Deltech Fitness 8000 instruction manual Normal

NORMAL OPERATION — The green NORMAL OPERATION indicator will light when the tempera- ture inside the evaporator (chiller ) is normal.

CHECK OPERATING CONDITIONS — The red CHECK OPERATING CONDITIONS indicator will light when the temperature inside the evaporator is too high.

SERVICE DUE — The yellow SERVICE DUE indi- cator will light under three conditions: as a reminder to perform routine maintenance after 4,500 hours of dryer service (approximately six months), when a thermocouple, or when a filter element must be changed.
