E A CLEANING A schedule should be established for periodic inspection cleaning and removal of lint from various areas of the dryer as well as throughout the duct work system The frequency of cleaning can best be determined from experience at each location Maximum operating efficiency is dependent upon proper air circulation The accumulation of lint can restrict this airflow If the guidelines in this section are met an ADC dryer will provide many years of efficient trouble free and most importantly safe operation WARNING LINT FROM MOST FABRICS IS HIGHLY COMBUSTIBLE THE ACCUMULATION OFLINT CAN CREATE A POTENTIAL FIRE HAZARD WARNING KEEPDRYERAREA CLEAR and FREE FROM COMBUSTIBLE MATERIALS GASOLINE and OTHER FLAMMABLE VAPORS and LIQUIDS NOTE REMOVE POWER FROM THE MACHINE BEFORE PERFORMING ANY MAINTENANCE ON THE MACHINE NOTE Suggested time intervals shown are for average usage which is considered six 6 to eight 8 operational running hours per day SUGGESTED CLEANING SCHEDULE EVERY THIRD or FOURTH LOAD Clean the lint screen A clogged lint screen will cause poor dryer performance The lint screen is located in the lint drawer in the base of the dryer Pull out the lint drawer brush the lint off the lint screen and remove the lint Inspect the lint screen and replace if torn NOTE The frequency of cleaning the lint screens can best be determined from experience at each location WEEKLY Open
