Page 2: Installation Notices
OPERATING INSTRUCTIONS INSTALLATION Install this water cooled chiller on a solid foundation. The installation location should be convenient for operation and proper distance from the cooling tower. If the cooling tower is installed outdoors, make sure it is in an environment with good air convection, free of pollution and gas. If the cooling tower is installed at a factory, use an exhaust fan to keep good air convection. -

- Page 15 APPENDIX 1: TREATMENT FOR POOR HEAT DISSIPATION Poor heat dissipation on the condenser will result in low efficiency, current consumption increase and a poor cooling effect. When pressure reaches 285 PSI, the high-pressure protection switch for the compressor will trip. The compressor stops, and error code indication 05 or 06 will display, indication poor heat dissipation.

APPENDIX 5: PROTECTION SWITCH FAULTY When the error code indication displays ’00’, but the compressor does not run, check the following items: 1. Check PC1 on the microcomputer control panel for damaged. 2. Check the relay coil on the compressor for damage or poor contact, and check the overload protector for damage.
