CAUTION
• 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.
ELECTRICAL AND WIRING
• Refer to the wiring diagram provided on the unit when making electrical wiring.
• Do not ground any electrical equipment to the water piping.
• Install an external isolator switch (if it is not provided) to prevent electrical shock.

CAUTION
• 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.
• Don't use joined and twisted wires for incoming power supply.
* Reading taken at rated compressor frequency. The power input and current differ depending on the combination of outdoor
temperature and entering water temperature. For further detail, please refer to technical manual.
