CAUTION (1) When linking outdoor units in a network (S-net link system), disconnect the terminal extended from the short plug (CN003, 2P Black, location: right bottom on the outdoor main control PCB) from all outdoor units except any one of the outdoor units. (When shipping: In shorted condition.) Otherwise the communication of S-net link system is not performed. For a system without link (no con- nection wiring between outdoor units), do not remove the short plug. (2) Do not install the inter-

Deburring 5. HOW TO PROCESS TUBING Before After The narrow tubing side is connected by a flare nut, and the wide tubing side is connected by brazing. 5-1. Connecting the Refrigerant Tubing Use of the Flaring Method Many of conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts. Fig. 5-1 Flaring Procedure with a Flare Tool (1

Do not use a spanner to tighten the valve stem Packed valve Charging port caps. Doing so may damage the valves. Depending on the installation conditions, applying excessive torque may cause the nuts to crack. Valve stem Precautions for Packed Valve Operation If the packed valve is left for a long time with the valve stem cap removed, refrigerant will leak from the valve. Therefore, do not leave the valve stem Main valve cap removed. Valve stem cap Use a torque wrench to securely tighten
