d. If subcooling is high and superheat is low, adjust TXV
valve to 7 to 9 ºF superheat and remove charge to lower
the subcooling to 7 to 9ºF.
NOTE: Do NOT adjust the charge based on suction pressure
unless there is a gross undercharge.
Disconnect manifold set, installation is complete.
NOTE: Check the Schrader ports for leaks and tighten valve
cores if necessary. Install caps finger-tight.
SUBCOOL FORMULA =
SAT. LIQUID LINE TEMP. - LIQUID LINE TEMP.
SUPERHEAT FORMULA =
SUCT. LINE TEMP. - SAT. SUCT. TEMP.
