  • Page 9: Installation

    THERE IS NO GENERAL RULE for establishing the appropriate number of sensors and their location for each application. Therefore, the guidelines described below are intended as support for installers, and not as rules in their own right. Copeland accepts no liability for the installation of the gas detectors. 4.2.1 Sensor Height...
  • Page 10: Equipment Rooms

    4.2.2 Equipment Rooms In equipment rooms, the gas detectors can be installed as follows: • Position the gas detectors near areas with a high concentration of refrigerant, such as compressors, cylinders, storage tanks, pipes and conduits. Avoid vibrating surfaces. • Position the gas detectors near mechanical parts such as pressure reducers, valves, flanges, joints (brazed or mechanical) and pipes.
  • Page 11: Installation Instructions

    4.3 Installation Instructions Once the optimal position to install the sensor has been chosen, it is recommended to install the sensor (identifiable on the device by the black sensor housing) in a vertical position, with the sensitive element (black part) facing downwards. The sensor can now be mounted on the wall, as follows: 1.
