REMEDY

The air filter and condenser MUST be cleaned regularly. Any dust buildup will affect cooling ability.

Have a qualified service person check the refrigerant charge.

(A)The DAY/NIGHT Switch must be in the “DAY” position.

(B)Refer to Service - DAY/NIGHT Switch for testing procedures. See page 36.

Bunn recommends the use of prod- ucts with an apparent brix of 12 or higher.

Refer to Service - Voltage Divider for testing procedures. See page 50.

Turn the Ice control for the desired hopper a small amount clockwise to increase the ice granule size or counterclockwise to decrease the ice granule size.

Adjust the sugar content of the product. Increasing the apparent brix results in finer ice granules. Decreasing the apparent brix results in larger ice granules.

Always lubricate the dispenser as directed in this manual before reas- sembling and using the dispenser.

Use the cooling drum support to determine that the auger shaft is still the proper distance from the hopper drip tray. The cooling drum may be gently lifted to return it to the nec- essary horizontal position. Refer to Service - Cooling Drum Alignment. See page 35.
