IMPORTANT : * The figures shown in the table are for information purpose only. They should be checked and selected to comply with
the local/national codes of regulations. This is also subjected to the type of installation and conductors used.
** The appropriate voltage range should be checked with label data on the unit.
• All field wiring must be installed in accordance with the national wiring regulation.
• All the terminals and connections must be tightened. Improper connection and fastenings could cause electric shock, short
circuit and fire.
• Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing wiring work according to
the wiring diagram.
• The unit must be GROUNDED to prevent possible hazards due to insulation failure.
• All electrical wiring must not touch the refrigerant piping, compressor, pump, fan motor or any moving parts of the fan
motors.
• Do not operate the chiller with wet hands. It would result in electric shock.
• Do not use fuse of different amperage than stated. Using wire etc. to replace a fuse could cause equipment damage or fire.
