and service training information.
1.1 EVERFLO OXYGEN CONCENTRATOR OVERVIEW
The EverFlo Oxygen Concentrator produces concentrated oxygen from room air for delivery
to a patient requiring low flow oxygen therapy. The oxygen from the air is concentrated using
a molecular sieve and a pressure swing adsorption process. The EverFlo Oxygen
Concentrator is not intended to be life supporting or life sustaining.
1.2 SERVICE NOTICE
The EverFlo Oxygen Concentrator is designed so that trained Service Technicians can
perform repair and testing procedures. Only trained and qualified personnel should repair
these products using authorized parts.
1.3 SERVICE TRAINING
Philips Respironics offers service training for EverFlo Oxygen Concentrators. Training
includes complete disassembly of the device, troubleshooting subassemblies and
components, repair and replacement of components, setup of test equipment, and necessary testing. For more

Chapter 2. WARNINGS & CAUTIONS
Warnings and cautions are used throughout this manual to identify possible safety hazards, conditions that may
result in equipment or property damage, and important information that must be considered when performing
service and testing procedures on the EverFlo Oxygen Concentrator. Please read this section carefully before
servicing the EverFlo Oxygen Concentrator. Additional Warning and Cautions can be located in the EverFlo User
Manual.
WARNING
Warnings indicate the possibility of injury to people.
CAUTION
Cautions indicate the possibility of damage to equipment.
2.1 WARNINGS WARNINGS
• For proper operation, yourconcentrator requires unobstructed ventilation. The ventilation ports
are located at the top and bottom of the rear cabinet. Keep the device 6 to 12 (15 to 30 cm)
inches away from walls that could impede adequate airflow to the device. Always make sure
that these areas are not obstructed by items, which may impede ventilation. Do not place
concentrator in a small closedspace.
• Servicing of this device must be referred to an authorized and trained Respironics home care
provider.
• Oxygen generated by this concentrator is supplemental and should not be considered life
supporting or life sustaining. In certain circumstances, oxygen therapy can be hazardous; any
user should seek medical advice prior to using thisdevice.
• Oxygen vigorously accelerates combustion and should be kept away from heat or open flame.
Not suitable for use in the presence of a flammable anesthetic mixture with air, with oxygen,
or with nitrous oxide.
• Do not smoke or allow others to smoke or have open flames near the concentrator when it is
in use.
• Do not use oil or grease on the concentrator or its components as these substances, when
combined with oxygen, can greatly increase the potential for a fire hazard and personal injury.
• Do not use the concentrator if either the plug or power cord is damaged. Do not use extension
cords or electricaladaptors.
• Do not attempt to clean the concentrator while it is plugged into an electrical outlet.

WARNINGS
• Avoid handling the molecular sieve material. Respironics recommends the return of the sieve
canister assembly to Respironics for any service that involves sieve disposal.
• Use extreme caution when handling the compressor capacitor as it holds an electrical charge
until is it properlydischarged.
• Device operation above or outside of the voltage, LPM, temperature, humidity and/or altitude
values specified may decrease oxygen concentrationlevels.
• If the EverFlo Oxygen Concentrator has been subjected to sub-freezing temperatures for an
extended period, it should be allowed to warm up to the stated operating temperatures before
power up. Failure to do so could result in improper performance and or alarm conditions until
the device reaches normal operating temperatures.
2.2 CAUTIONS
CAUTIONS
U.S. federal law restricts this device to sale by or on the order of a physician.
Do not place liquids on or near thedevice.
If liquid is spilled on the device, turn the power off and unplug from electrical outlet before attempting to
clean up aspill.
When using liquid leak detector, be careful not to allow it to contact electrical parts.
Make sure connections of fittings, tubing, and hoses aresecure.
Be cautious when using thread sealants because they can cause extensive damage to the internal parts
of the device if allowed within tubing orfittings.

Each EverFlo unit is measured in the factory with an Oxygen Analyzer that measures oxygen concentration with an
accuracy specification of +/- .1 %. When
using an Oxygen Analyzer with an accuracy specification of +/- 2 % to test
the Oxygen Concentration for an EverFlo Oxygen Concentrator, you may receive
inaccurate readings below the
acceptable pass criteria for the device. This 2% offset should be taken in to consideration when determining if the
EverFlo is
functioning properly. A more accurate Oxygen Analyzer may also be used for a more precise
measurement of the oxygen purity. As an example, a unit could be
measured in the factory with the +/- 1% Oxygen
Analyzer to measure 91.1%. If this same unit is then measured with a +/- 2% Oxygen Analyzer, the reading could
display a result of 89.1%. With the +/- 2% Oxygen Analyzer, it may inaccurately look like the unit falls below the 90-
95.5% specification, when in fact the unit is within specification.
Refer to User Manual (1041063) for classification, standards compliance, and EMC requirements.

Chapter 4. THEORY OF OPERATION
This section describes the theory of operation for the EverFlo Oxygen Concentrator.
4.1 PNEUMATIC OPERATION
Refer to Figure 4-1 while reading the following discussion.
The room air is drawn into the unit through the air inlet filter by the compressor. The compressed air is routed to
the sieve beds through an electronically controlled Solenoid Valve Assembly. The Solenoid Valve alternates the
airflow to a pair of sieve beds that allows Oxygen production. The Solenoid Valve Assembly also alternates the
flow through the sieve beds to allow purging of the Nitrogen molecules from the sieve beds.
At startup, the valve/solenoid is de-energized allowing compressed air to flow through both sieve beds until the
pressure sensor builds up to switching pressure. At switching pressure, a 12-volt signal is received at the
valve/solenoid closing off the input and allowing the compressed air to cycle through one of the sieve beds. As
the air is cycled through one of the sieve beds, the molecular sieve material traps the Nitrogen molecules from
the air and allows the Oxygen enriched air to flow through the sievebed.
At 5 liters of flow, approximately 1/3 of the Oxygen enriched air enters the product tank and the other 2/3 of the
Oxygen enriched air is passed through an orifice in the sieve bed to purge the trapped Nitrogen molecules from
the sieve bed, allowing the sieve material to be ready for Oxygen production during the next cycle.
The concentrated Oxygen is stored in the product tank. The product tank is continuously filled with concentrated
Oxygen and the output from the product tank is regulated at 5.5 psig nominal. The product tank pressure is
continuously monitored using a pressure sensor. The stored Oxygen is delivered to the patient through a
pressure regulator, an externally adjustable flow meter and a microbial filter.
NOTE
In the beginning, the 230V units, had an orifice built into the purge valve. The
electronically controlled purge valve controls the Oxygen flow timing from one sieve
bed to the other based on the flow meter setting.
