Bottle water coolers need to be cleaned periodically to prevent mineral build-up inside the heating tank.
Heating tanks may require cleaning when:
1. Normal hot water flow appears restricted.
2. Noisy heating cycles are heard.
3. Water in the cooling tank is very warm.
4. Mineral build-up has imparted a taste to the water.
PLEASE READ AND FOLLOW ALL DIRECTIONS TO PREVENT DAMAGE TO THE UNIT AND TO THE USER.
CAUTION: Because this cleaning process involves very hot water that may scald, the
use of rubber gloves is recommended. KEEP CHILDREN AWAY.
1. Disconnect the power supply cord.
2. Draw water from the hot faucet until the water is cool.
3. Remove the bottle from the unit. CAUTION: A nearly full bottle of water weighs
over 18 kg and can be awkward to handle. It may be necessary for you to drain
water from the bottle until it becomes manageable.
4. Drain water from the reservoir through the cold faucet.
5. Place a bucket or pan under the black drain valve located at the rear of the cooler.
6. Turn the valve’s petcock counterclockwise to open. CAUTION: HOT WATER
CAN SCALD HANDS.
7. Turn the drain valve to a closed position when the tank is empty.
8. For easy access to the hot tank inlet tube, remove the reservoir by unscrewing the cold faucet (blue handle) and pulling upward on the reservoir’s lip.
9. Remove the baffle from the reservoir.
10. Place a funnel with an 8 mm diameter end into the supply tube.
