Table of Contents

When fitted to the autoclave this system ensures that air drawn into the autoclave during the

cooling stage of the cycle is first passed through a bacteriological air filter. This filter is fitted at

the back of the autoclave.

The filter should be regularly changed to maintain its effectiveness

Vent Filter

When fitted to the autoclave this system passes all autoclave discharge through a filter fitted

inside a pressurisable stainless steel housing. At the end of the cycle any unfiltered

condensate from the filter housing is returned to the autoclave. The correct operation and

effectiveness of the filter system should be regularly checked. Please refer to the

manufacturer's instructions enclosed with this manual.

If fitted this system continuously monitors the performance of the temperature reading and

control system with reference to an internal reference standard. If any problem is detected

with the system the autoclave is stopped and a fault is signalled. (See Warning Indicators and

Fault Codes for details.)

(Fitted as an optional extra in addition to the standard microprocessor based

overheat function)

This device acts as secondary protection against the autoclave boiling dry and damaging the

heating elements in the event of failure of the low water sensing system. Should the heater

elements ever exceed a temperature of 150

the fault code of F018 will be shown in the temperature display.

Should this occur, then the autoclave should be switched off and allowed to cool to a safe

temperature and pressure before opening for examination of the water level.

The fault indication can be cancelled as described in the Faults section. To re-run the

autoclave it should be sufficient to top up with water to the correct level. However the low

water system should be checked for faults as soon as possible and cleaned or repaired as

necessary. (See Maintenance section.)

The overheat is activated by a thermocouple mounted on one of the heating elements inside

the autoclave. This is coupled directly to the main processor board, and the overheat

temperature is factory set.

When supplied and unless previously specified otherwise the loading trolley is manufactured

for loading the lower shelf of the autoclave. The trolley is fitted with locking castors, which

can be locked in place once the trolley has been pushed into position for loading or unloading.

These hold the trolley securely in place, preventing it from rolling backwards, especially when

pulling heavy loads onto it during unloading.

Release the locking castors before pulling the trolley away from the front of the autoclave.
