LABEC AA9 - Manual (Page 5)

External Steam Fittings
1.
Spring loaded safety valve pre­set to operate at 138 K.P.A. with padlock.
2. Automatic air vent.
3. Pressure gauge.
4. Solenoid valve & ball valve.
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.
External Steam Fittings
1. Spring loaded safety valve pre­set to operate at 138 K.P.A. (Safety valve).
2. Automatic air vent (air vent 2).
3. Adjustable steam release valve. If autoclaving sealed items, the adjustable steam release
valve may be closed to prevent the items exploding or blowing off lids or seals when the
autoclave has completed its cycle. In this case it is desirable to allow the autoclave to
depressurise gradually before attempting to open the lid. The valve may be partially opened
to permit a gradual release of steam (dump valve 5).
4. Pressure gauge.
Internal Temperature Probes (Optional­ not on all models)
If the autoclave is fitted with two internal temperature probes. To change these probes you must
remove the side panel and unscrew the glands in which they enter the chamber. The probes are ‘K’
type thermocouple autoclave type and are connected to an external plug for monitoring by chart
recorder or computer or P.L.C. Included is two blank plugs which you can screw into the vessel if
you do not wish to use the internal probes­ be sure you use plumbers tape before screwing these
into the vessel or replacing them in the vessel.
