AF-R100CX AF-R120CX TO CHANGE TEMPERATURE SETTING Procedure During cooling operation Pad Display / Indicator TEMP F Touch the TEMPERATURE setting pad to adjust the temperature setting. • It can be set within the range of 64°F to 86°F. hr ---Lower temp. ---Raise temp. • Display will change as you touch the pad. The latest temperature setting will be memorized and will appear on the display the next time the unit is turned on.
AF-R100CX AF-R120CX ENERGY SAVER During normal operation, the thermostat automatically controls cooling and the fan runs continuously. When the ENERGY SAVER is selected, the thermostat automatically controls cooling and the fan automatically stops when the compressor is not operating. (Fan will stop 30 seconds after the compressor stops.) Procedure Pad Display / Indicator During cooling operation 1. Touch ENERGY SAVER pad. 2. To cancel, touch ENERGY SAVER pad again.

AF-R100CX AF-R120CX 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-R100CX AF-R120CX HEATING THE TUBING Direct the torch flame so that the larger tube receives most of the heat. Silver solder flows at 1200˚F and silfos flows at 1300˚F. Heat all around the tubing. The flame is composed of two cones, a smaller inner cone (pale blue) in color and a much larger outer cone. The hottest part of the flame is at the tip of the inner cone. The flame should be directed at the joint with the tip of the cone just touching the surface of the tubing. Figure 3 and 4.
AF-R100CX AF-R120CX A very faint green indicates a small leak. The flame will be unmistakably changed to green or purple when large leaks are encountered. To simplify leak detection pressurize the system to approximately 75 lbs. Some leaks can be located by a visual inspection of the system components and solder joints and if oil is found at any given location it generally is a sign that a leak exists at that point due to the fact that flame does carry oil with it travels through the system.
AF-R100CX AF-R120CX MICROCOMPUTER CONTROL SYSTEM 1. Temperature control characteristic 1-1 COOL operation In the “COOL” mode, the thermostat circuit is controlled by two thermostat lines (C1, C2). 3. Fan speed Fan speeds are given by the fan motor, “H”, “M” and “L”, which are available in the following operation mode. Room temperature (°F) Table Y-1 86 C1 84 C2 Fan motor H M L M 4. 12-hours timer 64 62 64 Preset temperature (°F) ("THERMO" switch) 86 Figure Y-1 2.
AF-R100CX AF-R120CX 6. Safety start When you turn the air conditioner OFF and restart again soon, wait at least 3 minutes before the cooling operation starts. 7. Test mode Keep pushing both buttons “POWER ON/OFF” and “ " ” and supply the power, the system will go to the test mode. In this mode, the output operation is switched by pushing buttons. Normal outputs are shown in Table Y-2. Table Y-2 No.
