What pressure setting is required for the high pressure cutout of the recovery machine when evacuating refrigerant from a low pressure chiller?

• A. 20 psi
• B. 30 psi
• C. 10 psi
• D. 5 psi

Answer: (C)

The high-pressure cutout setting for the recovery machine when evacuating refrigerant from a low-pressure chiller is set at 10 psi. This specific setting is crucial because low-pressure chillers operate at lower pressure levels than standard systems, and the recovery process must ensure that the refrigerant is removed effectively without reaching high pressure, which could lead to equipment damage or ineffective recovery. Setting the high-pressure cutout at 10 psi allows the recovery machine to safely operate within the pressure limits of low-pressure systems, ensuring operational safety and efficiency. This helps to prevent scenarios where the machine might attempt to recover refrigerant under conditions that deviate from safe and effective performance parameters for the chiller type being serviced.
