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: 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 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: Expansion Valve Selection For Low Ambient Application
Expansion Valve Selection for Low Ambient Application For systems expected to operate in varying ambient conditions – namely summer and winter temperatures – the expansion valve (TXV or EXV) sizing should take into consideration the maximum expected saturated condensing temperature at high ambient conditions (summer) and the minimum expected saturated condensing temperature, set at -25°C, during low ambient conditions (winter). -
Page 18: Start Up And Operation
Oil charging procedure Emerson ZX condensing units are supplied only with a compressor oil charge. After commissioning, the oil level should be checked and topped up if necessary. The oil level should be approximately halfway up the sight glass (ZXL/ZXD units). Oil can be charged through the Schraeder valve on suction valve. - Page 19 Bin Files Number Range Bin Number Range Family 1 to 200 201 to 300 301 to 500 501 to 600 800 to 806 Service Part After installation and initial power on, it is critical to double check the parameters below.
