Principles Of Operation - WaterLogic WL3FW FIREWALL Manual

The WL3FW is a pressure fed machine that utilizes mains supply to push water through the unit to the
faucet. The WL3FW can provide Cold, Ambient, Sparkling, Hot and Extra Hot water with a modern
touch-to-dispense interface. The WL3FW has a single cold tank (4 Litre free standing and 2 Litre mini)
and high efficiency cooling system. Filtration can be customized to meet your specific water conditions.
The patented Firewall purification system purifies the ambient and cold water before it is dispensed
while providing a sanitary faucet and preventing outside contamination back into the water circuits.
Our advanced UV sensor measures the dose of UV through the water stream to guarantee the safety of
the water. The Firewall purification system will not allow unsafe water dispense and alarms the user if
the system is inactive.
