  • Page 29: Installation, System Processing And Commissioning

    11. Installation, System Processing and Commissioning Utmost care must be taken while handling the Large ZX condensing unit. Please go through the contents below to ensure proper handling. a. Location and Fixing Large ZX should always be installed in a location that ensures clean air flow. The minimum operat- ing space for unit is described in below figure.
  • Page 30 b. Refrigeration Piping Installation All interconnecting pipes should be of refrigeration grade, clean, dehydrated and must remain capped at both ends until installation. Even during installation, if the system is left for any reason- able period (say two hours), pipes should be re- capped to prevent moisture and contaminants from entering the system.
  • Page 31 b. Brazing Recommendation Maintain a flow of oxygen-free nitrogen through the system at a very low pressure during brazing. Nitrogen displaces the air and prevents the formation of copper oxides in the system. If copper oxidization is allowed to form, the copper oxide material can later be swept through the system and block screens such as those protecting capillary tubes, thermal expansion valves, and accumu- lator oil return holes.
  • Page 32 g. Start-up & Operation Initial pressure test (by vacuum and nitrogen) Step-by-step • Use a 4-port gauge manifold with 3/8” hose and connections to the vacuum pump. The vacuum gauge does not have to be connected for this part of the process. •...
  • Page 33 Additional Oil Charing in the System Emerson Large ZX units are supplied with oil charge in the compressor as well as the oil separator / reservoir. However, depends on the length of interconnecting piping and the refrigerant charge in the system, there might be additional oil requirement.
