Instructions On Changing The Co 2 Bottle - WaterLogic WL3 Firewall Technical Manual

8. 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 WL3 Firewall.
9. Check all the connections to ensure there are no water or CO
WL3 Firewall machine.
10. Check the electrical wall socket (polarity) and then make the electrical connection
to the WL3 by plugging the power lead into the socket on the rear of the WL3. Then
connect it to the electrical feed or wall power outlet. Turn on the power supply to
the WL3.
11. Re-fit the top and bottom covers and secure them using the screws removed
earlier, then turn on the red power switch. The WL3 will go through a self-test
cycle and the LED's will light automatically. When the self-test cycle completes, the
sparkling water model will automatically fill with water, whilst still water models will
need to be manually flushed by depressing the hot dispense button first or the cold
water dispense button. When the WL3 has completed filling flush through 10 litres
of water by depressing the hot, cold and sparkling buttons. Make sure the hot tank
is full of water and turn on the green heater and compressor switch at the rear of the
machine, the WL3 Firewall will then begin to cool and heat.
12. The water temperatures are pre-set at the factory to 5°c for the cold water and
87°c for the hot water.
13. 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.
14. The WL3 Firewall should be sanitized at installation.

Instructions
on Changing the CO
1. Turn off the empty CO cylinder and disconnect the CO
2
2. With the new bottle, remove the dust cap (if there is one in place), aiming the
valve away from you. Momentarily open the valve and purge some of the CO
to remove any dirt or dust that may have entered the nozzle.
3. Check that the rubber O-ring has not fallen out of the CO
when it has been removed from the empty CO
then attach the CO pressure regulator to the new bottle and connect via a length
2
of ¼" flexible hose to the WL3 Firewall.
4. Open the valve slowly simultaneously with step 5 below and observe the gauge
reading on the regulator, it should be at 3bar of pressure as this setting is pre-set,
but if not adjust were necessary.
5. Lift the yellow lever under top cover for 4-6 seconds to purge the gas line and
carbonator.(This must be done when you open the CO
tank is not damaged when initially pressured)
6. Place a container of at least 5 litres under the faucet and dispense sparkling
water until just the CO gas is being dispensed from the faucet. The WL3 will now

refill. This takes approximately 4 minutes. When the pump has stopped turn the CO
gas bottle off.
7. Record the regulator pressure, normally 3 Bar. After 5 minutes check the gauge
for any pressure drop as this indicates a leak and turn the CO
