STEP 6 - Adjust refrigerant level to attain gro <br /> proper gage pressure. <br /> FPpg;, <br /> �r�r> <br /> Add refrigerant if the Liquid Gage Pressure <br /> is lower than the chart value. 9Q4 " <br /> I % <br /> 1. Connect gages to refrigerant bottle - <br /> and unit as illustrated. <br /> 2. Purge all hoses. <br /> 3. Open bottle. <br /> 4. Stop adding refrigerant when liquid <br /> line temperature and Liquid Gage <br /> Pressure matches the charging chart <br /> Final Subcooling value. <br /> Recover refrigerant if the Liquid Gage Pres- <br /> sure is higher than the chart value. <br /> STEP 7 - Stabilize the system. <br /> 1. Wait 20 minutes for the system condi- <br /> tion to stabilize between adjustments. <br /> Note:When the Liquid Line Temperature and 20 MIN. <br /> Gage Pressure approximately match the chart, <br /> the system is properly charged. <br /> 2. Remove gages. <br /> 3. Replace service port caps to prevent <br /> leaks. Tighten finger tight plus an ad- <br /> ditional 1/6 turn. <br /> STEP 8 -Verify typical performance.
