Spirit II User's Manual
Section 6: Maintenance & Troubleshooting
WARNING: Only qualified maintenance personnel should perform
maintenance on the Spirit system.
The system utilizes potentially fatal A.C. and D.C. voltages. All maintenance
should be performed with safety in mind.
Use extreme caution when working near the power conversion module (i.e.,
chopper). The large electrolytic capacitors store large amounts of energy
even after power has been removed from the system. Wait at least five
minutes after turning off power, and then use a voltmeter to verify that the
capacitors are fully discharged before touching the power conversion module.
Capacitor failure can injure and/or cause property damage.
If troubleshooting requires the system to be powered with the enclosure
panels removed, remain clear of the capacitors. Failure of a capacitor can
result in a sudden release of stored energy causing rupture of the capacitor
case.

Routine Maintenance

Note: At minimum, these checks should be performed on a monthly basis. In
excessively dirty environments or in heavy usage situations, the checks
should be performed more frequently.
Power Supply
1. Remove the left, right, and top covers on the power supply.
2. Using clean, dry, compressed air, blow out all accumulated dust, including dust on
PC boards and fans. Be sure to blow out the fan and heat exchanger at the rear of
the unit. In an excessively dirty environment, blow out the unit on a weekly basis.
3. Verify the ground and primary three phase A.C. voltage connections are tight.
4. Verify all PC board connectors are installed securely.
5. Verify all rear cable connectors are installed securely.
6. Verify the electrode lead and work ground lead are secure and free from corrosion.
7. Check the torch coolant filter / deionization cartridge at the rear of the power supply
and replace if dirty.
8. Flush the cooling system every six months and replace the coolant and coolant filter
/ deionization cartridge.
