Maintenance And Servicing - WaterLogic WL Cube Firewall Technical Manual

Maintenance and Servicing

• The Cube must be serviced every 12 months, but we strongly recommend
the UV lamp and filters be changed every six months.
• The Cube may require any calcium build up in the hot tank to be removed,
this depends on the local water conditions.
• No paperwork or cleaning records should be stored inside the Cube.
• To reset the filter timer, hold down the hot and cold icons simultaneously
for 10 seconds.
The items required to complete this procedure are:
• Rubber Gloves
• Phillips Screwdriver
• Replacement filter cartridge(s)
• A container that can hold 5 litres
• New 13 watt UV lamp
• Non-abrasive anti-bacterial wipe or cloth
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 selecting the cold water
option until the water stops being dispensed.
3. Isolate the power to the Cube 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.
4. Remove the top cover from the Cube by undoing the two screws located at the
back of the machine, then slide the panel backwards and lift up.
5. Take out the filter by un-clicking the loop at the top of the filter housing and
pulling it in an upward motion. If there are two filters in the machine then both of
these need to be removed.
6. Unscrew the filter housing to expose the used filter cartridge. This cartridge can
then be removed from the filter housing and replaced by a new one. Return the
filter(s) into the correct position in the machine; ensuring that it is pushed firmly into
place as the valves will be reopened by the insertion of the filter.
7. Remove the UV lamp by unplugging the UV loom, and pulling the lamp upwards.
8. Examine the UV loom for any discolouration or wear, if there is any visible remove
the loom and replace with a new one.
9. Reconnect and replace the UV lamp assembly, making sure not to touch the new
UV lamp with bare hands as this will shorten the life of the lamp.
10.Inspect all of the electrical and water connections on the machine, and take any
action necessary to prevent a fault from occurring.

11. Check the faucet nipple for any calcium build up or any visible damage and clean
or replace it if necessary.
12.Reassemble the machine and secure all panels with screws.
13.Check that the air gap around the machine is sufficient and there is nothing
blocking the ventilation.
14.Reconnect the power to the machine and turn the red switch at the rear of the
machine to the 'on' position. Turn on the water supply.
15.The filter(s) now need to be flushed. Do this by selecting the ambient water option
and dispensing 10 liters of water through the machine. This will sufficiently generate
the filter and remove any excess black carbon fines.
16.The green heater and compressor switch can now be turned on.
17. Select the hot icon, then select and hold the main dispense button immediately
after selecting the hot icon.
18. Dispense at least 200ml of hot water.
19. The machine will now begin to heat / chill the water.
20. Clean the outside of the machine with a non-abrasive anti-bacterial wipe or
cloth.
21. Taste the water one final time and check it is cooling and heating the water.

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. 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 selecting the cold water
