COMPONENT DESCRIPTION

1 OXYGEN CONCENTRATION DIAL — A dial used for selecting oxygen concentrations
between 21%-100%. The FIO2 scale is used for reference only. This Dial does not rotate
360°. The dial starts at 21% and ends at 100%.
2 PRIMARY OUTLET PORT — A male DISS oxygen fitting with check valve that delivers flow
when engaged to any controlling device, such as a flowmeter.
3
AUXILIARY OUTLET PORT — A male DISS oxygen fitting with check valve that deliv-
ers 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: 2–100 l/min (high flow), 0–30 l/min (low flow).
4 AUXILIARY BLEED COLLAR — The collar is used to engage and disengage the bleed. The
bleed is necessary to maintain accurate FIO2 Concentration 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.
5 OXYGEN INLET FITTING — A female DISS or NIST oxygen fitting with one way valve that
is used to connect an oxygen supply hose.
6 AIR INLET FITTING — A male DISS or NIST air fitting with one way valve that is used to
connect an air supply hose.
7 ALARM — An audible alarm that sounds due to an excessive pressure drop or deletion of
either gas supply.

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,
if damaged.
NOTE: The tests listed below should be performed prior to placing the Blender in service.

Pre-Use Testing consists of:
Primary Outlets Flow capacity:
Auxiliary Outlet:
The auxiliary flow outlet maintains the same flow capacity and FIO2 accuracy 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 FIO2 concentration accuracy at the Low Flow
settings.

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
FIO2 range for accuracy with an oxygen analyzer.
High Flow Blender (R203P14 Model) 15 l/min to 120 l/min
•
Low Flow Blender (R203P13 Model) 3 l/min to 30 l/min
•
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.
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.
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,
