INSTALLATION AND LOCATION OF THE DISPENSER

1. Location of Dispenser:

1.Place the dispenser where it will best serve your operation.

•Do not block the vents at the top rear of the dispenser or under the dispenser. The vents must be free and open to ensure proper operation of the ventilation system and to prevent over-heating and damage to the system.

2.Make sure that counters, platforms, and shelves are strong enough to support the dispenser and full containers of product.

3.Place the dispenser at the appropriate serving height so that staff drawing product from the dispenser can operate the levers as well as easily place and remove cups.

4.The dispenser must be placed on a level surface or leveled by adjusting the legs. The dispenser must be level to ensure proper functioning of the refrigeration system. Use a bubble level to ensure accuracy.

5.Do not remove the legs from the dispenser or allow the dispenser to sit flat on the counter.

•Airflow and circulation under the machine are essential for the proper operation of the refrigeration system.

•Make sure the legs at the four corners of the bottom of the dispenser are in place. If one has loosened during shipping, re-tighten it. Some dispenser models have adjustable legs and these legs are secure even though they may appear to be loose.

•Removal of the legs automatically voids the Warranty.

6.The dispenser is not suitable for outdoor use.

STARTING THE DISPENSER
