Compressed air connection
(only MELAquick 12+)
A compressed air connection is intended for MELA
quick
12+.
Connect a free end of the compressed air hose (Ø 6 mm) to the quick
coupling piece of the sterile filter pre-fitted to the steam sterilizer and the
other end to the on-site compressed air supply. A coupling connector (NW
7.2) is included in the scope of delivery of the steam sterilizer. Do not
remove the sterile filter pre-fitted to the steam sterilizer.
Danger
DIN EN 13060 prescribes that the steam sterilizer may not be operated
without the sterile filter integrated in the compressed air hose.
The externally provided compressed air must meet the following
conditions:
Dried, condensate free, oil-free and filtered with a filter fineness
≤
2 µm
Pressure range 3 ... 8 bar (43.5 ... 116 PSI)
For hose lengths greater than 4 m the minimum pressure must be
4 bar (58 PSI).
Standard volume flow 10 l/min. This is taken from the supply only
during drying.
For the connection of the compressed air hose, different manifolds and
coupling plugs are available as optional accessories (see
Appendix A -
Accessories
).
Danger
If the steam sterilizer issues Error 42 "Drying - drying pump" or is a
program is aborted without the compressed air supply having been
completed at this point, the program is viewed as not having been
completed successfully.
■ In such a case, the Universal-Program must be performed five times
without a load (alternatively, three times with activated additional
drying). Drying may not be aborted. Only then is the steam sterilizer
ready for operation.
■ The steam sterilizer can only be operated correctly with a
permanently-connected compressed air supply.
■ Ensure that the compressed air supply shut-off valve is open before
every program start.
Danger
■ If the steam sterilizer is operated without a compressed air supply,
the stopper set to disable the drying (art.-no. 30986 included in the
scope of delivery of the steam sterilizer) must have been installed
before commissioning the steam sterilizer.
■ To install, follow the "Instructions for deactivating the drying
function".
■ If the steam sterilizer is operated without a compressed air supply, in
lacking a drying function, it does not conform to DIN EN 13060. The
steam sterilizer no longer corresponds with the intended use
described in the operating manual!
Attention
■ According to DIN EN ISO 7396-1, the steam sterilizer may not be
connected to the supply network for medical compressed air, e.g.
medical air technology.
