MAINTENANCE
9.1 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 04010 APRILIA (LT) - ITALY, or
to a other Authorised 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 sterilisation 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 specialised technical people.
9.2 CLEANING OF THE CABINET
Switch the equipment off completely 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.
9.3 CLEANING AND STERILISATION OF THE ACCESSORY ITEMS
The best thing to do is to use only one time use accessories and discard them after use. Since some of the accessory items are
to be used more than once it is mandatory to clean carefully and sterilize those accessories before the new use. The best way to
clean and sterilize the reusable items is to follow the direction of the supplier of each item. When original reusable accessories
supplied by LED S.p.A. are applied, the cleaning by using deep cleanser and sterilization through steam sterilization at 121 °C
is recommended.
9.4 GUIDE TO THE SOLUTION OF THE PROBLEMS
In case of problems before all it is advised to check for the correct installation of the unit and for the correct connection of the
accessories. The code of the produced error is visualized on the seven segments display, while the description is on the LCD
