G SERIES MODELS - ERROR MESSAGES

1.) “FILTER CLEANING” ALARM

A filter cleaning alarm will activate when the unit is running hot due to insufficient internal air circulation. When this occurs a “Filtr” message will appear on the touchpad LED readout and an intermittent audible tone will also sound to alert the operator of this condition.

The “Filtr” message will appear when the alarm activates (a beeping sound every 4-5 seconds). To determine the condition that caused the alarm and correct problem, see list of conditions below:

•Condition: The filter is dirty and needs to be cleaned. - Corrective Action: Clean and replace filter following instructions on page 11 (Removing and Cleaning Filter).

•Condition: The unit is positioned too close to a wall or other object restricting air flow and causing the

machine to run at a higher temperature. - Corrective Action: Reposition unit to maximize ventilation space (see page 2 - installation figures).

•Condition: The filter is not properly installed. - Corrective Action: Properly install filter see “Removing and cleaning filter” page 11.

•Condition: The unit has been installed near a heat source, such as a coffee machine, ice maker or cold beverage machine which expels hot air from its vents, causing the machine to run at a high temperature. (Installation near a heat source should be avoided) - Corrective Action: Reposition unit to maximize ventila- tion space (see page 2 - installation figures).
