
Connect the hoses from the pressure regulators on the gas bottles to the gas console.
Make sure that explosion protectors are mounted on the regulators connected to
flammable gas and oxygen. Check that the installation is in accordance with
national/regional laws and regulations. Make sure that the different gases are
connected to the right input on the GCU.

If necessary, fill up with coolant. Only use pure mono-ethylene as anti freeze agent
and de-ionised or distilled water. Any other coolant may be electrically conductive
which leads to ignition problems. The original coolant consists of 30% glycol and
70% distilled water which gives freeze protection down to -5°C.

Connect the the power source to the CNC-control system or robot via the 25-pole
contact marked CNC on the rear of the power source. Be very careful to follow the
instruction in the diagram as a faulty connection can lead to disturbance in the
function of the plasma system.

Make sure that all system components and hose assembly screens are grounded
together and that all doors and panels are closed.

Connect gas and make sure that all hoses and connections are tight. Be extra careful
with flammable gases and oxygen. Remember that a gas leak can lead to fire or
explosion with injury to person and property.

Connect the return lead to the front panel of the power source and attach the clamp
directly to the work piece.

The machine is now ready to be connected to electricity and startup.

It can take up to 2-3 minutes before all hoses are filled with coolant when starting the
machine for the first time. Avoid cutting during this time. Remember that the hoses
can take up to 25% of the coolant volume, refill the tank with coolant.
