DIAGRAMS

CAUTION
Missing or illegible labels must be replaced, contact Precision Medical, Inc.

Depending on model, your fittings and/or labels may differ from these diagrams

COMPONENT DESCRIPTION

A dial used for selecting oxygen concentrations between 21%-100%. The FIO 2 scale 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 FIO 2 Concentration below

15 l/min for the High Flow and ≤ 3 l/min for the Low Flow. To activate the bleed, slide and rotate (if applicable) the knurled collar back until it contacts the cover. To deactivate the bleed, pull and rotate (if applicable) 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.

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| Manifold Outlet (Optional) Manifold with 3 primary outlets.
I| Rear Slide Mount with dove tail.

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 FIO2 range for accuracy with an oxygen analyzer.
   Primary Outlets Flow capacity:

   • High Flow Blender (PM 5200 Model) 15 l/min to 120 l/min

   • Low Flow Blender (PM 5300 Model) 3 l/min to 30 l/min
     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.

   • High Flow Blender (PM 5200 Model) 15 l/min or less

   • Low Flow Blender (PM 5300 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.
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 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. 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 FIO2 accuracy.

7. To activate the bleed, turn and rotate the knurled collar back until it contacts the cover.

8. To deactivate the bleed, pull and rotate 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.
