Maintenance
To keep your device in good working order, you must follow these steps:
DO carefully remove any accumulated dust from the outer enclosure once a month.
NEVER use detergents or solvents to clean your device – this may permenantly or
temporarily damage the gas sensing elements.
NEVER spray air fresheners, hair spray, paint or other aerosols near the device.
NEVER paint the device. Paint will seal vents and interfere with the device.
