6. PREVENTIVE MAINTENANCE
6.1 GENERAL
No user adjustable parts are within the equipment, either for calibration or service purposes. The equipment housing must not
be opened: the warranty is invalidated by any unauthorized entry into the unit. In the event any repair or adjustment work
being necessary, the whole equipment should be returned to the LED S.p.A. Service Centre 04011 APRILIA (LT) - ITALY,
or to a other Authorized Centre, together with a description of the fault.
Maintenance work by the user is mainly the cleaning of the exterior of the cabinet, cleaning and sterilization of the accessory
items and checking of the equipment before each use. Carrying out function and safety check for verification of the
parameters is demanded to specialized technical people.
6.2 CLEANING OF THE CABINET
Switch the equipment off complitely and disconnect the mains supply before any cleaning is undertaken. Clean the outside
of the cabinet with a damp cloth. No chemical should be used; a mild non abrasive cleanser may be used when necessary.
6.3 CLEANING AND STERILIZATION OF THE ACCESSORY ITEMS
For what is possible it is recommended to use disposable accessories only and to eliminate them as special hospital refuse.
Nevertheless, since some accessories must be used more than once it is mandatory to clean them with care and to sterilize
them before the new use. The better way to clean and to sterilize the reusable accessories is to follow the instructions of the
supplier of every element.
Don’t clean H.F. cables, adapters or handles in an ultrasounds cleaner. Don’t sterilize H.F. cables, adapters or handles with
hot air sterilizers. After the use, clean the H.F. cables with a superficial alcoholic disinfectant. The H.F. cables or the handle
can also be dipped in a cleaning and disinfectant solution, naturally, the life of service in this case can result reduced because
of the oxidation of the contacts and cristalization of the electric thorns. Follow the instructions of the producer of the cleaning
and disinfectants products and verify that the used active elements are compatible.
Then rinse completely all the parts with distilled water.
Steam sterilize at 134 °C (272 °F) H.F. cables, handles, adpters and electrodes.
6.4 REPAIRING
H.F. cable or handles cannot be repaired.
Replace always a defective item with a new one. All the accessories for HF electrosurgery, that are compatible with the
electric characteristics of the unit and are conforming to the CE 93/42/EEC Directive, are applicable.
6.5 CHECKING OF THE EQUIPMENT BEFORE EACH USE
Each time the use of the electrosurgical equipment is planned a check of the most important safety aspects has to be
implemented considering at least the following:
Check the integrity of cords, connections, wire breakage, etc.
Assure that all the electrical equipment is properly grounded
Assure that all the accessories that should be used are available and sterilized.
6.6 FUNCTION AND SAFETY CHECKS AND TESTS
At least once a year, the following check and test should be done by the biomedical engineering department or other qualified
personnel:
Check of the connectors and mains supply cord conditions;
Visual check of the mechanical protections;
Check of the protections against the danger due to liquid's pouring, dripping, moisture, liquid's penetration, cleanliness,
sterilization and disinfection.
Check of the Equipment's Datas on the Label
Check of the availability of the Instruction's Manual
Check of the functioning of the patient plate monitoring circuit.
Check of the functioning of the H.F. output controls
Check of the uniformity of the resistance through the surface of the patient plate.
