2 General notes and safety notes You have purchased a technically fully proven product which has been produced in Germany with the use of high-grade materials and the application of the latest manufacturing techniques; it has been factory tested for many hours. In addition we guarantee the supply of spare parts over 10 years.
Installation facilities (accessories) The oven can be placed on the floor or on a bench (working surface). It is important that the oven is set up accurately horizontally; the door may have to be adjusted (see Section „Maintenance“) min. 20 cm 3 8 cm 8 cm 15 cm min. min. min. The spacing from the back of the oven to the wall should be at least 15 cm. The spacing to the ceiling must not be less than 20 cm and that at the side to the wall not less than 8 cm.
3.4 Initial start-up When the oven is started up for the first time, it should be supervised continuously until steady conditions have been reached. Severe vibrations during transport may cause movement of the temperature probe in its holder inside the chamber. Note therefore that before the first start-up the temperature probe should be checked for its correct position and, if necessary, carefully aligned in its mounting (see ill). Ill: Chamber ceiling with Pt 100 metal temperature probe 3.

5 Oven construction and operation Ovens Series UNB, INB and SNB have natural ventilation. In Series UFB amd SFB ovens, air circulation is provided by a fan on the back wall of the chamber. 4 chamber 6 air valve 7 air discharge 3 ventilation slots 5 fan 1 air supply fresh air 2 preheat chamber The incoming air (1) is warmed in a preheat chamber (2) in both convection and fan-circulation ovens. The preheated air enters the chamber (4) through ventilation slots (3) in the chamber side wall.

Oven switched off.
6 Selecting the operating mode Timer operation Normal 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. 7 Normal operation In this operating mode the oven operates continuously and heats and controls to the set temperature.
8 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.
9 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. If the electronic monitor system should fail during operation and the fixed factory-set maximum temperature is exceeded by approx. 20°C the temperature limiter switches off the heating permanently as a final protective measure. The alarm symbol lights up as warning.
10 Sterilisers 10.1 Purpose definition for MEMMERT hot air sterilisers The oven SNB/SFB is intended for the sterilisation of medical materials by dry heat using hot air at atmospheric pressure. 10.2 Note in accordance with Medical Products Guidelines The product lifetime specified by the manufacturer is 8 years. 10.
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. Please note that these values can be employed only with correct and loose distribution of the load.
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! 10.
11 Cleaning Regular cleaning of the easy-to-clean inside of the chamber prevents deposits which over time can detract from the appearance and the functionality of the stainless steel chamber . The metal surfaces of the oven can be cleaned with commercially available cleaning agents for stainless steel. It is important to ensure that no rust-forming object comes into contact with the chamber or the stainless steel casing. Rust deposits cause infection of the stainless steel.
13 Error messages E-0 E-1 E-2 E-3 Error on self test Power module triac faulty Power module faulty PT100 temperature probe faulty 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.
