Fieldpiece S365 - Charging Jacket for TXV Systems - Manual (Page 2)

If your subcooling is more than one
degree over the target subcooling,
you are overcharged.
EXAMPLES
Target subcooling = 12°F and your
measured subcooling is 10°F. You are
OK.
Target subcooling = 12°F and your
measured subcooling is 14°F. You are
overcharged.
Target subcooling = 12°F and your
measured subcooling is 7°F. You are
undercharged.
Please use manufacturer's target
subcooling for comparison.

8 If TXV manufacturer’s data is
available, determine the superheat
range recommended by the
manufacturer. (continued)
9 If there is no manufacturer’s data
available then a superheat between
4° and 25°F is acceptable for a TXV. If
the superheat is outside this range,
and the charge is correctly adjusted
by the subcooling method, there
may be a problem with the TXV.
