5.  STARTING UP THE DISPENSER

 

5.1  Leak Check and Prime

1

Remove the side panels by loosening the two screws located at the bottom of the panel and then 

lifting off the frame.

2

Remove the drip tray by lifting up and pulling away, then remove access panel to expose the 

solution modules.

3

Connect the BIB connectors to the syrup BIBs.

4

Turn on the water and the gas supplies.  Ensure both are flowing to the dispenser.

Note:

  The water and syrup pumps will activate loudly until the lines are pressurized.

5

Thoroughly check for leaks at all connections.

6

Install a 1/4” ID tube on the sample port shown in 

Figure 5.1

.  Check that the water and syrup 

shutoffs are on (as shown in 

Figure 5.2

) and then open the sample valve and collect the water/

syrup in a cup.  Continue to prime until syrup flow has been established and all air has been 

removed from the lines.  Discard the samples.  Repeat for all barrels.
