External waste water
container
Only completely empty the waste water container for cleaning.
During running operation, always ensure that the cooling hose is covered
with water when draining water.
Sterile filter
(only MELAquick 12+)
Use a ph-neutral and chlorine-free cleaning fluid to remove soiling (e.g.
dust) from the surface of sterile filter and the compressed air hose.
Check the filter medium regularly for discolouration. A light grey colouring
of the filter medium does not influence the filter performance.
Danger of injury
Other colourings or dampness in the filter housing points to insufficient
treatment of the compressed air. In this case, the sterile filter must be
replaced immediately. Check whether the quality of the compressed air
available corresponds to the requirements (see
Chapter 3 – Initial
Commissioning).
Insulating plug on the sterile
filter (only MELAquick 12+ p)
Check the insulating plug on the sterile filter every four weeks. To do so,
you can remove this using the plastic bracket and then remove it from the
bracket. If necessary, clean the insulating plug in the sterile filter with clean
water and allow it to dry before inserting.
Push the insulating plug some 2 mm over the rim of the passage into
the plastic bracket while rotating it slightly.
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.
Avoid formation of spots
Formation of spots due to
improperly cleaned
instruments
Only if you properly clean the instruments before sterilization, you can
avoid the detachment of residues resulting from loading or instrument
preparation under steam pressure during the sterilization.
Detached dirt residues (e.g. residues of disinfectants) can clog the filter,
nozzles and valves of the steam sterilizer and deposit as stains, spots or
discolorations on the instruments and in the chamber (see page 25,
Prepare items to be sterilized
).
Formation of spots due to
third-party rust
All steam-conducting parts of the steam sterilizer are made of non-rusting
materials. This excludes the formation of rust caused by the steam
sterilizer. Should rust stains occur, then we are dealing with third-party
rust.
If the instruments have been incorrectly prepared, rust can form even on
stainless steel instruments of leading manufacturers. Often a single rust-
producing instrument already suffices for third-party rust to form on the
other instruments or in the steam sterilizer.
Remove third-party rust from the instruments with a chlorine-free
→
stainless steel cleaning agent (see page 42,
Cleaning
) or send the
damaged instruments to the manufacturer for reconditioning.
Formation of spots due to
inadequate quality
of the feed water
The extent of the formation of spots on the instruments also depends on
the quality of the

feed water employed for steam production.
