INSTALLATION AND OPERATION 

The following sections provide guidelines for installation; location and mounting, wiring, and 
cable selection.   
 

4.1 LOCATION AND MOUNTING 

Mount the AMC-SIR Refrigerant Gas sensor/transmitter on a solid, non-vibrating surface or 
structure in an area where the ambient concentration of gas is not directly affected by the 
presence of clean air supply, ventilation systems, or blockage by surrounding articles and 
sources of interference gas or contaminants. The AMC-SIR Refrigerant Gas sensor/transmitter 
shall be installed in an area where refrigerant from a leak is most likely to concentrate. The 
installer is required to provide the necessary mounting hardware for the unit. There is a 7/8” 
conduit hole for the installation wiring located on the bottom of the enclosure, refer to Fig. 4-1. 
 

Warning:

 

Mount enclosure with the sensor located as shown in Figure 4-1.  This will ensure 
correct orientation.

Warning:

 

Choose appropriate conduit hardware as to not interfere with internal components.
