Machine Overview
WATERLOGIC WL2 FIREWALL
COLD TANK
The cold tank is manufactured from 304 Stainless Steel which is non-corrosive and
inert. The cold water temperature is pre-set at approximately 5°C by the factory, this
being the ideal temperature for a cold drink. The capacity of the cold tank is 4 litres
for freestanding models and 2 litres for mini models. The cold tank temperature
is controlled by a thermostat that is set at the factory. The thermostat set point is
marked at the back of the machine by a small dot. If the WL2 Firewall UV light fails,
then no cold water will be dispensed.
HOT TANK
The hot water tank has a 1.5 litre capacity for free standing and mini models. It is
manufactured from 304 stainless steel and is heated by a 500watt heating element.
The temperature of the hot tank is controlled by a thermister and it is pre-set at the
factory at approximately 87°C. A BI-metal overload thermostat is fitted to stop the
tank overheating and can be reset manually. Setting the hot water temperature at
87°C also helps stop scale forming in the hot tank. A special polyphosphate filter
can be fitted at the customer’s request, that will help inhibit lime scale formation. A
minimum flow rate of 1litre per minute is needed for the hot tank to operate correctly.
FILTERS
The filtration system on the WL2 Firewall is designed to reduce dirt and sediment
particles from the water. Furthermore, the Activated Carbon process will remove a
whole range of contaminants e.g. chlorine and pesticides. There are many kinds of
different filter combinations available from Waterlogic to suit local water conditions.
The WL2 Firewall is available in the following
options:
a) Cold Only
b) Cold & Ambient
c) Cold & Hot
When reading this manual, note the
differences between the options and focus
on the particular sections that concern the
unit you have installed.
