Installing Airwallet Harness

1. Power down the machine by unplugging or turning of the breaker.

2. Open the front control panel by removing the two (2) top retaining screws.

5. Feed the Airwallet harness through the vault access hole on the right side of the control cavity.

6. Open the vault cover and pull the harness though.

the Airwallet harness.

10. Plug the Busy signal feed back harness into the control board at H5 if using the busy signal from machine.

11. Reassemble the vault pocket by reinstalling the control. Take care not to snag or pinch any wire harnesses and make sure the harnesses are out to the way of operation of the coin slide switch. Close and lock the vault.
