2726To keep your Smoke/CO Alarm in good working order,please follow these simple steps:• Verify the unit's alarm and LED lights operation bypushing the test/reset button once a week.• Remove the unit from mounting bracket and vacuumthe alarm cover and vents with a soft brush attachmentonce a month to remove dust and dirt. REINSTALLIMMEDIATELY AFTER CLEANING AND THEN TESTUSING THE TEST/RESET BUTTON!• Never use detergents or other solvents to clean the unit.• Avoid spraying air fresheners, hair spray, or otheraerosols near the Smoke/CO Alarm.Do not paint the unit. Paint will seal the vents and inter-fere with the sensor’s ability to detect smoke and CO.Never attempt to disassemble the unit or clean inside. Thisaction will void your warranty.Move the Smoke/CO Alarm and place in another locationprior to performing any of the following:• Staining or stripping wood floors or furniture• Painting• Wall papering• Using adhesivesStoring the unit in a plastic bag during any of the aboveprojects will protect the sensors from damage. Do notplace near a diaper pail.WARNING: Reinstall the Smoke/CO Alarm as soon as pos-sible to assure continuous protection.When household cleaning supplies or similar contami-nates are used, the area must be well ventilated. Thefollowing substances can effect the CO sensor and maycause false readings and damage to the sensor:Methane, propane, iso-butane, iso-propanol, ethyl acetate,hydrogen sulfide, sulfide dioxides, alcohol based products,paints, thinner, solvents, adhesives, hair spray, after shave,perfume, and some cleaning agents.General CO InformationCarbon monoxide (CO) is a colorless, odorless, andtasteless poison gas that can be fatal when inhaled.CO inhibits the blood’s capacity to carry oxygen.Possible SourcesCO can be produced when burning any fossil fuel: gaso-line, propane, natural gas, oil and wood. It can be pro-duced by any fuel-burning appliance that is malfunction-ing, improperly installed, or not ventilated correctly.Possible sources include furnaces, gas ranges/stoves, gasclothes dryers, water heaters, portable fuel burning spaceheaters, fireplaces, wood-burning stoves and certainswimming pool heaters. Blocked chimneys or flues, backdrafting and changes in air pressure, corroded or discon-nected vent pipes, and a loose or cracked furnaceexchanger can also cause CO. Vehicles and other com-bustion engines running in an attached garage and usinga charcoal/gas grill or hibachi in an enclosed area are allpossible sources of CO.The following conditions can result in transient COsituations: Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient condi-tions such as: Wind direction and/or velocity, includinghigh gusts of wind, heavy air in the vent pipes(cold/humid air with extended periods between cycles),negative pressure differential resulting from the use ofexhaust fans, simultaneous operation of several fuel-burn-ing appliances competing for limited internal air, ventpipe connections vibrating loose from clothes dryers, fur-naces, or water heaters, obstructions in, or unconvention-al, vent pipe designs which can amplify the above situa-tions, extended operation of unvented fuel-burningdevices (range, oven, fireplace, etc.), temperature inver-sions which can trap exhaust gasses near the ground, caridling in an open or closed attached garage, or near ahome.Carbon Monoxide Safety InformationGeneral Maintenance
