6.Compare the approach value with those shown in Table

7.If the values do not agree with those provided in Table 7, add refrigerant to lower the approach temperature or recover refrigerant from the system to increase the approach temperature.

Check Charge Using Normal Operating Pressures Use Table 8 to perform maintenance checks. Table 8 is not a procedure for charging the system. Minor variations in these pressures may be due to differences in installations. Significant deviations could mean that the system is not properly charged or that a problem exists with some component in the system.

Approach Values for TXV Systems

Approach value is the liquid line temperature minus the outdoor ambient temperature (± 1°F).

Note: For best results, use the same digital thermometer to check both outdoor ambient and liquid temperatures.
