Waterlogic 2 Firewall Technical Manual - Issue B, May 2014
Maintenance and Servicing
6 MONTH SERVICE PROCEDURE
This procedure should only be carried out by persons trained by Waterlogic
International or their approved distributors.
The following instructions cover models that can include Hot, Cold, Ambient.
• Every six months the filters and UV lamp must be changed.
• The Firewall quartz spiral must be removed, checked and cleaned every six
months if needed.
• A WL2 Firewall with a hot water option may require having any calcium build
up inside the hot tank removed, depending on local water conditions.
•
No paperwork or cleaning records should ever be stored inside
the WL2 Firewall.
1.
Isolate the power to the WL2 Firewall by turning off the red switch and removing
the power cord at the rear of the WL2 Firewall.
2.
To access the filters, undo the screws and release the clips located in front
of the lower front panel and remove the panel to gain access to the interior of
machine. To access the filters on a mini machine just remove the top cover. This is
a high voltage area and the machine should be isolated from the power supply.
3.
When a valved twist filter head is installed there is no need to turn off the water
supply; the water is automatically isolated when you remove the filter.
4.
To remove the Waterlogic filters, twist the filter anti-clockwise.
5.
The new filter will require flushing prior to being re-fitted in the WL2 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. The new filter can now be installed into the machine.
6.
Remove the UV lamp by unplugging the UV lamp connector and pulling the
lamp upwards.
7.
Check the quartz spiral for scale build up and clean if necessary.
8.
Fit the quartz spiral back into the Firewall Chamber taking great care at this
stage not to crack the quartz.
9.
Replace the UV lamp assembly and re-connect it. Do not touch the UV lamp
with bare hands.
10.
Inspect the electrical and water connections of the machine.
11.
Check the air gap around the machine to ensure it is not blocked.
12.
Turn on the red switch, on the back of the machine.
13.
Check that the UV lamp is alight by observing a blue glow from the top of the
UV cap. Do not remove the lamp from the holder whilst ignited and do not look
into an ignited UV light.
14.
Close the front of the machine and the top of the machine by fitting the panels
back to their original position.
15.
Flush through 5 litres of hot and 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.
16.
Turn on the heater and compressor switch and allow the machine to cool and
heat the water.
17.
Clean the outside of the machine with a non-abrasive anti-bacterial wipe or
cloth.
18.
Taste the water one final time and check the machine is cooling and heating
the water.
