 Only appropriately trained personnel working in controlled conditions may disassemble or
assemble this flowmeter.
 Do not disassemble the flowmeter whilst under pressure.
 Secure cylinders to a wall, stand or cart in accordance with local safety regulations.
 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.
 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.
 Gas flow may be prevented if the supply tubing is kinked or occluded.
 Care should be taken to ensure that the flow control valve is free from obstruction and unintended
pressure. These scenarios may result in temporary changes in flow.
2.2. Cautions!
 The performance of the flowmeter may be affected if it is stored or transported in temperatures
outside of the range -20 °C to 60 °C (-4 °F to 140 °F).
 The flowmeter is not suitable for autoclaving.
 Where a threaded fastener is used, do not use the device to tighten or lock connection.
 The performance of the flowmeter may be affected if the flow control valve is over-tightened when
switching off flow. Apply the minimum force required to switch off gas flow.
