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.
This mark in the Operating Instructions means:
Watch out
Important Note!
This mark on the product means:
Note Operating Instructions
Warning  oven hot when operating!
Observation of the Operating Instructions is necessary for faultless
operation and for any possible claims under warranty. If these
Instructions are disregarded, all claims under warranty, guarantee and
indemnification are excluded!
The right to technical modifications is reserved.
Dimensional details are not binding.
2.1 Intended purpose when used as medical product
For ovens covered by the scope of the Directive 93/42/EWG (Directive of the Commission on the
harmonization of the legal regulations of the Member States on medical devices) the following intended
purpose applies:
For ovens series UFE/IFE:
The product is intended for heating non-sterile cloths, sheets and blankets.
For ovens series SNE/SFE:
The product is intended for the sterilisation of medical products with dry heat using hot air at atmospheric
pressure.
2.2 Transport
Always use gloves!
If the oven has to be carried, at least 2 persons are required to transport it.
Do not place the oven on a readily inflammable support surface!
It is important that the oven is set up accurately horizontally!

EXCELLENT
page 5
3 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)
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.
15 cm

min.
Model 800 is mounted on castors. The front castors pivot and can be locked. In order to ensure the stability
of the oven the front castors must always be set facing towards the front.
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 models 500 to 700 can be mounted on a subframe
3.2 Wall bracket (accessory)
Oven models 200 to 700 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. (Model 700 can only be
stacked using an intermediate frame.)
 Take off cover of bottom oven
 Place drill jig (supplied with foot locators) into the inverted cover at
the back
 Mark holes and drill 4.2 mm dia.
 Screw the foot locators to the top of the cover using the screws and
nuts supplied
 Re-fit the cover

3.4 Initital 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 probes
in their holder inside the chamber. Note therefore that before the first start-up the temperature probes
should be checked for their correct position and, if necessary, carefully aligned in their mounting (see ill).
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!

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).
The oven load has to be checked carefully for its chemical compatibility with the above materials.
A compatibility table covering all these materials can be requested from MEMMERT.

 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)
This product is intended to operate on a supply network with a system impedance Zmax at the
transfer point (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
electrician!
4.4 External connection
Equipment connected to the external connections must have interfaces which meet the requirements for
safe low voltage (e.g. PC).

5 Oven construction and operation
Ovens Series UNE, INE and SNE have natural ventilation.
In Series UFE, SFE and IFE ovens, air circulation is provided by a fan on the back wall of the 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 larger air through put 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).

Further clockwise rotation selects the parameters (temperature setpoint etc.) as in operating mode I.
If no further settings (temperature setpoint etc.) are made for the ON phase, the controller accepts the
values from operating mode I.
For safety reasons, always check that an ON time has been programmed only during the required time
blocks and days.
Direct setting of the temperature setpoint:
When the controller is in stand-by mode or if the weekly programmer is in the ON phase, the temperature
setpoint can be selected directly by briefly pressing the SET key. Clockwise rotation then selects fan speed,
air flap and temperature monitor. Anticlockwise rotation again selects setting the individual time blocks.
