GENERAL SAFETY INFORMATION

Intended Use

The Macurco TX-12-AM is a line voltage, dual relay Ammonia (NH3) detector, controller and transducer. The TX-12-AM utilizes an
internal switching power supply that is capable of using line voltage between 100 and 240VAC and 50-60Hz.The TX-12-AM has
selectable 4-20 mA output, buzzer and digital display options. It is an electronic detection system used to measure the concentration of
NH3 and provide feedback and automatic exhaust fan control to help reduce NH3 concentrations in industrial refrigeration, warehouses,
hockey rinks or other commercial applications. The TX-12-AM is a low level meter capable of displaying from 0-100 ppm of Ammonia.
The TX-12-AM 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 0F or above 125F (-18C or above 52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 (100-240VAC) 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 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
 Ensure sensor inlets are unobstructed and is free of debris
