•
Install an external isolator switch (if it is not provided) to prevent electrical shock.
RECOMMENDED FUSE AND CABLE SIZES
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 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.
