6.1.2 Other Requirements
At least once a year the output voltage should be verified to be within acceptable limits. The
result of the test should be recorded and filed to see any deviations.
In addition, the system requires periodic inspections and routine cleaning. It is very important
to keep the all areas and components of the system free from dust or other unwanted
objects to ensure free air circulation and safe operation of the system.
