    Installation WARNING High pressure! Injury to skin and eyes possible! Be careful when opening connections on a pressurized item. Copeland EazyCool 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, dust, plastic bag, leaves or papers from covering the condenser and its fins.

  • Page 32: Table 25: Maximum Operating Currents For Cable Selection

    Electrical connection 3.2.1 Power supply connections The electrical connection of the condensing unit to the power supply must be made by qualified technicians according to the valid electrical directives, for instance DIN EN 60204-1. Also the voltage drop and temperatures on line must be considered for cable selection. Copeland EazyCool ZX units are designed for a 380-420V / 3Ph / 50 Hz power supply for TFD and 220-240V / 1Ph / 50 Hz power supply for PFJ.

    NOTE: It is strongly advisable to insulate both the suction and liquid interconnecting piping between the ZX unit and the evaporator. 3.3.2 Brazing recommendations IMPORTANT Blockage! Compressor breakdown! Maintain a flow of oxygen-free nitrogen through the system at very low pressure during brazing. Nitrogen displaces the air and prevents the formation of copper oxides in the system.

    Starting up & operation Before commissioning, ensure that all valves on the condensing unit are fully opened. Evacuation IMPORTANT The evacuation procedure is based upon achieving an actual system vacuum standard and is NOT TIME DEPENDENT! Before commissioning the system must be evacuate by the vacuum pump. Before the installation is put into commission, it has to be evacuated with a vacuum pump.
