WL500
PRINCIPLES of OPERATION
It will take the
WL500 Water Treatment System
approximately 10 minutes to heat 1.6 liters of water in
the hot circuit and 45 minutes to chill the 4 liters of water in the cold circuit to set point temperatures
after all tanks have been properly filled. The
WL500 Water Treatment System
has two Cold Tanks; a 2
liter UV Cold Tank and a 2 liter Sparkling Cold Tank which is separated by a baffle/divider plate that
isolates a 1 liter Sparkling Water Chamber from a 1‐liter Pre‐Chill Chamber within.
Dispensing Cold Still Water from the
WL500 Water Treatment System
The
WL500
Water Treatment System
defaults to cold water selection when idle. “COLD” will appear on
the display and cold water will be dispensed when the Main Dispense Button is pressed. Selecting COLD
(Button 1) and then pressing the Main Dispense Button opens Solenoids 2 and 4, which allows supply
water to push into the Pre‐Chill Chamber of the Sparkling Cold Tank. Pressurize feed water pushes into
the bottom of the pre‐chill chamber and forces pre‐chilled water through the tall draw tube into the
bottom of the UV Cold Tank. UV treated, cold, still water is forced out through the tall draw tube,
through Solenoid 4, out the faucet of the dispenser. When the main dispense button is released, both
Solenoid 2 and 4 will close, thus stopping cold, still water output. The
WL500 Water Treatment System
is a pressure fed unit and output is dependent on supply.
