Maintenance of Motors

The motors used on the fan and the drum assembly are prelubricated for extended bearing life and require no further lubrication. However, periodic cleaning/vac- uuming of the fan/heater and around the air intake, located under the top shelf (Fig. 4), is recommended.

Make sure the power is turned OFF before proceeding.

Cleaning

Cleaning of the touchpad label at the bottom front of the unit is to be done only using a soft cloth, slightly dampened in water (if needed, a small amount of dish soap can be added to the water) and dried using a clean, dry soft cloth. Cleaning of the screen diffuser is to be done using only water and a lint free cloth. DO NOT use any abrasive household cleaners as these products will damage the touchpad controls and the diffusing screen.
