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 (see page 38,
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.
Use qualitatively high-grade feed
water
Warning!
Observe the following when using →feed water for the steam
sterilization:
■
Use only →demineralized or distilled water according to
→DIN EN 13060, Appendix C.
In case of non-observance, stains or damage on the
instruments can arise and the functional readiness of the
steam sterilizer can be adversely affected.
NOTICE
→Feed water which you can inexpensively produce with the
osmosis processes with MELA

satisfies the requirements on the feed water.
Exchange the door seal
If the door seal shrinks or is wavy, it is necessary to exchange
the door seal.
The consequence can be poorly sealed areas which can lead
to the leakage of steam or cause a too high leakage rate in the
vacuum test.
Open the door of the steam sterilizer and take the old door
seal out. The door seal is only inserted in the groove of the
door plate (page 11,
Fig. 2/(5)
).
Set the new door seal in the groove in such a way, that the
wider
sealing surface shows toward the chamber side
.
IMPORTANT!
Observe without fail the different widths of the sealing
surface. Only with correct seating in the groove is a
proper closing of the door guaranteed and the chamber
tight.
