WARNING
-
Use Flowmeters 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.
-
Flowmeters may contain magnetic, ferrous material that may affect the results of an MRI.
To Reduce the Risk of Fire or Explosion: -
ALWAYS follow ANSI and CGA standards for Medical Gas Products and Flowmeters and Oxygen Handling.
-
DO NOT use or store oils, greases, organic lubricants or any combustible materials on or near this Flowmeter.
-
DO NOT use near any type of flame or flammable/explosive substances, vapors or atmosphere.
-
DO NOT smoke in an area where oxygen is being administered.
CAUTION
- Flowmeters must be operated with the Flow Tube in a vertical, upright position.
- Only personnel instructed and trained in its use should operate this Flowmeter.
- Ensure all connections are tight and leak free.
- Only use oxygen-safe leak detector.
- DO NOT autoclave.
- DO NOT gas sterilize with EtO (Ethylene Oxide).
- DO NOT clean with aromatic hydrocarbons.
- DO NOT immerse Flowmeter in any kind of liquid. This will void the warranty.
- The 1MFA3001, 4MFA1001 & 6MFA1001 Flowmeters may have a factory installed restrictor. Prior to use, check Flowmeter labeling for flow restrictions.
- The 1MFA3001, 4MFA1001 & 6MFA1001 Flowmeters contain a glass Flow Tube which is fragile. Special care should be observed to avoid breaking the Flow Tube.

Flush Flow is the output of the flowmeter when the flow indicator is beyond
the highest calibrated graduation. The Flush Flow range is as indicated on the
flowmeter labeling.
Transport / Storage Requirements
-40˚F (-40˚C) to 140˚F (60˚C) The gas and inlet pressures are indicated on the Flow Tube or Flowmeter body.
NOTE: Storage / Transport outside the specified range may cause damage to
the flowmeter.
The effect on accuracy of flow due to variations in ambient temperature is
standard accuracy +7.3% @ 32°F (0°C) and -3.0% @ 104°F (40°C).
The above Flowmeter models are calibrated at specified inlet pressure, 70°F
(21°C), standard atmospheric pressure. International models are calibrated per
specifications marked on Flow Tube or Flowmeter body.
Specifications are subject to change without prior notice.
CAUTION
- DO NOT over tighten Knob when turning off. This will cause damage to the Flowmeter.
- Pressures other than those indicated on the Flow Tube or Flowmeter body may affect the accuracy of the indicated flow.
- Gas Temperatures other than 70° F (21°C) may affect 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 affect the accuracy of the flow.
- ONLY use appropriate gas specific indexed fittings to connect Flowmeter to gas source. Use Oxygen connections for oxygen Flowmeters; use air connections for air Flowmeters.
- DO NOT attempt to repair the 8MFA Flowmeters. There are no serviceable parts.
CLEANING INSTRUCTIONS
- Disconnect all connections before cleaning.
- Clean exterior surfaces of the Flowmeter with a cloth dampened with a mild detergent and water.
- Wipe dry with a clean cloth.

Adjusting flow beyond the last calibrated indicator line will result in an undetermined flow.
-
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 flowmeter labeling.
