Maintenance tips
To keep your detector in good working order:
• Perform a CO detector test once a week (see “Normal CO
detector test” on page 3).
• Vacuum the detector cover once a month to remove
accumulated dust.
• Never use detergents or solvents to clean the detector.
Chemicals can permanently damage or temporarily
contaminate the detector.
• Avoid spraying air fresheners, hair spray, paint, or other
aerosols near the detector.
• Do not paint the detector. Paint will seal the vents and
interfere with proper sensor operation.
Move the CO detector to a remote location, to prevent possible
damage or contamination of the sensor, prior to performing any
of the following:
• Staining or stripping floors or furniture, painting or wall-
papering.
• Using aerosols or adhesives.
WARNING: Reinstall the CO detector as soon as possible
to assure continuous protection.
The following is a list of substances that at high levels can
damage the CO sensor or cause temporary readings that are
not CO readings:
Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene,
ethyl acetate, hydrogen, hydrogen sulfide, and sulfur dioxide.
Also most aerosol sprays, alcohol-based products, paint,
thinner, solvent, adhesive, hair spray, after shave, perfume,
auto exhaust (cold start), and some cleaning agents.
