Cleaning and care
Fitting the grease filter
 Fit the grease filter so that the straight
side of the grease filter is on the side
that connects to the air duct.
Example: connector for air duct on the
left
Interior of the casing
 When removing the grease filter for
cleaning, also clean off any
accessible oil or fat build-up from the
casing. Doing so will prevent a fire
hazard.
