expected due to differences in installations.
Signifi-
cant differences could mean that the system is
not properly charged or that a problem exists with
some component in the system.
Pressures higher
than those listed indicate that the system is over-
charged. Pressures lower than those listed indicate
L = Liquid S = Suction
Values provided above are typical pressures. Indoor unit matchup, indoor air quality, and indoor load will cause
pressures to vary.
that the system is undercharged. Verify adjusted
charge using the approach method.
4. Use the same digital thermometer to check liquid line
temperature.
