STEP 6 - Adjust refrigerant level to attain proper gage pressure.
Add refrigerant if the Liquid Gage Pressure is lower than the chart value.
1. Connect gages to refrigerant bottle and unit as illustrated.
2. Purge all hoses.
3. Open bottle.
4. Stop adding refrigerant when liquid line temperature and Liquid Gage Pressure matches the charging chart
Final Subcooling value.
Recover refrigerant if the Liquid Gage Pressure is higher than the chart value.
STEP 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 gages.
3. Replace service port caps to prevent leaks. Tighten finger tight plus an additional 1/6 turn.
STEP 8 - Verify typical performance.
Refer to System Pressure Curves in this document to verify typical performance.
