The only maintenance required is filter cleaning and replacement. The turbine filter must be clean at all times to provide sufficient air flow to cool motor and atomize the fluid. Check turbine pre-filter (22) daily for cleanliness. Check the main paper filter (21) weekly, minimum. NOTE: To check filter, turn on turbine and place piece of paper against pre-filter. If air intake holds paper in place, filter is okay. System 3800t and System 4900t models have an air filter indicator light on the front panel. If the filter is clogged or has low airflow the light will come on as in Fig. 7 below. WARNING To avoid damage to the turbine and possible electric shock, never install a damp filter in the turbine.
