4 Improper or insufficient power supply can cause undesirable operation, fire, or electrical shock. When connecting refrigerant piping, do not let any substances or gases other than the specified refrigerant enter the unit. The presence of other gases or substances will lower the unit's capacity, and can cause abnormally high pressure in the refrigeration cycle. This can also cause explosion and injury , as well as permament equipment failure. Remember : No dust, humidity or air should be allowed to enter. Do not allow children to play with or around the air conditioner.

5 Children near the unit must be supervised at all times. 1. installation must be performed by a licensed and trained technician. Defective installation can cause water leakage, electrical shock, or fire. The usage of proper tools is a requirement. 2. installation must be performed according to the installation instructions.

7 You must use an independent circuit and a dedicated breaker to supply power. Do not connect other appliances to the same circuit. Insufficient electrical capacity or defects in electrical work can cause electrical shock or fire. 7. For all electrical work, use the specified cables. Connect cables tightly, and clamp them securely to prevent external forces from damaging the terminals. Improper electrical connections can overheat and cause fire, and may also cause shock. 8. All wiring must be properly arranged to ensure that the control board cover can close properly.

8 If the control board cover is not closed properly, it can lead to corrosion and cause the connection points on the terminal to heat up, catch fire, or cause electrical shock. 9. In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed air-conditioning units is highly recommended. This is intended as a comfort cooling system. 10.
