Operational Information
WL850 HV
moving of the small switch will allow just the hot button to be pushed to vend
ambient water. This option does allow you to convert the machine for one button
operation for hot water. All machines are factory set at two-button operation for hot
water. Any change of the button configuration for use in hot water dispensing is the
responsibility of the distributor if so required. Waterlogic strongly advises against
the use of a one button operation for a hot water. The PCB also has a UV failure
alarm, and timer switches that can set the UV lamp on time as 3 minutes, 10 minutes
or constant.
COLD TANK
The cold tank is manufactured from 304 Stainless Steel which is non-corrosive,
inert and reflects Ultra Violet Light (UV). The tank system consists of a double
tank assembly. The cold water temperature should be set at 5ºC, this being ideal
temperature for a cold drink. The capacity of the tank is two litres. When the water
is stored in the Cold Tank it is chilled and exposed to UV at the same time, this
protects the water from Bacteria growth.
UV LAMP
The UV light is an 8watt germicidal lamp at a wavelength of 253.7 NM, which is
very efficient at destroying Bacteria found in water. UV radiation kills Bacteria by
destroying the DNA nucleus of Bacteria. An 8-watt lamp is at peak performance
for six months and then should be changed. Tests prove that the 8-Watt lamp in
combination with a 2 litre stainless tank has a very effective kill rate of Bacteria. The
lamp is immersed in the cold tank and protected by a quartz sleeve which allows UV
radiation to pass through to the water. When the lamp is changed the quartz sleeve
should be removed and cleaned also.
The UV lamp can be set to 3 minutes, 10 minutes and constant time on the PCB.
The WL850HV is available
in following options:
a) Cold, Hot & Sparkling
b) Cold, Ambient & Sparkling
c) Cold & Sparkling
When reading this manual,
note the differences between
theoptions and focus on the particular
sections that concern the unit installed.

PCB
The PCB controls the solenoid valves, the pump level probe, the LED power and
warning light. There is also a small switch mounted on the back of the PCB that
will change the function of the hot button. On a hot and cold machine, the hot and
sparkling button must be pushed together for hot water. But on an ambient machine
