After assembly a full run test is performed, with water flowing through the cooler, to verify that each refrigeration circuit operates correctly. The unit is pressure-tested, evacuated and fully charged with refrigerant and includes an initial oil charge. YDAJ units are shipped in two sections and require the installation of a two wire communication link between control panels. SPECIFICATION General YCAJ and YDAJ models are completely assembled with all interconnecting refrigerant piping and internal wiring, ready for field installation.
