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 (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 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 (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.
