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 R203M15).
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,
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°.
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 FIO2 accuracy.
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.
CLEANING
CAUTION
DO NOT steam autoclave.
DO NOT immerse the Air-Oxygen Blender into any liquid.
DO NOT use any strong solvent or abrasive cleaners.
DO NOT gas sterilize with (EtO) Ethylene Oxide.
DO NOT clean with aromatic hydrocarbons.
DO NOT allow the liquid to penetrate the device.
DO NOT gas or heat sterilize.
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.
4. After all visible contamination is removed; use a second germicidal wipe to
thoroughly wet the surfaces of the device and accessories. Allow to remain wet
for 4 minutes. Use additional wipes if needed to assure surfaces are wetted
continuously for 4 minutes.
5. Allow device to air dry completely.
6. Visually inspect the device for visible contamination. Repeat cleaning/disinfection
process if necessary.

TROUBLESHOOTING
If the Air-Oxygen Blender fails to function, consult the Troubleshooting Guide below. If prob-
lem cannot be solved by using Troubleshooting Guide, refer to the Air-Oxygen Blender Service
Manual (P/N R203M15) available on the Internet; www.maxtec.com or consult your Provider.
PROBLEM
Oxygen
concentration
discrepancy
between
Blender setting
and Analyzer/
Monitor (greater
than 3%)

DISPOSAL INSTRUCTIONS

This device and its packaging contain no hazardous materials. No special precautions need to
be taken when disposing the device and/or its packaging. Please Recycle.
5
The alarm should be tested prior to being placed into clinical service and
•
periodically there after.
Every year conduct the Operational Verification Procedure (OVP).* A detailed
•
description of the OVP tests can be found in the Blender Service Manual (P/N
R203M15), available on the Internet; www.maxtec.com.
Every 2 years the Air-Oxygen Blender should be serviced.
•
Refer to the Air-Oxygen Blender Service Manual (P/N R203M15) for complete
•
details regarding further maintenance and testing.
PROBABLE CAUSE
1. High Flow model, flow
requirement below 15 l/min.
Low Flow model, flow
requirement below 3 l/min.
2. Analyzer/Monitor inaccurate
3. Low flow bleed obstructed
4. Gas supply contaminated
5. Downstream device causing
back flow or restricted flow
1. Gas sources turned "OFF"
2. Gas sources not connected
and air inlet pressures
greater than specified
REMEDY
1. Use auxiliary outlet
& engage bleed
2. Recalibrate Analyzer/
Monitor or Verify with
second Analyzer/Monitor
3. Remove obstruction
4. Check gas sources with
calibrated Oxygen Analyzer/
Monitor to confirm Oxygen
is 100% and Air is 21%
5. Isolate Blender. Check
oxygen concentration
at Blender Outlets
1. Turn gas sources "ON"
2. Connect gas sources
Correct pressure difference
until Air and Oxygen pressures
are within specification
