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 UFP: The product is intended for heating non-sterile cloths, sheets and blankets.

• For incubators series IFP: The product is intended for heating non-sterile cloths, sheets and blankets as well as for the heat treatment of wash and infusion solutions.

• For incubators series INP: The product is intended for the heat treatment of wash and infusion solutions.

• For sterilisers series SFP: 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!

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.

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.

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 Initial start-up

Ill: Chamber ceiling with Pt 100 metal temperature probes

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).

Ill: Chamber ceiling with Pt 100 metal temperature probes

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!

5 Oven construction and operation

Ovens Series UNP and INP have natural ventilation. In Series UFP, SFP and IFP ovens, air circulation is provided by a fan on the back wall of the chamber.

air discharge

fan

air valve

preheat chamber

air supply

fresh air

chamber

ventilation slots

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 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).

9 Weekly programmer

In this operating mode the weekly programmer is activated and the oven switches on and off automatically at the programmed times. While the weekly programmer is in the OFF phase the oven is in standby mode. Heating and fan are switched off, the controller display is dimmed and shows the clock time. The sequence of the weekly programmer is repeated every week. A maximum of 9 time blocks, each consisting of ON time and OFF time, can be programmed.

ON time Range: 00:00 to 23:59 hrs.

OFF time Range: one minute above ON time to

24:00

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.
