TIPS: The dispenser accessories and user interface are schematic diagrams for reference only. Due to product updates and upgrades, the actual product may differ slightly from the schematic diagram.

3. Quick Start Guide

• The product contains an instant heating and cooling system; maintain a space of 20 cm (8 inches) behind the machine for heat dissipation.
• Upon first powering on the appliance, the cooling function is enabled by default. Long press the water dispensing "?" and cold water key together for 5 seconds on the display interface to turn off the iced water function; use the same method to turn it back on.
• Once the cold water function is activated, to ensure optimal energy efficiency and a continuous supply of cold water, the machine will operate intermittently. It is normal to hear noise during operation.
• After the new dispenser has been powered on for the first time, it needs to wait for 30 minutes before the cold water function becomes available.

Installing the Filter

A diagram shows the filter installation process.

• Step 1: Take out filters from package and remove the wrapping.
• Step 2: Install the new filter, align the filter position marker with the machine marker, and gently press the filter until a “click” sound indicates successful installation.

Adding Water to the Tank

A diagram illustrates adding water to the tank.

• Step 1: Remove the water tank cover plate, and pick up the water tank in an upward direction.
• Step 2: Fill the feed water tank with tap water.
• Step 3: Place the water tank back into the dispenser, and cover it with the plate.
• Step 4: Push down on the water tank to secure it in place.

NOTE: When adding water, ensure it does not exceed the maximum water mark to prevent overflow.

Flushing the New Dispenser

A step-by-step guide with diagrams explains the flushing process:

• Step 1: Remove the filter packaging. Install the new filter.
• Step 2: Fill the feed water tank. Do not exceed the maximum water level line.
• Step 3: After the system is powered on, it will automatically flush the filter. When the feed water tank indicator "?" lights on, pour out remaining water and refill the water tank with water. TIPS: This step requires no action, just wait patiently.
• Step 4: The system will filter water into the pure water tank. When the "?" key flashes, place a container larger than 1.5L/52 oz, and press the "?" key to get water. NOTE: It is not recommended to drink water obtained during this step.
• Step 5: When the pure water tank indicator "?" lights on, repeat Step 4 again until the flushing of the two feed water tanks is completed, or the progress shows 100%. This step takes about 20 minutes in total, and the water can be drunk normally after completion.

NOTE: When the flush reaches 100%, clicking the water dispenser, exceeding 30 minutes, removing the feed water tank, or moving the pure water tank will exit the flush mode.

4. Operating Instructions

Water Dispensing

A series of diagrams illustrate the water dispensing process.

• Step 1: Touch the "?" button while the screen is off to wake up the display.
• Step 2: Cup Volume Selection: Place a container below the spout. Tap the cup volume Key "?" to switch and select the required water volume setting: 4, 8, 16, 20, 999 (max) OZ. Tap and hold for continuous cup volume adjustment (continuous watering until the feed water tank runs out).
• Step 3: Temperature selection: Tap the temperature key "?️" to switch and select the required temperature setting: cold water(59°F), ambient water(77°F), 113°F, 149°F, 185°F, 203°F.
• Step 4: Press the take water button "?" to dispense water. During water dispensing, pressing any key can pause the operation. The water output stops automatically when it reaches the set cup size.

Child lock operation

• When the temperature selection is hotter than or equal to 113°F, press and hold the child lock button "?" for 1 second to disable the child lock before pressing the water button "?" to dispense water.
• Hold the child lock key for 5 seconds to turn off the child lock function; this operation will cancel the hot water safety feature, so proceed with caution.
• After turning off, press and hold the child safety lock button for 5 seconds again to reactivate the child lock feature.

NOTE: Due to heating power limitations and feed water temperature, increasing the desired dispensed water temperature will result in a lower flow rate. The temperature of the feed water tank directly impacts the dispensing temperature of room temp water and the flow rate of hot water.

5. Additional Functions

Routine Flushing

• Continuous Standby Flush: When the machine is in standby mode for 24 hours continuously, it will automatically flush for 30 seconds, during which the water-filtering indicator "?" will flash. After finishing the flush, the machine returns to standby mode.
• Accumulative Water Production Flush: Once the machine has accumulated 25 minutes of water production, it will flush for 10 seconds. The water-filtering indicator "?" will flash during this process.
• In flush state, if the feed water tank is out of water or not installed, the machine will not enter the flush mode. It will wait until the flushing conditions are met to proceed.
• Power-on Flush: 30 seconds.
• Post Water Production Flush: 20 seconds.

Filter Resetting

a. Filter Replacement

WD-A2RF filter: Waterdrop Reverse Osmosis Membrane Filter. Service life: ≤12 months.

• Step 1: Lift the filter handle upwards to remove the old filter.
• Step 2: Install the new filter, align the filter position marker with the machine marker, and gently press the filter until a “click” sound indicates successful installation.

A diagram shows the filter replacement process.

b. Filter Resetting

After replacing the filter, hold the water dispensing key "?" for five seconds to reset.

Boiling Point Correction

Considering that the boiling point of water decreases with increasing altitude, it is advisable to adjust the boiling point at high altitudes to prevent scalding from boiling steam. The default setting is calibrated for low-altitude regions, so no adjustment is needed if you are at lower altitudes.

A table shows altitude, boiling point setting value, and maximum heating temperature:

Instructions for Boiling Point Correction:

• Step 1: Press and hold both the temperature and water volume buttons for 5 seconds to enter the boiling point adjustment mode.
• Step 2: The temperature section flashes at 203°F. Press the hot water button to cycle through settings with a step of 9°F. The adjustable range is 176°F/185°F/194°F/203°F.
• Step 3: Press the water dispensing key or if there is no operation for 10 seconds, the system will exit and save the boiling point data, which is remembered even if the power is disconnected.
