6. REFRIGERANT PIPING WORK
<For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit.>
<Execute thermal insulation work completely on both sides of the gas piping and the liquid
piping. Otherwise, a water leakage can result.>
Be sure to use insulation designed for use with HVAC systems.
<Also, in cases where the temperature and humidity of the refrigerant piping sections might

may form on the surface of the insulating material.>
<Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not
possible if the types of refrigerant are not the same.>
