Waterlogic 2 Firewall Technical Manual - Issue B, May 2014
9.
If installing a hot and cold model, do the following, otherwise go to point 10.
Select the hot water option and press the dispense button to start flushing water
through the machine filter and hot tank. The filter will produce carbon fines at first
and the water may have a black appearance. Continue to flush 10 litres of water.
10.
Select the cold water option and press the dispense button and flush for 10 litres
of water through the cold tank. This will flush the filter and clean any residual water
from the machine.
11.
Check the machine for any water leaks and ensure that all water fittings are se-
cured properly.
12.
Once you are satisfied that water is passing through both the hot and cold tank
successfully then turn on the heater/compressor switch at the back of the machine.
The machine will now start to heat and chill.
13.
The hot water will heat to approximately 87°C.
14.
The cold tank will start cooling. When the machine has reached the target tem-
perature the compressor will stop running. The temperature will continue to drop as
any ice that has formed on the sides of the tanks will start to melt and equalize the
tank temperature.
15.
To test the water temperature, then please ensure that you use an accurate pre-
viously calibrated thermometer.
16.
Please ensure that the cold water produced has a good taste. If you detect a
plastic taste then it is an indication that the machine needs to be flushed again.
17.
Check the machine to make sure it is electrically safe.
18.
The WL2 Firewall should be sanitised at installation.
19.
The WL2 Firewall must not be installed in direct sunlight, adjacent to a heat
source, or in an ambient room temperature above 30°C or below 5°C.
INSTALLATION KIT
The WL2 Firewall must be installed according to the local guidelines and a pressure
reducer must be installed as part of the installation. The pressure reducer should
not be set higher than 3bar.
• The WL2 Firewall should not be connected to water supplies of unknown bacterial
quality or those not already fit for human consumption. The WL2 Firewall should
only be connected to a Potable drinking water supply.
• The filter on the WL2 Firewall must be changed every 6 months.
• The UV lamp on the WL2 Firewall must be changed every 6 months.
• The cold tank should also be flushed and sanitised every 6 months.
