USE INSTRUCTIONS AND LIMITATIONS

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.

The RD-12 provides refrigerant gas detection and automatic exhaust fan control for industrial refrigeration, cold storage, warehouses or

other commercial applications. The RD-12 is capable of detecting several refrigerants including R-22, R-134A, R-404A, R-407C and R-

410A. 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-12 can be used stand alone, with the Macurco DVP-120 Detection and Ventilation

Control Panel, other fire/security panels or building automation systems.

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.

The RD-12 is not intended for use in hazardous locations. Do not mount the RD-12 where the normal ambient temperature is below 0°F

or exceeds 125°F (below -18C or above 52C). The RD-12 mounts on a 4x4 electrical box supplied by the contractor. Do not install

the RD-12 inside another box unless it has good air flow through it.

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.

The RD-12 is a line voltage, dual relay refrigerant gas detector and automatic ventilation controller. The RD-12 uses a microcomputer

controlled, electronic system to measure the concentration of refrigerant gas, actuate relays and provide a 4-20mA output. The RD-12

has a long life solid-state sensor (expected life of 7+ years). The RD-12 is a low level meter capable of displaying from 0-1,000ppm of

refrigerant gas.
