1. CAUTIONS FOR SAFETY _ WARNING/CAUTION
• Be sure the installation area does not deteriorate with age
- If the base collapses, the chiller could fall with it, causing property damage, product failure, or personal injury.
• Be sure to dispose the packing materials safely.
- Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries. Tear apart
and throw away plastic packing bags so that children may not play with them. If children play with a plastic bag
which was not torn apart, they face the risk of suffocation.
• Do not touch any of the refrigerant piping during and after operation.
- Pipe during and after the operation can be hot or cold depending on the condition of the refrigerant flowing
through the refrigerant pipe, compressor and refrigerant cycle parts. Touching the pipes at this time can cause
burns or frostbites.
• Turn on the main power 12 hours before starting to operate the product.
- If you operate the product immediately after turning on the main power, it can severely damage the internal parts.
Keep the main power on while operating.
• Do not immediately turn off the main power after the product stops operating.
- Wait at least 5 minutes before turning off the main power. If not, it may cause water leakage or other problems.
• Do not operate the product with the panel or safety devices removed.
- Rotating parts or high temperature/pressure parts can cause safety accidents.
• Be careful when disposing the product.
- When disposing the chiller, request to the specialized expert.
• Use a firm stool or ladder when cleaning or maintaining the chiller.
- It may cause an injury.
• Be careful of high temperature.
- Be careful not to make body contact to the parts of the chiller in high temperature. It may cause a burn.
• Be careful of high voltage.
- Install separate wiring for the power and always install and use dedicated power supply and circuit breaker. It can
cause electric shock and fire.
• 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 components.
• 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.
