1

Safety issues When operating or maintaining the Drystar 3000, always observe the following safety guidelines: • • •

•

Have electrical or mechanical defects repaired by skilled personnel only! Do not override or disconnect the integrated safety features. Always switch off the Drystar 3000 and disconnect the power cord from the outlet before carrying out any maintenance work. Always take into account the markings provided on the inside and outside of the printer. A brief overview of these markings and their meaning is given below.

Safety warning, indicating that the Drystar 3000 User and Reference manuals should be consulted before making any connections to other equipment. The use of accessory equipment not complying with the equivalent safety requirements of this printer may lead to a reduced level of safety of the resulting system. Consideration relating to the choice of accessory equipment shall include: - Use of the accessory equipment in the patient vicinity, - Evidence that the safety certification of the accessory equipment has been performed in accordance with the appropriate IEC 601-1 and IEC 601-1-1 harmonized national standard. In addition all configurations must comply with the medical electrical systems standard IEC601-1-1. The party that makes the connections acts as system configurator and is responsible for complying with the systems standard. If required contact your Agfa Service Organization. In order to reduce the risk of electric shock, do not remove any covers. Caution hot: Keep hands clear from the decurl unit. Type B equipment: Indicates that the Drystar 3000 complies with the limits for type B equipment.

Supplementary protective earth connector: Provides a connection between the Drystar 3000 and the potential equalization busbar of the electrical system as found in medical environments. This plug should never be unplugged before the power is turned of f and the power plug has been removed. Intergrounding connector: Provides a connection between the printer and other equipment which might exhibit minor ground potential differences. These differences may degrade the quality of communication between different equipment. Never remove connections to this terminal.

Section 12 / 1


1.1

DD+DIS237.01E

Transport after installation The user has to be very cautious concerning stability, when moving the printer. When doing this, he has to take into account the condition and the structure of the subsoil, obstructions and slopes. The appliance can only be transported with all covers closed. The brakes have to be loose. The appliance may not be transported continuously from one location to the other. Ventilation openings may not be covered. The Drystar 3000 is suitable for continuous operation. The Drystar 3000 enables or aids in the diagnosis of a patient. Refer to the Drystar 3000 Reference Manual for compliance with international regulations.

1.2

Environmental regulations and waste disposal In most countries Drystar film is considered industrial waste and consequently it is not allowed to dispose of it as household waste. Please consult your local waste disposal regulations. Agfa recommends to have waste Drystar film hauled away by a licensed company for recovering the silver. After its life span, do not dispose of the Drystar 3000 without consideration of local waste disposal regulations. Please consult your local sales organization.

1.3

EMC issues USA: This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio f requency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of t his equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at its own expense. If required, contact the Agf a Service organization. Canada: This class A digital apparatus meets all requirements of the Canadian InterferenceCausing Equipment Regulations. EC: This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

1.4

Compliances This equipment complies with the Medical Devices Directive 93/42/EEC and with the standards UL2601-1 of Underwriters Laboratories and CSA 22.2 No.601.1-M90 of the Canadian Standards Association.

1.5

I/O connectors Refer to the Drystar 3000 Reference Manual for more information.

General notes The maintenance instructions are to be considered confidential. Maintenance must be carried out every 12 months or always after 15.000 prints.

•

To ensure quality and functional reliability of the system all the points listed below (minimum maintenance points) must be carried out.

•

The maintenance points have been arranged in a chronologically suitable order to make the work routines as efficient as possible.

•

The sequence of the maintenance points in the checklist (see appendix) is identical with these maintenance instructions.

•

If there is a detailed description for a certain maintenance point i n the service documentation, this will be noted in the column "details".

•

During the maintenance procedure always consider the safety instructions, see TECHNICAL DOCUMENTATION section 6 / 1.

•

Please check if it is necessary to include country specific regulations as additional maintenance points!
