7. Maintenance
Move the CO Alarm 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 Alarm as soon as possible to assure contin-
uous protection.
The following is a list of substances that at high levels can damage the
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, sol-
vent, adhesive, hair spray, after shave, perfume, auto exhaust (cold
start) and some cleaning agents.
When replacing the battery, use one of the following approved brands:
• Duracell
MN1604 or MX1604
• Energizer
522
• Gold Peak
GP1604A
These batteries can be purchased where you bought the alarm or at a
local hardware store. Use of a different battery may have a detrimental
effect on the alarm operation.
The 9 volt battery is not rechargeable. If the 9 volt battery is missing,
disconnected, or if the battery’s power is low, a red LED flash will occur
once every 15 seconds, accompanied by an audible beep. If this
happens, the battery must be replaced.
(For model KN-COP-DP-LS
with digital display:
“Lb” will be displayed alternately with the current
CO reading once every second).
To replace battery:
Remove the screw, if it has been used, that is holding the battery door
located on the back of the unit. Slide the battery door toward the back
oF the alarm to release it. Remove the battery and replace it with one of
the approved replacement batteries. Reinstall the back door and replace
the screw, if it has been used
IMPORTANT:
Constant exposures to high or low humidity may reduce
battery life. A good safety measure is to replace the battery at least once
a year, or at the same time as you change your clocks for daylight saving
time.
After installing or changing the battery, reinstall your alarm. Test your
alarm by using the Test/Reset button and check that the green LED is on.
Maintenance Tips
To keep your alarm in good working order, you must follow these steps:
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover once a month to remove accumulated dust.
• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.
• Avoid spraying air fresheners, hair spray, paint or other aerosols near
the alarm.
• Do not paint the unit. Paint will seal the vents and interfere with
proper sensor operation.
