Safety Precautions for Exhaust Fan
(Model M438 Only)
In addition to starting by touching the fan switch, the exhaust fan
may start automatically if excessive temperatures occur around the
microwave oven. This may occur with high temperature frying or long
term cooking on the cooktop surface below the hood or during broiling
or the pyrolytic (self) cleaning of a range.
This automatic exhaust fan feature is designed to prevent damage from
overheating of the oven parts. The exhaust fan may stay on as long
as 30 minutes to cool the oven. The cooling time will depend on removal
of the heat source. Pushing the fan switch will not turn the fan off.
Because of the automatic exhaust fan feature, the following cautions
must be observed:
1. DO NOT leave the area when using your cooktop at a high
setting. Accidental fires from boilover or spattering on the
surface unit could spread, especially if the exhaust fan is
operating.
2. DO NOT allow grease and soil to build up in the exhaust filter.
Exhaust fan efficiency will decrease and fire may result. Clean
frequently following the filter cleaning instructions.
3. DO NOT flame foods when operating the exhaust fan. The fan,
if operating, may spread the flame and cause personal injury
or property damage.
4. In the event of a grease fire, smother flaming pan on surface
unit by covering pan completely with well-fitting lid.
5. Use care when cleaning the vent hood filter. Corrosive cleaning
agents, such as lye-based oven cleaners, may damage the filter.
