Subcooling Charging in Cooling between 55° F and 120° OD Ambient Trane has always recommended installing Trane 4. Measure Liquid Line Temperature and Refrigerant approved matched indoor and outdoor systems. Pressure at service valves. 5. Determine total refrigerant line length, and height The benefits of installing approved indoor and outdoor (lift) if indoor section is above the condenser.
System Charge Adjustment Table 24. Temperature Measurements (Systems can be rated with TXV, EEV or Piston. Ensure charging method is correct). Check the outdoor temperatures. 120° F Subcooling using “Charging Mode-Cooling” is the only recommended method of charging between 55 ° F and 120° F ambient outdoor temperature.
Charging the Unit Table 26. Stabilize the system Wait 20 minutes for the system condition to stabilize between adjustments. Note: When the Liquid Line Temperature and Gage Pressure 20 MIN. approximately match the chart, the system is properly charged. Remove gauges. Replace service port caps to prevent leaks.
