The Water Pathway inside the ION is sealed
and pressurized.
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 Manifold
Flow Meter Assembly, the Filter, and an internal pump (if
installed).
After being filtered, the water is either chilled inside the
Water Coil or Carbonation Tank, or bypasses to Ambient or
Hot Water Tubing.
Water is then directed to Dispensing Valves at the outlet of
the appliance for Cold, Ambient, Sparkling and Hot Water.
KEY LEARNING: Pressing the Cold, Ambient, or Hot
dispense button on the Touch Screen opens both the Inlet
Valve and one of the Dispensing Valves. TWO Valves open
and TWO Valves close, in quick succession. Dispensing
Sparkling water opens the Dispense Valve only; the Inlet Valve
opens when the Carbonation Tank refills.
TRANSPORTATION: In temperatures below
freezing, Filter and water must be removed from
appliance before transporting (See pages 30).
