107 °F

STEP 8

 - Verify typical performance.

Refer to System Pressure Tables to verify typical 
performance.

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 Pres-

sure is higher than the chart value.

(Example only - see Pressure Tables)

20 MIN.

STEP 7 

-  Stabilize the system.

1.  Wait 20 minutes for the system condi-

tion 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 ad-
ditional 1/6 turn.
