SECTION 1—IMPORTANT SAFEGUARDS
SECTION 1—IMPORTANT
SAFEGUARDS
In order to ensure the safe installation, assembly and operation of the XPO Portable
2
Concentrator these instructions MUST be followed.
ꢀ WARNING
SECTION 1 - IMPORTANT SAFEGUARDS contains important information for the safe
operation and use of this product.
Operating Information
ꢁ DANGER
A spontaneous and violent ignition may occur if oil, grease, greasy substances, or
petroleum based products come in contact with oxygen under pressure. These
substances MUST be kept away from the XPO portable concentrator, tubing and
2
connections, and all other oxygen equipment. DO NOT use any lubricants unless
recommended by Invacare.
To Reduce The Risk Of Burns, Electrocution, Fire Or
Injury To Persons
DO NOT come in contact with the concentrator while wet.
DO NOT place or store product where it can drop into water or other liquid.
DO NOT reach for product that has fallen into water. Unplug IMMEDIATELY.
Avoid creation of any spark near medical oxygen equipment. This includes sparks
from static electricity created by any type of friction.
NEVER drop or insert any object or liquid into any opening.
For optimum performance, Invacare recommends that each concentrator be On, in auto-
pulse mode, and running for a minimum of 5 minutes. Shorter periods of operation may
reduce maximum product life. Refer to Checking O Purity on page 14 for auto-pulse
2
mode.
A product should NEVER be left unattended when plugged in. Make sure XPO is Off
2
when not in use.
The XPO MUST be used in an upright position.
2
DO NOT connect the concentrator in parallel or series with other oxygen concentrators or
oxygen therapy devices.

SECTION 1—IMPORTANT SAFEGUARDS
Radio Frequency Interference
This equipment has been tested and found to comply with EMC limits specified by IEC/
EN 60601-1-2. These limits are designed to provide a reasonable protection against
electromagnetic interference in a typical medical installation.
Other devices may experience interference from even the low levels of electromagnetic
emissions permitted by the above standards. To determine if the emissions from the XPO
2
are causing the interference, turn the XPO Off. If the interference with the other device(s)
2
stops, then the XPO is causing the interference. In such rare cases, interference may be
2
reduced or corrected by one of the following measures:
• Reposition, relocate, or increase the separation between the equipment.
• Connect the equipment into an outlet on a circuit different from that to which the
other device(s) is connected.

ꢀ WARNING
When accessing the XPO remember that battery power is still being applied to the
2
internal (PCB) printed circuit board. Care MUST be taken to minimize contact with the
PCB. DO NOT use any kind of tool (screwdriver, pliers, etc.) when working on the
internal structure, otherwise, injury and/or damage may occur. Battery power remains on
the PCB as long as the battery connection is made to the PCB.
NOTE: For this procedure, refer to FIGURE 2.2 and FIGURE 2.3 on page 10.

Replacing the Battery
CAUTION
Before handling the P.C. board, ensure you are properly grounded to prevent static
damage to the components of the board. A static cuff MUST be worn and properly
grounded using an alligator clip. Electrical conduit or a water pipe is normally sufficient
when a known good ground in unavailable. Care should be taken to ensure that the
alligator clip contacts a bare metal surface.
NOTE: For this procedure, refer to FIGURE 2.5.
1. Perform the steps in Accessing XPO on page 9.
2
2. Remove the inlet filter with tubing attached from the holder.
3. Disconnect the battery wiring harness from the PC board.
4. Remove the battery from the thermal pad and battery tray.
NOTE: The thermal pad is between the battery and the bottom of the tray. It is a soft “dough-like”
material that adheres to the tray. If thermal pad is damaged or pulled up during battery removal it
MUST be replaced.

Re-assembling the XPO
2
NOTE: For this procedure, refer to FIGURE 2.3 on page 10.
1. Carefully, re-install the front cover onto the XPO .
2
2. Turn the XPO On to ensure proper operation.
2
3. Turn XPO Off.
2
4. While holding the unit together, position the XPO so that the back panel is facing up
2
(Detail “A” in FIGURE 2.3).
5. Install four mounting screws and secure the two sections of the XPO together (Detail
2
“A” in FIGURE 2.3). Securely tighten.
6. Remove the glue residue by applying 91% isopropyl alcohol, and wiping with a clean
cloth. Make sure the surface is dry and free of any residue. This will ensure a good seal
for the new label.
7. Install replacement label on the top of the XPO so that it adheres to both the front and
2
rear sections.

SECTION 3—CHECKING O PURITY
2
SECTION 3—CHECKING O PURITY
2
NOTE: Although the XPO offers pulse dose only, the oxygen purity can be checked with a hand
2
held oxygen analyzer.
NOTE: Oxygen purity should be checked every 4,320 hours.
1. Turn the unit On.
2. Press the “+” button to increase the flow to setting 5.
3. Simultaneously press and hold the “+” and “battery gauge” buttons until the #5 BLUE
indicator light blinks. This is your indication that the unit is now in auto-pulse mode.
NOTE: The unit will remain in auto-pulse mode until it is set to a lower flow setting or is turned
off.
4. Connect a standard hand held oxygen analyzer to the outlet port.
5. Follow the directions provided by the analyzer manufacturer. Some analyzers will
also measure flow and pressure, but only if connected to a continuous flow of oxygen
(so these options are not usable on this pulse only unit).
NOTE: The purity reading may fluctuate slightly due to the pulse flow. It is recommended that you
record a high and a low over a 60 second time period. The XPO is functioning properly when the
2
purity levels are above 87%, after the 5 minute warm-up period.

SECTION 4—ERROR CODES
SECTION 4—ERROR CODES
The XPO has dozens of alarms that are being monitored on a continuous basis. The
2
alarms are grouped into four main categories:
• Common Alarms: These are alarms for which the patient, or the provider, can take
action to eliminate the issue. These alarms, and the corrective steps, are fully
explained within the Owner’s Manual (OM).
• Operating Alarms: This alarm group centers on the sieve beds and the PSA
process. These are alarms for which there is no corrective action available to either
the patient or the provider. However, there are sub-codes that can be accessed to
help the Invacare service and repair centers.
• Compressor Alarms: This alarm group centers on the compressor operation. These
are alarms for which there is no corrective action available to either the patient or
the provider. However, there are sub-codes that can be accessed to help the
Invacare service and repair centers.
• System Alarms: This alarm group centers on internal software monitors. These are
alarms for which there is no corrective action available to either the patient or the
provider (*). However, there are sub-codes that can be accessed to help the
Invacare service and repair centers.
To access the Sub-Alarm codes, the unit first has to be in an alarm condition with multiple
flow level LEDs illuminated. While in this condition, the Plus (+) and Minus (-) flow
setting buttons should be pushed and held. As long as both these buttons are being
pushed, a different set of flow LEDs will illuminate. This alternate set of illuminated LEDs
is the sub-alarm code. Once the Plus and Minus buttons are released, the original alarm
code will return. Once the unit is turned off, the alarm codes displays will be reset. All the
alarms should be reset and the unit turned back on to see if the unit can self-correct the
problem. If the alarms persist, please contact your nearest Invacare repair center.
