Operating Instructions
Before OperatingThis user manual serves as your reference to help
you operate and maintain the device. If you haveany questions or concerns please call your homecare provider.
Important! DO NOT attempt to operate the Companion 5 without first reading the Safety Guidelines
section of this manual. Please follow all of theoperating instructions. Please observe all Warnings
on the device and in the Users Manual. In order toreduce the risk of fire, personal injury and serious
damage to the Companion 5, please observe all of
the safety precautions.
The CAIRE Companion 5 does not create its own
oxygen. It produces highly concentrated oxygenfrom surrounding room air and delivers it to you.
As it naturally exists, room air contains approximately only 21% oxygen by volume.
Room air is drawn into the concentrator by acompressor. The air then travels through a seriesof filters and a molecular sieve bed that chemically adsorbs nitrogen molecules. As a result, theoxygen-enriched air that exits the concentrator isdelivered at 87–95% oxygen by volume.
WARNING: CLEAN THE CABINET, CONTROL PANEL, AND POWER CORD ONLY
WITH A MILD HOUSEHOLD CLEANERAPPLIED WITH A DAMP (NOT WET)
CLOTH OR SPONGE, AND THEN WIPE
ALL SURFACES DRY. DO NOT ALLOWANY LIQUID TO GET INSIDE THE
DEVICE. PAY SPECIAL ATTENTION TO
THE OXYGEN OUTLET FOR THE CANNULA CONNECTION TO MAKE SURE IT
REMAINS FREE OF DUST, WATER, AND
PARTICLES.
CAUTION: Do not allow either the air
intake or the air outlet vents to become
blocked. This can cause the Oxygen
Concentrator to overheat and impair
performance. Do not operate the Oxygen
Concentrator without the air intake filterin place. If a second filter is provided,
insert the “replacement” filter before you
clean the dirty filter. Clean the dirty filter
in a warm soap and water solution thendry thoroughly prior to use.

NOTE: If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the
ME EQUIPMENT OR ME SYSTEM may be reduced to 1m. The 1 m test distance is permitted by IEC 61000-4-3.
a)For some services, only uplink frequencies are included.
b)
The carrier shall be modulated using a 50% duty cycle square wave signal.
c)
As an alternative to FM modulation, 50% pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it would be worst case.
The manufacturer should consider reducing the minimum separation distance, based on risk management,
and using higher immunity test levels that are appropriate for the reduced minimum separation distance.
Minimum separation distances for higher immunity test levels should be calculated using the following
equation:

Where P is the maximum power in W, d is the minimum distance in m, and E is the immunity test level inV/m.
If the ME EQUIPMENT or ME SYSTEM complies with higher immunity test levels or this test, the 30
cm minimum separation distance in 5.2.1.1 f) may be replaced with minimum separation distances calculated from the higher immunity test levels.
