Looking After Your Amplifier:  Maintenance 

 

These maintenance instructions are for use by qualified personnel only.   Before any routine 
maintenance,  please  ensure  that  your  amplifier  is  disconnected  from  the  mains  supply! 

 
The filter behind the air intake apertures on the front of your amplifier should be cleaned or 
replaced  periodically,  e.g.  12-24  months.  (Filters  in  amplifiers  located  in  more  'dirty' 

atmospheres may require more frequent maintenance).  
 

The  filter  should  be  'dry'  cleaned,  using  a  vacuum  cleaner  preferably.  Running  the  unit 
without  a  filter  is  not  recommended  unless  it  is  within  a  'clean  room'.  Replacement  filter 
material is available. 

 
If the fan vents on the rear of the amplifier develop a build-up of dust/debris on the finger 
guards, they can be cleaned with a dry paintbrush and a vacuum cleaner.  
 

The casework of the amplifier may be cleaned with a lightly dampened cloth – do not use any 
solvents as they will damage the paint finish and could remove printing. 
 

If you have any doubts about carrying out maintenance, please refer to a service engineer or 
contact your local dealer. 

 
 

Looking After Your Amplifier:  Warranty 

 

Your amplifier is guaranteed for a period of three (3) years from the date of purchase.  We 
hope that it gives you many more years of reliable service than this, but should anything go 

wrong,  please  contact  us  to  advise  you  about  repairs  or  any  spares  you  might  require. 
 

Please do not attempt to repair the amplifier yourself as doing so will invalidate the warranty.
