THE INDOOR UNIT INSTALLATION ENGLISH Flaring work 11 Flare nut Copper tube Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure. 1 Cut the pipes - Use the accessory piping kit or the pipes purchased locally. - Measure the distance between the indoor and the outdoor unit. - Cut the pipes a little longer than measured distance. - Cut the cable 1.5m(4.9ft) longer than the pipe length.
THE INDOOR UNIT INSTALLATION ENGLISH Connection of piping - Indoor, Outdoor, BD Unit Align the center of the piping and sufficiently tighten the flare nut by hand. Refrigerant Connections Pipe size Capacity (kBtu/h) Liquid Gas 24 1/4 (Ø6.35) 1/2 (Ø12.7) 36 3/8 (Ø9.52) 5/8 (Ø15.
THE INDOOR UNIT INSTALLATION 13 Pipe must be able to obtain the specified thickness and should be used with low impurities. Also when handling storage, pipe must be careful to prevent a fracture, deformity and wound. Should not be mixed with contaminations such as dust, moisture.
THE INDOOR UNIT INSTALLATION Welding, as when heating without nitrogen substitution a large amount of the oxide film is formed on the internal piping. The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of oil pump in compressor. It prevents normal operation of the compressor. In order to avoid this problem, Welding should be done after replacing air by nitrogen gas. When welding plumbing pipe, the work is required.
THE INDOOR UNIT INSTALLATION 15 Upward routing not allowed Pipe clamp Indoor unit Maintenance drain port 1 Remove the Air Filter. - Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. - During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. - The outside diameter of the drain connection on the indoor unit is 32 mm(1-1/4 inch).
