Thank you for purchasing the Waterlogic WL850HV water purifier.

The WL850HV is suitable for use in a small or large office and it is designed to be

connected to mains public drinking water supplies.

Waterlogic International are using proven technology to clean and then purify your

mains water supply and then chill the water so that you can enjoy great tasting and

healthy still and sparkling water all the time.

Waterlogic uses a unique filtration system containing activated carbon to remove

chlorine and other chemicals from your water supply as well as sediment that have

not been removed by your water authority.

The water is then stored in a double cold tank assembly with choice of cold and

sparkling and also a hot tank providing in total 5.5 litres of stored purified water. The

cold tank contains a specially designed ultra violet light that destroys bacteria and

protects the water from bacteria build-up while in storage.

The WL850HV has been designed in a way that enables ease of service by your

nominated supplier to change both the filter and the UV lamp at 6-month service

intervals.

The WL850HV has new design for the bottle fill solution.

With over 10 years experience in the water industry Waterlogic International Ltd. is

continually developing new products to meet the needs, and health concerns of

businesses and the general public.

If you would like Waterlogic International to keep you informed of the latest

developments in the water industry go to our website at www.waterlogic.com and

Operational Information

WL850 HV

moving of the small switch will allow just the hot button to be pushed to vend

ambient water. This option does allow you to convert the machine for one button

operation for hot water. All machines are factory set at two-button operation for hot

water. Any change of the button configuration for use in hot water dispensing is the

responsibility of the distributor if so required. Waterlogic strongly advises against

the use of a one button operation for a hot water. The PCB also has a UV failure

alarm, and timer switches that can set the UV lamp on time as 3 minutes, 10 minutes

or constant.

COLD TANK

The cold tank is manufactured from 304 Stainless Steel which is non-corrosive,

inert and reflects Ultra Violet Light (UV). The tank system consists of a double

tank assembly. The cold water temperature should be set at 5ºC, this being ideal

temperature for a cold drink. The capacity of the tank is two litres. 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.

UV LAMP

The UV light is an 8watt germicidal lamp at a wavelength of 253.7 NM, which is

very efficient at destroying Bacteria found in water. UV radiation kills 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 also.

The UV lamp can be set to 3 minutes, 10 minutes and constant time on the PCB.

The WL850HV is available

in following options:

a) Cold, Hot & Sparkling

b) Cold, Ambient & Sparkling

c) Cold & Sparkling

When reading this manual,

note the differences between

theoptions and focus on the particular

sections that concern the unit installed.

WL3 Technical Manual - Version 1, October 2012

PCB

The PCB controls the solenoid valves, the pump level probe, the LED power and

warning light. There is also a small switch mounted on the back of the PCB that

will change the function of the hot button. On a hot and cold machine, the hot and

sparkling button must be pushed together for hot water. But on an ambient machine

WL850 HV Technical Manual - Version 1, November 2007

WATER PIPE AND FITTINGS

All water connection fittings are made by the John Guest Company and are approved

to NSF standard 51. The machine is connected the water supply by a ¼” female

bulkhead fitting.

The entire internal water circuit and all the components which come in contact with

water are food grade NSF / WRAS approved.

PLASTIC PANELS

The moulded panels are made from ABS plastic. All the ABS plastic panels are UV

resistant and incorporate the heat retardant standards of CE and UL... Please note

that the machine should not be exposed to direct sunlight. Placing machines in

direct sunlight from a window, or close to a radiator, or on in a room of high ambient

temperature will effect the efficiency of the refrigeration circuit.

WATER PUMP

The pump is 24V DC and forces the pre-chilled cold still water in to carbonation tank

at high pressure. This pressure is required to overcome the internal carbonation

tank pressure of 45 PSI of CO

gas. By forcing cold water at pressure into a tank of

gas the machine produces carbonated water. A level probe in the carbonation

tank controls the water pump connected to the machine PCB.

THE GAS REGULATOR

The correct flow and pressure of gas that is fed to the carbonation tank is controlled

by a CO

gas regulator and is factory set at 45PSI. The gas pressure can be increased

and this may see an increase in the level of carbonation, but this is also relevant

to water temperature and pressure. Over adjustment of gas pressure (50PSI) will

see no increase of carbonation levels and in fact will stop the machine functioning

correctly. Food grade CO

gas must be used at all times.

FILTERS

The filtration system on the WL850HV is NSF approved two –stage filter. Stage

one is a 10 micron screen; Stage two is a Granular Activated Carbon (GAC) process

which will remove a whole range of contaminates e.g. chlorine, pesticides, sediment,

and any taste or odour that may be in the water. Carbon filter also remove a whole

range of other contaminants found in water. 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, and for the exclusion of Crypto, Cysts

and heavy metals. All filters must be changed at 6-month service interval.

HOT TANK

The hot water tank has a two litre capacity; it is manufactured from 304 stainless

steel and is heated by a 800 watt heating element. Temperature of the Hot Tank

is controlled by a mechanical thermostat and is factory set at 87ºC, this being the

ideal temperature for instant drinks. A thermal cut out is fitted to the Hot Tank to

prevent overheating. The tank can be fitted with an optional scale-inhibiting filter

to increase the tank life. Setting the hot water temperature at 87 ºC also helps stop

scale forming in the Hot Tank.

COMPRESSOR

The compressor operates at 220-240V and at 50Hz. It uses R134a non-Ozone

depleting refrigerant gas. There is also the option to use Natural refrigeration gas

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 a customer pushes the dispense

button for a drink. DC voltage is used to give a positive and quieter action of the

solenoid valve. The WL850HV model is fitted with both inlet and outlet valves.

WL850 HV Technical Manual - Version 1, November 2007

Creating Carbonated Water

CARBONATION

The carbonation in the tank has been designed to a similar level to that in international

soft drinks.

Good carbonation depends on a combination of CO

gas pressure, water pressure,

water quality and temperature.

CREATING CARBONATED WATER

Understanding how it works.

Carbonated water is created by mixing carbon dioxide gas with water in a stainless

steel chamber and is controlled by the following parameters:

1. Temperature. The colder the water, the more the gas can be absorbed

2. Water pumping pressure 75 PSI (4.8bar)

3. CO

gas pressure 45 psi (3bar)

Water is pumped into the chamber in the form of a jet which strikes the plate at the

bottom of the tank causing turbulence which in turn causes the gas to be rapidly

absorbed into the water.

Inspection Procedures (PDI)

CAUTION:

Only competent trained technicians should work on Waterlogic products.

Waterlogic units may weigh over 25KG. We recommend caution when lifting.

Packing materials could present a trip hazard. Keep them off the floor.

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.

1. Unpack and carry out a visual inspection of the unit for any transit damage.

2. Remove the top cover and the lower front panel and visually inspect the internals

of the machine for any wires or pipes that may have come loose in transit.

3. Connect the water supply.

4. Ensure the switch on the rear of the machine is in the off position

and connect the unit to a power supply.

5. Connect CO

6. The unit is now live and suitable safety precautions should be taken.

7. Flush water through the hot tank first until the water runs clear of any carbon

fines. Approximately 15 litres.

8. Now flush water through the cold tank. Approximately 5 litres. (20 litres if cold

only)

9. Once you are sure that water is running through both the cooling and heating

circuit

then turn on the heat and compressor switch at the rear of the machine.

10. Carry out a visual inspection for any water leaks.

11. The hot water will heat to approx 87ºC.

12. To test the cold water wait until the compressor has shut off. Extract a further

500 ml of water and allow the compressor to recover again. Test the 2nd cup of

water taken. It should be between 3 and 7ºC.

13. Inspect the cold water produced for clarity and taste. If required flush more

water to remove any adverse taste or carbon fines.

14. Return the switch to the off position and isolate the power and water to the

machine.

Pre Delivery

Inspection Procedures (PDI)

WL850 HV Technical Manual - Version 1, November 2007

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.

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 Meters of the

machine.

4. Remove the top cover of the machine. If you are installing a freestanding machine

also remove the lower front cover. This is retained by two clips located under the

front edge at the bottom of the cover, push clips up to release.

5. Before connecting the CO

bottle to the machine prepare the gas bottle by

removing the dust cover (if fitted). Now 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. Now 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 at 45PSI. Locate

the gas bottle inside the machine and strap the gas bottle to the holder and turn on

the gas. On mini machines, the gas will be located on the outside of the machine.

6. 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 minimum working pressure is 30PSI/2 bar. The ideal pressure is 42

PSI/3bar.

7. Check the electrical socket, and then make the electrical connection to the

machine, 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 before connecting the electrical supply to the machine. Do

not at this stage turn on these switches.

8. The water temperature of the machine is factory set at 5ºC for still/cold water and

87ºC for hot water. Sparkling water will automatically be colder than the still water

as the cold tank system is designed to do this. It is possible to adjust the still water

warmer or colder. It is advised not to adjust the cold water temperature as this could

result in the cold tank freezing, or impairing the quality of the sparkling water.

9. 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.

10. Turn on the Red Power switch at the rear of the machine.

11. Flush 10 litres of water through the hot tank. To do so, depress the hot water

button at the same time as the sparkling button, if installing a hot & cold machine.

The first few litres of water through the machine may have a dark appearance. This

is due to a small amount of carbon being released from the water filter when they

are new. It is harmless and will disappear very quickly whilst you flush the machine.

12. Now depress the cold water button, this will flush water through the still cold

tanks. Flush 5 litres. The sparkling water tank will automatically fill.

13. Check the machine for any water leaks or gas leaks.

14. Once you are satisfied that water is passing through both the hot and cold tank

successfully then turn on the green heater compressor switch. The machine will

now start to heat and chill.

15. The hot water will heat rapidly but it will take about approximately 40 minutes

before the cold temperature reaches its set point.

16. 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.

17. To measure the water temperatures, please ensure that an accurate previously

calibrated thermometer is available.

18. Once the machine has reached the correct temperatures then please ensures

that the cold still and sparkling water produced tastes good. A plastic taste indicates

that the machine needs to be flushed again.

WL850 HV Technical Manual - Version 1, November 2007

19. The sparkling water quality is dependent on the water temperature, and the

water/gas pressure. If the sparkling water is not sharp enough at first, then completely

purge the sparkling tank of water by holding the dark blue button until no more

water comes out of the machine and it starts blowing gas.

Stop pushing the dark blue button and allow the tank to automatically refill and

chill down again. If you do need to make the water colder then please adjust the

thermostat mounted on the rear of the machine in small movements clockwise.

Over adjustment of the thermostat will cause the cold tank to freeze. If you need

to increase the gas pressure then turn the screw adjuster clockwise on the gas

regulator to do this and observe the needle position on the pressure indicator dial

change. The regulator is factory set at 45 PSI. Adjustment of the gas pressure over

50 PSI could impair the quality of the sparkling water and stop the correct function

of the machine.

20. If required by local health and safety guidelines test the machine to make sure

it is electrically safe.

Maintenance and Servicing

1. Every six months it is strongly recommended that the filters and UV lamp be

changed. If the model of machine is hot and cold, the hot tank may require any

build up of Calcium to be removed. The need to remove calcium from the hot tank

depends on local water conditions and the flow of water from the hot tank being

restricted.

2. To carry out the service you will need to switch off the red and the green switch

at the back of the machine and remove the machine top cover and lower front cover,

if the machine is free standing.

3. Remember there is no need to turn off the water with a Waterlogic Twist Filter; the

water is automatically isolated when you remove the filter.

4. The filter is located on the lower part of a freestanding machine behind the lower

front cover. On a mini machine the filter is under the top cover. Remove the filter

by gripping the filter head and twisting the filter body by hand clockwise (left-hand

thread).

5. Replace with a new Twist Filter.

6. Make sure you turn off the red switch at the back of the machine to isolate the

electrical power.

7. Remove the UV lamp by unplugging the UV loom connector and pulling the

lamp upward, then unscrewing the UV retaining nut located on the top shelf of both

models, and remove the Quartz Sleeve from the cold tank. Clean the Quartz Sleeve

and remove any surface lime scale that may have adhered to the sleeve surface.

Check the black O Ring for signs of perishing and change if necessary.

8. Fit the Quartz Sleeve back into the cold tank taking great care at this stage not to

crack the Quartz Sleeve by over tightening the UV retaining nut.

9. Inspect the UV loom if it shows signs of discolouration or wear, replace it.

Assemble the UV loom onto a new UV lamp and fit into the quartz sleeve. Do not

touch the UV lamp.

10. Inspect the blue faucet nipple and if it is cracked or has Calcium build up, replace

it. Please ensure that you use cleaning gloves when handling parts that come in

direct contact with the water.

11. Clean the Condenser Grill and Compressor of any dirt build up.

12. Check the air gap around the machine is not blocked.

13. Turn on the power supply and make sure only the red switch on the rear of the

machine in the on position.

14. Flush five litres of hot water (if a hot & cold machine), 5 litres of cold water and

one litre of carbonated water through the machine to ensure that the filters are

generated and the water is running clear of any carbon fines.

15. Purge the CO2 gas by lifting the yellow pressure release lever for 3 seconds.

16. Make sure that the UV lamp is alight by observing a blue glow from the top of

the UV cap. Do not remove the lamp from holder whilst ignited and do not look into

a naked UV light.

17. Inspect the water and electrical connections visually.

18. Turn on the green switch and allow the machine to cool and heat the water.

19. Check the machine is clean and functions to the customer’s satisfaction.

WL850 HV Technical Manual - Version 1, November 2007

TROUBLESHOOTING THE WL850HV

1. No Cold Water Flowing: There are a number of reasons that could be causing this

problem. 1) Check if the water in the building is turned off! 2) Check if the isolating

valve has been turned off! 3) Check if the filter blocked with sediments or passed

its change date! 4) Check if the solenoid valves are operating! 5) Check if the cold

tank has frozen. 6) Check if the red LED warning light is flashing!

2. Water Flows but is Not Cold: 1) Check that the compressor switch at the rear

of the machine is turned on. 2) Have you just taken more than 3 jugs of water?

The machine takes about 30 min to recover temperature after heave use. 3) Is the

machine sited in an area with an ambient room temperature in excess of 30°C. 4)

Does the machine have a 5cm air gap around it? 5) Test the machine cooling system

for loose of refrigeration gas. If the compressor is continually running hot and mot

making cold water, then this could mean it need gas. Check the compressor to

ensure it is running. Make sure the thermostat is adjusted correctly.

3. Water has a Plastic or Funny Taste: 1) If the machine is new it may need to be

flushed. 2) Has the machine been unused over a long weekend? Then flush 5 litres of

water before using. 3) Fit a new filter if it has passed its changing date. 4) Contact you

local dealer if adverse local water conditions are causing taste problems.

4. Restricted or Slow flow of cold or sparkling water: 1) Check that the water

supply is above 1.5 bar or 21 PSI, as the machine will not function correctly below

this! 2) Check that the gas bottle is not empty. 3) Check that the filter is not blocked

or past its changing date. 4) Check that the faucet is not blocked.

5. Vend buttons sticking:

1) this fault is caused by dirt or cleaning material filling

the gap around the button. Do not use cream or abrasive surface cleaner.

6. Red LED Warning Light flashing: 1) the pump has been running too long and

has timed out. Please check the water supply to the pump. Te reset the pump turn

the power on and off to the machine.

7. Machine no Power: 1) check that the machine switches are on the back of the

machine. 2) Isolate the power supply and check the machine fuse. 3) Check that the

power cord is plugged into the back of the machine and is pushed home. 4) Check

that the power cord is plugged into the wall socket and is switched on. 5) Check that

there is no problem with the building electrical supply.

8. No Hot Water: 1) Make sure the heater switch is on at the rear of the machine. 2)

Does the hot tank need to be de-scaled? 3) Check the power supply to the heating

element. 4) Disconnect the power and check the resistance of the heating element.

5) Is the water supply to the machine turned on? 6) Are the solenoid valves operating

correctly? 7) Is the filter blocked or past its change by date?

9. Factory sets the cold water at 5°C. Waterlogic strongly advice that you do not

adjust the water to a colder temperature. Care should be taken if the thermostat is

adjusted colder as this could increase the risk of the cold tank freezing. It is advised

that any adjustment to the thermostat to male the water colder be done in small

turns of the thermostat of a few degrees at a time. Allow the compressor to cycle on

and off, check that the temperature is as required before any further adjustment. In

the event that the cold tank should freeze then please turn the compressor switch

mounted at the rear of the machine to the off position. Allow the machine to stand

for one hour. Flush 1 litre of water through the machine, adjust the thermostat back

to the factory position set point as marked and turn the compressor switch back on.
