NS SPLIT INSTALLATION MANUAL
Refrigeration (continued)
1.Once the proper superheat setting has been achieved, replace and tighten the seal cap.
Warning: There are 8 total (360°) turns on the superheat adjustment stem from wide open to fully closed. When adjusting the superheat stem clockwise (superheat increase) and the stop is reached, any further clockwise turning adjustment will damage the valve.
Determining Subcooling
1.Measure the temperature of the liquid line on the small refrigerant line (liquid line) just outside the split cabinet. This location will be adequate for measurement in both modes unless a significant temperature drop in the liquid line is anticipated.
2.Measure the liquid line pressure by attaching refrigerant gauges to the schrader connection on the liquid line service valve.
3.Convert the pressure obtained in Step 2 to the saturation temperature by using the
4.Subtract the temperature in Step 1 from the temperature in Step 3. The difference will be the subcooling value for that unit. Refer to the tables on page 24 for subcooling ranges at specific enter water conditions.
