General Safety Information

The following instructions are intended to serve as a guideline for the use of the Macurco RD-VRF Refrigerant Leak
Detector. This manual will refer to this device as RD-VRF unless content is specific to a model. This manual is not to
be considered all-inclusive, nor is it intended to replace the policy and procedures for your facility. If you have any
doubts about the applicability of the equipment to your situation, consult an industrial hygienist or call Technical
Support at 1-844-325-3050.

1.1 General Description

The Macurco RD-VRF Refrigerant Gas Detector is designed to provide continuous refrigerant monitoring in VRF
(Variable Refrigerant Flow) applications. A leak in refrigerant gas could develop an oxygen depleting environment
that may lead to asphyxiation. The RD-VRF Refrigerant Gas Detector comes standard with 2 alarm levels providing
advanced warning via low detection alarming and notification to activate two onboard relays that can be used to
control valves to isolate or shutdown refrigerant supply lines, engage exhaust fans, provide notification alarms, and
communicate to a Building Management System.

1.2 List of warnings and Cautions

Each person using this equipment must read and understand the information in this
user manual before use. Use of this equipment by untrained or unqualified persons or
use that is not in accordance with this user manual may adversely affect product
performance.
Use only for monitoring the gas which the sensor and monitor is designed to detect.
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 manual, or contact Technical
Support at 1-844-325-3050.
This equipment may not function effectively below 14°F or above 122°F (-10°C or
above 50°C). Using the detector outside of this temperature range may adversely
affect product performance.
This detector helps monitor 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 manual, or
contact Technical Support at 1-844-325-3050.
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 electrical shock.
Do not disassemble the 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.
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. For proper use, see supervisor or User manual, or
