Maintenance and Cleaning Instructions
IMPORTANT: Excessive lint and dust build up inside the dryer can damage the motor and heating element.
Excessive build up can also increase the dryer’s air temperature and risk injury to users. With light to moderate
wash room traffic, cleaning the hand dryer once a year will keep it in good operating condition. If the washroom
traffic is high, the dryer should be cleaned every 6 months. Read complete instruction before proceeding.
