Machine Overview
WL Max
ICE BANK TECHNOLOGY
The WL Max is available in the following options:
a) Cold Only Single Faucet (High Capacity)
b) Cold Only Double Faucet (High Capacity)
The ice bank technology system is manufactured from 304 Stainless Steel which
is non-corrosive and inert. The cold water temperature is preset at the factory at
approximately 5 degrees C, this being the ideal temperature for a cold drink.
The ice bank technology system, unlike other reservoir systems, reduces the amount
of water stored in the machine. The capacity of the coil system is 18cl.
FILTERS
The filtration system on the WL Max is 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.
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 13 watt 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 or when indicated
by the warning lights, and the quartz spiral may need to be cleaned by using an
ultrasonic bath.
PCB
The PCB (Printed Circuit Board) is the control unit for the WL Max; it is responsible
for the functions of all the mechanical and electrical parts (24V DC) including the
solenoid valves.
COMPRESSOR
The compressor operates at 220-240V at 50Hz or 120V at 60Hz. It uses 165g of
R134a non-Ozone depleting refrigerant gas.
WATER PIPES AND FITTINGS
The inlet and the internal water circuit pipe size is 1/4”. The entire internal water
circuit and all the components which come in contact with water are food grade
NSF approved.
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 activates the
dispense button for a drink. DC voltage is used to give a positive and quieter action
of the solenoid valve.
DRAIN
The WL Max drip tray has a drain feature which requires a connection to a container/
waste.

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.
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 flat surface.
3. Open the top and bottom covers by removing the screws that fix them in place.
4. Visually inspect all electrical connections and power lead.
5. Visually inspect all water connections.
6. Remove the top cover from the Firewall Housing and inspect the quartz spiral
for damage. If all is ok then re-assemble.
7. Connect to a potable drinking water supply via a 1/4” John Guest tube, the supply must be limited to 3bar.
8. Connect the power cord to an appropriate power supply and the machine.
9. Replace all the panels and re-fit the screws.
10. Select the cold dispense button until water flows clearly from the faucet.
11. When the ice bank reservoir has been filled, turn on the compressor switch.
Allow up to two hours for the unit to heat and chill. Test water temperatures and
ensure the water tastes acceptable.
12. Check all functions of the WL Max.

Installation Procedures
1. Mount the WL Max 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 WL Max 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.
2. Level the machine using the adjustable feet if needed.
3. 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.
4. Remove the top and bottom covers of the machine. Inspect all water and electrical and water connections to make sure they have not come loose whilst in transit.
5. 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)
6. Remove the cap from the top of the WL Max Ice Bank reservoir and place to one
side.
7. Insert your water feed into the top of the Ice Bank reservoir and fill the reservoir
until the water level is 2mm away from the top.
8. Replace the cap on the top of the reservoir.
9. 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 WL Max.
10. Check all the connections to ensure there are no water leaks within the WL Max
machine.
11. Re-fit the top and bottom covers and secure them using the screws removed
earlier.
12. Check the electrical wall socket (polarity) and then make the electrical connection to the WL Max by plugging the power lead into the socket on the rear of the WL
Max. Then connect it to the electrical feed or wall power outlet. Turn on the power
supply to the WL Max.
13. Depress the dispense button and flush through 10 litres of water. When the reservoir is full turn on the red switch at the rear of the machine. The machine will now
begin to cool.
14. The water temperature is pre-set at the factory to 5°c.
15. 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.
16. The WL Max should be sanitized at installation. A suitable sanitizer such as Aqua
Dosa should be used.

Maintenance and Servicing
• Every six months or every 6 000 UV lamp cycles we strongly recommended
that the UV lamp be changed.
• Every six months or after 10 000 litres it is strongly recommended that the
filter be changed.
• The Firewall quartz spiral needs to be removed, inspected and cleaned
where necessary.
• No paperwork or cleaning records should be stored inside the WL Max.
Items Required for the 6 Month Service Procedure
• Rubber Gloves
• Phillips/ Cross head screwdriver
• Replacement filter cartridge
- CBC cartridge part number: FT-0036
• Replacement UV lamp
- UV lamp part number: CT-2085
• Aqua Dosa (or similar) sanitizing fluid
• Peroxide test strips
• A container that can hold 5 litres
• Non-abrasive anti-bacterial wipe or cloth
SERVICING PROCEDURE
1. Put on the rubber gloves to minimise the chance of any contamination to the
machine and to protect yourself whilst the servicing procedure is being carried out
2. 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 dispense
button until water stops dispensing
3. Isolate the power to the WL Max by turning off the red power switch at the rear
of the machine and completely removing the power lead
4. The filter is located in the WL Max base cabinet behind the lower back panel
5. 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 CBC carbon cartridge. The
cartridge can then be removed from the filter housing and replaced by a new one
6. The new filter cartridge will require flushing prior to being re-fitted into the WL
Max. 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 allow 10 litres of water to pass through the filter, to ensure
that any loose carbon fines are fully removed to avoid any damage being caused
to the machine and to sufficiently generate the new filter cartridge
7. After the filter has been flushed it can be replaced in the WL Max and the water
pipes can be reconnected
8. Remove the UV lamp by unplugging the UV loom connector and pulling the
lamp upwards. Then remove the top cover from the Firewall housing and remove
the quartz spiral
9. Check the spiral for any scale build up and clean were necessary
10. Replace the quartz spiral into the Firewall housing and insert the new UV
lamp assembly making sure not to touch the new UV lamp with bare hands as this
will shorten the life of the lamp. Connect the UV lamp connector and replace the
Firewall housing top cover
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 lead and insert it into the rear of the machine
16. Flush through 5 litres cold 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 litres of water until you are satisfied with the taste
17. The red compressor switch can now be turned on, allow the machine to 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 the water.

SANITISING
1. Put on the rubber gloves to minimise the chance of any contamination to the
machine and to protect yourself whilst the servicing procedure is being carried
out.
2. 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 dispense
button until the water stops dispensing.
3. Isolate the power to the WL Max by turning off the red power switch at the rear
of the machine and completely removing the power lead.
4. The filter is located in the WL Max base cabinet behind the lower back panel;
you will need to remove this panel to access the filter.
5. To remove 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 CBC carbon cartridge. The
cartridge can then be removed from the filter housing, put this to one side as you
will need it again later.
6. Add the required amount of sanitisation fluid (e.g. Aqua Dosa) to the empty
filter housing and screw the filter body to the filter head, making sure it’s securely
tightened.
7. Fit the filter assembly with the sanitisation fluid into the machine and reconnect
the water pipes into the elbow fittings.
8. Replace the lower back panel and fix it in place with the screws you removed
earlier.
9. The water supply to the machine can now be turned on.
10. Reconnect the power lead and insert it into the rear of the machine.
11. Dispense cold water until the sanitisation fluid leaves the faucet. Whilst you are
dispensing the cold water hold a peroxide test strip under the dispense area and
test the flow of water to check that the sanitisation fluid is present in the ice bank
coil.
12. Leave the sanitisation fluid to stand in the ice bank coil for 20 minutes. Once
this time has passed select the dispense button and then select the dispense
button and flush enough water to remove the sanitisation fluid from the machine
(usually about 10 litres). Use the same method as before and check all the
sanitisation fluid has left the tank by using a peroxide test strip.
13. Turn off the water supply at the isolation point.
14. Select the dispense button until no more water is being dispensed.
15. Completely remove the power lead from the unit.
16. Remove the lower back panel from the WL Max and disconnect the water
pipes from the elbow fittings on top of the filter. Remove the filter from the
retaining bracket and unscrew the filter body from the filter head by turning the
base in an anti-clockwise direction.
17. Pour away the excess water and re-fit the filter cartridge to the filter head,
making sure it firmly and securely fitted. Screw the filter body to the filter head so
it is securely tightened.
18. Re-fit the filter into the retaining bracket and re-connect the water pipes into
the elbow fittings.
19. Replace the lower back panel and fix it in place with the screws you removed
earlier.
20. The water supply to the machine can now be turned on.
21. Reconnect the power lead and insert it into the rear of the machine.
22. The red compressor switch can now be turned on, allow the machine to cool
the water.
23. Clean the outside of the machine with a non-abrasive anti-bacterial wipe or

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.
1. No flow of water: Ensure that there is a water supply to the WL Max 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. Waterlogic recommend filters are changed at 6 months.
3. The cold water is not cold: Make sure the compressor switch is turned on.
4. The cold water is not flowing: This may be due to the cold water reservoir
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 reservoir is not frozen then check the solenoid valves are
operating correctly and being turned on and off when you push the dispense
button.
5. Low flow of cold water: Check the building water pressure to the WL Max is
45 PSI. Check the filters are not partially blocked, and that the solenoid valves
function correctly, check if cold reservoir ice buildup needs to be defrosted.
6. Bad or plastic taste: If the WL Max is new it may need flushing for a longer
period, make sure the machine has been sanitized at installation.
7. Water leaks: Most leaks will trip the Waterlogic block located on the installation
kit. Should you see water leaking from the WL Max, isolate the supply and start
normal fault finding procedures.
8. No power: Check the building electrical supply to the WL Max is on and that
the power cord is plugged in. Test the WL Max fuse. Check that the top. If all these
points are OK then start normal fault finding procedures.
