2 Safety
The safety guidelines below may not cover all situations. If there are concerns or
questions, please contact Proton OnSite technical Service or check with local authorities.
THE LCMS MEMBRANE GENERATORS ARE A LABORATORY
INSTRUMENT DESIGNED FOR OPERATION BY TRAINED PERSONNEL.
UNSAFE CONDITIONS MAY RESULT IF THE GENERATOR IS OPERATED
BY UNTRAINED PERSONNEL OR PERSONNEL UNFAMILIAR WITH
NITROGEN AND ENRICHED OXYGEN SAFETY.
ALL PERSONNEL HANDLING, USING OR MAINTAINING THIS
GENERATOR MUST EMPLOY SAFE WORKING PRACTICES AND OBSERVE
ALL RELEVANT LOCAL HEALTH AND SAFETY REGULATIONS.
2.1 Using Nitrogen Gas
Nitrogen is an odorless, colorless nontoxic gas that can displace the air content of the
workspace and increase the risk of asphyxiation if not used properly.
Never directly inhale the gas produced and check gas connections with a liquid leak
detector at initial installation or after a service event where gas plumbing has to be
disconnected.
2.2 Oxygen Enrichment
As a byproduct of the nitrogen production, the generator has the ability to increase the
oxygen content levels greater than 23% thus creating an “oxygen enriched” atmosphere if
minimum ventilation requirements are not present within the space the generator is
installed.
In order to determine if the ventilation is sufficient, please perform the calculations in
Table 3. The units used shall be in cubic feet. Be sure to use the same measurement
system for all calculations during this process.
The calculation makes a conservative estimate by assuming the following: air input to
nitrogen out is 2:1. The calculation also assumes that the membrane is 100% efficient in
removing oxygen from the nitrogen product, therefore releasing the maximum O2 content
to the environment the unit is installed.
If the air exchange rate of the installation location is unknown, please contact your
laboratory or facilities manger to determine the correct air exchange rate to use for the
calculation.
PD-0100-0066 Rev. A
--UNAUTHORIZED COPIES PROHIBITED--
Page 12 of 27
NiGen Membrane LCMS Laboratory Nitrogen Generators
Installation, Operation & Maintenance Manual
If calculated oxygen enrichment exceeds 23%, Proton OnSite recommends increasing the
area ventilation rate or relocating the generator to a more suitable area.
Calculate room volume
V: __________ room volume in cubic feet
Enter area air ventilation rate
R: __________ room air exchanges per hour
Multiply V x R
A: __________
Multiply A x 21%
B: __________
Insert values A and B into the appropriate equation for your specific model to determine
potential oxygen enrichment. If the oxygen concentration exceeds 23%, Proton recommends you
improve area ventilation or relocate equipment to a more suitable area.
For MODEL LCMS 34:
O2 concentration % =
For MODEL LCMS 60:
O2 concentration % =
For MODEL LCMS 120:

25+рќ‘©
O2 concentration % =

EXAMPLE: A room that is 10 feet by 12 feet with an 8 foot ceiling has a volume V of 960 cubic
feet. If the room ventilation rate is 4 exchanges per hour, then value A is 3840 and value B is
806. For the model LCMS 34, the potential O2 concentration will be 21.3%, less than the 23%
enriched oxygen threshold value. No area change is needed.
Table 3 Oxygen Concentration Calculation
2.3 Safety Devices
MAXIMUM PRESSURE: In case of anomalous air inlet pressure surge, a safety valve
prevents the generator pressure from exceeding 12.0 bar (175 psi). The air will be vented
within the enclosure.

4 Installation
TURN OFF AIR SUPPLY PRIOR TO INSTALLATION
It is recommended that the air supply to the generator be protected from liquid
condensation by installing a moisture trap upstream of the Nitrogen Generator. The trap
should be installed in a manner that it acts as a drip leg on the supply of air (an example
is shown in Figure 3.
To Generator
Figure 3 Example of moisture trap
It is also recommended that an air isolation valve be installed up stream of the unit to
allow for safe maintenance.
4.1 Pneumatic Connections
The Pneumatic Connections for the Nitrogen Generator should be plumbed with piping or
tubing that is suitably rated for the working pressure and flow rates of the gases being
used.
4.1.1 Nitrogen Outlet
When mounted on the wall, the air inlet is on the right side of the nitrogen generator (See
Figure 1). The unit is equipped with a 3/8” female NPT fitting. Fittings have been
provided to adapt this to either a fractional or a metric tube, depending upon your
location.

4.1.2 Air inlet
When mounted on the wall, the air inlet is on the left lower side of the nitrogen generator
(See Figure 1). The unit is equipped with a 3/8” female NPT fitting. Fittings have been
provided to adapt this to either a fractional or metric tube, depending upon your location.
4.1.3 Condensate Drain
When mounted on the wall the condensate drain is on the right lower side of the
nitrogen generator (See Figure 1). The connection is a 3/8” OD push to connect type
fitting. 7.6 meters (25 feet) of 3/8” tubing has been provided to allow this drain to be
routed to a suitable drain location.
4.2 Packaging Disposal
It is recommended to keep the packaging, should the generator need to be returned to the
factory for any reason. If the packaging has been discarded and the generator needs to be
returned to the factory, a charge will be assessed for the shipment of new packaging
materials. All returns must be made in the original packaging or a Proton OnSite
approved substitute.

5 Operation
During operation the Nitrogen Generator delivers Nitrogen gas at a preset pressure. This
set pressure can be read on the front product pressure gauge. This gauge is visible
through a window cutout in the front cover. The product pressure can be adjusted to any
desired pressure up to 6.9 bar (100 psig) by adjusting the product pressure regulator
within the generator (see section 5.1.)
Safety glasses should be worn whenever the front cover of the Nitrogen Generator is
removed. Components within the Nitrogen Generator can be pressurized with air
up to 10 bar (145 psig).
If the nitrogen demand exceeds the rating of the Nitrogen Generator, then the pressure
across the membrane will begin to droop and will negatively affect the purity of the
nitrogen delivered. If you are finding that you are using more Nitrogen than the unit is
capable of delivering, please contact your sales representative. Options are available to
expand the output capacity of your Nitrogen Generator.

6 Maintenance
Maintenance of the Nitrogen Generator can be performed within a half hour, minimizing
down time.
The manual drains on the carbon filter housings described below should be checked
periodically to ensure that excessive amounts of moisture are not getting past the
coalescing element.
6.1 Filter Maintenance
Within the generator, three filter elements will need replacement at a minimum interval
of every six (6) months. The frequency of filter element change will ultimately be
determined by quality of the input air; therefore, will be site specific. The filter element
locations are shown in Figure 5. An annual maintenance kit is available that provides
two sets of filter elements to satisfy the minimum change interval requirement. Please
contact Proton OnSite for part number and pricing of this kit.
