Filling the Cooling System
WARNING: Do not touch the fans inside the cooling system.
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 cover from the
cooling system.
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 MGC.
9. On the MGC main menu, move the pointer to On. Press the select
button to start
the coolant pump circulating coolant through the system. Note: 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.
10. With the coolant pump running, locate the small red push-button on top of the
coolant filter housing. Press and hold the red button until no air or bubbles are seen
inside the filter housing. Dry any coolant that leaks out.
11. Check for coolant leaks at all hose connections, the arc starting console, and at the
torch.
12. Push the OFF Button on the MGC to stop the coolant pump.
13. Remove primary power from the Spirit system.
14. Fill the reservoir with coolant until the coolant gauge indicates full.
