WARNING: Before plugging in the unit, make sure to have poured water from the hot water faucet. IF THE DISPENSER IS TURNED ON WITH AN EMPTY WATER TANK IT CAN BE DAMAGED.

  1. Let the appliance stand upright for about 24 hours. This will reduce the chance of malfunction in the cooling system from possible mishandling during delivery. WARNING: The drain cap on the back of the unit may become loose during shipping. Fasten the drain cap tightly before you start to operate the unit. If the drain cap is loose, the unit may leak and cause floor damage.

  4. Insert the power plug into the wall socket.
  5. First, turn the hot water switch on the back of the unit into the ON position. Next, turn the cold water switch into the ON position.
    DO NOT TURN ON BOTH SWITCHES AT THE SAME TIME. Once this is completed both cooling and heating indicator lights should light up.

NOTE: The appliance is designed to provide hot or cold water whenever you need it. It will automatically turn on and off when hot and cold water reaches the desired temperatures.
When operating the water dispenser for the first time, you will need at least 15-30 minutes for the hot water to reach the desired temperature and 1 hour for the cold water to reach the desired temperature.
The water dispenser has 3 indicator lights on the front panel.

  • When the right (icon) indicator light is on, the unit is in the process of cooling water inside the cold water tank.
  • When the left (icon) indicator light is on, the water dispenser is heating water inside the hot water tank.
  • When you plug the water dispenser in, the middle (icon) indicator will be turned on. This means that room temperature water can be dispensed.

Using the water dispenser

  • To dispense hot water, press the hot water safety button and then push the hot water button down.
  • To dispense cold water, push the cold water button down.
  • To dispense room temperature water, push the room temperature button down.
  • To use the Cold Water Temperature Regulator, turn the knob clockwise to get colder water and turn the knob counter-clockwise to get warmer water. The default temperature is 45°F.
  • It is recommended that if the hot water option is not used, the hot water button (red switch) be turned OFF. This will help conserve energy.


WARNING: Before cleaning, turn the power switch off and disconnect the power cord from the wall.

  1. Before the first use and after a long period of not using the appliance, the water tank and water pipes should be cleaned. It is recommended to wash and disinfect the system every 3-6 months.
  2. To begin cleaning, all water must be drained from the unit (turn heating switch to OFF while draining the system). Open the lower door and remove the water bottle from the unit; remove water straw from water bottle.
  3. To clean, rinse the unit and its parts several times with boiling or purified water. After rinsing, tilt the dispenser to drain any remaining water. Once this is done, dry the unit with a rag or soft cloth.
  4. If the appliance is not going to be used for a long period of time, unplug it and drain all water in its interior.
