Setup
Follow these steps for initial setup of your Primo water dispenser:
- Unpacking: Carefully remove the dispenser from its packaging. Inspect for any damage.
- Placement: Place the dispenser on a hard, level surface. Ensure there is at least 4 inches of clearance from the wall for proper ventilation.

- Prime the System: Before turning on the heating or cooling, dispense water from the cold and hot spouts until water flows steadily. This removes air from the lines.
- Activate Heating/Cooling: Once primed, turn on the hot and cold water switches located on the back of the unit. Allow approximately 15-20 minutes for water to reach optimal temperatures.
