3. To start the cycle, press the
USER
menu button, select
DISINFECTION
and press
START
. The incubator will then prompt:
IS CHAMBER CLEAN & DRY?
Answer
YES
if it is clean and dry. The cycle will start automatically. If the incubator is fitted
with a Humidity Tray Warning System, the incubator will ask two more questions:
(1)
IS HUMIDITY SENSOR ON
LOWER SHELF?
Answer
YES
to continue; (2)
IS
CABLE OFF BASE?
Answer
YES
to begin the cycle. If the incubator is fitted with
Oxygen Control, the incubator will also prompt:
IS O2 SENSOR REMOVED?
Ensure
the O
2
sensor has been removed and answer
YES
to begin the cycle. Refer to
Section 8.3 for the O
2
sensor removal/reinstallation procedure.
4. To cancel the cycle, press
CANCEL
. The incubator will cool down to the
programmed level where normal control takes over.
NOTE:
In the unlikely event of a scheduled AutoZero beginning just prior to a
disinfection cycle, the AutoZero will abort until the cycle is complete. A
user initiated AutoZero will also abort but will not resume after
completion of the disinfection cycle.
5. If the incubator door is opened during a disinfection cycle, the process will continue
as normal but will cause a failure message if the temperature falls as a result during
the heating phase and especially during the disinfection phase.
WARNING!
The door should NOT be opened during the cycle due to the hazardous
high temperatures involved. Serious burns could occur if the door is
opened during the cycle.
NOTE:
The chamber walls and CO
2
sensor all achieve temperatures of between
120 - 150°C, particularly in areas that are inaccessible to chemical
disinfection. Certain areas of the glass door and inner door seal surface
temperatures will be somewhat lower than 120°C.
6. After completion of the process, one of the following status messages will be
displayed.
If the cycle:
• was completed successfully,
DISINFECTION COMPLETED
OK
is shown.
• was cancelled by the user,
DISINFECTION WAS ABORTED
is shown.
