Maintenance and Cleaning
This CO alarm does not require any maintenance except occasional dust-
ing or cleaning. If necessary, occasionally vacuum the case of the CO
alarm. To clean the CO alarm, unplug each CO alarm from its wiring har-
ness and use a damp cloth to clean the OUTSIDE of CO alarm case. DO
NOT remove cover or attempt to clean inside the CO alarm. Dry the cover
completely and plug each CO alarm back onto the wire harness and
replace on the mounting bracket. Press in, hold, and release TEST/RESET
button on each CO alarm to test after cleaning.
Do not use abrasive cleansers, or spray the CO alarm with cleaning
agents or waxes, especially cleaners containing ammonia. These liquids
may impair the performance of sensors. Do not submerge the CO alarm
in water.
Troubleshooting
Problem:
The alarm is properly connected to AC power, but the green
LEDs do not light.
Solution:
Return alarm to Maple Chase for service (see warranty).
Problem:
Amber FAULT light flashes every 30 seconds.
Solution:
Press the TEST/RESET button to allow the alarm to recheck itself
internally. If the amber LED continues to flash, the alarm must be
returned to Maple Chase for service (see warranty).
Symptoms of Carbon Monoxide Poisoning
Carbon monoxide poisoning has many symptoms. Some symptoms are very
similar to the flu, the effects of intoxication, or drug usage. In many CO
cases, people feel ill and stay home to rest. This only compounds the CO
poisoning because they stay in the home where CO is present.
As CO levels rise, the symptoms become more extreme. At low levels
people will suffer headaches and mild nausea. At higher levels unconscious-
ness, heart failure, and even death can occur.
The following symptoms are related to CARBON MONOXIDE POISONING
and should be discussed with ALL members of the household:
Mild Exposure:
Slight headache, nausea, vomiting, fatigue (often described
as flu-like symptoms).
Medium Exposure:
Severe throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure:
Unconsciousness, convulsions, cardio-respiratory
failure, death.
Many cases of reported carbon monoxide poisoning indicate that while
victims are aware they are not well, they become so disoriented they are
unable to save themselves by either exiting the building or calling for
assistance. Also, young children, the elderly, and household pets may be the
first affected by CO poisoning.
The important factor with any CO poisoning, however, is time. At high levels,
CO can cause death in just minutes. At lower levels, it could take from hours
to days of constant CO exposure to have the same life-threatening effect.
The chart below illustrates the symptoms of CO poisoning by concentration
of CO and its effect over time.
Conditions That Can Cause CO Levels to Change
The following conditions can result in transient CO situations in the home.
1. Excessive spillage or reverse venting of fuel burning appliances caused
by outdoor ambient conditions, such as:
a. Wind direction and/or velocity, including high gusts of wind. Heavy air
in the vent pipes (cold/humid air with extended periods between
cycles).
b. Negative pressure differential resulting from the use of exhaust fans.
c. Simultaneous operation of several fuel burning appliances competing
for limited internal air.
d. Vent pipe connections vibrating loose from clothes dryers, furnaces,
or water heaters.
e. Obstruction in the vent pipe or unconventional vent pipe designs
which can amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace, etc.).
3. Temperature inversions which can trap exhaust gasses near the ground.
4. Car idling in an open or closed attached garage, or near a home.
