Page 15 HOLDING CHARGE AND STORAGE SGC/SGX compressors are pressure and leak tested at the Johnson Controls–Frick factory and then thoroughly evacu- ated and charged with dry nitrogen to ensure integrity dur- ing shipping and short term storage prior to installation.
Advanced control systems like the Frick Quantum HD will Other connections are available for instrumentation, oil monitor the oil pressure in many more ways in order to return, and service as noted on the Dimensional Outline keep the compressor running beyond these basic limits.
