Manual: NGP-300D
The warnings in this manual cover the most known potential hazards, but by denition cannot be all-inclusive. If the user employs
an operating procedure, item of equipment, or a method of working that is not specically recommended by Potter Electric Signal
Company, the user must ensure that the equipment will not be damaged or become hazardous to persons or property.
Nitrogen is not a poisonous gas. However, in a concentrated form, there is a risk of asphyxiation. The generator produces a ow
of nitrogen and oxygen enriched air which quickly disperses in the atmosphere. However, do not directly inhale the output gas
from the outlet pipe.
The generator is classied as non-hazardous for transportation purposes and as non-ammable for re regulations. This equipment
is for indoor use only. Do not operate outdoors.
Specic procedures must be developed for maintenance of the equipment on which the membrane separator is located.
Appropriate labels must be continuously displayed in all areas where personnel might be exposed to a nitrogen atmosphere
under normal or upset condition.
Do not attempt to disassemble the nitrogen membrane
separator. Equipment damage may occur and cause the
system to function incorrectly.
Operation of the nitrogen membrane separator above the
rated design pressure may be hazardous. Do not connect it
to compressed air sources that can exceed its maximum
rated pressure without installing appropriate pressure
controls and safety relief devices in the compressed air
supply line.
