Maintain more often during severe conditions. Coolant Maintenance Disconnect power before maintaining. Coolant Filter Unscrew housing to clean filter. Changing coolant: Drain coolant by tipping unit forward. Fill with clean water and run for 10 minutes. Drain and refill. All cir- Indicates an open in the thermal protection circuitry located on cuitry referred to is located inside the unit.

If these remedies do not fix the trouble with your unit, have a Factory Authorized Service Agent check unit. There are no user serviceable parts inside unit. Be sure input power cord is plugged in to energized receptacle.

Check line fuses or circuit breaker, and replace or reset if necessary. Motor overheated. Page 61 Figure Page 62 A Figure Table of Contents. Previous Page. Next Page.
