GENERATION NITROGEN GENERATOR SYSTEM MANUAL
START-UP
IMPORTANT: Make sure the unit has been properly installed according to the Installation
Instructions included in this manual. The unit MUST be vertical for 12 hours before turning the
unit on.
CAUTION:
When the compressor starts, the cooling fan on the heat exchanger should rotate.
If fan is not rotating, turn unit off or damage to the unit could occur.
The generator system is factory set for optimum purity and no adjustments are necessary. The design of the
system is such that the operating temperatures of all components must be controlled to optimize nitrogen
purity. Because of this, it is necessary for the climate control system be energized for a period of 8 hours
prior to releasing nitrogen from the generation system.
The climate control system is preset to cool when the enclosure air temperatures exceed 80°F and heat
when the enclosure air temperature falls below 63°F. The enclosure air is continually cycled through the
system to avoid temperature gradients anywhere in the system.
After all components have been brought within temperature specifications, the generator is ready for use
and the gas space purge operation can begin.

1) Remove "Ship Block" under the compressor (the block provides stability during shipping).
2) Before operating, gas space pressure switch contacts must be set to allow the needle to move (alarm
points protect the needle during transport).
3) Loosen clamp around the needle alarm knobs. A small screw is located on the bottom of the clamp.
4) Adjust the low pressure contact (left knob) to 0.2 psi. Adjust the high pressure contact (right knob) to
5.5 psi.
5) Tighten the clamp.
6) Turn on the main power feed to the generator with appropriate fuse or breaker disconnect.
