Product Preparation

Prior to calibrating the machine you must first load product and prime the pumps. The product must be completely 

thawed and be within the temperature range of 35º - 40º F. If the product is not within the acceptable temperature 

range you will not be able to calibrate the machine to the product correctly.

Load Product

Step 1:

 Mix the product by vigorously shaking the product container.

Step 2:

 Wet or use a food grade lubricate on the container o-ring. This will ease removal of the container.

Step 3:

 Place the product in the cabinet and press it firmly into the bottle adapter opening.

Prime the Pumps

Step 1:

 Place a large container under dispense nozzle for the pump you wish to prime.

Step 2:

 Press and hold the dispense button, (“Stop/Plus” button if using portion control option), until concentrate  

dispenses from the dispense nozzle.

Ambient Conversion Kit (Optional)

The ambient conversion kit, (BUNN P/N: 33699.0001), allows remotely located ambient 

concentrate products to be used in place of dispenser mounted frozen concentrate 

products. One kit is required for each dispense station.

Step 1:

 Disconnect the dispenser from the power source.

Step 2:

 Remove the right side panel. Set the panel and screws aside for re-assembly.

Step 3:

 Open the dispenser door.

Step 4:

 Remove the decorative plugs from convenient openings at the right rear of the  

refrigerated compartment and the dispenser’s rear panel.

Step 5:

 Feed the free end of the Convertible Tube Assembly’s concentrate tube through  

the openings in the refrigerated compartment and dispenser rear panel. Take  

care to route Tube Assemblies so they won’t kink or interfere with the condenser fan.

Step 6:

 Connect the concentrate container to the free end of the concentrate tube protruding   

from the dispenser’s rear panel.

Step 7:

 Insert the Adapter end of the Convertible Tube Assembly into the desired bottle 

interface.

Step 8:

 Close the dispenser door.

Step 9:

 Install the right side panel with the screws set aside in Step 2.

Step 10:

 Apply power to the dispenser and prime the dispense tubing.

Step 11:

 Open the dispenser door and check for any signs of air bubbles in the dispense  

tubing. Any bubbles indicate the presence of a vacuum leak. When bubbles are 

present, re-check the fastening of all clamped connections, and positioning of the Adapter into the bottle  

interface.

Step 12:

 Close the dispenser door.

Calibrate the Machine

To calibrate the JDF Silver Series machines you will need to complete a couple of procedures. The first procedure 

required during calibration is to determine you water flow rate. This is accomplished by conducting the water flow test 

to identify your known volume of water being dispensed. The next procedure in the calibration process would be to 

conduct the total dispense test. You will then need to locate your product mix ratio, (usually found on the product con-

tainer). Using the total dispense ratio chart found in the “Installation and Operating Guide” you will need to determine 

if your total dispense matches your ratio target, if it does not you will need to make a pump speed adjustment.
