Ventilate the area immediately if there is refrigerant leakage • Keep the tubing free of dirt,sand,moisture,and other during the installation. contaminants to avoid damaging the refrigerant system. Leaked refrigerant gas is hazardous.Ensure there is no refrigerant • Avoid sags in the suction line to prevent the formation of oil traps. leakage after completing the installation work. • Insulate each tube with a minimum 3/8-in.(10 mm)wall thermal pipe insulation.Inserting the tubing into the insulation before making the connections will save time and improve installation , quality. DO NOT install the connecting pipe until both the indoor and outdoor units have been installed. Insulate both the gas and liquid piping to prevent condensation. 10 Specifications subject to change without notice. 38MAR-04SI
