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.

WL3 Technical Manual - Version 1, July 2014

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

Cylinder & Gas Regulator: The units with the option of sparkling water will

need CO

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

). The gas regulator, which comes with the unit, controls the flow of CO

to the

carbonation tank; it reduces the pressure of the CO

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

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.

Take care not to allow the power lead to get wet. If the lead gets wet it must not

be used.

gas cylinders used for sparkling units are under high pressure and should

be handled carefully and all safety instructions should be followed.

For Hot and Cold units, omit section 8, 10, 12.

For Cold and Sparkling units, omit section 13, 15.

WL3 Technical Manual - Version 1, July 2014

14 15

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

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

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

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

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

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

pressure

regulator. Attach the CO

pressure regulator to the CO

cylinder and then attach to

the WL3 Firewall CO

‘IN’ bulkhead connector using 1/4” flexible pipe. Turn on the

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

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

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

cylinder and disconnect the CO

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

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

pressure regulator

when it has been removed from the empty CO

cylinder. If it is still correctly in place

then attach the CO

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

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

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

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

back on following

this procedure. (DO NOT LEAVE THE MACHINE WITHOUT CHECKING THE CO

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:

•AnemptyWaterlogicinlinefilterhousing

•Rubbergloves

•Antibacterialwipesorspray

•Teststrips

•Acrossheadscrewdriver

•Sanitisationfluid

•Acontainer

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.

PROTECTION LED

BioCote protection is active.
