Installation
9
Do not install in turbulent air from ceiling fans. Do not
install near doors and windows that open to the outside,
near fresh air vents, or anywhere that is drafty. Rapid air
circulation from fans or fresh air from outside may cause
the sensors to display an inaccurate reading in the
presence of CO.
Do not install this alarm in a switch or dimmer-controlled
outlet.
Do not install in areas where the temperature is colder
than 4.4˚C (40˚F) or hotter than 37.8˚C (100˚F). These areas
include unconditioned crawl spaces, attics, porches and
garages. Extreme temperatures will affect the sensitivity of
the alarm.
Do not install this unit near deep cell large batteries. Large
batteries have emissions that can cause the alarm to perform
at less than optimum performance.
The following conditions can result in transient CO
situations. Excessive spillage or reverse venting of fuel-
burning appliances caused by outdoor ambient conditions
such as:
1) Wind direction and/or velocity, including high gusts
of wind, heavy air in the vent pipes (cold/humid air
with extended periods between cycles).
2) Negative pressure resulting from the use of exhaust
fans.
3) Simultaneous operation of several fuel-burning
appliances competing for limited internal air.
4) Vent pipe connections vibrating loose from clothes
dryers, furnaces, or water heaters.
5) Obstructions in, or unconventional, vent pipe
designs which can amplify the above situations.
6) Extended operation of unvented fuel-burning
devices (range, oven, fireplace, etc.).
7) Temperature inversions which can trap exhaust
gasses near the ground.
8) Car idling in an open or closed attached garage, or
near a home.
