HELIO2
BLENDEr
HELIUM-OXYGEN
PRE-USE TESTING
WARNING
• Read this User Manual before installing or operating the
HELIO2
Blender.
• Conrm the concentration of heliox with an alarmed Oxygen Monitor /
Analyzer.
• Conrm contents of heliox cylinder prior to use.
CAUTION
Inspect the HELIO2 Blender for visual damage before use, DO NOT
USE if damaged.
NOTE: The tests listed below should be performed prior to placing the
H
ELIO2 Blender in service.
Pre-Use Testing consists of:
•Alarm Test • Reverse Gas Flow Procedure
1.
Secure the
HELIO2 Blender
to a wall or pole bracket in an upright position.
2. Connect the heliox and oxygen supply lines to the appropriate inlet ttings
on the bottom of the HELIO2 Blender.
3.
Attach a owmeter, or other metering device to one of the outlet ports and
verify
FIO2
range for accuracy with an alarmed Oxygen Monitor / Analyzer.
Primary Outlets Flow capacity:
• High Flow Blender (PM 5500 Model) 15 lpm to 120 lpm
• Low Flow Blender (PM 5400 Model) 3 lpm to 30 lpm
Auxiliary Outlet Use:
The auxiliary ow outlet maintains the same ow capacity and
FIO2
accuracy
as the Primary Outlets with Bleed Valve not engaged. When the bleed ow is
activated, some of the heliox mixture will vent to atmosphere to maintain
FIO2
concentration accuracy at the low ow settings.
•High Flow Blender (PM 5500 Model) 15 lpm or less
• Low Flow Blender (PM 5400 Model) 3 lpm or less
4. Attach a supply line to the outlet port of the owmeter.
ALARM TEST
1. Connect
the
HELIO2
Blender to respective heliox and oxygen sources,
pressurize the Blender and turn “ON” the owmeter.
2. Set Oxygen Concentration Dial to 50% FIO2.
3. Disconnect or turn “OFF” the heliox supply line to the HELIO2 Blender. The
Blender should alarm with a loud whistle noise. The whistle indicates the
alarm is operating correctly.
4. Reconnect and activate the heliox supply line to the Blender, the alarm
should stop whistling.
5. Disconnect or turn “OFF” the oxygen supply line to the HELIO2 Blender.
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.
