Charging the Unit
Table 7. Stabilize the system
1.
Wait 20 minutes for the system condition to stabilize between
adjustments.
Note:
When the Liquid Line Temperature and Gage Pressure
approximately match the chart, the system is properly
charged.
2.
Remove gauges.
3.
Replace service port caps to prevent leaks. Tighten finger tight
plus an additional 1/4 turn.
20 MIN.
Table 8. Proper Gage Pressure
Measure the liquid line temperature and pressure at the outdoor unit’s
service valve.
Measure Liquid Line Temp =
________________________°F
Liquid Gage Pressure =
________________________ PSI
Final Subcooling Value = ________________________ °F
107 °F
Table 9. Verify Performance
4.
Refer to System Pressure Curves in the Service Facts document to
verify typical performance.
