• 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 mus 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.
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.
