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.
•

2 Use Instructions and Limitations

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.

2.1 Use For

The RD-VRF provides refrigerant leak detection with local and remote monitoring for commercial or residential
applications. Typical applications include hotel rooms, senior care, dorms, hospitals, commercial offices, classrooms,
and other occupied spaces taking advantage of the cost-saving benefits of VRF technologies for heating and cooling.
The RD-VRF has a long-life stable NDIR (Non-Dispersive Infrared) sensor (expected lifespan of >8 years). The VRF is a
low-level meter with alarm set points at 1000ppm and 2000ppm of refrigerant gas. The RD-VRF can detect several
refrigerants including R-32, R134A, R404A, R-407C, R-410A, R-1234YF, and R-1234ZE. The RD-VRF is factory
calibrated and tested for proper operation.
Refrigerants are colorless and nearly odorless liquids or gases divided into two groups according to toxicity and
flammability. See ANSI/ASHRAE Standard 34-2007 - Designation and Safety Classification of Refrigerants for details.
Always review the refrigerant MSDS and safety classifications before use. RD-VRF can be used stand alone or
communicate to a Building Management System (BMS) via RS-485.
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.

2.2 Do NOT use for

The RD-VRF is not intended for use in hazardous locations or industrial applications such as refineries, chemical
plants, etc. Do not mount the VRF where the normal ambient temperature is below -14°F or exceeds 122°F (-10°C or
REV – 1.0
