The typical setting for the high-pressure cut out control on recovery unit used for evacuating refrigerant from a low-pressure chiller is

• A. 5 psig
• B. 15 psig
• C. 10 psig
• D. 20 psig

Answer: (C)

The high-pressure cut-out is a safety feature that stops the recovery unit if the pressure on the discharge side gets too high, protecting the equipment and the refrigerant from overpressure. When you’re evacuating refrigerant from a low-pressure chiller, the pressures involved on the high side stay relatively low. A setting around 10 psig provides a safe threshold that prevents damage or unsafe conditions without interrupting the evacuation process too early. If the setting were much higher, you risk overpressuring components; if it were much lower, the unit would trip too often and slow down the recovery. So, around 10 psig is a typical, practical choice for this scenario.
