For the best results, make sure that the cutting system is prepared to operate and the gases are flowing
when you select the gas regulator settings. This is almost equivalent to doing a test for gas preflow and
cutflow.
2. Optional: Connect the shield water, if necessary.
□
If you use shield water, refer to Shield-water requirements (VWI and OptiMix) on page 55.
□
The temperature range for cutting system operation with shield water is decreased to > 0°C to
40°C (> 32°F to 104°F).
3. After installation is complete, fully pressurize the system, and look for gas leaks.
Your system installer or a licensed plumber can do this for you.
