i) Steam Penetration Test
The ‘steam penetration test’ should be performed on a daily basis to
confirm that the unit is operating correctly.
Run Cycle ‘C2ii’ - vacuum cycle for Steam Penetration test
Following this test, the TST should change to a uniform
purple colour. If the test pack TST is NOT of a uniform
colour check the door gasket and vessel. If the pack fails
to change correctly repeat the test. If the unit fails the
test seek technical assistance.
ii) Vacuum system leak test
The ‘vacuum system leak test’ checks the integrity of the vacuum
system.
Set autoclave in ‘standby’ by pressing ready button (B). LED next to
button (B) will illuminate.
Press and hold button (G) for 6 seconds. The display (L1) will begin to
count-down from 4 seconds. Hold button (G) until the count-down
reaches zero. The test will then start.
During the test, the segments of the cycle status graphic (L4-8) will
flash.
The test will take approximately 15 minutes. On completion the printout will advise if the unit has passed/failed the test. If a fail occurs
clean the gasket and re-perform the test. If the unit repeatedly fails
contact your equipment dealer.
iii) Auto-cycle Start
The unit can be programmed to enable any cycle to be started at any
time of day when the unit is unattended. This option is recommended
particularly when the operator performs an ‘Air leak detection test’.
• Set autoclave in ‘standby’ by pressing ready button (B). LED next to
button (B) will illuminate.
• Press and hold button (E) for 6 seconds and release. The ‘time
display’ (L1) will flash. the default time of 06.30 will be shown.
• Press (F2) to accept. If another time is required for the auto-cycle
start, change minutes then hours; by pressing button (E) up and
(F1) down and button (F2) to accept.
• The unit returns to the ready mode and the ‘time display’ (L1)
continues to flash. You can scroll through the settings as a check.
• Select the required sterilizing cycle using buttons (G), (H), and (I).
• Press the start button (C). The ‘start’ LED (C), the ‘door’ LED (D)
and the ‘time display’ (L1) will flash.
• The selected cycle will start when the programmed start time is
reached.
• To abort a timed cycle press the standby button (B).
Note: If the unit is used in a very cold environment, water vapour may
be seen coming from the cooling fan. This is normal and will only last
for a few minutes.
