Using a digital psychrometer, measure the return air wet-bulb temperature at the unit just before the coil. Also measure the outdoor dry-bulb tem-
perature. Use these temperatures to locate the target superheat on the charging table. Do not attempt to charge the system if these conditions fall
outside of this charging table.
ADD refrigerant to DECREASE total superheat. REMOVE refrigerant to INCREASE total superheat. Always allow 10 to 15 minutes of operature
after any refrigerant or air flow change prior to determining the final superheat.
STEP 9 - Record System Information for refer-
ence.
Record system pressures and temperatures
after charging is complete.
