| The water cooler does not turn on. | 1. Make sure that the water cooler has been |
|
|
| enabled. Refer to the Setup Overlay descrip- |

|
|
|
| |
|
| tion in the Operation Section of this manual. |
|
|
|
| 2. The cooler’s circuit breaker may have tripped. |
|
|
|
| 3. If the water cooler is enabled but generates |
|
|
|
| insufficient coolant pressure, the machine will |
|
|
|
| beep loudly and the water cooler will shut |
|
|
|
| down. In this case, prime the water cooler. |
|
|
|
| Refer to the Setup Overlay description in the |

|
| regardless of the overlay placed 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 and accessory |
|
|
|
| hoses for kinks, internal obstructions or block- |
|
|
|
| age, or ruptures. If such problems were found |
|
|
|
| then correct them and turn the machine off |
|
|
|
| and on to check if the beeping has been elimi- |
|
|
|
| nated. |
|
|
|
| 3. Check the water cooler fluid level. Low coolant |
|
|
|
| level could cause the pressure to drop. |
|
|
|
| 4. Prime the water cooler. Refer to the Setup |
|
|
|
| Overlay section of this manual for instructions. |
