WL7 FW
PRINCIPLES of OPERATION - DISPENSING
It takes the
WL7 FW Water Purification System
approximately 10 minutes to heat 1.5 liters of water in the hot
circuit and 2 hours to build a full ice bank in the cooling system. The
WL7 FW
has an optional 700 mL
carbonation tank that yields 500mL premium sparkling water per batch in the center of the ice bath. WL7 FW
is a pressure fed system and output is dependent on supply. WL7 FW contains a Firewall purification system
to purify cold, ambient, and sparkling water at the point-of-dispense. There is a 2 second delay before every
Firewall dispense to sanitize the delivery path and ensure safety of water.
Dispensing Cold Still Water from the
WL7 FW Water Purification System
Rotate the control ring to the cold icon and press and hold the dispense button until
purified water flows to the faucet. There will be a 2 second delay as the Firewall purifies
the faucet. Cold dispense opens solenoids 1 and 5, which allows supply water to push
through the stainless-steel drinking coil in the ice bath and Firewall purification system to
the cup. The
WL7 FW
defaults to cold water selection when idle as a safety feature. The circulation
motor will be on for 4 minutes after every dispense.
Dispensing Ambient (Room Temperature) Water from the
WL7 FW Water Purification
System
To dispense ambient water, rotate the control ring to the ambient icon and press and hold
the dispense button. This opens solenoids 1 and 2, which allows water to push thru the
Firewall purification system to the cup.
Dispensing Hot Water from the
WL7 FW Water Purification System
To dispense hot water, rotate the control knob to the hot icon and press and hold the
dispense button. There will be a 2 second safety delay as hot warning appears in the
display, continue to depress until hot water flows to faucet. Solenoid 1 and 3 will open to
and allow water into the hot tank and hot water from the tank will flow to the faucet.
Dispense defaults back to cold after 5 seconds of inactivity as a safety feature to prevent
accidental dispensing of hot water. There will be a couple seconds of hot water carry on after
releasing the dispense button as the hot tank depressurizes.
