE ALL STEAM IS RELEASED FIRST.
Indicators
1. An indicating lamp adjacent to the controller will illuminate when the heaters are operating.
2. An amber pilot light will illuminate if the water level is too low.
3. An automatic digital reset timer with multiple time modes will be activated once temperature reaches the
set temperature, the timer will then flash “off” until the time has elapsed, then the autoclave will cool until
the ‘start’ button is pressed again.
4. If you wish to change the temperature you are using the autoclave at and therefore the temperature at
which the timer will begin its timing cycle please call the manufacturers technical department.
5. It is advisable to check the water level after each cycle.
Chart Recorder (Optional ­ not on all models)
Please read the chart recorder manual before use of the autoclave.
The recorder is programmed to record the autoclave temperature on Channel 1. If the recorder is remote it
should be mounted/placed adjacent to the autoclave and then using the leads from the recorder, connected
to the matching sockets on the rear of the autoclave body. When positioned and connected to the autoclave,
open the door of the recorder, place the chart paper in position and remove the white caps from the
pens(the internal door can be opened to access the pens), press the button to switch the recorder ON.
Connect the recorder to the MAINS supply and turn ON.
