GENERAL SAFETY INFORMATION
Intended Use
The Macurco CM-6 is a low voltage, dual relay Carbon Monoxide (CO) detector, controller and transducer. The
CM-6 has selectable 4-20 mA output, buzzer and digital display options. It is an electronic detection system
used to measure the concentration of Carbon Monoxide and provide feedback and automatic exhaust fan
control to help reduce CO concentrations in parking garages, maintenance facilities or other commercial
applications. The CM-6 is a low level meter capable of displaying from 0-200 ppm (parts per million) of Carbon
monoxide. The CM-6 is factory calibrated and 100% tested for proper operation, but can also be calibrated in
the field.
List of Warnings and Cautions within these User Instructions
Each person using this equipment must read and understand the information in these User Instructions before use.
Use of this equipment by untrained or unqualified persons, or use that is not in accordance with these User
Instructions, may adversely affect product performance and result in sickness or death.
Use only for monitoring the gas which the sensor and instrument are designed to monitor. Failure to do so may result
in exposures to gases not detectable and cause sickness or death. For proper use, see supervisor or User
Instructions, or call Technical Service at 1-877-367-7891.
This equipment may not function effectively below 0F or above 125F (-18C or above 52C). Using the detector
outside of this temperature range may adversely affect product performance and result in sickness or death.
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.
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.
Do not disassemble unit or attempt to repair or modify any component of this instrument. This instrument contains no
user serviceable parts, and substitution of components may impair product performance and result in sickness or
death.
Using a certified gas with a concentration other than the one listed for this detector when conducting a calibration or
calibration verification test (bump test) will produce inaccurate readings. This 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
The following steps must be performed when conducting a calibration or calibration verification test (bump test) to
ensure proper performance of the monitor. Failure to do so may adversely affect product performance and result in
sickness or death.
When performing a calibration or calibration verification test (bump test) only use certified calibration gas at
the required concentration level. Do not calibrate with expired calibration gas.
If the instrument cannot be calibrated, do not use until the reason can be determined and corrected.
Do not cover or obstruct display or visual alarm cover.
Ensure sensor inlets are unobstructed and is free of debris
