Measure Liquid Line Temperature and
Refrigerant Pressure at service valves.
Determine total refrigerant pipe length
and height (lift) if indoor section is above
the condenser. Plot the intersection of
the two points on the Curve Selection
Chart to determine which curve to use.
Plot the pressure and temperature on
the TXV Charging Curve.
If the lines cross above the curve remove
refrigerant, if below curve add refrigerant.
Whenever charge is removed
or added, the system must
be operated for a minimum
20 minutes to stabilize before
additional measurements can
be made.
When system is correctly
charged refer to System
Performance Curves to verify
charge and performance.

COOLING PERFORMANCE CAN BE CHECKED WHEN THE OUTDOOR TEMP IS ABOVE 65 DEG F.
TO CHECK COOLING PERFORMANCE, SELECT THE PROPER INDOOR CFM, ALLOW PRESSURES TO STABILIZE. MEASURE INDOOR WET BULB
TEMPERATURE, OUTDOOR TEMPERATURE, DISCHARGE AND SUCTION PRESSURES. ON THE PLOTS LOCATE OUTDOOR TEMPERATURE (1);
LOCATE INDOOR WET BULB (2); FIND INTERSECTION OF OD TEMP. & ID W.B. (3); READ DISCHARGE OR SUCTION PRESSURE IN LEFT
