2 Basic safety instructions
With the EC Declaration of Conformity and the CE mark, we affirm that this prod-
uct complies with the basic health and safety requirements in accordance with
Directive 93/42/EEC Annex II (see Chap. 16 "Declaration of conformity").
Hazards may still arise from the product if it is used incorrectly by inadequately
trained personnel or not as intended.
2.1 Intended use
This product is exclusively approved for the applications stated in the instruc-
tions. Namely for central sterilization, substerilization in the OR area, in hospitals,
clinics, laboratories and specialist medical practices. All other applications are
considered to be non-intended use.
2.2 Exercise duty of care
• Only use original racks, spare parts and accessories
•Load the rack as intended (see Chap. 7 "Machine description")
•Daily maintenance work on the machine must be carried out regularly and
in accordance with regulations (see Chap. 14 "Maintenance")
•Validate the program parameters regularly (see Chap. 2.6 "Safety through
process validation")
•Installation, deinstallation, maintenance or modification must only be
performed by persons authorized by Belimed
2.3 Operation only by authorized personnel
This product must only be used, maintained and repaired by authorized, trained
and briefed personnel. This assumes that these instructions are read and under-
stood. Responsibilities and competencies in connection with operation, servicing
and maintenance must be clearly defined and observed.
2.4 Safety instructions on the machine
Warning"Dangerous voltage"
Warning "Hot surface"
Warning"Caustic substances"
Follow safety instructions of the dosage media manufacturer!

Basic safety instructions
2.5 Observe fields of application
Cleaning and disinfection of:
• surgical instruments
• minimally invasive instruments
• instruments for anesthesia and intensive care
• baby bottles and teats
• OR shoes
• laboratory equipment used in research and production
• rigid endoscopes
• eye instruments
• neurosurgical equipment
WARNING!
Disposable products must not be reprocessed! Always observe the in-
structions of the medical device manufacturer!
2.6 Safety through process validation
The objective of process validation is to create a high level of safety in the repro-
cessing of medical devices in order to afford operators and patients the highest
possible level of protection. Process validation consists of:
a) Type test / factory test
b) Process validation, comprising:
• IQ (Installation Qualification)
• OQ (Operational Qualification)
• PQ (Performance Qualification)
c) Routine testing / annual requalification
CAUTION!
Validation must only be carried out by authorized persons! Machines must
only be operated with processes validated in accordance with regulations!
Only use components (items to be washed, racks, programs and dosage
media) which have been validated together.
The safety of operators and patients may be compromised if the machines used
are not validated in accordance with regulations.
NOTICE
Further information about process validation may be obtained from Belimed
Customer Service.
