AF-S50CX AF-S55CX AF-S60CX HOW TO REPAIR REFRIGERATION Before sealed system work can be preformed a refrigerant recovery EPA and LOCALLY approved certification is required, additionally, EPA and LOCALLY approved refrigerant recovery equipment is required. SEALED SYSTEM REPAIR Sealed system repairs should be properly diagnosed before entering into a repair of the system.
AF-S50CX AF-S55CX AF-S60CX PROPER FLUXING Flux is necessary when using silver solder; it is not required when using silfos on copper to copper joints. To do a good job the flux should cover the tube surface completely. Be careful not to introduce any flux inside the tubing. Fluxing should be done after the tubing is mated together and just before brazing is done. Do not allow it to dry out. When brazing, the flux should become entirely liquid and clear, like water.

AF-S50CX AF-S55CX AF-S60CX ELECTRICAL COMPONENT TEST RUNNING CAPACITOR AND FAN CAPACITOR CAUTION: DISCHARGE THE RUNNING CAPACITOR AND FAN CAPACITOR BEFORE TOUCHING CAPACITOR OR WIRING. (1) Discharge capacitor by shorting terminals. (2) Take the wires off the capacitor terminals. (3) Set the selector switch of a volt-ohm-meter (or a tester) on the resistance range. (4) Connect the probes to the capacitor terminals and watch the indicator swing. The indicator does not swing at all ..... Open.
