Safety Summary; Intended Use - Invacare CHECK O2 PLUS Zusammenbau, Installation Und Gebrauchsanweisung

NOTE: Check all parts for shipping damage. If dam-
age is found, DO NOT use. Contact Carrier/Invacare
for further instructions.

SAFETY SUMMARY

The following recommendations are made for
the safe and proper use of the Invacare Check
O Plus Hand-Held Analyzer:
WARNING
DO NOT install this equipment without first read-
ing and understanding this instruction sheet.
If you are unable to understand these instruc-
tions, contact a healthcare professional,
dealer or technical personnel if applicable
before attempting to install this equipment -
otherwise, injury or damage may occur.
Oxygen rapidly accelerates combustion:
DO NOT smoke while using oxygen.
DO NOT use oxygen in the presence of
flames, sparks, or glowing objects.
Ensure that all items are properly and se-
curely installed.
CAUTION
DO NOT expose any port of the analyzer to
any pressure greater than 68.95 kPa or dam-
age may result to internal components.
DO NOT use the analyzer on pure oxygen
from high pressure cylinders or liquid systems.
DO NOT use the Invacare Check O Plus
Hand-Held Analyzer on any gas stream that
is humidified. Use of the analyzer with water
vapor can cause erroneous readings and in-
ternal damage.

INTENDED USE

NOTE: The Invacare Check O Plus Hand-Held
Analyzer is designed and calibrated for use in mea-
suring unhumidified output gas of an oxygen con-
centrator ONLY.
NOTE: The analyzer is not for continuous monitoring
of patient gases.
NOTE: There are no user serviceable parts inside
the analyzer. Field calibration of the unit is not re-
quired.
NOTE: When using the analyzer after storage in ei-
ther extremely hot or cold conditions, allow the gas
being measured to flow through the analyzer for one
(1) minute to bring the internal sensor up to the gas
stream temperature.
INSTRUCTIONS FOR USE
(FIGURE 1)
1. Press the ON ( I ) button. The LCD display should
come on.
NOTE:The analyzer automatically shuts off after ap-
proximately two (2) minutes of operation. This helps
save battery life.
2. The display will show "FLO" for approximately two
(2) seconds and then switch to readings in
L/min.
3. If no reading is displayed or if display is erratic or
frozen, refer to the troubleshooting section of this
instruction sheet.
4. In order to measure oxygen concentration or
flow rate, connect the analyzer's FLOW/CON-
CENTRATION inlet with a piece of ¼-inch or
crushproof tubing to the outlet fitting of the gas
source to be measured.
5. In order to measure pressure, connect the
analyzer's PRESSURE inlet with a piece of ¼-
inch or crushproof tubing to the outlet fitting of
the gas source to be measured.

NOTE: The Invacare Check O Plus Hand-Held Ana-
lyzer can be used to measure the performance of an
oxygen concentrator from its outlet fitting, or any con-
centrator accessory such as the Invacare Remote
Flowmeter or Pediatric Flowmeter. However, Invac-
are does NOT recommend using the Invacare Check
O Plus Hand-Held Analyzer to measure flow rates
below 1 L/min. See product specifications.
NOTE: The concentrator output gas, measured from
the concentrator outlet fitting or from a concentrator
accessory outlet fitting,must NOT contain humidified
gas. Disconnect any humidifier bottle before taking
any readings to prevent erroneous readings and dam-
age to the internal flow sensor. Be sure to reconnect
any required humidifier bottle before returning any
equipment to patient use.
