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 overheating at connection points and a possible fire hazard. • To prevent possible hazards from insulation failure, the unit must be grounded. • Ventilate the room well, 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 poisonous gas. • Keep all tubing runs as short as possible. • Use the flare method for connecting tubing. • 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 specifled refrigerant (R410A) in refrigeration cycle. It causes capacity down, and risk of explosion and injury due to high tension inside the refrigerant cycle. • Refrigerant gas leakage may cause fire. • Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc. • Do not leak refrigerant while piping work for an installation or re-installation, and while repairing refrigeration parts. Handle liquid refrigerant carefully as it may cause frostbite. i
