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.

WL3000 Technical Manual - April 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 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

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

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

). 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 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

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

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

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.

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.

BIOCOTE® ANTIMICROBIAL SOLUTION

For your added protection this product incorporates BioCote® antimicrobial tech-

nology. Silver, in the form of silver ions, is the active ingredient utilised in BioCote®.

This silver technology is manufactured into the surface of our products, giving them

built-in sustainable antimicrobial protection. BioCote’s silver technology has been

tested by an independent laboratory to show its ability to inhibit the growth of bac-

teria, mould and fungi by up to 99.9% over a 24 hour period and for the duration of

the machine life.

FREQUENTLY ASKED QUESTIONS ABOUT BIOCOTE®:

Why use BioCote®? BioCote® will help reduce the risk of cross-contamination. You

may not want to think about it, but every surface in the working environment is a

potential breeding ground for Bacteria.

How is it applied? BioCote® is applied via an additive into the manufacturing pro-

cess and will, therefore, be present throughout the moulded or painted parts.

How long will BioCote® last? BioCote® will last for the usual life expectancy of

your water dispenser. It will not wear or wash out with use or cleaning.

What bacteria is BioCote® effective against? BioCote® is effective against most

common bacteria, moulds and fungi.
