• Do not allow water to remain in the water pipes if the unit is not operating for a long period.
Water must be drained out if the unit is not running during winter. Failing to do so would cause the pipe to crack.
• Do not drink the chilled water in the unit.
• Refer to the wiring diagram provided on the unit when making electrical wiring. See page iii / iv.

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. Do not ground any electrical
equipment to the water piping.
• 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.
• Neutral wire size must be 3 times larger than the incoming live wire size.
