Cleaning the Cool Air Inlet Grill
Vacuum the cool air inlet grill 3 - 4 times a year to make sure there is no build up of lint or dirt that may cause improper air flow. Always unplug the appliance from the mains power before cleaning or vacuuming.
Note
Warm air is expelled through the ventilation grill.
Adequate room ventilation should be provided to avoid the contamination of air into the room from units burning other fuels, such as open fires.
