Fields of application for the device Cleaning and reconditioning of: •
Surgical instruments
•
Minimally invasive instruments
•
Instruments for anaesthesia and intensive care
•
Baby bottles and teats
•
Containers
•
OT Shoes
•
Laboratory instruments used in research and production
•
Rigid endoscopes

•
Neurosurgery Warning No single-use products may be reconditioned! Always adhere to the instructions of the medical device manufacturer!
2.6
Process validation The aim of process validation is to achieve a high level of safety in the reconditioning of medical devices in order to afford the operators and patients the greatest possible protection. Process validation consists of: a) Type testing / factory testing b) Process validation consisting of: • IQ (Installation Qualification) • OQ (Operational Qualification) • PQ (Performance Qualification) c) Routine testing / Annual requalification Note Further information on process validation may be obtained from Belimed Customer Service.
Caution Validation must only be carried out by authorised persons! Devices 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 devices used are not validated in accordance with the regulations.

Warning Maximum operating pressure for steam connection 700 kPa (a)! A building excess-pressure protective device at the steam connection site with 700 kPa (a) response pressure must be provided. Use certified armatures only! Note Pressurised air connection must not be provided. Steam supply and discharge pipes are flushed via bypass. Keep electrical supply and steam supply separate. Note A line disconnector is to be installed on-site near the device and must be well within reach! The operational current is at least 60 A.
