In order to be sure that the detector is operating the Green LED should be ON.
At least once a month it is recommended to verify that the detector is functional by pressing the TEST/RESET button for a few seconds.
For an efficient functioning the detector should be cleaned up every six months. Easily and carefully vacuum the detector.
Do not touch the apparatus with the hose of the vacuum cleaner.
Use the soft brush attachment of your vacuum cleaner, and unplug the detector from the electrical outlet before vacuuming.
Hand wash using a damp cloth or paper towel. Dry with a soft cloth.
DO NOT SPRAY CLEANING AGENTS OR WAXES directly onto the front panel. This action may damage the sensors, cause an alarm or cause a detection malfunction.
Instruct children never to touch, unplug or otherwise interfere with the detector.
Never use detergents or solvents to clean the detector.
Chemicals can permanently damage or temporarily contaminate the sensors.
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.
NOTE: If you will be staining or stripping wood floors or furniture, painting, wall-papering, or using aerosols or adhesives for a do-it-yourself project or hobby, before you begin: Remove the apparatus to a remote location to prevent possible damage to or contamination of the sensors. You may wish to unplug the gas detector and store in a plastic bag during the project.
The following is a list of substances that at high levels can affect the sensors and cause an alarm: Methane, ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide, sulfur dioxide.
Also most aerosols sprays, alcohol based products, paints thinners, solvents, adhesives, air sprays, aftershaves, perfumes, auto exhaust (cold start) and some cleaning agents.
