The text of these Operating Instructions has been translated from the German. If any part of the text is doubtful or the interpretation is unclear, and also in case of errors, the German original is to be considered as valid. 1 Congratulations on your choice of a MEMMERT Oven! Manufactured in Germany using the latest production techniques and finest materials available, you now possess a technically superior and fully developed product. Your oven has already been under extensive testing in our factory.
2 Technical data summary MEMMERT appliances are electrically heated and thermostatically controlled. Series UM/SM have natural air circulation whilst series ULM/SLM have fan assisted circulation. A PT100 DIN B, DIN 43 760 measures the temperature in the working chamber. Ambient conditions Ambient temperature 5°C - 40°C, rH max. 80%. Overvoltage Category: I I Contamination degree: 2 according to IEC 664 Setting temperature range 30°C to nominal temperature (See rating plate) Min.

2.2 Installation options (special equipment) The oven can be set up on the floor or on a table (bench), model 500 - 700 on a subframe. Ensure at least 150 mm clearance between back of oven and wall. The distance between ceiling and oven should not be less than 200 mm and the minimum wall spacing to the sides is 80 mm. Generally, a sufficient circulation of air around the oven is required. After the oven has been set up horizontally the door can be adjusted if required (see chapter - MAINTENANCE).
3 Putting into operation Attention ! Extremely strong shocks during transport can cause a displacement of the temperature sensors in the holding clips inside the working space. Take care before the first putting into operation that the temperature sensors are checked on their correct position and if necessary are slided cautiously backwards or forwards in the holding clip (see fig.).
4 Main switch module with fresh air control The main switch module contains: o main switch to select the working mode o three signal lamps g p for display py of the oven status o slide knob for fresh air control o Main switch in position 0: oven is shut down o Main switch in position I: continuous operation o Main switch in position © : Operation with timer (special equipment) Green: wed: ready for operation fault indicator fresh air Tr: —3 ""5 "6 Yellow: oven is heating Flap closed: virtually no thr
*I 5 Working controller module The controller is operated with the aid of the rotary knob. o Set temperature regulator rotary knob to desired temperature o Scale can be locked by turning screw lock. When the working temperature is reached, intermittent illumination of the yellow pilot lamp indicates operation of the thermostat. If there are big differences between set-temperature and digital display, this can be eliminated by adjusting the controller (see maintenance).
7 Safety devices The oven can be equipped with an adjustable overheat controller (TWW), class 3.1 or adjustable temperature limiter (TWB), class 2. Both work independently of the temperature control system according to DIN 12880. By different adjustments, those safety devices can have two different functions: o Protection of oven and environment and additionally o Protection of the load from excessive temperature The safety devices should be checked at regular intervals, e.g.
Should the temperature rise above the set safety temperature, the adjustable overheat controller takes over the temperature control. o the ,,alarm" lamp turns on as soon as the TWW has switched off the heating In this case please check the TWW setting as described and readjust it if necessary. Should a fault condition be present, please contact an authorised service station for Memmert equipment. 7.
8 Directives for sterilisation in MEMMERT- hot-air sterilisers. For the hot air sterilisation, many directions exist concerning the temperatures and sterilisation times to be selected as well as the packaging of the sterilisation goods. The data to be selected, depend on the nature of the goods to be sterilised and on the type of the germs to be deactivated. Please make yourself familiar with the applicable direction for your application before carrying out a sterilisation with your MEMMERT steriliser.
With large ovens and heavy loads, the use of grates (option) is recommended instead of the perforated shelfs. In particular with heavy loads, the untested usage of these provisional values is not sufficient. For a safe sterilisation, a validation of the individual sterilisation process must be done, using e.g. additional temperature sensors or germ packets. When sterilising the air flap has to be closed after the humid load has been dried.
9 Loading Ovens described in this instruction manual must not be used for drying or warming substances which generate ignitable vapours when mixed with air. The ovens described here must never be operated in areas with an explosive atmosphere. For correct operation and uniform temperature distribution it is essential to maintain free air circulation throughout the oven.
1. Remove a screw on the cover at the lower part of the back wall and swing up the cover as until the opening in the back wall is clear. 2. Turn the adjusting disk (knurled disk, approx. 60 mm behind the back wall) with a tool (e.g. screwdriver) through a small angle. (Danger! The disk is hot!) Turning to the left increases the control temperature. Turning to the right decreases the control temperature. Look at the marks above cover plate at the back side. cover plate Adjusting disk normal regulator 3.
11 Cleaning By regular cleaning of the easy to clean interior, residues are avoided which at continuous influence can impair the outfit and function of the oven. The oven can be cleaned with commercial stainless steel cleaning agents. Please note that objects liable to rust must not be placed into the interior. Rust sediments lead to contamination of the interior or external casing.
