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 as well as equipment. To help recognize this information, observe the
following symbols.
Safety Guidelines
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.
CAUTION
DD
Important Notice to Users
The Installation, Operation, and Instruction Manual supplied with each unit must be read thoroughly and completely understood
before installation and operation of the Potter IntelliGen™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.
Do not operate if damage occurred during shipping, handling, or
use. Contact Potter immediately.
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 specied 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, qualied, 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 specied in this manual.

INS-1500/INS-2000 (EU) • 5403653 • REV F • 5/23
The warnings in this manual cover 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 procedure 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 sepa-
rator. 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.

System Overview
Key Terms
Potter IntelliGen™ Nitrogen Generators are specically 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 easy-to-use systems include all air ltration equipment and controls
required to keep the generator operating at peak eciency.
The Potter IntelliGen™Nitrogen Series 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 diuse 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 housing.
Bypass Mode – Most nitrogen generators cannot produce enough nitrogen to completely ll the sprinkler system in 30 minutes
required by NFPA 13. Therefore, they contain valves that allow the nitrogen membrane to be bypassed so the system can be lled
with compressed air. The valve setting that bypasses the nitrogen membrane is called Bypass Mode.
Nitrogen Generating Mode – The valve setting that allows the air to ow through the nitrogen membrane and create nitrogen is
called Nitrogen Generating Mode.
Purging – Purging is dened as the removal of oxygen from the sprinkler system via a purge valve. The purge valve allows some
gas to escape from the system which requires the nitrogen generator to supply nitrogen to maintain system pressure. This process
therefore increases the nitrogen concentration within the system piping over time.
IntelliGen™Controller
The IntelliGen™ Nitrogen Generator Series is the only line of intelligent nitrogen generators for re sprinkler systems. At the heart
of the IntelliGen™units, is the IntelliGen™Controller. The IntelliGen™Controller monitors every aspect of the nitrogen generator
to ensure the unit is performing optimally. The IntelliGen™Controller monitors pressure, runtime, power, connectivity and
operational mode. Using this information and proprietary algorithms, the IntelliGen™Controller can determine if the unit needs
to be in Bypass Mode or Nitrogen Generating Mode. No need to manually change ball valve congurations or worry if the unit
is producing nitrogen. Also, by monitoring the generator activity the controller can indicate the development of sprinkler system
leaks, user interaction, and even if maintenance to the generator is required. Combined with the IntelliPurge®Nitrogen Purge
Valve, the IntelliGen™Nitrogen Generator is the only system that can truly monitor and protect a sprinkler system.
