Optional Pumpout Safety Control Settings (Figure 40)

The optional pumpout system high-pressure switch should open at 220 ± 5 psig (1517 ±

34 kPa) and should reset automatically on pressure drop to 190 psig (1310 kPa) for HCFC-22

machines. For machines using HFC-134a, the switch opens at 161 psig (1110 kPa) and closes

at 130 psig (896 kPa). Check the switch setting by operating the pumpout compressor and

slowly throttling the pumpout condenser water.
