Periodic Maintenance
If your unit employs a filter on the air inlet for the fans, the filter should be cleaned every 30 days. If the
equipment is operated in a severe dust environment, the filters on the inlet fan may need to be cleaned
more regularly.
Turn the system off and unplug all of the AC inlet cords.
The filter can be lifted off the
fan and cleaned using an air compressor at low pressure. While the filter is out, clean the fan blades
themselves with a small brush. The fans themselves do not need lubrication.
The interior of the cabinets should be cleaned and inspected annually.
Turn the system off and unplug
all of the AC inlet cords.
Remove the top lid by unscrewing the 6-32 machine screws.
Use extreme caution when working near the AC input terminal. The power
amplifier and power supply store hazardous capacitances and voltages.
Using either compressed air or a brush with soft bristles, loosen accumulated dust and dirt and then
vacuum the interior of the cabinet. Complete a visual inspection of the interior, making sure there are
no loose connections or discolorations on any components from heat. Nothing inside the power
amplifier enclosure exceeds a temperature that is not comfortable to the touch under normal operating
conditions, so any signs of discoloration indicate potential damage.
All modular components inside the enclosure are attached to aluminium mounting plates for easy
removal and replacement. Ensure that plates are secured and the mounting hardware is tight.
