The Air-Oxygen Blender has been degreased for Oxygen Service prior to delivery.
The Air-Oxygen Blender reverse gas flow complies with clause 6 of ISO 11195.
The Oxygen Analyzer should comply with ISO 7767 to meet CE requirement.
Dryness and Composition for inlet gases:
Air:
Medical Air supply should meet the requirements of
ANSI Z86.1 - 1973 commodity specification for Air, type
1 grade D or better.
Oxygen:
Oxygen supply must meet all requirements of USP
Medical Oxygen Grade N.
Dew Point:
(ONLY for CE
requirements)
Both inlets should remain 10°F (5.5°C) or more
below the lowest temperature to which the air
distribution system equipment is exposed. At a
temperature of 25°F (-3.9°C) and a pressure of
90 psi (6.33 kg/cm2) this equates to 2000 mg/m3.
* Accuracy of oxygen concentration will be affected if bleed is not activated at flow settings below 15 lpm for the high flow
Blender, and 3 lpm for the low flow Blender.
Specifications are subject to change without prior notice.

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 lpm
Low Flow 0 – 30 lpm
D Auxiliary Bleed Collar
The collar is used to engage and disengage the bleed.
The bleed is necessary to maintain accurate FiO 2
Concentration below 15 lpm for the High Flow and 3
lpm for the Low Flow. This collar is designed to prevent
accidental disengagement of the bleed. To activate
the bleed, turn the knurled collar until the bleed pin is
engaged. Slide collar back until it contacts the cover.
To deactivate the bleed, pull collar away from cover
while rotating until the collar slot engages the pin, turn
additional 1/4 turn to lock in place.
E Oxygen Inlet Fitting
A female DISS or NIST oxygen fitting with one way valve
that is used to connect an oxygen supply hose.

G Alarm
An audible alarm that sounds due to an excessive
pressure drop or deletion of either gas supply.
H Manifold Outlet (Optional)
Manifold with 3 primary outlets.
I Rear Slide Mount with dove tail.
INSTALLATION
WARNING
Read this User Manual before installing or operating the
Air-Oxygen Blender.
Confirm the concentration of air/oxygen with an Oxygen
Analyzer/Monitor.
•
•
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.
Primary Outlets Flow capacity:
• High Flow Blender (PM 5200 Model) 15 lpm to 120 lpm
• Low Flow Blender (PM 5300 Model) 3 lpm to 30 lpm
Auxiliary Outlet:
This will bleed off some of the air/oxygen mixture to
maintain concentration accuracy at the Low Flow setting.
• High Flow Blender (PM 5200 Model) 15 lpm or less
• Low Flow Blender (PM 5300 Model) 3 lpm or less
5. Attach a supply line to the outlet port of the flowmeter.

Air-Oxygen
ALARM TEST
1. The Air-Oxygen Blender is installed and the flowmeter is turned
on. Disconnect or turn off the air supply line to the Air-Oxygen
Blender.
2. The Blender should alarm with a loud whistle noise. The whistle
indicates the alarm is operating correctly.
3. Reconnect and activate the air supply line to the Blender, the
alarm should stop whistling.
4. Disconnect or turn off the oxygen supply line to the Blender.
5. The Blender should alarm with a loud whistle noise. 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
(CE Requirements ONLY)
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. Place the free end of the oxygen supply hose under water. 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
bubbles indicate leakage. Reference Air-Oxygen Blender
Service Manual (P/N 504827.)
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. Turn “ON” the Air and Oxygen supply.
2. 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.

Blender
Air-Oxygen
3. To activate the bleed, turn the knurled collar until the bleed
pin is engaged. Then slide the collar back until it contacts the
cover.
4. Confirm the concentration of air/oxygen with an Oxygen
Analyzer/Monitor.
5. Confirm the flow of air and/or oxygen mixture to the patient.
6. Turn “OFF” the Air and Oxygen supply when deactivating the
Auxiliary bleed, and no device is attached to the outlet port.
7. To deactivate the bleed, pull the collar out away from the cover
while rotating the collar until the slot engages the pin. Then
slide the collar past the pin and turn an additional 1/4turn to
lock in place.
NOTE: This Procedure is completed with ease when all gas
supplies to the Blender are turned “OFF”.
8. Turn “OFF” the Air and Oxygen supply or disconnect when
the Blender is not in use.
9. Operational Verification listed below should be done before
the Blender is placed in service.
Verification consists of:
• Alarm Test
