Machine Overview
WL3 FIREWALL
SPARKLING COLD TANK
The sparkling tank is manufactured from 304 Stainless Steel which is noncorrosive.
The temperature of the sparkling tank is set to 5°C. The capacity of the tank is 1.8
liters.
HOT TANK
The hot water temperature is controlled by a Microprocessor and is set to 87°C for
standard and 93°C for extra hot.(Extra hot is only available on selected models) A
thermal cut out is fitted to the Hot Tank to prevent overheating. The tank is fed water
via a polyphosphate filter to increase the tank life and to reduce the risk of scale
build up. Setting the hot water temperature at 87°C also helps stop scale forming in
the hot tank, prolonging the 800Watt element and the Hot Tank. Please note that
the extra hot feature is not available on machines with sparkling water.
FILTERS
The filtration systems on the WL3 are 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. It is important for the UV
sterilization system to be supplied with clean water in order to achieve maximum
efficiency. There are many kinds of different filter combinations available from
Waterlogic to suit local water conditions.
FIREWALL CHAMBER
The Firewall chamber incorporates the in-Faucet UV and is made of aluminium and
is highly reflective. The Chamber houses the UV lamp and quarts spiral as well as
the faucet.
The WL3 Firewall is available
in the following options:
a) Cold, Hot & Sparkling (Full Option)
b) Cold, Hot & Ambient
c) Cold & Ambient
d) Cold, Ambient & Sparkling
When reading this manual, note the differences
between the options and focus on the particular
sections that concern the unit installed.
COLD TANK
The cold tank is manufactured from 304 Stainless Steel which is noncorrosive
and inert. The temperature of the Cold Tank is controlled by a electro-mechanical
thermostat and is set to 5°C, this being ideal temperature for a cold drink. The
capacity of the cold tank is 4 liters and 2 liters depending on the model.

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 touches the
dispense button for a drink. DC voltage is used to give a positive and quieter action
of the solenoid valve.
PLASTIC PANELS
The molded 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 WL3
should not be exposed to direct sunlight. Placing the WL3 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
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 3bar which is needed to
make high quality sparkling water.
Water Pump: The water pump is 24V DC and forces the pre-chilled cold still water
into the carbonation tank at a minimum pressure of 3.2 bar. This pressure is required
to overcome the internal pressure from the CO
2
gas which is in the tank.
IN FAUCET UV
The Unique design allows the faucet area to be sterilized before, during and after
every dispense. There are two types of sensors available, the CDS UV sensor that
detects if the UV lamp is working and the UV sensor that monitors the UVC intensity
from the UV lamp.
UV LAMP
The UV light is a 13Watt 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 Firewall
Chamber surrounded by a quartz spiral that attains NSF standard 55 purification of
water. The UV lamp must be replaced at 6 months intervals, and the quartz spiral
cleaned by using an ultrasonic bath if needed.
PCB
The PCB (Printed Circuit Board) is the control unit for the WL3, it is responsible
for the functions of all the mechanical and electrical parts (24V DC) including the
solenoid valves, touch panel, LED’s and pump.
COMPRESSOR
The compressor operates at 220-240V at 50Hz. It uses 60-72 grams of R134a non-
Ozone depleting refrigerant gas depending on the model type.
WATER PIPES AND FITTINGS
The inlet and the internal water circuit pipe size is 1/4” and 5/16”. The entire internal
water circuit and all the components which come in contact with water are food
grade NSF approved. The Cold, Ambient and Sparkling water tubing inside the
machine should not be exposed to water above 25˚C.

1. Remove packing straps and unpack unit and visually inspect for any damage.
(Report any defects to Waterlogic as soon as possible).
2. Place the unit on a suitable work bench or leave on the floor for free standing
models.
3. Open the top cover by removing the two screws that fix it in place.
4. Visually inspect all electrical connections and power lead.
5. Visually inspect all water connections.
6. Remove the three screws on top of the Firewall Chamber and inspect the quartz
spiral for damage and re-assemble.
7. Connect to a potable drinking water supply via a 1/4” John Guest tube,
the supply must be limited to 3 bar.
8. Connect to a CO
2
gas regulator via a 1/4” John Guest tube and set to 3 bar.
9. Connect the power cord to an appropriate power supply and the machine.
10. Turn the CO
2
on and lift the yellow safety valve for 5 seconds.
11. Replace the top cover and re-fit the screws.
12. Once the power, water and CO
2
are all turned on the unit will auto fill the sparkling
water tank.
13. Note that if the machine has a hot option, the hot tank must be filled before any
other tank.
14. Select the hot + extra hot button until water flows clearly.
15. Select the cold button until water flows clearly.
16. After cold/hot has filled, turn on heater/compressor switch allow up to an hour
for the unit to heat and chill. Test water temperatures and ensure the water tastes
acceptable.
17. Check all WL3 functions.
18. Turn off power, water and CO
2
if a sparkling unit.
19. Turn unit around and drain from rear drain valves if fitted.
20. Clean and repack ready for dispatch.
21. Waterlogic recommend that all units are fully electrically (PAT) tested on site by
the commissioning engineer as damage may have occurred during transit to the
unit’s final destination.
Installation Procedures
1. Check and assemble the WL3 base cabinet if required to do so.
2. Mount the WL3 Firewall on a firm, level surface so the machine cannot topple or
fall over. A 50mm air gap is required the whole way around the machine to allow for
sufficient ventilation. The WL3 must not be installed in direct sunlight, adjacent to a
heat source, or in an ambient room where the temperature is above 30°C or below
5°C.
3. Level the machine using the adjustable feet if needed.
4. It is advisable to have the power and water supply within a 2 metre range of
the machine, the isolation for the water and electricity should be easily accessible.
The supply of water must be from a potable source and the machine should not be
installed using an extension lead.
5. Remove the top cover of the machine. If you are installing a freestanding machine
also remove the lower base cover. This is retained by two screws located under the
front edge at the bottom of the cover and two clips in the same location. Remove
the screws and push clips up to release it. Inspect all water and electrical and water
connections to make sure they have not come loose whilst in transit.
6. If you are installing a carbonated machine then please follow this step, if not
proceed to step 7. Prepare the CO
2
cylinder first by removing the dust cap (if there
is one in place), then face the cylinder away from you and purge some of the gas for
two seconds to clear any dust or dirt from the nozzle prior to fitting the CO
2
pressure
regulator. Attach the CO
2
pressure regulator to the CO
2
cylinder and then attach to
the WL3 Firewall CO
2
‘IN’ bulkhead connector using 1/4” flexible pipe. Turn on the
CO
2
gas bottle. The pressure regulator should be pre-set at 45 PSI (3 bar). If the
pressure reading is higher or lower than 45 PSI, then please adjust it to the correct
setting. The CO
2
bottle should be secured inside the base cabinet, or secured within
a cabinet adjacent to the WL3 Firewall, so the cylinder cannot fall over.
7. Remove the inline filter from the machine and attach a water feed directly into
the inlet side, attach another length of water pipe to the outlet side and direct this
into a bucket or a large container. Allow 10 litres of water to pass through the filter
clearing any carbon fines that may need to be flushed out. (This process may need
to be repeated).

8. Make the water connection using an installation kit. Waterlogic recommends the
use of a pressure reducing valve, a shut off valve and a non return valve. These
should be fitted before the water intake to the machine. Minimum operating pressure
for the machine to work suitably is 2.6bar. The minimum incoming flow rate is 1.2
litres per minute. The ideal operating pressure is at 3bar, and at pressures higher
than 3.2bar the machine will not function correctly and this can lead to leaks. The
water should be from a potable source and should be allowed to run clear of any
sediment before making the connection into the WL3 Firewall.
9. Check all the connections to ensure there are no water or CO
2
leaks within the
WL3 Firewall machine.
10. Check the electrical wall socket (polarity) and then make the electrical connection
to the WL3 by plugging the power lead into the socket on the rear of the WL3. Then
connect it to the electrical feed or wall power outlet. Turn on the power supply to
the WL3.
11. Re-fit the top and bottom covers and secure them using the screws removed
earlier, then turn on the red power switch. The WL3 will go through a self-test
cycle and the LED’s will light automatically. When the self-test cycle completes, the
sparkling water model will automatically fill with water, whilst still water models will
need to be manually flushed by depressing the hot dispense button first or the cold
water dispense button. When the WL3 has completed filling flush through 10 litres
of water by depressing the hot, cold and sparkling buttons. Make sure the hot tank
is full of water and turn on the green heater and compressor switch at the rear of the
machine, the WL3 Firewall will then begin to cool and heat.
12. The water temperatures are pre-set at the factory to 5°c for the cold water and
87°c for the hot water.
13. The water should now be taste tested, any hint of a taste in the water means
the machine needs to be flushed further with an additional 10 litres and then taste
tested again.
14. The WL3 Firewall should be sanitized at installation.
1. Turn off the empty CO
2
cylinder and disconnect the CO
2
pressure regulator.
2. With the new bottle, remove the dust cap (if there is one in place), aiming the
valve away from you. Momentarily open the valve and purge some of the CO
2
gas
to remove any dirt or dust that may have entered the nozzle.
3. Check that the rubber O-ring has not fallen out of the CO
2
pressure regulator
when it has been removed from the empty CO
2
cylinder. If it is still correctly in place
then attach the CO
2
pressure regulator to the new bottle and connect via a length
of ¼” flexible hose to the WL3 Firewall.
4. Open the valve slowly simultaneously with step 5 below and observe the gauge
reading on the regulator, it should be at 3bar of pressure as this setting is pre-set,
but if not adjust were necessary.
5. Lift the yellow lever under top cover for 4-6 seconds to purge the gas line and
carbonator.(This must be done when you open the CO
2
cylinder valve so that the
tank is not damaged when initially pressured)
6. Place a container of at least 5 litres under the faucet and dispense sparkling
water until just the CO
2
gas is being dispensed from the faucet. The WL3 will now
refill. This takes approximately 4 minutes. When the pump has stopped turn the CO
2
gas bottle off.
7. Record the regulator pressure, normally 3 Bar. After 5 minutes check the gauge
for any pressure drop as this indicates a leak and turn the CO
2
back on following
this procedure. (DO NOT LEAVE THE MACHINE WITHOUT CHECKING THE CO
2
IS
SWITCHED ON!!!)

1. You will need to stop the water supply to the machine by turning the isolation
valve to the off position and releasing the pressure by depressing the cold water
button until the water stops being dispensed.
2. Isolate the power to the WL3 Firewall by turning the red and green power
switches off, these are located at the rear of the machine. Remove the power lead
as a second safety precaution.
3. The filter is located in the WL3 Firewall base cabinet behind the lower front panel
or within the top front panel if it is a mini model.
4. To replace the filter detach the water pipes from the elbow fittings at the top,
then the filter can then be removed from the retaining bracket. Unscrew the filter
housing by twisting it clockwise, this will expose the carbon cartridge. The cartridge
can then be removed from the filter housing and replaced.
5. The new filter will require flushing prior to being re-fitted in the WL3 Firewall.
To do this connect a water feed directly into the inlet side of the filter and attach
another length of pipe to the outlet side and direct this into a bucket/large container
or drain, then flush through 10 litres of water to ensure that any loose carbon fines
are fully removed from the filter to avoid any damage being caused to the machine.
6. After the filter has been flushed it can be replaced in the WL3 Firewall and the
water pipes can be reconnected.
7. Remove the UV lamp by unplugging the UV loom connector and pulling the lamp
upwards. Then undo the three screws and remove the top cover of the Firewall
housing and the quartz spiral.
8. Check the spiral for any scale build up and clean were necessary.
9. Examine the UV loom for any discolouration or wear, if there is any visible remove
the loom and replace with a new one.
10. Replace the quartz spiral and reconnect and replace the UV lamp assembly and
Firewall housing, making sure not to touch the new UV lamp with bare hands as this
will shorten the life of the lamp.
11. Inspect all of the electrical and water connections on the machine, and take any
action necessary to prevent a fault from occurring.
12. Check the faucet nipple for any calcium build up or any visible damage and
clean or replace it if necessary.
13. Reassemble the machine and secure all panels with screws.
14. Check that the air gap around the machine is sufficient and there is nothing
blocking the ventilation.
15. Reconnect the power to the machine and turn the red switch at the rear of the
machine to the ‘on’ position.
16. Flush through 5 litres of hot and cold water and if there is the option, 5 litres of
sparkling water to ensure the water is running clear of any carbon fines and that the
taste of the water is clean and to the customers satisfaction. If you are not happy
with the quality of the water continue to flush an additional 2-5 litre of water until
you are satisfied with the taste.
17. The green heater and compressor switch can now be turned on, allow the
machine to heat and cool the water.
18. Clean the outside of the machine with a non-abrasive anti-bacterial wipe or
cloth.
19. Taste the water one final time and check it is cooling and heating the water.
SANITISING
You will need the following items:
•AnemptyWaterlogicinlinefilterhousing
•Rubbergloves
•Antibacterialwipesorspray
•Teststrips
•Acrossheadscrewdriver
•Sanitisationfluid
•Acontainer
1. Put on the rubber gloves to minimise the chance of any contamination to the
machine and to protect yourself whilst the sanitisation procedure is being carried out.
2. Turn off the water supply to the machine and release the internal pressure by
pushing the cold button until the cold water stops being dispensed. Then disconnect
the water feed pipe from the bulkhead at the rear of the machine.
WL3 Technical Manual - Version 1, July 2014
24 25
3. Measure 45ml of Aqua Dosa sanitising fluid into the empty filter housing and
securely fasten the filter head.
4. Insert the water feed pipe into the inlet fitting of the inline filter housing containing
sanitisation fluid. Attach a length of ¼” water pipe into the outlet fitting and insert
the other end of the pipe into the bulkhead at the rear of the machine.
5. Remove the filter cartridge from the filter inside of the machine to avoid the
mixing of sanitisation fluid and the active carbon, reattach the filter head securely.
(The filter head can also be bypassed during sanitisation)
6. The water supply to the machine can now be turned on.
7. Dispense cold water until the sanitisation fluid leaves the faucet, this can be
checked by pressing the cold button until the colour of the test strip has changed to
indicate the presence of the Sani fluid (Normally about 400-500ml of water needs
to be dispensed). If the machine has a carbonated option depress the cold button
until 200ml of water has been dispensed and then depress the carbonated button
and dispense the same amount of water, use the test strips to ensure the sanitisation
fluid has reached the cold and the sparkling tanks. Do not let any sanitisation fluid
enter the hot tank.
8. Leave the sanitisation fluid inside the machine for a minimum of 10-15 minutes,
when this time has been reached, flush water through the machine until there is
no sanitisation fluid left inside. Fit a new filter cartridge into the internal filter and
remove the empty filter housing from the back of the machine, connect the water
feed pipe directly into the bulkhead and turn the water supply on.
9. Inspect the faucet nipple and clean or replace if it is damaged or if there is a
calcium build up around it.
10. Isolate power to the machine, then remove the quartz spiral by undoing the
three screws on the top of the Firewall housing, disconnecting the UV sensor and
water pipe, and removing the UV lamp. Inspect the spiral for any damage or calcium
build up, if there is a large amount of calcium remove and replace the spiral and
send it away to be treated by an ultrasonic bath.
11. Using the antibacterial wipes, sufficiently clean the exterior panels of the machine,
including the drip tray and grill.
DE-SCALING
You will need the following items to descale the hot tank.
•A container that can hold 5 litres of water
•Funnel or squeeze bottle
•Syringe
•Star/Phillips screwdriver
•Descaling solution
1. Allow the machine to heat the water up to normal operating temperature, as the
water inside the tank needs to be hot for the descaling solution to work effectively
(Scale Kleen)
2. Isolate the power by disconnecting the power lead at the rear of the machine.
Remove the top cover from the machine by undoing the two screws at the back of
the lid and lift the panel in an upward motion.
3. Disconnect the silicone tubing from the faucet nipple, leave the other end attached
to the outlet at the top of the hot tank.
4. Drain 50-100ml of hot water from the machine into a container, using the drainage
valve at the rear of the machine. Then use the hot water from the machine to make
your descaling solution, following the manufacturer’s instructions of the descaler.
5. If you are using a syringe then draw up the solution into the syringe and insert
it into the open end of the silicone tubing, this should be done slowly as doing this
process too quickly can result in the tank overflowing. If doing this with a funnel use
the same process except you will pour the solution into the funnel connected to the
silicone tube, add the solution in stages to prevent the hot tank overflowing.
6. Allow the solution to remain in the tank for 5 – 10 minutes, re-attach the silicone
tubing to the faucet nipple, replace the top cover and then re-connect the power
lead, and flush through the hot tank by dispensing water from the hot option. You
will need to flush approx. 4-8 litres of water.
7. Open the top cover and check for leaks and then replace the top cover and
secure it using the two screws
8. Smell and then taste the water and flush more water through the tank if needed.

FAULT FINDING
All fault finding procedures must be carried by a technician trained by Waterlogic
International or their nominated distributor. Please take great care and suitable
health and safety measures when fault finding on live electrical parts.
ADVISORY ICONS
1. No flow of water: Ensure that there is a water supply to the WL3 Firewall from
the building and that the installation isolation valve is turned on. If the installation kit
has an anti-leak device included in it (as Waterlogic Installation kit) then make sure
it has not tripped.
2. No flow of water: Check that the water filters are not blocked and that they are
in date and are screwed home securely into the filter head. Waterlogic recommend
filters are changed at 6 months.
3. The hot water is not hot and cold water is not cold: Make sure the green heater
compressor switch is turned on.
4. There is hot water flow but cold water is not flowing: This may be due to the
cold water tank being frozen. If so disconnect power supply for one hour to allow
the tank to defrost, and then flush the cold water system. Check the temperature
settings are correct. If the cold tank is not frozen then check the solenoid valve is
operating correctly and being turned on and off when you push the cold button.
5. There is cold water flow but hot water is not flowing:
This may be due to
calcium build up in the hot tank or the hot water outlet. De-scale the hot tank. Check
the hot water solenoid valve functions correctly and turns on and off when you hold
the hot and extra hot buttons together for 3 seconds.
6. Low flow of cold water or hot water or both: Check the building water pressure
to the WL3 Firewall is 45 PSI. Check the filters are not partially blocked, that the
solenoid valves function correctly, hot tank calcium build up need to be de-scaled,
cold tank ice build up needs to be defrosted.
7. No sparkling water: Ensure the CO2 bottle is full and turned on and set at 45
PSI. Turning the gas pressure above 45 PSI can stop the production of sparkling
water. Check the pump Icon. If flashing turn off the power to the WL3 Firewall for 1
minute and then back on to reset the carbonation pump. The pump will time out if it
runs for more than 8 minutes continuously.
8. Bad or plastic taste: If the WL3 Firewall is new it may need flushing for a longer
period.
9. Water leaks: Most leaks will trip the Waterlogic block located on the installation
kit. Should you see water leaking from the WL3, isolate the supply and start normal
fault finding procedures.
10. No power: Check the building electrical supply to the WL3 Firewall is on and
that the power cord is plugged in. Ensure the red power switch at the rear of the
WL3 Firewall is on. Test the WL3 Firewall fuse. If all these points are OK then start
normal fault finding procedures.
11. All Icons flashing and audible alarm: An over heat fault has been detected
please switch the WL3 Firewall off immediately and start fault finding procedures.
POWER LED
This LED shows the machine is connected to mains power and is switched on
and live. If this led icon is continuously flashing, this indicates a No Water Supply
fault. Check the water supply is turned on; if the fault persists please call your
authorised service agent.
FILTRATION LED
Filtration is Active.
PURIFICATION LED
This led shows the UV lamp is operating correctly. Should this icon be continuously
flashing and the machine not dispensing water, then this indicates a UV fault.
Please call your authorised service agent.
