12.3.2 Using the high temperature disinfection (Galaxy S)
Prerequisites
• The incubator should be cleaned, disinfected, and dried thoroughly before starting the cycle, (see
Disinfection/Decontamination on p. 53).
• The black protective cover must be removed (the white porous cover can remain in place).
• The shelves, shelf racks, humidity tray and silicone rubber feet and sleeves should all be in place during
the cycle.
• The incubator MUST be clean and dry.
• The humidity tray MUST be empty, clean and dry.
1. Simultaneously press the ▼ and * keys.
The display will change and the following prompt will appear: HOT. DECON CYC.LE ENT.ER STA.RTS.
2. Press the enter key to begin the cycle (or press the * key to cancel the operation). The enter key
command will only be accepted when the entire message has been displayed at least once.
When the disinfection cycle starts, the display will show another prompt: IS INS.IDE CLE.AN AND.DRY.
3. Press the enter key again (or press the * key to cancel the operation). The enter key command will only
be accepted when the entire message has been displayed at least once.
During the three stages of the disinfection cycle, the display keeps the user informed by scrolling through a
sequence of messages as shown below:
• Current chamber temperature (in C) and time remaining (hours and minutes) are indicated as 120.2.45
(i.e., 120 °C with 2 hours and 45 minutes remaining).
• Every 10 seconds, by flashing one of the following messages for one second, the display will indicate
which disinfection stage the incubator is in:
– HE.AT (heating to 120 °C)
– DEC.ON (maintaining 120 °C)
– CO.OL (cool down).
• The time displayed counts up during the heat and cool stages, but it counts down from 4 hours during
the disinfection stage. After the cool down phase is completed, the following messages will be displayed
depending on the outcome:
– DEC.ON PAS.SED
