COMPONENT DESCRIPTION
ITEM DESCRIPTION
A
Oxygen Concentration Dial
A dial used for selecting oxygen concentrations between 21%-100%. The FIO2scale is used for
reference only. This Dial does not rotate 360°. The dial starts at 21% and ends at 100%.
B
Primary Outlet Port
A male DISS oxygen fitting with check valve that delivers flow when engaged to any
controlling device, such as a flowmeter.
C
Auxiliary Outlet Port
A male DISS oxygen fitting with check valve that delivers flow when engaged to any
controlling device, such as a flowmeter. This outlet is equipped with a bleed valve that allows
the user to control if the bleed is ON or OFF. With the bleed in the ON position, this outlet
delivers accurate oxygen concentrations in the following flows:
Model Flow Range
High Flow 2 – 100 l/min
Low Flow 0 – 30 l/min
D
Auxiliary Bleed Collar
The collar is used to engage and disengage the bleed. The bleed is necessary to maintain
accurate FIO2Concentration below 15 l/min for the High Flow and
≤3 l/min for the Low Flow. To activate the bleed, slide the knurled collar back until it
contacts the cover. To deactivate the bleed, pull the collar away from cover until it reaches a
positive stop.
E
Oxygen Inlet Fitting
A female DISS or NIST oxygen fitting with one way valve that is used to connect an oxygen
supply hose.
FAir Inlet Fitting
A male DISS or NIST air fitting with one way valve that is used to connect an air supply hose.
G
Alarm
An audible alarm that sounds due to an excessive pressure drop or deletion of either gas
supply.
H Rear Slide Mount with dove tail.

866.4.MAXTEC WWW.MAXTEC.COM4
PRE-USE TESTING
WARNING
•Read this User Manual before installing or operating the Air-Oxygen Blender.
•Confirm the concentration of air/oxygen with an Oxygen Analyzer/Monitor.
CAUTION
Inspect the Air-Oxygen Blender for visual damage before use, DO NOT USE if damaged.
NOTE: The tests listed below should be performed prior to placing the Blender in service.
Pre-Use Testing consists of:
•Alarm Test
•Reverse Gas Flow Procedure
1. Secure the Air-Oxygen Blender to a wall or pole bracket in an upright position.
2. It is recommended to install a condensation trap in the air supply line.
3. Connect the air and oxygen supply lines to the appropriate inlet fittings on the bottom of the
Blender.
4. Attach a flowmeter, or other metering device to one of the outlet ports and verify FIO2range
for accuracy with an oxygen analyzer.
Primary Outlets Flow capacity:
•High Flow Blender (R203P14 Model) 15 l/min to 120 l/min
•Low Flow Blender (
R203P13 Model ) 3 l/min to 30 l/min
Auxiliary Outlet:
The auxiliary flow outlet maintains the same flow capacity and FIO2accuracy as the Primary Outlets
with Bleed Valve not engaged. When bleed flow is activated, some of the air/oxygen mixture will vent
to atmosphere to maintain FIO2concentration accuracy at the Low Flow settings.
•High Flow Blender (R203P14 Model) 15 l/min or less
•Low Flow Blender (R203P13 Model) 3 l/min or less
5. Attach a supply line to the outlet port of the flowmeter.
ALARM TEST
1. Connect the Air-Oxygen Blender to air and oxygen sources, pressurize the Blender and turn
“ON” the flowmeter.
2. Set Oxygen Concentration Dial to 60% FIO2.
3. Disconnect or turn “OFF” the air supply to the Air-Oxygen Blender. The Blender should alarm
with a loud whistle noise. The whistle indicates the alarm is operating correctly.
4. Reconnect and activate the air supply line to the Blender, the alarm should stop whistling.

866.4.MAXTEC WWW.MAXTEC.COM5
5. Disconnect or turn “OFF” the oxygen supply line to the Blender. The whistle indicates the
alarm is operating correctly.
6. Reconnect and activate the oxygen supply line to the Blender, the alarm should stop whistling.
7. If alarm fails to function properly, DO NOT USE.
REVERSE GAS FLOW PROCEDURE
1. Disconnect the oxygen hose from the gas source. Remove all outlet connections from the
Blender to ensure that there is no outlet flow.
2. While gradually increasing the air supply pressure from 30-75 psi (2.07-5.17 bar) check for
leakage past the oxygen inlet check valve.
3. Replace the Duckbill Check Valve in the oxygen inlet if leakage is > 100 ml/min. Reference Air-
Oxygen Blender Service Manual (P/N R203M10).
4. Repeat steps 1-3 to check for leakage past the air inlet check valve.
OPERATING INSTRUCTIONS
CAUTION
Inspect the Air-Oxygen Blender for visual damage before use, DO NOT USE if damaged.
1. Secure Blender to wall or pole mount bracket.
2. Connect Air and Oxygen supply lines from Blender to wall outlets.
3. Connect flowmeter to Blender outlet.
4. Adjust the Oxygen Concentration Dial to the prescribed concentration.
NOTE: The Oxygen Concentration Dial does not rotate 360°. DO NOT force dial less than 21% or
over 100% oxygen, this will damage the Blender.
5. Confirm the flow of air and/or oxygen mixture to the patient.
6. Confirm the concentration of air/oxygen with an Oxygen Analyzer/Monitor. If necessary
activate bleed flow valve to maintain FIO2accuracy.
7. To activate the bleed, slide the knurled collar back until it contacts the cover.
8. To deactivate the bleed, pull the collar away from the cover until bleed flow valve is closed.
9. Turn “OFF” gas supplies when Air-Oxygen Blender is not in use.

866.4.MAXTEC WWW.MAXTEC.COM6

1. Disconnect all gas connections and equipment before cleaning.
2. Close Bleed Valve to ensure O-Ring is not exposed.
3. Clean exterior surfaces using Super Sani-Cloth germicidal disposable wipes. Remove all visible
contamination from the external surfaces of the device and its accessories. Be sure to closely
inspect and remove contamination from seams and recesses on the device that may trap
contaminants. Wipe with clean paper towel to remove debris.

necessary.
MAINTENANCE
The following maintenance on the Air-Oxygen Blender must be performed by a trained service
technician:

Le mélangeur air-oxygène a été dégraissé pour service d’oxygène avant la livraison.
Le débit de gaz inverse du mélangeur air-oxygène est conforme à l’alinéa 6 de la norme ISO 11195.
L’analyseur d’oxygène doit être conforme à la norme ISO 21647 pour répondre aux impératifs CE.
SÉCHERESSE ET COMPOSITION POUR LES GAZ D’ENTRÉE:
Air: L’alimentation en air de qualité médicale doit satisfaire aux exigences
de la norme ANSI Z86.1-1973 de spécification de produit pour l’air,
type 1 qualité D ou meilleure.
Oxygène: L’alimentation en oxygène doit satisfaire aux exigences de l’oxygène
de qualité médicale USP qualité N.
Point de
rosée:
Les deux entrées doivent rester 5,55 °C (10 °F) ou plus en dessous
de la température la plus basse à laquelle est exposé l’équipement du
système de distribution de l’air. À une température de -3,9 °C (25 °F)
et une pression de 90 psi (6,33 kg/cm2) cela équivaut à 2 000 mg/
m3.
* La précision de la concentration en oxygène est faussée si la purge n’est pas activée pour des réglages de débit
inférieurs à 15 L/min pour le mélangeur à débit élevé et 3 L/min pour le mélangeur à faible débit.
