9. Check if the entire door gasket is properly inserted in the groove. The door gasket may not show any waves,
otherwise push it back into the groove using a rounded object.
10. Next, start a sterilization program without a load.
Sieve tray of the sterilization chamber
A heavily soiled sieve tray can trigger malfunction messages.
Only remove and clean the sieve tray if it is very dirty. The sieve tray prevents dirt particles from depositing in the bores
of the sterilization chamber and clogging them.
1. Make sure the sterilization chamber is clean before removing the sieve tray.
2. Use adhesive strips or the like to remove the sieve tray.
Housing parts
Where necessary, clean the housing parts with a neutral fluid cleaner or spirit.
Comply with the following specifications when disinfecting the housing parts:
n Use wipe disinfectants and not spray disinfectants. This prevents disinfectant from getting into inaccessible places or
ventilation slots.
n Only use alcohol-based surface disinfectants (ethanol or isopropanol) or alcohol-free disinfectants based on
quaternary ammonium compounds.
n Do not use disinfectants containing secondary and tertiary alkylamines or butanone.
Feed water container
1. If you use the feed water container to supply feed water, check the container for soiling before filling it with feed
water.
2. If necessary, clean the container with a cloth and fresh feed water.
Wastewater container
u Empty the wastewater container completely only for cleaning.
During operation, drain only enough water so that the cooling coil is still covered with water.
Sterile filter (only MELAquick 12+)
1. Use a pH-neutral and chlorine-free cleaning fluid to remove soiling (e.g. dust) from the sterile filter and the
compressed air hose.
2. Check the filter medium regularly for discolouration. A light grey colouring of the filter medium does not influence the
filter performance.
NOTICE
Other colourings or dampness in the filter housing points to insufficient reprocessing of the
compressed air.
n Have the sterile filter replaced immediately and check that the quality of the compressed air available
meets the requirements, see Compressed air connection (only MELAquick 12+) [}page20].
Insulating plug on the sterile filter (only MELAquick 12+ p)
1. Check the insulating plugs on the sterile filter every four weeks.
2. Pull out the insulating plug on the plastic bracket and remove it from the bracket.
3. If necessary, clean the insulating plug in the sterile filter with clean water and allow it to dry before inserting.
4. Push the insulating plug some 2 mm over the rim of the passage into the plastic bracket while rotating it slightly.
5. Place the plastic bracket in the opening in the side wall and turn it by a full rotation so that the insulating plug sits
securely in the opening of the sterile filter.
