4. Setup and Installation
Follow these steps to set up your water dispenser:
- Unpack: Carefully remove the dispenser from its packaging.
- Placement: Place the dispenser upright on a level, stable surface. Ensure there is at least 4 inches of clearance from walls to allow for proper ventilation.
- Clean: Wipe down the exterior of the dispenser and the drip tray with a soft, damp cloth.
- Install Drip Tray: Slide the drip tray into its designated slot below the spouts.
- Load Water Bottle: Remove the cap from a 3 or 5-gallon water bottle. Carefully lift the bottle and place it onto the anti-dust mite water barrel seat on top of the dispenser. Ensure the bottle is seated firmly and water begins to flow into the dispenser's reservoirs.
- Prime the System: Before plugging in, dispense water from both the hot and cold spouts until water flows continuously. This removes air from the system.
- Plug In: Connect the power cord to a grounded electrical outlet.
- Activate Heating/Cooling: Locate the hot and cold power switches on the back of the unit. Turn them ON. The indicator lights on the front will illuminate.
