16
Adjust refrigerant level to attain proper gage pressure.
5.
Add refrigerant if the design liquid line pressure is lower than the
chart value.
Connect gages to refrigerant bottle and unit as illustrated (Figure 40).
Purge all hoses.
Open bottle.
Stop adding refrigerant when liquid line pressure matches the
Refrigerant Charging Chart.
Recover refrigerant if the design liquid line pressure is lower than
the chart value.
Figure 41
Stabilize the system.
Wait 20 minutes for the system condition to stabilize between
adjustments.
Remove gages.
Replace service port caps to prevent leaks. Tighten finger tight plus
an additional 1/6 turn.
6.
Record system Information for reference (Table 8).
Record system pressures and temperatures after charging is
complete.
7.
When the liquid line pressure match the chart, the system is
properly charged.
20 MIN.
