(5) Refer to table 4-2 and convert pressure (gage pressure plus 2 psig) to temperature.
(6) To calculate superheat of the expansion valve, deduct the temperature calculated in step (5) from the
temperature indicated on the thermometer attached to the suction line. Superheat of the expansion valve should be 10 F
.5 F (-12.22 C .5 C).
(7) If superheat is 10 F .5 F (-12.22 C .5 C), no adjustment of the expansion valve is necessary.
(8) If superheat is not as specified in step (7), adjust the expansion valve as follows:
(a) Remove seal cap on the side of the expansion valve.
(b) The expansion valve superheat is adjusted by turning the adjusting screw. Turning the adjusting
screw counter-clockwise increases flow and lowers the superheat. Turning the adjusting screw clockwise decreases flow
and raises superheat. Four complete turns will raise or lower the superheat by approximately 2 F (1.1 C). Turn the
adjusting screw to obtain a superheat of 10 F .5 F (-12.22 C .5 C).
(c) Allow the unit to run on "COOL" for at least 20 minutes before adjusting to a new setting.
(d) Calculate the superheat of the expansion valve. If the superheat is now 10 F .5 F (-12.22 C .5 C),
no further adjustment is necessary. If the superheat is not correct, continue the adjustment cycle, allowing at least 20 minutes
between adjustments until the specified superheat is obtained.
