79 S4359146 10. HOW TO PROCESS TUBING The narrow tubing side is connected by flare nut, and the wide tubing side is connected by brazing. 10-1. Use of the Flaring Method Many of the conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units.
80 S4359146 10-4. Precautions during Brazing ● Replace air inside the tube with nitrogen gas to prevent copper oxide film from forming during the brazing process. ● Do not allow the tubing to get too hot during the brazing process. The nitrogen gas inside the tubing may overheat, causing refrigerant system valves to become damaged.
81 S4359146 10-7. Taping the Tubes (1) At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped with armoring tape in 1 bundle. To prevent the con- densation from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing.
5 5 5 5 5 C 82 S4359146 11. AIR PURGING Air and moisture in the refrigerant system may have undesirable effects as indicated below. ● pressure in the system rises ● operating current rises ● coo.
5 5 5 5 5 C 83 S4359146 CAUTION To avoid nitrogen entering the refrigerant system in a liquid state, do not use the nitrogen cylinder up side down. Use the cylinder in a vertical standing position. (Refer to the previous page.) (4) Do a leak test of all joints of the tubing (both indoor and outdoor) and both wide and narrow service valves.
5 5 5 5 5 C 84 S4359146 Charging additional refrigerant ● Charge additional refrigerant (calculated from the narrow tube length as shown in Sec. 1-5) using the wide tube service valve with the system in cooling operating mode. (Fig. 11-5) ● Use a balance to measure the refrigerant accu- rately.
85 S4359146 12. TEST RUN 12-1. Preparing for Test Run ● Before attempting to start the air conditioner, check the following: (1) All loose matter is removed from the cabinet especially steel filings, bits of wire, and clips. (2) The control wiring is correctly connected and all electrical connections are tight.
86 S4359146 12-2. PCB Setting ● Setting of outdoor control PCB (A) Standard control (single outdoor unit) In case of single outdoor unit installation, even if in case of twin, triple or quartet type (2, 3 or 4 indoor units), no setting necessary. Keep factory shipment state (R.
