6.1 Verify the unit‘s alarm sound and indicators operation by enable
the TEST/SILENCE button once a week.
6.2 Remove the unit from the wall and clean the alarm cover and
vents with a soft brush attachment once a month to remove dust
and dirt.
6.3 Never use detergents or other solvents to clean the unit.
6.4 Avoid spraying air fresheners, hair spray, or other aerosols near
the CO alarm.
6.5 Do not paint the unit. Paint will seal the vents and interfere with
the sensor‘s ability to detect CO. Never attempt to disassemble the
unit or clean inside. This action will void your warranty.
6.6 As soon as possible, place the CO alarm back in its proper location
to assure continuous protection from carbon monoxide poisoning.
6.7 When household cleaning supplies or similar contaminants are
used, the area should be ventilated.
WARNING! - The following substances can affect the sensor and
may cause false actions: methane, propane, isobutene, isopropa-
nol, ethylene, benzene, toluene, ethyl acetate, hydrogen sulfide,
sulfur dioxides, alcohol based products, paints, thinner, solvents,
adhesives, hair sprays, after shaves ,perfumes and some cleaning
agents.
WARNING! - Your CO alarm will not be operational and will not mo-
nitor for CO levels without battery.
WARNING! - This apparatus is designed to protect individuals from
the acute effects of carbon monoxide exposure. It will not fully sa-
feguard individuals with specific medical conditions. If in doubt
consult a medical practitioner.
7. Carbon monoxide (CO) and toxic effects
Carbon monoxide (CO) is a colourless, odourless, nonirritating gas
classified as a chemical asphyxiant and whose toxic action is a direct
result of the hypoxia produced by a given exposure. CO is rapidly ab-
sorbed through the lungs, diffuses across the alveolar capillary mem-
brane and is reversibly bound with haemoglobin as carboxyhaemog-
lobin (COHb), however, a minute amount is present in the plasma.
The affinity of haemoglobin for CO is over 200 times its affinity for
oxygen. This reduces the oxygen carrying capacity of the blood, and
has an effect on the dissociation of oxyhaemoglobin, which further
reduces the oxygen supply to the tissues. CO is chemically unchan-
ged in the body, and is eliminated in expired air. The elimination is
determined by the same factors that applied during absorption. The
half-life while breathing room air is 2 h -6,5 h depending on the ini-
tial COHb level. If the CO level in the inhaled air is constant, the level
of COHb in the blood will approach an equilibrium (saturation) state
after several hours. However, the rate at which the equilibrium is rea-
ched depends on many factors, e.g. lung ventilation rate (physical ac-
tivity) and alveolar capillary transfer, cardiac parameters, blood hae-
moglobin concentration, barometric pressure, oxygen and carbon
dioxide concentration in the inhaled air, but the two most important
factors in determining the COHb level are the CO concentration and
the duration of exposure.
