Safety Guidelines
This manual contains safety information that is important to know and understand. This information is provided for the safety
of installers, operators, and users of the Potter Nitrogen Generator. To help recognize this information, observe the following
symbols.
Danger indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.
Warning indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious injury.
Caution indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury.
Notice indicates important information, that if not followed may cause damage to equipment or property.
Important Notice to Users
The Installation and Owner’s Manual supplied with each unit must be read thoroughly and completely understood before
installation and operation of the Potter Nitrogen Generator. All appropriate safety standards for handling of gases as determined
by local or national laws and regulations should be followed at all times.
Unpacking
After unpacking unit, carefully inspect all parts and equipment for any damage that may have occurred during transit. Make sure
to tighten ttings, bolts, etc. before putting unit into service.
General Safety Information
Important: Read all of the safety information in this manual before operating this equipment. Use of the equipment in a manner
not specied within this manual may impair the protection provided by the generator and could result in an unplanned release of
pressure, which may cause serious injury or damage. Only competent personnel, who have been trained, qualied, and approved
by Potter Electric Signal Company should perform commissioning, servicing, and repair procedures.
When handling, installing, or operating this equipment, personnel must employ safe engineering practices and observe all related
local regulations, health, and safety procedures, and legal requirements for safety.
Ensure that the equipment is depressurized and electrically isolated, before carrying out any of the scheduled maintenance
instructions specied in this manual.
D
Do not operate if damage occurred during shipping, handling, or
use. Contact Potter immediately.

Manual: NGP-1000D-M1/M2/M3
The warnings in this manual cover the most known potential hazards, but by denition cannot be all-inclusive. If the user employs
an operating procedure, item of equipment, or a method of working that is not specically 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 classied as non-hazardous for transportation purposes and as non-ammable for re regulations. This equipment
is for indoor use only. Do not operate outdoors.
Specic 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.

Manual: NGP-1000D-M1/M2/M3
The Potter Nitrogen Generator operates using membrane technology. The smaller oxygen and water vapor molecules can pass
through (permeate) the membrane quickly. The larger nitrogen molecules are less likely to diffuse through the separator tubes;
therefore, they continue downstream to the separator outlet. The permeated molecules are discharged to the atmosphere through a
vent in the separator casing.
The Potter Nitrogen Generator is specically designed to provide clean, dry, high purity nitrogen for use in re protection
sprinkler systems. The generator is a fully assembled package ready to be connected to a new or existing re sprinkler system
using a factory pre-engineered air compressor. These turn-key systems include all air ltration equipment required to keep the
generator operating at peak efciency.

The Potter Nitrogen Generator creates a 30% to 40% oxygen stream which may pose a ammability problem in
an oxygen-sensitive environment. Pipe per installation requirements and ensure the area surrounding the nitrogen
generator is adequately ventilated.
The Potter Nitrogen Generator should always be installed in an adequately ventilated room. Nitrogen is nontoxic
and largely inert. Rapid release of nitrogen gas into an enclosed space displaces the oxygen and can cause an
asphyxiation hazard. Inhalation of nitrogen in excessive concentrations can result in unconsciousness without any
warning symptoms.
