WARNINGS

• Use flowmeters only for their “Intended Use” as described in this manual.
• This product should only be used under supervision from a healthcare professional
• If you do not understand this manual, **** DO NOT USE the flowmeter and contact your provider.
• ALWAYS confirm prescribed flow before administering to patient and monitor flow on a frequent basis.
• Not compatible with MRI systems .
• Read this user manual before installing or operating the flowmeter.
• Maxtec assumes no responsibility for any damage or injury caused by improper installation, assembly, or use of this product.

To Reduce the Risk of Fire or Explosion:

◆ ALWAYS follow ISO, 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 lubricants other than those recommended by the manufacturer.
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 disassemble the flowmeter or remove connectors while under pressure.
DO NOT smoke in an area where oxygen is being administered.

CAUTION

• Use caution to avoid cross-threading fittings during installation
• Always use a backing wrench when installing or removing connectors.
• 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 drop the flowmeter.
DO NOT autoclave.
DO NOT use substitute parts. If components are damaged or missing, contact your dealer immediately.
DO NOT gas sterilize with EtO (Ethylene Oxide).
DO NOT permit any cleaning solution to enter into the manifold or the flowmeter(s).
DO NOT clean with aromatic hydrocarbons.
DO NOT immerse flowmeter in any kind of liquid. This will void the warranty.
DO NOT USE if damaged. Inspect the flowmeter for visual damage before use.
DO NOT over-tighten knob when turning off. This will cause damage to the flowmeter.
DO NOT over-tighten any threaded connectors; body may crack and cause leaks.

• Inlet 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  lowmeters.

PRODUCT OVERVIEW

1.1 Description
The flowmeter is designed to accurately adjust and dispense a known flow rate of medical oxygen or air. 1.1 Description

The Flowmeter Manifold with built-in IV Pole Mount is designed to receive an inlet gas and to deliver that gas to either one or two flowmeters mounted to the manifold. It has standard gas-specific fittings such as DISS or NIST in order to receive gas from a wall or cylinder source. The Manifold also incorporates a common pole clamp designed to permit a user to mount the Manifold directly to an IV Pole.

1.2 Intended Use
Flowmeters are intended for use by physicians, respiratory therapists and other authorized hospital personnel to administer selected doses of medical oxygen or air to a patient
The Flowmeter Manifold is intended for use where a flow of metered gas is required and to allow the gas to be delivered through one or two flowmeters that are connected to a standard IV Pole up to 1.5″ outer diameter.

SPECIFICATIONS

2.1 General Specifications.

Gas Inlet …………………………………………………………….. Regionally Standardized Gas Specific Fitting
Max Pressure ……………………………………………………………………………………………………………….100 psi
Manifold Application (when included) ……………………………………Fits poles up to 1.5″ in diameter

2.2 Flow Range Accuracy

±14 cc/min for range 101-200 cc/min
0-1 L/min| ±0.05 L/min
0-3.5 L/min| ±0.15 L/min
0-5 L/min| ±0.20 L/min
All flowmeters with maximum flow greater than 5 L/min| ±0.50 L/min for range 0-5 L/min
±10% of indicated flow for range >5 L/min

The above accuracy is guaranteed when the gas inlet pressure and gas type are the same as those indicated on the flowmeter body. Inlet pressures and gases other than those indicated may affect the accuracy of the indicated flow.
The flowmeter is calibrated at the inlet pressure specified on the flowmeter body, 70°F (21°C), and standard atmospheric pressure. Specifications are subject to change without prior notice.

2.3 Maximum Flush Flow
Any flow beyond the last calibrated line on the Flow Tube with unrestricted flow is Flood/ Flush flow. The maximum flow (flood/flush flow) is indicated in the table below.

Acrylic Block Style
0-70 L/min| 70-90 L/min for Thorpe Tube Style 203 L/min for Acrylic Block Style
0-80 L/min| 203 L/min

The above flush flows are based on 50 psi inlet pressure , 70˚F (21˚C), at standard atmospheric pressure. Specifications are subject to change without prior notice.

2.4 Transport/Storage Requirements -40 °F (-40 °C) to 140 °F (60 °C)

NOTE: Storage/transport outside the specified range may cause damage to the flowmeter.

OPERATING INSTRUCTIONS

NOTE: Maxtec strongly recommends the use of kink proof cannula.

3.1 Flowmeter Manifold Instructions

1. Mount the device vertically and upright on a pole using the pole clamp and hand-screw.
2. Tighten the hand-screw to ensure the device is secure on the pole.
3. Attach an appropriate inlet gas source to the gas inlet on the manifold.
4. Adjust the flow using the flowmeter’s flow control valve. Reference the instructions below for complete details associated with use of the flowmeter(s).

3.2 Flowmeter Instructions

1. Turn knob to the “OFF” position.

2. Connect the flowmeter vertically to the appropriate gas source. The appropriate gas and pressure are specified on the flowmeter 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 may be 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.

TROUBLESHOOTING

4.1 Troubleshooting Table
If the flowmeter fails to function, consult your provider or Maxtec.

RECOMMENDED MAINTENANCE

5.1 Cleaning Instructions

Use caution when cleaning – do not permit any cleaning solution to enter into the manifold or flowmeter(s).

1. Depressurize and disconnect all connections before cleaning.
2. Clean exterior surfaces of the flowmeter and manifold with a cloth dampened with a mild detergent and water.
3. Wipe dry with a clean cloth.

CAUTION: ****DO NOT Autoclave.
