Section 1 - Safety & Warnings
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 Nitrogen enerator. 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 Nitrogen enerator. 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 fittings, 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 specified 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, qualified, and approved by eneral Air Products 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 specified in this manual.

NOTICE
Do not operate if damage occurred during shipping, handling,
or use. Contact eneral Air Products immediately.
WARNING

1-800-345-8207
The warnings in this manual cover the most known potential hazards, but by definition cannot be all-inclusive. If the user em-
ploys an operating procedure, item of equipment, or a method of working that is not specifically recommended by eneral Air
Products, 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 flow 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 classified as non-hazardous for transportation purposes and as non-flammable for fire regulations. This
equipment is for indoor use only. Do not operate outdoors.
Specific 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 atmos-
phere under normal or upset condition.
WARNING
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.
NOTICE
Do not attempt to disassemble the nitrogen membrane
separator. Equipment damage may occur and cause the
system to function incorrectly.

Section 2 - System Overview
The Nitrogen enerator 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 atmos-
phere through a vent in the separator casing.
The Nitrogen enerator is specifically designed to provide clean, dry, high purity nitrogen for use in fire protection sprin-
kler systems. The generator is a fully assembled package ready to be connected to a new or existing fire sprinkler system
using a factory pre-engineered air compressor. These turn-key systems include all air filtration equipment required to keep
the generator operating at peak efficiency.

Section 3 - Before Going To The Job Site
1. Find a location for the nitrogen generator to be installed meeting these requirements:
2. Run a dedicated electrical circuit with an electrical disconnect switch to sprinkler room.
Dimensions 62” x 44” x 33” (H x W x D)
Dry, clean, and well-ventilated
Ambient temperatures above 50° F at all times
Access to front for service
Conveniently located near fire sprinkler system connections
Conveniently located near drain
WARNING
The Nitrogen enerator creates a 30% to 40% oxygen stream which may pose a flammability problem in an oxygen-sensitive
environment. Pipe per installation requirements and ensure the area surrounding the nitrogen generator is adequately ventilated.
The Nitrogen enerator 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.
