11. Electrical connections This appliance is designed for a supply voltage of 230 V (see model identification plate). Before connecting the mains power cable it is absolutely vital to check that the required supply voltage is available, otherwise the connection could be damaged. Use the Dürr mains cable supplied. The unit may only be operated when it is closed - with sides and cover in position - and connected to the mains supply.

Before developing the first film the lifting tank of the developer and fixer baths must be filled to the overflow level, otherwise the film development quality may be impaired.
Always use cold water when making up the chemicals.
The developer unit must never be operated without its roller sets!Withouttherollersetsitispossiblethatthedeveloperandfixerfluidswillbeplacedunderpressureandwillsplashverticallyupwardsoutofthedeveloperunit�
Chemicals attack eyes and skin and there is the possibility of severe injury to the eyes.Withoutthedeveloperandfixerrollersetstherecanbenocirculationofchemicalsinthebaths�
There is the danger of mixing of chemicals.
Never operate the developer unit without fluids (chemicals, water), as this can lead to the heating controller breaking down.

Chemicals are dangerous to health or aggressive. Irritate skin and eyes. Danger of severe eye injury. Damage irreversible.
When filling chemicals always wear protective gloves and protective glasses.
If there is any contact with the eyes, immediately rinse thoroughly with water and consult a doctor as soon as possible.
Clean your hands thoroughly under running water after finishing.
Please also refer to our special safety brochure which you can find on the internet at: http://www.duerr-ndt.de or order it direct from Dürr NDT.
