The 1 3 pegs are 13mm ( in.) long, 1mm ( in.) apart and are 2 mounted on a white base. See Figure 8. LOCKOUT CONTROL Any one of four conditions will put the system into a lock-out condition during the heating or cooling mode: 1. The discharge line temperature reaches 124°C (255°F) (102°C [215°F] reset) or, 2. The discharge pressure reaches 2770 kPa (398 PSIG

Since the moisture on an indoor coil may vary greatly, measuring the pressure drop across a wet coil under field conditions would be inaccurate. To ensure a dry coil, the compressors should be de-energized while the test is being run. 4. Knowing the pressure drop across a dry coil, the actual airflow through the unit can be determined from the curve in Figure 11. WARNING:Failure to properly
