Clean all fan protection grills.
•
Vacuum clean the openings in the cabinet and all heat sinks mounted on printed circuit
boards to ensure a normal flow of cooling air.
•
Check that all screw connections to the primary and from the secondary of the transformer
are tightened.
•
Check that connections from the secondary of the transformer to the output terminals are
tightened. (I.e. cable and bus bars carrying heavy current).
•
Check that the water-flow switch works correct.
