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.
