Housing parts
Where necessary, clean the housing parts with a neutral fluid cleaner or spirit.
External water storage container
Should you use the external water storage container for the feed water supply, perform regular checks and
cleaning as follows:
Interval
Upon every refill
Check the storage container for soiling. Clean any soiling before refilling
the storage container.
At least once a month
Depending on the light, ambient temperature and consumption, clean the
external water storage container to prevent the development of germs
and algae. To do so, empty the container and clean it with approx. 3 l of
warm tap water with a neutral cleaning agent and a suitable brush. Rinse
with a large quantity of tap water at least twice. Always rinse the storage
container with a litre of feed water after completing the cleaning.
Avoiding staining
Only proper cleaning of the instruments prior to sterilization enables you to avoid residue from being re-
leased from the load under steam pressure during sterilization. Loosened dirt residue can clog the filter, fit-
tings and valves of the device and deposit themselves on the instruments and in the sterilization chamber
as deposits and stains.
All steam-conducting parts of the device consist of non-rusting material. This rules out the possibility of
stain or rust development being caused by the steam sterilizer. Any rust which develops is always extrane-
ous rust.
Incorrect instrument decontamination can result in the accretion of rust even on stainless steel instruments
of leading manufacturers. Often, a single instrument which drops rust can suffice to cause the develop-
ment of rust on other instruments or in the device. Remove foreign rust from the instruments using chlo-
rine-free stainless steel cleaning fluid (see
[
page 64]) or send the damaged instruments to the
manufacturer.
The extent of stain accretion on the instruments is also dependant on the feed water used for steam gen-
eration.
Checking and oiling the door lock
NOTICE
Wear of the door lock
Only use MELAG oil.
Check and oil the door lock every two months as follows:
1.
Clean the locking spindle and nut with a non-fuzzing cloth.
2.
Insert the test gauge into the door lock nut as far as it will go
and turn it 180°. If this is not possible or resistance can be
felt, the door lock nut is worn. Have the door lock nut
replaced by an authorised technician.
3.
Put two drops of oil in the door lock nut.
Ê
The oil will be distributed automatically by closing the
door.
