•Uses a 20’ length of 1/4” OD Water
Coil inside a Tank (called Ice Bank)
filled with water and ice.
•No reservoir of drinking water.
•3” thick slab of ice is formed on left
side of Ice Bank.
•Ice Bank Pump circulates water in the
Ice Bank, chilling the drinking water
inside the Water Coil.
•Ice Bank Pump is activated for
1minute, every time Cold or
Sparkling water is dispensed.
•Ice Bank Pump comes on automatically
for 1 minute, every 10 minutes.
•Level Sensor at front of Ice Bank
automatically fills and maintains
water level inside Ice Bank.
•Thermistor measures temperature inside
Ice Bank within 0.5 degree F.
•Separate valve used to fill Ice Bank

The Water pathway inside the ION is sealed and pressurized
in 1/4” OD tubing (about 23’ total inside the appliance).
Tap Water supply tubing connects directly at the rear of the
appliance to an Inlet Valve.
After the Inlet Valve, the water is directed to the Filter.
After the Filter,the Water travels up to the Ice Bank
Assembly,where it is either chilled inside a Stainless Steel
water coil, or bypasses to Ambient, Sparkling, or Hot
Water tubing.
After the Ice Bank, water is directed to Dispensing Valves at
the outlet of the appliance for Cold, Ambient, Sparkling,
and Hot Water.
KEY LEARNING - when you press one of the icons on the
Touch Panel, you are opening both the Inlet Valve and one
of the Dispensing Valves. You will always hear TWO valves
opening and TWO valves closing, in quick succession.
This double click is important when troubleshooting the
appliance and finding a valve which may not be opening
or getting electrical current to open.

FUNCTION – Water from Filter enters Ice Bank Assembly,
but is diverted with Tee fitting and bypasses the Ice Bank
Water Coil.
Blue Water Tubing from Ice Bank Assembly travels to Hot
Water Valve, attached to Hot Tank.
Hot Water tank is not pressurized, but extremely dangerous
to service when filled with Hot Water.To cool, turn switch at
rear of appliance to OFF.Then dispense water from using
Hot Water icon on Touch Panel until water is cool. Then,
water can be drained from Hot Tank by removing
1/4” plug at bottom of Hot Tank elbow fitting.
MANUAL FILL – On first STARTUP only, the software will
force you to make sure the Hot Tank is filled. On every
subsequent STARTUP, make sure the ON/OFF Switch at
rear of appliance is in OFF position before connecting
electrical power.
TRANSPORTATION – It is not necessaryto empty the
Hot Tank before transport, except in temperatures below
freezing. The only outlet for water is through the Faucet. The
Hot Tank contains about 4 lbs of water and can be emptied
to make the appliance lighter to carry.
