d. Working Hours
1. Total of working hours elapsed since initial commissioning of the humidifier.
e. Time Remaining to minor/major service
1. Time remaining (in hours) before the next minor/major service.

Time to maintenance can be adjusted to suit water conditions.

The stated times are based on 100% steam capacity. If the operation is at a lower
capacity, the time should be extended accordingly. For example, average capacity of
50% would double the time to maintenance. Average capacity of 33% would triple the
time to maintenance. The servicing intervals are set up using the rotary switch “S2” on
the control board.
