• Be careful to avoid injury.
- Check the safety label of the safety devices.
Observe the precautions shown above and the contents of the label. It may cause a fire and injury.
To prevent the formation of condensate, insulate not only the evaporator but also the piping connected to the
evaporator.
• Check
- Carry out periodic checks. Stop operation and call the service center when a problem is detected.
Insufficient inspection may cause a fire, explosion, and product failure.
• Do not remove or change the wire connection initially connected when the Chiller was delivered.
- The compressor operating in the opposite direction may cause a failure, and it needs replacement.
• Do not short-circuit the parts by using a jumper or other tools, or bypass unlike the normal procedures.
- Ground of the control board and short-circuit of the other wirings may cause damage to the electrical module or
parts.
• Flow should remain within the designed range, and it should be handled cleanly.
- It guarantees the performance of the product and reduces a possibility of tube damage due to corrosion, precipi-
tate, moss, etc.
LG does not take responsibility for damage of the Chiller caused by unhandled or inadequately handled cold water.
• Consult with a specialist about proper cold water treatment.
- Chemical treatment may be needed to prevent or remove precipitate, corrosion, etc.
• Do not overcharge the system.
- Overcharge increases the discharge pressure of the compressor and consumption of the refrigerant.
Also it can damage the compressor and increase the power consumption.
• Disconnect the controller power before service.
- It secures the safety and prevents damage to the controller.
• Welding the evaporator head or nozzle parts is not recommended.
- If needed, remove the flow switch and the thermometers in the inlet and outlet of the cold water before welding.
Reinstall the flow switch and thermometers after welding.
If the flow switch and thermometers are not removed, it may cause damage to the parts.
