8 cm. Generally it is essential to have adequate air ventilation around the oven. Information on accessories will be found in our leaflet or on our internet page www.memmert.com. Please note the installation instructions for our accessories. 3.1 Subframe (accessory) Oven model 500 can be mounted on a subframe 3.2 Wall bracket (accessory)
Please note that the MEMMERT ovens described here are not explosionproof (they do not conform to the Industrial Association Specification VBG 24) and are therefore not suitable for drying, evaporating and burning-in of paints, enamels or similar materials whose solvents may produce an inflammable mixture with air.
4.2 Material quality For 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, optimum hgygienic properties and corrosion resistance against many (not all) chemicals (warning against e.g. chlorine compounds).
Controller protected by an 80 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) ...

Selecting the operating mode Normal Timer operation operation After holding down the SET key (approx. 3 sec), the current operating mode flashes on the display. A different operating mode can be selected with the push/turn control while the SET key is being held down. After the SET key has been released the controller operates in the new operating mode.
Timer operation In this operating mode the oven operates on the timer; it heats/controls to the set temperature and maintains this temperature until the set time has elapsed. The clock symbol is flashing during timer operation, then the heating is switched off; on UFB/SFB ovens the fan runs on for 30 minutes. The timer display shows END. - The time can always be set to OFF, the heating is then switched off and the timer display shows END.
Temperature monitor and protection devices 9.1 Temperature limiter (TB) All ovens of the BASIC series are equipped with a mechanical temperature limiter (TB) Protection Class 1 to DIN 12 880.

The total sterilisation time to be selected consists of the heating-up time (i.e. the time until the desired temperature has been established within the entire steriliser chamber), the actual sterilisation time, and a safety margin. The following table gives typical values for the total sterilisation time to be set, with different amounts of load, for sterilisers with and without fan.
Especially with heavy loading of the steriliser it is not sufficient to use these typical values without further tests. Reliable sterilisation requires validation of the individual sterilisation process, e.g. with the aid of additional temperature probes or by using biological or chemical indicators. Note: In sterilisation processes the vent valve on the oven must be closed after the moist sterilisation load has been dried!
Silicone grease, and to check that the hinge screws are tight. A well-closing door is essential on an oven. On Memmert ovens, tight closure of the door is ensured by a seal on the oven and another one on the door. In continuous operation the flexible sealing material may take a permanent set.
In case there is a fault on the oven, please get in touch with an authorised service organisation or contact the MEMMERT customer service department. When dealing with the service department always quote the product serial number on the oven label.
