Filling the Cooling System
WARNING: Do not touch the fans inside the power supply.
Important: Never turn on the system when the coolant reservoir is empty.
Important: When handling coolant, wear nitrile gloves and safety glasses.
Important: Only use approved coolant. Commercially available antifreeze
contains corrosion inhibitors that will damage the cooling system.
See Section 2 for more information.
1. Remove primary power from the Spirit system.
2. Ensure the torch base and torch head (with consumables) are properly installed.
3. Ensure the coolant supply (in and out) hoses are properly installed.
4. Remove the coolant reservoir cap/level gauge and then remove the top, left and
right covers from the power supply.
5. Ensure the coolant filter housing is tightened securely.
6. Ensure the drain petcock on the bottom of the reservoir is tightened securely.
7. Fill the reservoir with approximately 2 ½ gallons of approved coolant.
8. Apply primary power to the Spirit system and enable it by releasing (turn right) the
OFF Button on the plasma console.
9. On the plasma console, press the Diagnostics navigation button to access the
Pressures/Coolant tab.
10. Press the Fill/Flush button to start the coolant pump circulating coolant through the
system. Note: the Coolant Flow indicator (press the Status navigation button) will
remain red until the coolant has filled the entire system and begins flowing back into
the tank. The coolant pump will turn off automatically if the coolant level drops
below the minimum level inside the reservoir. If this happens, add more coolant. If
the Fill/Flush button is not available (grayed out), release (turn right) the OFF Button.
11. With the coolant pump running, locate the small red push-button on top of the
coolant filter housing (beneath the reservoir). Press and hold the red button until no
air or bubbles are seen inside the filter housing. Dry any coolant that leaks out.
12. Check for coolant leaks at all hose connections, the arc starting console, and at the
torch.
13. Once the flow rate has stabilized (see Diagnostics > Pressures/Coolant tab), press
the Fill/Flush button again to stop the coolant pump.
14. Remove primary power from the Spirit system.
15. Fill the reservoir with coolant until the coolant gauge indicates full.
16. Replace the power supply covers and replace the coolant reservoir cap/level gauge.
17. End of procedure.
