3.3 Material quality 3.3 Material quality
For the external housing MEMMERT employs stainless steel (Mat.Ref. 1.4016). The chamber is made from
stainless steel (Mat.Ref. 1.4301) which exhibits high stability, optimal hygienic properties and corrosion
resistance against many (not all) chemical compounds (care required e.g. with chlorine compounds).
The oven load has to be checked carefully for its chemical compatibility with the above materials.
A compatibility table for materials can be requested from MEMMERT.
WARNING! Always pull out the supply plug before WARNING! Always pull out the supply plug before
opening the oven cover! opening the oven cover!

•
Operating voltage see label, 50/60 Hz
• Current rating see label
• Protection Class 1, i.e. operating isolation with ground connection to EN 61010
• Protection IP20 to DIN EN 60529
• Interference suppression to EN55011 Class B
• Oven protected by a fuse 250V/15A fast blow
• Temperature controller protected by a 100 mA fuse (200 mA on 115 V)
• When connecting a MEMMERT oven to the electrical supply you have to observe any local
regulations which apply (e.g. in Germany DIN VDE 0100 with FI protection circuit)
3.5 Note on EMC (electromagnetic compatibility) 3.5 Note on EMC (electromagnetic compatibility)
This product is intended to operate on a supply network with a system impedance Z
max
at the transfer point
max max
(building connection) of 0.292 Ohm max. The user has to ensure that the product is only operated on an
electrical supply network which meets these requirements. If necessary, details of the system impedance
can be obtained from the local electricity supply authority.
Note:
Any work involving opening up the oven must only be carried out by a suitably qualified Any work involving opening up the oven must only be carried out by a suitably qualified
electrician!
3.6 External connection
Equipment connected to the external connections must have interfaces which meet the requirements for
safe low voltage (e.g. PC, printer).
3.7 Water connection
The water container supplied has to be filled with distilled water and connected to the H2O connection
using the hose supplied.
For steam generation, use only:
•
Steam-distilled water (aqua dest)
or
•
Demineralised water (aqua dem) in accordance with VDE 0510/DIN EN 50272; regulations must be
strictly adhered to (production conductivity ≤ 10 µS/cm). Battery water in accordance with VDE 0510 is
available in larger chemist‘s shops, super markets, hardware stores and in the wholesale trade. The standard
VDE 0510/DIN EN 50272 has to be explicitly specified on the label. Otherwise, possible calcification in the
steam generators, steam piping and peristaltic pumps could affect the operability of the device.
Use only water with a pH value of > 5 and < 7.
