The High Temperature Decontamination option is designed to heat the internal chamber to
120°C, maintain that temperature for 4 hours, and then allow the chamber to cool down to
37°C or the programmed temperature (if different from 37°C) when normal control takes
over. The cycle is designed to decontaminate all internal surfaces and components with the
exception of the Oxygen control sensor where supplied.
9.1 Using High Temperature Decontamination
1. The incubator should be cleaned, decontaminated chemically and dried
thoroughly before starting the cycle (follow the instructions for Cleaning in
Section 5).
2. The black protective cover must be removed before starting a cycle (the white
porous cover can remain in place). The shelves, shelf racks, humidity tray and
silicone rubber suction cups should all be in place during the cycle. If the
Humidity Tray Warning Option is fitted, ensure the sensor is placed on the
bottom shelf prior to starting the cycle. This is to protect the sensor from the
direct heat at the bottom of the incubator. The incubator MUST be clean and
dry, and the humidity tray MUST be empty, clean and dry, to continue. If it is
not, permanent damage can occur to the incubator that may void your warranty.
3. To start the cycle, press the
USER
menu button, select
DECONTAMINATION
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 9.2 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.
