LOADING

Frozen Concentrates

1.Thaw the frozen concentrate in a refrigerated 35-40 degrees F (1.6-4.4 degrees C) environment for 36 to 48 hours before use.

2.Thoroughly mix the thawed concentrate by vigorously shaking the product container.

3.Open the dispenser door.

4.Prior to placing the product container in the dispenser, make sure that the o-ring on the container adapter is lubricated. This will ease removal of the container when it becomes necessary.

5.Place the product container in the desired position and press it firmly into the bottle adapter opening.

6.Open the vent hole in the product container.

Note: Concentrate in the container must be completely thawed and be within the temperature range of 35-40 degrees F (1.6-4.4 degrees C.) Product outside of this temperature range, especially below, will produce an “out of brix” drink.

Ambient Concentrates (Optional)

1.Install an Ambient Concentrate Conversion Kit (BUNN-O-MATIC part number 33699.0001) per the instruc- tions provided in the kit.

2.Attach the concentrate product hose to the appropriate concentrate line located at the rear of the dispens- er.

3.Close the dispenser door.
