Installation And Operating Instructions - Macurco RD-12 Instructions D'utilisation

INSTALLATION AND OPERATING INSTRUCTIONS

The following instructions are intended to serve as a guideline for the use of the Macurco RD-12 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 Service at 1-877-367-7891.
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.
Location
A RD-12 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-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. 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).
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 removed from the detector relays prior to
servicing the unit. Failure to do so may result in sickness or death.
General Wiring Information
With the exception of the safety ground, all field wiring is completed via modular connectors (provided). After wiring, simply plug the
modular connectors into the matching connectors on the back side of the detector.
Mains Power Connection
Mains connections should be done in accordance with National and Local Electrical Codes. Only qualified personnel should connect
Mains power to any device. Macurco recommends a minimum wire size of AWG18 and the wire insulator must be rated for 140 °F
(60°C) service. The modular connector will accept wire from 12 to 24 AWG.
The safety ground wire should be secured to the ground screw of the metal electrical box. Tighten the screw and make sure the wire is
snug. Ensure that the wire cannot be pulled out from under the screw.
The Line (L) and Neutral (N) wires should be stripped 1/4 in. (6.5 mm), insert the wire into the "L" and "N" wire positions of the modular
Fan/Power connector and tighten the screw clamp. Ensure that the wire cannot be easily pulled from the connector. Plug the mo dular
connection into the Fan/Power connection and ensure that it latches into the header properly.
