Cleaning the Unit
The MPS12 does not use any internal filters. Air is drawn through the fan grille on the side of the chassis, blown
through a heatsink tunnel and out through ventilation slots in the other side of the chassis. It is not necessary to
open the unit for cleaning. Simply keep the fan and ventilation slots free of dust and dirt using a vacuum cleaner
and dry, lint free cloth. Do not use liquid cleaners or compressed air to clean the unit.
Always switch the unit off before inspecting or cleaning it.
Replacing the mains fuse
The AC mains fuse is located on the rear of the MPS12 unit next to the AC mains connector. In the event of a
mains surge or under-rated fuse value, the fuse will rupture. Switch off the power supply and remove the mains
lead plug from the "AC MAINS IN~" socket on the rear of the unit. Check the fuse and replace if necessary. In
the event of repeated failure of the mains fuse, consult your Allen & Heath service agent.
In the unlikely event of an internal DC rail fuse failure, consult your Allen & Heath service agent or Allen & Heath
technical support.
TO AVOID THE RISK OF FIRE REPLACE FUSE WITH THE CORRECT TYPE ONLY, AS INDICATED
ON THE UNIT.
