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.

866.4.Maxtec www.maxtec.com

• 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.
