Setup
- Unpacking: Carefully remove the water cooler from its packaging. Remove all plastic wrap and tape.
- Placement: Place the unit on a firm, level surface. Ensure there is at least 4 inches of clearance from the wall to allow for proper ventilation. Avoid placing it in direct sunlight or near heat-generating appliances.

It is recommended to run several batches of cleaning solution (e.g., a mixture of 1/3 white vinegar to 2/3 water) through the unit, followed by several glasses of clean water, to thoroughly flush the system.
- Water Bottle Installation:
- Clean the neck of the 3 or 5-gallon water bottle.
- Remove the cap from the water bottle.
- Carefully lift the water bottle and invert it, placing its neck into the support collar on top of the dispenser. Ensure it is seated firmly.
