2. Remove the drip tray from the unit by pulling straight out. Once removed, locate the
single screw that holds the lower front panel in place and remove it. Then, press down
on the top of the panel and pull outward. The panel should hinge outward and then
come away from the unit completely. Set this panel aside.
3. Remove the top cover. To do this remove the two screws at the back
of the top cover, slide the cover backwards, and lift away from the
unit. Shut off the water supply and remove the lid of the Cold tank.
4. Add the recommended amount of an approved sanitizing agent OR
descaling solution (but not both) to the water inside the cold tank and
gently mix. Allow this mixture to sit in the tank for at least 10 minutes.
After 10 minutes have passed, position a bucket or large container under
the white drain cap on the left side of the unit, behind the lower front
panel. Remove the cap to this drain port and allow the solution to drain
into the bucket. With a pitcher ready, dispense cold water until the tank is
empty.
5. Once the tanks have completely drained, cap the drain port, and open the water supply
line to allow water to fill the tanks once more. Once full, open drain again and dispense
cold water until the tanks are empty. Repeat this step one more time for a total of three
flushes.
6. Cap the drain port and turn the water supply on. Place
the tank lid back into position and allow the tanks to
fill for the fourth and final time. Once the tanks are
full, and using the touch sensors on the front panel,
dispense both hot and cold water to ensure flow from
tanks.
7. Turn the hot tank switch on the back of the unit to ON. Return the front lower panel and
top panel to the unit and reinstall all fasteners. The unit is now ready for use, and the
hot water will be up to temp within 15min.
