Do not stand in front of a flowmeter or regulator outlet when opening a cylinder
valve.
Do not allow any fluid to enter this device.
The accuracy of the flowmeter can be affected significantly if the input pressure is
other than stated in the technical specification and the device label.
Do not directly connect the flowmeter output to another pressurised gas source as
this may lead to corruption of one or other of the gas supplies (e.g. connecting an
oxygen flowmeter to an air flowmeter via a Y-piece in an attempt to blend their
outputs).
Only use this flowmeter with the flow tube in a vertical position. Failure to do so
may result in incorrect flow rates being displayed.
Make sure that the flow control valve is not clogged or obstructed and that there
is no unwanted pressure. In such cases, there may be temporary changes in the gas
flow.
Arrange the oxygen tubing and gas hose carefully to avoid damage to the hose and
the potential for causing a trip hazard. Never pull or apply excessive force to the
gas hose. A leaking hose may result in high local oxygen and nitrous oxide
concentrations and an increased risk of fire.
Oxygen is not flammable; however the presence of it will drastically increase the rate and
severity of combustion. Oil and/or grease in the presence of an oxygen enriched
atmosphere will become highly combustible. Oxygen must never be allowed to come into
contact with oil, grease or other petroleum-based substances.
Do not use oil or grease on this flowmeter
Do not smoke around oxygen equipment
NOT suitable for sterilization / autoclaving
DO NOT use if there is contamination
DO NOT clean with aromatic hydrocarbons
Caution:
The flowmeter performance may be affected if it is stored or transported at temperatures
outside the range of -20 ° C to +50 ° C.
The performance of the flowmeter may be affected if the flow control valve is over-
tightened when the flow is turned off. Apply the minimum force required to turn off the
gas flow.
