GENERAL SAFETY INFORMATION

Intended Use

The Macurco CD-12 is a line voltage, dual relay Carbon Dioxide (CO2) detector, controller and transducer. The CD-12 utilizes an
internal switching power supply that is capable of using line voltage between 100 and 240VAC and 50-60Hz. The CD-12 has selectable
4-20 mA output, buzzer and digital display options. It is an electronic detection system used to measure the concentration of Carbon
Dioxide and provide feedback and automatic ventilation control to help reduce CO2 concentrations in conference rooms, classrooms,
meeting halls or similar applications. The CD-12 is a low level meter capable of displaying from 0-2,000 ppm (parts per million) of
Carbon dioxide. The CD-12 is factory calibrated and 100% tested for proper operation. The CD-12 uses an automated background
calibration program to set the clean air level on a regular basis.
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 32F or above 122F (0C or above 50C). 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 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 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 verification test (bump test) only use certified calibration gas at the required
concentration level. Do not test with expired calibration gas.
 Do not cover or obstruct display or visual alarm cover.
 Ensure sensor inlets are unobstructed and is free of debris
