In Case of Improper Installation The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document. SPECIAL PRECAUTIONS WARNING When Wiring ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM. • Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked. • Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death. • Ground the unit following local electrical codes. • Connect all wiring tightly. Loose wiring may cause over- heating at connection points and a possible fire hazard. • To prevent possible hazards from insulation failure, the unit must be grounded. • This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD). Otherwise, it may cause electrical shock and fire in case of equipment breakdown or insulation breakdown. When Transporting Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers. When Installing... Select an installation location which is rigid and strong enough to support or hold the unit, and select a location for easy maintenance. ...In a Room Properly insulate any tubing run inside a room to prevent "sweating" that can cause dripping and water damage to walls and floors. CAUTION Keep the fire alarm and the air outlet at least 5 feet (1.5 m) away from the unit. ...In Moist or Uneven Locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration. ...In an Area with High Winds Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle. ...In a Snowy Area (for Heat Pump-type Systems) Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents. When Connecting Refrigerant Tubing • Pay particular attention to refrigerant leakages. • Ventilate the room immediately, in the event that is refrigerant gas leaks during the installation. Be careful not to allow contact of the refrigerant gas with a flame as this will cause the generation of toxic gas. • Keep all tubing runs as short as possible. • Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection. • Check carefully for leaks before starting the test run. WARNING • When performing piping work, do not mix air except for specified refrigerant (R410A) in refrigeration cycle. It causes capacity down, and risk of explosion and injury due to high tension inside the refrigerant cycle. • If the refrigerant comes in contact with a flame, it produces a toxic gas. • Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc. i
