Page 14: Installation
Installation Copeland ZX condensing units are delivered with a holding charge of neutral gas. The condensing unit should be located in such a place to prevent any dirt, plastic bag, leaves or papers from covering the condenser and its fins. The unit must be installed without restricting the airflow. -
Page 15: Location And Fixing
Location and Fixing The unit should always be installed in a location that ensures clean air flow. It is recommended that a clearance of 300 mm from the wall (or the next unit) be maintained from the unit’s left and rear panels whereas a clearance of 500 mm must be maintained from the unit’s right, top and front panels (seen facing the front of the unit). -
Page 16: Refrigeration Piping Installation
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 reasonable period of time (say two hours), pipes should be re- capped to prevent moisture and contaminants from entering the system. - Page 17 Note: For the ZXD Units, we recommend using Alco Electronic Expansion Valves (EXV). The selection of the EXV will depend on the load profile on the ZXD Unit. Please contact your local Emerson Climate Technologies office for assistance on selection.

Page 18: Electrical Connection
Electrical Connection Power Supply The ZX condensing unit electrical connection to the power supply must be made by qualified technicians, who should refer to the electrical diagrams located inside the electric connection panel. The units are designed for below power supply at ± 10% voltage tolerance. -
Page 19: Start Up And Operation
REMINDER: Do not use the system compressor as a vacuum pump and do not operate the compressor while the system is in vacuum. Emerson Climate Technologies recommends Triple Evacuation Process (best practice) to be implemented on all our installations. Step-by-step: 1. - Page 20 Refrigerant Charging Reminder ∙ The scroll compressor design requires system charging with liquid refrigerant into the liquid line. ∙ Do not vapor charge the ZX Scroll unit. After ensuring all valves are opened and system is vacuumed properly, only then start the refrigerant charging process Step-by-step: 1.
