INSTALLATION AND OPERATING INSTRUCTIONS
The following instructions are intended to serve as a guideline for the use of the Macurco CM-6 Carbon
Monoxide Detector. It is not to be considered all-inclusive, nor is it intended to replace the policy and
procedures for each facility. If you have any doubts about the applicability of the equipment to your situation,
consult an industrial hygienist or call Technical Service at 1-877-367-7891.
This detector helps monitor for the presence and concentration level of a certain specified airborne gas. Misuse may produce an
inaccurate reading, which means that higher levels of the gas being monitored may be present and could result in overexposure and
cause sickness or death. For proper use, see supervisor or User Instructions, or call Technical Service at 1-877-367-7891.
Location
A CM-6 is normally mounted at breathing level, about 5 feet (1.5 meters) above the floor on a wall or column in
a central area where air movement is generally good. The unit, on average, can cover about 5,000 sq. ft. (465
sq. meters). The coverage depends on air movement within the room or facility. Extra detectors may be needed
near any areas where people work or where the air is stagnant. Do NOT mount the CM-6 where the normal
ambient temperature is below below 0°F or exceeds 125°F (below -18
C or above 52C).
High voltage relay terminals (120/240 VAC) are located within this detector, presenting a hazard to service technicians. Only qualified
technicians should open the detector case and service the internal circuits. Ensure power is removed from the detector relays prior to
servicing the unit. Failure to do so may result in sickness or death.
