3 Installation and Operating Instructions

The following instructions are intended to serve as a guideline for the use of the Macurco RD-xx Refrigerant Detector. It is not to
be considered all-inclusive, nor is it intended to replace the policy and procedures for each facility. If you have any doubts about
the applicability of the equipment to your situation, consult an industrial hygienist or call Technical Support at 844-325-3050.
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 manual, or contact Technical Support at 1-844-
325-3050.

3.1 Location

A RD-xx is normally mounted low in the room on a wall or column one foot above the floor in a central area where air
movement is generally good. Use the same spacing as for smoke detectors, 30-foot centers, 900 square feet per detector (84 sq.
meters). The coverage depends on air movement within the room or facility. Extra detectors may be needed near any areas
where people work or where the air is stagnant. The RD-xx mounts on a 4x4 electrical box supplied by the contractor. Do not
install the RD-XX inside another box unless it has good air flow through it. Do NOT mount the RD-xx where the normal ambient
temperature is below 0°F or exceeds 125°F (below -18°C or above 52°C).
