1.0 PRODUCT OVERVIEW
1.1 Description
The flow meter is intended for use by physicians, respiratory therapists
and other authorized hospital personnal to administer selected doses of
medical gases to a patient.
1.2 Indications for use
This manual instructs a professional to install and operate the flow meter.
This is provided for your safety and to prevent damage to the flow meter.
If you do not understand this manual, DO NOT USE the flow meter and
contact your provider.
1.3 Warnings
• Use flow meters only for their “Intended Use” as described in this
manual.
• ALWAYS confirm prescribed flow before administering to patient and
monitor flow on a frequent basis.
• Flow meters may contain magnetic, ferrous material that may aect
the results of an MRI.
• Read this User Manual before installing or operating the flow meter.
To Reduce the Risk of Fire or Explosion:
• ALWAYS follow ANSI and CGA standards for Medical Gas Products
and flow meters and Oxygen Handling.
• DO NOT use or store oils, greases, organic lubricants or any
combustible materials on or near this Flow meter.
• DO NOT use near any type of flame or flammable/explosive
substances, vapors or atmosphere.
• DO NOT connect to source pressure greater than 100 psi.
• DO NOT smoke in an area where oxygen is being administered.
1.4 Cautions
• Use caution to avoid cross-threading fittings during installation.
• Always use a backing wrench when installing or removing connectors.

• Flow meters must be operated with the Flow Tube in a vertical,
upright position.
• Only personnel instructed and trained in its use should operate this
flow meter.
• Ensure all connections are tight and leak free.
• Only use oxygen-safe leak detector.
• Only trained medical professionals should operate the flow meter.
• DO NOT drop the flow meter.
• DO NOT autoclave.
• DO NOT gas sterilize with EtO (Ethylene Oxide).
• DO NOT clean with aromatic hydrocarbons.
• DO NOT immerse flow meter in any kind of liquid. This will void the
warranty.
• DO NOT USE if damaged. Inspect the flow meter for visual damage
before use.
• DO NOT over-tighten knob when turning o. This will cause damage
to the flow meter.
• DO NOT over-tighten any threaded connectors; body may crack and
cause leaks.
• Pressures other than those indicated on the flow tube or flow meter
body may aect the accuracy of the indicated flow.
• Gas Temperatures other than 70° F (21°C) may aect the accuracy of
the indicated flow.
• Attaching accessories to the outlet (which may increase resistance
to outlet flow) may change indicated flow but will not aect the
accuracy of the flow.
• ONLY use appropriate gas specific indexed fittings to connect flow
meter to gas source. Use Oxygen connections for oxygen flow
meters; use air connections for air flow meters.

Flush Flow is the output of the flow meter when the flow indicator is
beyond the highest calibrated graduation. The Flush Flow range is as
indicated on the flow meter labeling.
2.2 Transport/Storage Requirements
-40 °F (-40 °C) to 140 °F (60 °C)
The gas and inlet pressures are indicated on the flow tube or flow
meter body.
NOTE: Storage/transport outside the specified range may cause damage
to the flow meter.
The above flow meter models are calibrated at specified inlet pressure,
70°F (21°C), standard atmospheric pressure. Specifications are subject to
change without prior notice.

3.0 OPERATING INSTRUCTIONS
3.1 General Operation
NOTE: Maxtec strongly recommends the use of kink proof cannula.
1. Turn knob to the “OFF” position.
2. Connect the flow meter vertically to the appropriate gas source. The
appropriate gas and pressure are specified on the flow meter body.
3. Verify that the float ball is at the very bottom of the flow tube.
NOTE: If the float is not resting at the bottom of the flow tube, the
product is leaking; consult the “TROUBLESHOOTING” Section 4.0.
4. Adjust flow:
To increase- Turn knob counterclockwise
To decrease- Turn knob clockwise
5. Set flow by aligning center of float ball with indicator lines on the
flow tube.
6. Adjusting flow beyond the last calibrated indicator line will result in
an undetermined flow.
7. To obtain maximum flush flow, turn knob fully counterclockwise.
NOTE: Flush flow is any flow above the last calibrated line on the flow
tube with an unrestricted flow, as indicated on flow meter labeling.
