Pre-use testing

WARNING

•Read this User Manual before installing or operating the HELIO2 Blender.

•Confirm the concentration of heliox with an alarmed Oxygen Monitor /

Analyzer.

•Confirm 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 HELIO2 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 fittings

on the bottom of the HELIO2 Blender.

3.Attach a flowmeter, 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 flow outlet maintains the same flow capacity and FIO2 accuracy as the Primary Outlets with Bleed Valve not engaged. When the bleed flow is activated, some of the heliox mixture will vent to atmosphere to maintain FIO2 concentration accuracy at the low flow 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 flowmeter.

Alarm Test

1.Connect the HELIO2 Blender to respective heliox and oxygen sources, pressurize the Blender and turn “ON” the flowmeter.

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.
