• Be careful of chiller installation.
- Keep enough clearance around the product for service and especially for air cooling type, install the product at well
ventilated location where there is no obstacle.
• Harsh chemical, household bleach or acid cleaner should not used to clean outdoor or indoor coils of any kind.
- These cleaners can be very difficult to rinse out of the coil and can accelerate corrosion at the fin/tube interface
where dissimilar materials are in contact. Use environment friendly cleaner.
• Be careful when restarting the product.
- When a safety device is triggered, remove the cause and then restart the product. Repeating the operation arbi-
trarily can cause fire and defect.
• Use appropriate tools.
- Use tools appropriate for the repair work and calibrate the measuring devices accurately before using. Using inap-
propriate tools can cause an accident.
• Be careful of sound and odor.
- If you hear a weird sound or smell an odor, immediately stop operating the system and contact the service center.
It may cause fire, explosion or injury.
• Be careful of injury.
- Check the safety label of the safety device. Follow the above precautions and the contents in the label. It may
cause fire and injury. To prevent the formation of the condensed water, the pipe connected to the evaporator as
well as the evaporator itself should be well insulated.
• Check.
- Perform periodic checks. If any problem occurs, stop the operation and contact the service center. Insufficient
check may cause fire, explosion or error.
• Do not attempt to bypass or alter any of the factory wiring.
- Any compressor operation in the reverse direction will result in a compressor failure that will require compressor
replacement.
• Do not use jumpers or other tools to short out components, or bypass the parts differently from recommended pro-
cedures.
- Short-circuiting the control board ground line with other wires can damage the electric module or electric compo-
nents.
• Water must be within design flow limits, and should be treated cleanly.
- This make it possible to ensure proper machine performance and reduce the potential of tubing damage due to
corrosion, scaling, erosion and algae. LG Electronics is not responsible for any damage caused by cooling water
not treated or improperly treated.
• Consult a water treatment specialist for proper treatment procedures.
- Hard scale may require chemical treatment for its prevention or remove.
• Do not overcharge refrigerant to the system.
- Refrigerant overcharging results in higher discharge pressure with higher cooling fluid consumption. Also it can
damage the compressor and increase the power consumption. Also it can damage the compressor and increase
the power consumption.
• Do not add different type of oil.
- It may cause abnormal operation of chiller.
• Turn controller power off before service work.
- It secures safety and prevents damage to the controller.
• Maintain the compressor oil pressure to normal level.
- Use proper safety precautions whem relieving pressure.
• Welding the evaporator head or nozzle part is not recommended.
- If the part requires welding, remove the chilled water flow switch and entering/leaving fluid thermistors before
welding.
- After the welding is completed, reinstall the flow switch and thermistors.
- Failure to remove these devices may cause component damage.
• Do not open the circuit breaker arbitrarily during the operation.
- It may cause damage or malfunction.
