This device supplies highly concentrated oxygen
enriched product gas that promotes rapid
burning.
DO NOT allow smoking or open flames within the
same room of this device.
Failure to observe this warning can result in
severe fire, property damage, and / or cause
physical injury or death.
Oxygen accelerates the combustion of flammable
substances.
DO NOT use oil, grease, petroleum based or other
flammable products on the device.
This device is intended for industrial use. It
should be placed in a well-ventilated area, free
from smoke and atmospheric pollution, where
the intake filter ventilation is not obstructed or
blocked.
DO NOT use in an explosive environment.

DO NOT open the device while in operation.
Failure to observe this warning can result in
electrical shock.
DO NOT remove the cabinets unless you are a
qualified service technician.
DO NOT use extension cords or adapters. Use the
power cord provided.
Check that the electrical characteristics of the
power outlet used match those indicated on the
manufacturer’s plate on the rear panel of the
device.
This unit may be equipped with a polarized plug.
That is one blade wider than the other. If it does
not fit into the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician. Do not
defeat this safety feature.

2 Purpose and Principles of Operation
This device is intended to supply oxygen for applications requiring high concentration. It produces an enriched
product gas by concentrating the oxygen contained in room air.
The operation of the device begins with air being pulled into the external air intake filter. This filtered air enters the
compressor via a suction resonator and fine filter. Pressurized air then exits the compressor and into an electronic
valve system that directs the air into one of two tubes that contain molecular sieve (sieve beds). The molecular sieve
adsorbs (physically attracts) the nitrogen from the air as it is pushed through the sieve beds. This allows the oxygen
enriched product gas to pass through before being delivered to the pressure regulator. As one tube is generating
the product gas, the other is being purged of the adsorbed nitrogen, this process is called pressure swing adsorption
(PSA). After passing through the regulator, the rate of product gas is set by the flow meter adjusting valve. Finally,
it passes through a fine particle filter (product filter) and then exits the device through a fire-resistant outlet.

4 Installation and Operation
The Pro Oxygen Generator is packaged to protect the device from damage while being transported and stored. After
the device is removed from the package, inspect for damage. If damage is detected, please contact your equipment
supplier.
The device should be placed and operated in a space where the Intake Filter Ventilation (7) is not obstructed and
the Power Cord (9) is accessible for easy disconnection but does not present a tripping hazard.

2010-2339NM Rev A 17 July 2018 Page 3 of 4
To use your device safely, follow the directions below.
1. Ensure that the Power Switch (1) is in the “O” (OFF) position.
2. Ensure the Intake Ventilation (7) is not obstructed or blocked.
3. Plug the Power Cord (9) into an outlet of the correct voltage and frequency as defined on the Technical
Label (8).
4. Connect supply tubing, that is rated for oxygen use at the designated pressure, to the Oxygen Outlet (4).
5. Move the Power Switch (1) to the “I” (ON) position.
6. Turn the Flow Knob / Flow Adjustment Knob (5/6) to the desired flow rate.
7. At the end of use, move the Power Switch (1) to the “O” (OFF) position to stop the device.
The required oxygen concentration is normally obtained within five minutes of the start up of the
device.
The oxygen enriched air flow continues for approximately one minute after shut down of the device.
5 Cleaning and Maintenance
Only the outside of the device is to be cleaned. After making sure the Power Switch (1) is in the "O"(OFF) position,
use a soft, dry cloth or, if necessary, a damp sponge with mild soap. Do not use acetone, solvents, abrasive
powders or any inflammable products to clean the cabinet.
The removable Cabinet Air Filter (10) must be cleaned, at least weekly, in warm water and household detergent. It
should be rinsed thoroughly and dried completely before reinstalling. The Inlet Filter (not pictured, located inside
the device) should be inspected monthly and replaced if required – at least annually. The product filter (not
pictured, located inside the device) should only be replaced by a technician if required (not common).
