SECTION 9 

–

 PERIODIC MAINTENANCE

 

THE 95x CONTAINS NO INTERNAL USER SERVICABLE PARTS AND REQUIRES NO INTERNAL PERIODIC 
MAINTENANCE.  THE COVERS OF THE 95x SHOULD ONLY BE REMOVED BY Vitrek OR ITS SERVICE CENTERS 

–

 

REMOVAL OF THE COVERS MAY AFFECT WARRANTY AND CALIBRATION CERTIFICATION. 

The following procedures are recommended to be performed at monthly intervals.  These require no special tools 
or equipment and take the average user about ten minutes to perform. 

CLEANING AND INSPECTION 

CABLE INSPECTION  

Carefully inspect the power cord, any high voltage cabling and (if Opt. AC-30 is fitted) all cables to the external AC-
30 transformer, for breaks, abrasions, or cracks in the outer insulation.  Replace any cable found to be damaged. 

If a high voltage cable has become excessively dirty then the user should clean it by wiping it with a wetted cloth, 
with a cleaning agent if needed.  If a high voltage cable is wetted ensure it is fully dried before returning it to use. 

FAN FILTER CLEANING  

With power completely removed from the 95x, visually inspect the cleanliness of the fan filter.  The fan filter is 
located on the rear panel of the 95x, near the power entry socket. DO NOT REMOVE THE FOUR SCREWS 
SURROUNDING THE FILTER.   

 

To remove the filter, pull on one of the tabs on the filter cover to remove the cover and then remove the filter 
itself.  Carefully brush off or blow out any dirt which may have accumulated on the filter.  Replacement filters can 
be purchased from Vitrek if needed.  DO NOT OPERATE THE 95x WITHOUT A FAN FILTER INSTALLED.  If the filter is 
damaged, e.g., is torn, then it must be replaced.  When replacing the filter into the cover, take care to ensure the 
filter is installed flat and does not impair operation of the fan. 

DISPLAY FILTER CLEANING  

Visually inspect the cleanliness of the front panel display filter.  If it is excessively dirty then it should be carefully 
wiped with a soft, lint free cloth wetted with a weak solution of dish soap.  Commercially available pre-wetted 
wipes may also be used, however under no circumstances should alcohol-based cleaners be used on the front 
panel screen as it may damage the surface.
