|  |           |       |    motherboard, call Veritas support to replace the  |
|  |           |       |    fan.                                              |

|  |           |       |    call Veritas support to replace the failed fan.   |
|4 |Fan        |Warning|    Once replaced, the speed will stay within water   |

|  |           |       |    temperature table. If the temperature of appliance|
|  |           |       |    rises, then fan speed increases unless proper     |
|  |           |       |    cooling is provided to the machine.               |
