• Replacement filter cartridge
- CBC cartridge part number: FT-0036

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.
