7.Confirm the concentration of heliox with an Oxygen Monitor / Analyzer. If necessary activate the bleed flow valve to maintain

FIO2 accuracy.

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

9.To deactivate the bleed, pull and rotate the collar away from the cover until bleed flow valve is closed.

10.Turn “OFF” the heliox and oxygen supply or disconnect when the HELIO2 Blender is not in use.

CLEANING

CAUTION

•DO NOT steam autoclave.

•DO NOT immerse the HELIO2 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.

1.Disconnect all gas connections and equipment before cleaning.

2.Clean exterior surfaces with a cloth dampened with mild detergent and water.

3.Wipe dry with a clean cloth.

Maintenance

The following maintenance on the HELIO2 Blender must be performed by a trained service technician:

•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 506124), and available on the

Internet; www.precisionmedical.com

•Every 2 years the HELIO2 Blender should be serviced.

PM5400 (P/N 506125)

PM5500 (P/N 506212)

•Refer to the HELIO2 Blender Service Manual (P/N 506124) for complete details regarding further maintenance and testing.
