1-2. CAUTION
Operation & Maintenance
• Always check for gas(refrigerant) leakage after installation or repair of product.
- Low refrigerant levels may cause failure of product.
• Do not install the unit where combustible gas may leak.
- There is risk of fire or failure of product
• Keep level even when installing the product.
- Unleveled refrigerant can cause problems to the product.
• Do not use the product for special usage or location such as preserving animal/plant, precision machine, artifact,
etc.
- It may cause property damage.
• Use exclusive wire for the product. Use power cables of sufficient current carring capacity and rating.
- It may cause fire and electric shock.
• When installing the unit in a hospital, communication station, or similar place, provide sufficient protection against
noise.
- The inverter equipment, private power generator, high-frequency medical equipment, or radio communication
equipment may cause the chiller to operate erroneously, or fail to operate. On the other hand, the chiller may af-
fect such equipment by creating noise that disturbs medical treatment or image broadcasting.
• To protect the product from corrosion, do not install the product where it is exposed to sea wind(salt spray) directly.
If necessary, please install shield.
- It may cause product deformation and defects.
• Make the connections securely so that the outside force of the cable may not be applied to the terminals.
- Inadequate connection and fastening may generate heat and cause fire. If the power cable got damaged, do not
directly replace it, but call the service center for replacement first.
• Do not use the product in special environments.
- Oil, steam and sulfuric steam can deteriorate the product performance or cause damage to the parts.
• Be careful when transporting the product.
- When carrying the chiller, always consult with the specialized expert.
• When transporting the chiller, always follow the methods described in the manual.
- If not, it can cause overturn, fall etc.
• 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. Failure to do so can cause water leak or other issues.
• 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.
