Maintenance And Servicing - WaterLogic WL3 Firewall Technical Manual

Maintenance and Servicing

• Every six months it is strongly recommended that the UV lamp and filters be
changed.
• The Firewall quartz spiral needs to be removed, inspected and cleaned where
necessary.
• A WL3 Firewall with a hot water option may require any calcium build up in the
hot tank to be removed, this depends on local water conditions
• No paperwork or cleaning records should be stored inside the WL3 Firewall.
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.
