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 and
Sparkling water.
• 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 WL4 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 WL4 Firewall.
1. Isolate the power to the WL4 Firewall by turning off the green and red switches
at the rear of the WL4 Firewall and by removing the power cord.
2. To access the filters slide the locking lugs located adjacent to the water dispensing
faucet inward, then slide the top cover forward and lift it upward and back onto its
hinges. Hold the top cover open using the top cover support strut located on the
left hand side panel.
3. The two Waterlogic twist filters are at the front left hand side protruding through
the WL4 Firewall's upper metal shelf. Grip the 1st filter on the left and twist it clock
wise to release it. This action will also isolate the water supply. Please remember
that all Waterlogic twist filters are left handed thread. Pull the filter body upward
when it releases and take precautions not to allow the used filter to drip water inside
the WL4 Firewall or you can use the filter tool available from Waterlogic loosen and
tighten the filter.

WL4 Firewall through the drain valves located at the rear. Have an adequate size
container to drain the tanks into. (5L of water)
5. Remove the top cover of the Firewall chamber and remove the UV lamp first and
then release the water feed fittings to the quartz spiral. Remove the quartz spiral.
Clean the spiral removing any lime scale that may have adhered to the quartz surface.
It is important to clean the quartz to allow maximum UV purification to take place.
