15 cm 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. 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) Ovens models 200 to 500 can be wall-mounted using the wall bracket. The wall bracket is factory-fitted with a fire-resistant plate. The size and length of the screws used and of the corresponding dowel plugs depend on the total weight (oven plus load) and vary with the condition of the wall.

3.3 Stackable version (accessory) Two ovens of the same model size can be stacked on each other. Note that the oven with the lower working temperature must always be placed at the bottom. Foot locators have to be fitted on the bottom oven.

Take off cover of bottom oven

3.4 Initital start-up

Ill: Chamber ceiling with Pt 100 metal temperature probe

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 load

Full consideration must be given to the physical and chemical properties of your load (e.g. combustion temperature etc.) in order to prevent serious damage to load, oven and surroundings.

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. There must be no possibility of the formation of inflammable gas/air mixtures either within the oven chamber or in the immediate surroundings of the equipment. Large amounts of dust or corrosive fumes inside the oven chamber or in the surroundings of the equipment may produce deposits within the oven and lead to short-circuits or damage the electronics. It is therefore important that adequate precautions are taken against excessive dust or corrosive fumes.

In order to ensure proper air circulation inside the chamber, there must be sufficient spacing of the load inside the oven. Do not place any load on the floor, against the side walls or underneath the ceiling of the chamber (heating ribs). In order to ensure optimum air circulation the shelves must be so inserted that the air spacings between door, shelf and rear chamber wall are approximately equal. The maximum number and the loading of the shelves can be found in the table in the Section „Technical

Data“. With unfavourable loading (too closely spaced) and completely opened ventilation it is possible that

the set temperature may be reached only after a longer period of time.

See stick-on label “Correct Loading“ on the oven!

fan

air valve

ventilation slots

air supply

fresh air

preheat chamber

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. The fan (5) on the chamber back wall produces a large air throughput and a more intensive horizontal forced circulation compared with natural convection. The air valve (6) on the back of the oven controls the rate of air intake and discharge (air change) (7).

BASIC

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.

Fault rectification after the TB cut-out has been activated:

Switch off the oven and allow it to cool down

1. Rectify the fault (e.g. replace temperature probe) and where appropriate contact customer service

2. The oven is again ready for operation only after it has cooled down and after the fault has been

rectified.

9.2 Monitor relay

In addition to mechanical temperature protection the oven is provided with an electronic monitor relay.

If a fault occurs during operation or if the selected setpoint temperature is exceeded (by 3°C on ovens Series INB, by 10°C on ovens UNB/UFB/SNB/SFB) the monitor relay switches over the heating to this temperature in emergency mode. The alarm symbol is flashing as warning.

Fault rectification after the monitor relay may been activated: Check the controller for error messages (see Section „Error messages“) and where appropriate contact customer service.

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 Guidelines for sterilisation

For hot air sterilisation there are different regulations covering the temperature settings and the sterilisation times, as well as the packaging of the products to be sterilised. The values depend on the type and condition of the load to be sterilised and on the type of bacteria which have to be de-activated. Please make yourself familiar with the sterilisation method laid down for your application before carrying out sterilisation using your MEMMERT cabinet. The operation of the MEMMERT hot air steriliser is also subject to the Standard DIN 58 947 Part 6.

A few examples of the correct preparation for different medical products are summarised in the following table:

Load Preparation

Instruments (no soft solder) load cleaned instruments, wrapped twice in aluminium foil or in

steriliser foil suitable for hot air (recommended)

Cutting instruments load cleaned instruments, wrapped twice in aluminium foil or in

steriliser foil suitable for hot air (recommended)

Syringes (no plastics) load plunger and cylinder separately, wrapped twice in aluminium

foil or in steriliser foil suitable for hot air (recommended)

Glass and glass instruments dismantle cleaned glass vessels and all-glass syringes and place into

dishes, cool down slowly

Bottles, vessels and similar items must be sterilised without closure and with the opening downwards, in order to avoid the formation of cold air pockets. The recommended sterilisation temperature is usually 180°C (German Pharmacopoeia DAB 10)

page 15

BASIC

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. Notes on the correct loading of the steriliser can be found in these Operating Instructions and also on the label affixed to the steriliser.

The sterilisation time is increased by a factor of 4 when sterilising at a temperature of 160°C. On large sterilisers and with heavy loading it is recommended to use wire shelves (special accessory) instead of perforated shelves.

BASIC

page 16

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!

10.3 Steriliser cassettes

The cassettes should preferably be so arranged in the steriliser that the hot air flow can pass readily through the air slots.

The load to be sterilised is placed into the steriliser cassettes wrapped in aluminium foil or in steriliser foil suitable for hot air (as in the Table in the Section „Guidelines for sterilising“). The air slots in the cassette must be open during sterilisation. A temperature probe to confirm the temperature of the load can be introduced through the opening (2). After sterilisation has been completed the air slots must be closed by moving the slide knob (1).

page 17

BASIC

The sterilised and packed load can then be stored briefly in the closed cassette.

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.

If any contamination causes rust stains on the surfaces of the chamber, such spots must be cleaned off immediately and the area polished.

The control panel, the plastic input modules and other plastic components of the oven must not be cleaned using scouring cleaning agents or those contained solvents.

12. Maintenance

Important for a long life of your MEMMERT product and in case of warranty claims.

Note: Any work involving opening up the oven must only be carried out by a suitably qualified electrician!

MEMMERT products require little maintenance. It is however recommended to lubricate all moving parts of the doors (hinges and closure) once a year (or 4 times a year with continuous operation) using a thin 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. Readjustment may then be necessary in order to ensure proper closing of the door.

The top part (1) of the door hinge can, after releasing

• the 2 screws (2) at the top or bottom of the door, be moved slightly in the direction of the arrow.

The door can be adjusted after releasing the socket

• screw (3) and rotating the excentric (4) by means of a screwdriver. NOTE ! Screw (3) is locked with locking varnish. It can be released by a sharp tug using a hexagon socket key. Apply more locking varnish to screw (3) and tighten it.

The closing panel (6) can also be adjusted in the direction of the arrow after releasing the screw (5). It is important that the panel is then screwed down firmly.
