|
|
|
| enabled. Refer to the Setup Overlay descrip- |

|
| 2. If the water cooler is enabled but there is |

|
|

|
|

|
|
|
|
| water cooler. Refer to the Setup Overlay |

|
| on the machine. In this case do the following: |
|
|
|
|
| 1. Turn the machine off and on a couple of |
|
|
|
|
| times and see if the beeping continues. If the |
|
|
|
|
| pressure dropped momentarily then turning |
|
|
|
|
| the machine off and on eliminates the beep- |
|
|
|
|
| ing. A momentary pressure drop could be due |
|
|
|
|
| to someone stepping on the water cooler |
|
|
|
|
| hose, for example. |
|
|
|
|
| 2 Check the water cooler hose for kinks and |
|
|
|
|
| other places of reduced water flow. If such |
|
|
|
|
| problems were found then correct them and |
|
|
|
|
| turn the machine off and on to check if the |
|
|
|
|
| beeping has been eliminated. |
|
|
|
|
| 3. Check the water cooler fluid level. Low fluid |
|
|
|
|
| level could cause the pressure to drop. |
|
|
|
|
| 4. Prime the water cooler. Refer to the Setup |
|
|
|
|
| Overlay section of this manual for instructions. |
