Function
- Safe connection to oxygen and acetylene Integra® cylinders
- Provide protection against: Reverse flow of gas; Flashbacks and Burnbacks
Only use
- Product marked "A" with Integra® acetylene cylinders. Maximum pressure 1.5 bar
- Product marked "O" with Integra® oxygen cylinders, pressure 10 bar maximum 15 bar.
Warning – Danger to Life if equipment not used in accordance with instructions
- Use only with the type of gas indicated on the flash back arrestor
- Use only for gas flow in the direction indicated on the flash back arrestor
- Do not exceed the maximum operating pressure indicated on the flash back arrestor
- Use only with Integra cylinders. Do not connect to any other cylinder type, pressure vessel or gas delivery system
- Repairs must only be carried out by the manufacturer or its approved agents.
- Do not connect more than one operational unit (e.g. cutting torch)
- Additional marking, engraving or stamping on the flash back arrestor is strictly forbidden
Instructions for use:
- Before assembling the gas delivery system ensure that all connections are clean, free from grease and oil and undamaged.
- Do not use any lubricants, sealants, pastes or tapes when assembling the gas delivery system.
- Ensure gas-tight connection between the flashback arrestor and hose by use of two open-ended spanners, as shown below.
- When gas delivery system has been assembled, pressurise the system to the maximum working pressure and test for leaks using an approved leak detection method.
- Hose connectors must comply with EN 560.
- Hoses must comply with EN 559.
- Hose glands must comply with EN 1256.
- During periods of extended inactivity or at end of the working day and prior to the coupling being disconnected, the gas source should be closed using the on / off hand wheel on the valve.
- Couplings should not be exposed to bending forces.
Maintenance:
- The gas delivery system must be tested in accordance with national statutory requirements.
- It is recommended that the Flashback arrestor is tested for leaks and gas returnflow safety at least once per year.
Fault-finding:
- No flow: Check the direction of flow, working pressure, cylinder on/off valve, cylinder capacity (full/empty). If unit prevents flow - replace the unit.
- Leak: Check gas-tight connects. If unit damaged - replace the unit.
