Machine Overview
WL 3000 COLD TANK
The cold tank is manufactured from 304 stainless steel which is noncorrosive,
inert and reflects ultraviolet light. The temperature of the cold tank is controlled
by a microprocessor and can be set between 3 degrees and 12 degrees °C. We
recommend the cold water be set at 5 degrees °C, this being ideal temperature for
a cold drink. The capacity of the tank is two litres and it is sealed with the ultraviolet
(UV) light in the centre. 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.
HOT TANK
The hot water tank has a two litre capacity; it is manufactured from 304 stainless
steel and is heated by a 1350 Watt heating element. Temperature of the hot tank is
controlled by the Microprocessor and can be set between 70°C and 95 degrees °C.
It is recommended that hot temperature is set at 87 degrees °C, this being the ideal
temperature for instant drinks. A thermal cut out is fitted to the hot tank to prevent
overheating. The tank is fed water via a scale inhibiting filter to increase the tank
life. Setting the hot water temperature at 87 °C also helps stop scale forming in the
hot tank.
COLD AND SPARKLING TANK
The WL3000 incorporates a unique and patented split tank to make sparkling water.
This technology is part of a double tank system that allows rapid regeneration of
carbonated drinks and high volume of cold still water.
The WL3000 is available in five
options:
a) Cold, Hot & Sparkling (Full Option)
b) Cold & Hot
c) Cold & Ambient
d) Cold & Sparkling
e) Cold Only
When reading this manual, note the
differences between the options and
focus on the particular sections that
concern the unit installed.

WATER VALVES
Dispensing of water to the customer is achieved by means of a 24V DC electrical
solenoid valve. The valves are energized every time the customer pushes the
dispense button for a drink. DC voltage is used to give a positive and quieter action
of the solenoid valve.
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 machine should not be exposed to direct sunlight. Placing machines in direct
sunlight, or close to a radiator, or in a room of high ambient temperature will effect
the efficiency of the refrigeration circuit.
PARTS REQUIRED FOR SPARKLING WATER
CO
2
Cylinder & Gas Regulator: The units with the option of sparkling water will need
CO
2
gas, food grade carbon dioxide. This gas is stored in cylinders in a liquid form.
The cylinders are usually painted grey or black (regulation requirement for CO
2
). The
gas regulator, which comes with the unit,controls the flow of CO
2
to the carbonation
tank; it reduces the pressure of the CO
2
gas to 45PSi which is needed to make high
quality sparkling water.
Water Pump: The pump is 24V DC and forces the pre-chilled cold still water into
the carbonation tank at a minimum pressure of 45 PSi. This pressure is required to
overcome the internal pressure from the CO
2
gas which is in the tank.
FILTERS
The filtration system on the WL3000 is carried out in three stages. Stage one is
the reduction of dirt and sediment particles from the water. Stage two is a Granular
Activated Carbon (GAC) process which will remove a whole range of contaminents
e.g. chlorine, pesticides. Stage three is a second GAC filter removing any remaining
contaminates. It is important for the UV sterilization system to be supplied with
clean water in order to achieve maximum efficiency. If the water is not cleaned of
particulate matter, this will restrict the penetration of the UV radiation into water.
There are many kinds of different filter combinations available from Waterlogic to
suit local water conditions.
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 found in water. UV radiation sterilises 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.
PCB
The PCB (Printed Circuit Board) is the control unit for the 3000; it is responsible for
the functions of all the mechanical and electrical parts (24V DC). The microprocessor
drives a Liquid Crystal Display (LCD) which informs the user of the status of the unit.
On this model there have been added functions that will make the unit more flexible
to the customers needs e.g. option of different languages, sleep mode.
COMPRESSOR
The compressor operates at 220-240V and at 50Hz. It uses R134 a non-Ozone
depleting refrigerant gas. There is also the option to use natural refrigeration gas.
WATER PIPE AND FITTINGS
The inlet and the internal water circuit pipe size is 6mm and 8mm. The entire internal
water circuit and all the components which come in contact with water are food
grade NSF / WRAS approved. The Cold, Ambient and Sparkling water tubing inside
the machine should not be exposed to water above 25˚C.

Installation Procedures
Important notice: This procedure should only be carried out by an engineer or
staff trained by Waterlogic International or an approved distributing agent.
NOTE: This appliance is intended for indoor use only and must not be installed in
any area where a water jet could be used.
1. Site the machine with a 50mm air gap at both sides and back. Mount the machine
on a firm flat surface so that it cannot topple over.
2. Level the machine using the adjustable feet.
3. It is advisable that the water supply and electrical supply is within 2 metres of the
machine and that the plug is accessible.
4. Undo the screw located in front of the dispense nipple. Lift and tilt the front door
panel towards you.
5. Unscrew the top cover by removing the six screws which keep it in place. Two are
located at the back of the machine, and four at the front underneath the front door.
Remove the top cover by lifting it from the sides and the back, this will allow you
access the high voltage area.
6. If installing a unit with the option of sparkling water please continue reading. If
not, go directly to no 7. Prepare the gas bottle by removing the dust cover (if fitted).
Face the gas outlet away from you and momentarily turn the gas on and off by
twisting the knob located on the gas bottle. This will allow a high pressure burst
of CO
2
gas to clean any dust and dirt from the fittings. Attach the gas regulator to
the bottle and the gas pipe to the push fitting on the regulator. The pressure of the
regulator should be set by the factory at 45PSi. Locate the gas bottle upright in a
secure area near the machine or the base cabinet.
7. Make the water connection to the water supply pipe using an installation kit. Turn
on the water supply and flush the pipe until water supply runs clear of any dirt, then
make the water connection to rear of the machine. Ensure that the water supply is
turned on. The size of the pipe required is 1/4”. The minimum working pressure is 30
PSi/2 Bar. The ideal pressure is 42 PSi/3 Bar.
8. Check the electrical socket, if required, and then make the electrical connection
to the machine, by plugging the power lead into the rear of the machine, then
connecting to the electrical socket. Make sure that the red and green switches
located at the rear of the machine are off when you turn on the electrical supply to
the machine. Do not at this stage turn on these switches.
9. The water temperature of the machine is factory set for cold still water at 5°C and
87°C for hot water. Sparkling water will automatically be colder than the still water
as the cold tank system is designed to do this. Temperatures can be adjusted in
section ‘Programming Instructions’.
10. If installing unit with option of sparkling water please continue reading. If not go
directly to no 11. Purge CO
2
gas through the carbonation tank by lifting the yellow
lever on the relief valve located on top of the carbonation tank for a few seconds.
11. Inspect all the water connections and all the electrical connections.
12. Replace the top cover on the machine and the front door.
13. Turn on only the red power switch at the rear of the machine.
14. Observe the LCD display illuminating and running self-test.
15. Depress the hot water button followed by the main button, flush 10 litres of water
through the hot tank. The first few litres of water will have a dark appearance. This
is due to a small amount of carbon being released from the water filter when new. It
is harmless and will disappear very quickly whilst you flush the machine.
16. Depress the cold water button followed by the main button, flush 5 litres of
water through the still cold tank.
17. Check the machine for any water or gas leaks.
18. Once satisfied that water is passing through the hot, cold and sparkling tank
successfully, turn on the green heater compressor switch (green switch). The
machine will now start to heat and chill.
19. The hot water will heat rapidly, but it will take approximately 40 minutes before
the cold temperature reaches the set point.
20. When the machine has reached the target temperature, the compressor will
stop running. The temperature will continue to drop as any ice that has formed on
the sides of the tanks will start to melt and equalize the tank temperature.

WL3000 Technical Manual - May 2014
SANITIZING THE MACHINE
1. You will need to have an empty in-line filter housing to follow this procedure. Also
sanitiser, disposable rubber gloves, and bacterial wipes or spray.
2. Mix a solution of sanitiser in the empty in-line filter housing.
3. Turn off the water supply to the machine and release the internal water pressure
by depressing the dispense button momentarily and remove the water supply pipe.
4. Isolate the power to the machine.
5. Bypass the internal twist filter to avoid mixing sanitising solution with the active
carbon.
6. Connect the outlet of the empty in-line housing to the inlet of the machine and
connect supply water pipe to the inlet of the empty in-line housing.
7. Turn on the power and water supply to the machine.
8. Depress the blue dispense button until the sanitation fluid starts to flow out of
the faucet nipple.
9. Allow the sanitation fluid to stand in the machine for 20 minutes.
10. Do not let any sanitation fluid enter the hot tank.
11. Then flush the cold water until the water runs clear of sanitiser.
12. Again isolate the water to the machine and release any internal water pressure
now isolate the power.
13. If this procedure is being done in conjunction with the 6 monthly services then
change the filter.
14. Remove the empty in-line filter housing from the back of the machine and re-
connect the water supply pipe to the back of the machine. Reconnect the filter.
15. Turn on the power and water flush the machine until the water runs clear.
16. Visually inspect water connections for any leaks.
17. Remove the faucet nipple and inspect to see if there are any cracks or scratches
or lime-scale build up on the nipple, if so then replace it. If the faucet nipple is OK
then sterilise it and put back using clean rubber gloves.
18. Remove and clean the drip tray, and grill. If the grill is damaged or heavily stained
and you are unable to clean it then it is advisable to replace the grill.
19. Wipe all surfaces around the drip tray and faucet nipple area with a bacterial
wipe or spray.
20. Return the drip tray to position.
21. Flush a further 15 litres of water if you have changed the filter and ensure there
are no carbon fines and all sanitation fluid has been removed from the water system.
22. All personnel should be aware of the company requirements for their own
personal health and hygiene.
23. Test for taste before leaving and ensure that the water quality of the machine
is adequate.
Note: To sanitise or descale a machine with a Waterlogic twist filter it is necessary
to mix a solution of either descaler or sanitiser in a dummy filter cartridge to flush
it into the machine. Please ensure no de-scaler enters the cold tank. Please ensure
that no sanitiser enters the hot tank. Santitant and descaler must be flushed into the
machine after by-passing Carbon filter, otherwise the filter will remove the sanitant
or de-scaler being used.
DESCALING A WATERLOGIC MACHINE
1. Turn off the water supply and remove the water inlet pipe.
2. Bypass filters with John Guest pipe and fittings.
3. In a dummy (empty) filter housing, mix the descaler solution as recommended by
the manufacturer.
4. Connect one side of the dummy housing to the machine with a length of 1/4” John
Guest pipe and the other side to the water inlet pipe (check if flow direction applies).
5. Turn water supply back on.
6. Depress hot dispense button and dispense 1 litre of hot water.
7. Leave for 30-40 minutes.
8. Turn off water supply and remove dummy housing.
9. Re-connect water inlet directly to machine.
10. Flush 5-10 litres of water through the machine.
Note: Only use a descaler that is suitable for use in water coolers (citric acid based).

TROUBLESHOOTING
The following faults will be shown on the LCD display should that particular fault
occur.
1. CHANGE FILTER: Please contact your authorised sevice agent.
2. DRIP TRAY FULL: Empty and clean the drip tray.
3. HOT FAULT: Indicates a sensor fault. Please contact your authorised sevice agent.
4. COLD FAULT: Indicates a sensor fault. Please contact your authorised sevice
agent.
5. NO WATER SUPPLY: The pump is running for more than 5 minutes. Check the
water supply in the building. Check water supply to machine.
6. UV FAULT: Please contact your authorised sevice agent.
7. Display not working: check that the unit has been switched on. If the machine is
switched on please contact your authorised service agent.
8. Water is not chilling: Check that the green heater/ compressor switch is on.
9. Water is not heating up: Check that the green heater/ compressor switch is on.
FLOW AND TASTE PROBLEMS
1. No flow of water: Ensure that there is a mains water supply to the machine and
that the machine is turned on. If an anti flood device is fitted to the supply of the
machine, this should be checked to ensure that it has not activated.
2. The hot water is not hot and the cold water is not cold: Make sure that the green
heater/compressor switch at the rear of the machine is turned on.
3. There is flow for the hot water, but not for cold: This may be due to the water in
the cold tank being frozen. Disconnect the power from the machine and leave for
one hour. If the problem persists, please contact you authorised service agent.
4. Low flow of cold water: As above
5. Low flow of hot water: Indicates that the hot tank requires de-scaling. Please
contact you authorised service agent.
6. Low flow for all water circuits: It could be that your filter/filters are blocked.
Please contact you authorised service agent.Waterlogic recommends that filters are
replaced every 6 months.
7. Bad taste: This may occur if the machine is not consistently used. If bad taste
is detected, dispense 5 litres of water into a jug. If the problem persists, please
contact you authorised service agent.
