General Safety Information; Intended Use; List Of Warnings And Cautions Within These User Instructions - Macurco CD-6MC User Instructions

1 GENERAL SAFETY INFORMATION

1.1 Intended Use

The Macurco CD-6H and CD-6MC are low voltage, dual relay Carbon Dioxide (CO
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 CO
classrooms, meeting halls or similar applications. The CD-6"x" is a low-level meter capable of displaying from 0-5000 ppm (parts per
million) of Carbon dioxide. The CD-6"x" is factory calibrated and 100% tested for proper operation.
The CD-6H uses an automated background calibration program to set the clean air level on a regular basis.
The CD-6MC has the same setting and features of the CD-6H with the addition of being able to perform a manual calibration. The CD-
6MC requires a manual calibration process at a minimum of once per year using the Macurco CD6-FCK calibration kit.

1.2 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 serious injury 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 serious injury or death. For proper use, see supervisor or User Instructions,
or call Technical Support at 844-325-3050.

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 serious injury 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 serious injury or death. For proper use, see supervisor or User Instructions, or call Technical
Support at 844-325-3050.

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 de-energized from the
detector relays prior to servicing the unit. Failure to do so may result in serious injury 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 serious injury or death.

Using a certified gas with a concentration other than the one listed for this detector when conducting a 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 serious injury or death. For proper use, see supervisor or User Instructions, or
call Technical Support at 844-325-3050.

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 serious injury or death.
When performing a calibration verification test (bump test) only use certified calibration gas at the required concentration level.
o Do not test with expired calibration gas.
o Do not cover or obstruct display or visual alarm cover.
o Ensure sensor inlets are unobstructed and is free of debris
