This test should last for a period of hour. Lower system pressure upon confirmation that item No. has been successful. Minimum test period is hrs. NOTE - Oxygen Free Nitrogen will vary in pressure due to temperature change at a rate of.6 psig per F. PRE-COMMISSIONING METHOD STATEMENT - PHASE TRIPLE EVACUATION PROCEDURE A Micron or Torr gauge must be used for this procedure. Discharge the oxygen-free nitrogen and evacuate the system to a reading of 8000 Microns (8 Torr) using all service valves. Break the vacuum by allowing nitrogen into the applicable inter-connecting pipework port connections (Example: low pressure gas pipe, high pressure gas pipe and liquid line pipe) until a positive pressure is achieved. Evacuate the system to a reading of 000 Microns ( Torr). Break the vacuum by allowing nitrogen into the applicable inter-connecting pipework port connections (Example: low pressure gas pipe, high pressure gas pipe and liquid line pipe) until a positive pressure is achieved. Evacuate the system to a reading of 00 Microns. 6 For a moisture-free system, ensure the vacuum is held without movement for a minimum of hrs. 7 If pressure loss is detected, carry out steps through 6 until no pressure loss is observed. To ensure correct system performance and reliability the above Method Statement (Phase & ) must be strictly followed. Failure to follow these guidelines will result in the warranty being voided.
