Machine Overview
WATERLOGIC 1000 GF COLD TANK CAPACITY (4 Litres)
The cold tank is manufactured from 304 Stainless Steel which is noncorrosive and
inert. The temperature of the Cold Tank is controlled by a mechanical thermostat
located on the rear panel of the machine and can be set between 3°C and 12°C. We
recommend the cold water is set at 5°C, which is the factory setting and is the ideal
temperature for a cold drink. The set point for the thermostat is marked with a
black dot.
HEADER STORAGE TANK 11.5 Litres
The plastic header tank has a capacity of 11.5 litres of purified water. This tank can
be drained and removed from the machine for cleaning. It is made with Biocote
additive to inhibit any bacteria growth.
The level of the header tank is controlled by an electrical float switch which controls
the inlet solenoid valve and Reverse Osmosis System. There is a mechanical float
valve to control any tank overfill and gives an overfill failsafe feature.
HOT TANK 1.5 Litres
The hot tank has a capacity of 1.5 litres and is made of stainless steel. The water
temperature is controlled by a Mechanical Thermostat and is factory set at 85°C. A
thermal high temperature cut out is fitted to the Hot Tank and the tank has a 500
Watt immersed heating element. The high temperature cut out has a manual reset
button, please isolate the power before resetting. The hot water tank is a sealed unit.
The WL1000 GF is available in the following
option:
• Freestanding Cold, Hot and Ambient
with Reverse Osmosis (RO) Filtration.

REVERSE OSMOSIS FILTERS
The filtration system is a 4-stage system, consisting of sediment, pre-carbon,
Reverse Osmosis membrane, and post carbon filters.
REVERSE OSMOSIS WATER PUMP
The 1000 GF is fitted with a water pump and pressure switch to ensure a constant
pressure across the RO membrane. If the input water pressure falls below 1.5 bar
then the water pump will not run. The water pump outlet pressure is 60 PSI allowing
the membrane to meet 50GPD water production
UV LAMP
The UV light is an 8 Watt germicidal lamp at a wavelength of 253.7 NM, which is
very efficient at destroying bacteria in water. The UV lamp is situated in the cold
tank surrounded by a quartz sleeve. The lamp must be replaced at 6 months
intervals, and the quartz sleeve cleaned.
PCB
The PCB (Printed Circuit Board) is the indicator and pump control unit for the WL
GF1000, the display (at the top of the GF1000) informs the user of the status of the
unit. There are three different LED lights on the display PCB showing power on,
heating, or cooling status of the machine.
COMPRESSOR
The compressor operates at 220-240V at 50Hz. It uses 75 grams of R134a non-
Ozone depleting refrigerant gas. Do not place the machine too near a heat source
as it will affect the compressor efficiency.
WATER PIPE AND FITTINGS
The inlet water pipe adaptor and the internal water circuit pipe sizes are 1/4”, 5/16”
and.3/8”. The entire internal water circuit and all the components which come in
contact with water are food grade approved.
INLET WATER VALVE
The inlet of water to the machine is controlled by means of a 230V AC electrical
solenoid valve. The valve is energized by the header tank electrical float switch.
There is also a leak detection float switch located in the base leak catchment tray
of the machine that will cut electrical power to the inlet solenoid valve should there
be a internal water leak. The inlet valve comes with a pipe reduction fitting to allow
a ¼” pipe connection.
PLASTIC PANELS
The moulded panels are made from recyclable ABS plastic. All the ABS plastic
panels are UV resistant and meet the standards of CE and UL. Please note that the
1000 GF should not be exposed to direct sunlight. Placing the 1000GF in direct
sunlight from a window, close to a radiator, or in a room of high ambient temperature,
will affect the efficiency of the refrigeration circuit.
