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

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

Answer: (C)

The high-pressure cut-out control on a recovery unit is an important safety feature designed to ensure that the system operates within safe pressure limits while evacuating refrigerants. For low-pressure chillers, which typically operate at lower pressures compared to standard refrigeration systems, the high-pressure cut-out is set to prevent excessive pressure in the recovery unit when collecting refrigerants. The setting of 10 psig is typically determined based on the operational characteristics of low-pressure chillers, where exceeding this pressure can indicate a problem or significantly hinder the recovery process. Setting the high-pressure cut-out at 10 psig allows the recovery unit to safely collect refrigerant without risking system damage or potential leaks due to elevated pressures. Understanding this setting is crucial for technicians to ensure both safety and efficiency during the recovery process. It reflects industry standards and practices aimed at effective refrigerant management and environmental protection.
