AIR FILTER
The filter behind the air intake apertures on the front of E SERIES amplifiers should be cleaned or
replaced periodically, e.g. 3-6 months. (Filters in amplifiers located in more 'dirty' atmospheres may
require more frequent maintenance). Access is via the blue front panel retained by 2.5mm Hex screws.
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.
No other regular maintenance is required.
If you have any doubt about carrying out this procedure, refer to a service engineer or
contact your dealer.
IF YOUR AMPLIFIER DEVELOPS A FAULT, PLEASE REFER TO YOUR SUPPLIER FOR SERVICE
AND TECHNICAL SUPPORT. DO NOT ATTEMPT TO REPAIR THE FAULT YOURSELF AS THIS
WILL INVALIDATE THE WARRANTY.
