Commissioning & Safe Start-Up Sequence
This procedure must be followed to ensure the nitrogen generation system is operating
correctly and in a safe state. It is mandatory that this procedure be followed after any
service operation has been carried out.
All servicing and repair must be carried out by Peak Gas Generation or an authorised
Peak partner.
After servicing and restart of the system, the tanks should build pressure to the factory
set value (visible on external pressure gauges) and the i-Flow and Air Dryer should
initialise as per their respective user manuals, showing no errors or warnings.
NOTE: Where the below instructions make reference to the i-Flow Nitrogen Generator
or the Refrigerant Dryer, please refer to the individual User Manual documents
(separate, but included with system) provided.
With reference to Pneumatic diagram (Figure 7):
1. Once the Generator has been installed, ensure all valves (1-7) are shut, DO NOT Switch on
the power to the i-Flow Generator immediately. First Switch on the Air Dryer (note: this
includes power to all Air Filtration equipment). Remove the blank plug from and open valve
2. Partially & slowly open the Air supply valve (1), to allow the inlet compressed air to vent &
purge any remaining moisture from the newly installed pipework & equipment.
3. After 5-10 minutes shut valve (2) replacing the blank plug and slowly fully open valve (1).
This will introduce the compressed air supply up to the i-Flow Generator inlet. At this point
valve (1) should be open and valves (2-7) should all be in the closed position. The Inlet
pressure will be indicated on the Carbon Tower gauge.
4. Open Valves (3) & (4) to put the N2 Process Tank online to the i-Flow Generator.
5. The power to the i-Flow generator can now be turned on. On first start up, air will be
introduced to Column 1 and the front panel gauge will slowly start to rise. The front panel
display will have an orange background and show a message “BYPASS ACTIVE” “HIGH
OXYGEN”. During this period, the i-Flow Generator will begin to cycle and will automatically
vent poor quality gas internally through the built in Bypass feature. Normal cycle is as
follows: Column 1 gauge will start to rise in pressure, after approx. 40 seconds the Columns
will briefly “EQUALIZE” and the pressure on Column 1 and 2 gauges should level out.
Column1 will then vent rapidly to zero and Column 2 will continue to rise slowly. During this
process, the TANK pressure gauge should continue to slowly rise.
6. Allow the N2 Process Tank to reach pressure and stabilise (timing will vary depending on
the starting contents of the process tank). From first start-up with air in the tank, it is likely
to take 8 to 10 hours to purge the oxygen to an acceptable level. The actual oxygen content
(in parts per million) is displayed on the front panel screen. Once the oxygen content drops
below the required level, the system will automatically exit BYPASS mode.. The front panel
screen will remain with an orange background for 24hrs from first power on, and during this
time all pressure and purity alarms are disabled.
