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.

Hot Water Status
The heater switch must be on for hot water
production. A flushing or moving status bar
indicates the heater circuit is on and the arrows
on the status bar reflect the temperature in the
tank from 40⁰C (104⁰F) on left to hot set point
on right of scale (default is 87⁰C or 189⁰F).
Dispensing Extra Hot Water from the WL7 FW Water Purification System
Extra hot water is available for steeping tea or making soups. To temporarily raise the hot
water temperature in the hot tank, users can select extra hot product icon and press and
release the dispense button to activate extra hot cycle. Extra hot set temperature is factory
set to 95°C (203°F) and can also be programmed to 87°C (189°F), or 80°C (176°F) if desired.
Activating extra hot cycles the heater on until extra hot set point is achieved. Extra hot ready will be
displayed above the status bar and the extra hot temperature indicator arrows will be all the way to
the right side of the scale. The extra hot product icon will display a small status bar below the icon
validating the extra hot cycle is active and arrows on the status bar will indicate the temperature in
the hot tank.
The status bar will be moving or flushing when heater is on. The
arrow location will indicate temperature in the tank from 40⁰C
(104⁰F) on left to extra hot set point on far right of scale (default is
95⁰C or 203⁰F). The hot tank will return to the hot temperature
set point once the extra hot cycle is complete (temperature must
reach extra hot set point).
