  • Page 15: View Select

    VIEW Select Press VIEW to cycle through ODDB (outdoor dry bulb), TSH (target superheat), and T1-T2 (middle display - bottom display) ODDB: Live reading of the rear ODDB thermocouple jack. ODDB does not show if set to manual value (page 27). TSH: Live target superheat calculated from ODDB and IDWB.

  • Page 16: Superheat (Sh) And Subcooling (Sc)

    Superheat (SH) and Subcooling (SC) Superheat is the amount of heat added to refrigerant after changing to a vapor in the evaporator Subcooling is the amount of heat removed from refrigerant after changing to a liquid in the condenser View both live at the same time! 1.

  • Page 17: Target Superheat (Tsh)

    Target Superheat (TSH) Compare target superheat (TSH) to actual superheat (SH) when charging fixed orifice air conditioning systems TSH is continually calculated from indoor wet bulb (IDWB) and outdoor dry bulb (ODDB) temperatures IDWB: By default, this is a manually set value of 60.0°F. For a live measurement, assign the optional model JL3RH wireless psychrometer (page 26).

  • Page 18: Deep Vacuum

    Deep Vacuum Follow recommended evacuation practices from equipment manufacturer and training Alarms can be adjusted in the MENU (page 28) 1. Close all manifold valves (including shutoff valve to pump). 2. Setup your tools and equipment (see diagram). Connect HIGH port to liquid line service port. Connect LOW port to suction line service port.
  • Page 19 • Inspect the rubber seals at both ends of your hoses for damage. • Change pump oil before and during the job. Change pump oil on- the-fly without losing vacuum with Fieldpiece vacuum pumps. • When the vacuum pump is blocked, a slow rise that stabilizes may signify moisture is still present in the system.

  • Page 20: Test Tightness (Pressure Test)

    Test Tightness (Pressure Test) After working on a refrigerant-side component of an emptied system, it’s a good idea to pressurize the system with dry nitrogen and check for pressure drops before evacuation 13. Pressurize the system with dry nitrogen. Pressure levels vary with the equipment you’re testing.

  • Page 21: Test For Noncondensables

    Test for Noncondensables If head pressure seems high even after cleaning coils, optimizing airflow, and other routine maintenance, you may have noncondensables trapped in the system Noncondensables can reduce efficiency, performance, and put extra stress on system components Noncondensables can enter the system in many ways, and your initial system service may be following years of poor service that introduced the noncondensables 20.
