2. Set probe length.
• Adjust the length of the probe by pulling the B portion of the tube to its
proper length. Insert the probe into the bottle and push it down.
(See illustration on right)
3. Install bottle.
• Open door and place fresh bottle in front of tray.
• Clean fresh bottle with a soft cloth and warm soapy water then inse.
• Remove entire plastic cap from top of bottle.
• Insert probe into bottle.
• Push down on probe until it is seated.
NOTICE: When using a 5 gallon rectangular bottle, slide into place as shown in llustration below.
4. Plug cord into a properly grounded wall outlet.
• Water will be pumped into hot and cold water reservoirs from the bottle.
5. Turn energy saving switches on back of dispenser to ON.
• The red switch controls the heating of water. If you do not want hot water, leave this switch OFF
• The blue switch controls the cooling of water. If you do not want cold water, leave this switch OFF.
Notice:
• It will take up to 3 minutes for the reservoirs to load.
• Diring the use pump will come on to refill the tanks ,This is normal.
Initial Rinsing of Water Lines
This unit has been tested and sanitized prior to packing and shipping. During transit
dust and odors can accumulate in the tank and lines. fill with water.wait for 30 minutes,Dispense
classes of hot water and 6 glasses of cold water.
Dispense Cold Water
Note: After setup, it will take 2 hour to get water to maximum cold temperature. During this
time the compressor may run continuously. This is normal.
1. Position bottle, glass, pitcher or cooking pot securely below cold water tap.
• The right triangle below the cold water control indicates the location of the cold water tap.
• The circular shapes in the drip plate help align the flow of water. This unit dispenses
water at a fast rate. To avoid splashes, hold cup as close to the tap as possible.
2. Depress right control downward to start flow.
3. Release control once desired fill level is achieved.
Dispense Hot Water
This unit dispenses water at temperatures that can cause severe burns. Avoid direct contact
with hot water. Keep children and pets away from unit while dispensing. Never allow children
to dispense hot water without proper and direct supervision.
Note: After setup, hot water will be available in 15-20 minutes.
1. Position bottle, glass, pitcher or cooking pot securely below hot water tap.
• The left triangle below the hot water control indicates the location of the hot water tap.
• The circular shapes in the drip plate help align the flow of water. This unit dispenses water at a
fast rate. To avoid splashes, hold cup as close to the tap as possible.
2. Push hot water release button (red) inward and depress control downward to start flow.
3. Release control once desired fill level is achieved.
Replace an Empty Bottle
Notice: When your bottle is empty the dispenser will beep intermittently and the LED nightlights will
blink until a fresh bottle is connected.
You may also hear a sucking sound when the bottle empties. This is normal and is another way to be
alerted that your bottle is empty.
Replace empty bottle as soon as you notice it is empty. If unavailable, leave door ajar or unplug cooler
to stop beeping noise and flashing lights.
There may be a small amount of water left in the bottle. This is normal, if you need assistance please
contact customer service.
1. Open door and slide bottle out.
2. Remove probe from bottle:
• Pull probe straight up until completely out of bottle.
•hang probe on the door.
3. Install fresh bottle:
• Place fresh bottle in front of tray.
• Clean fresh bottle with a soft cloth and warm soapy water then wepe with clean wet colth.
