Maintenance And Servicing; Sanitising Or Descaling - WaterLogic WL2000IT Technical Manual

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 and Ambient.
• Every six months the filters and UV lamp must be changed.
• The quartz sleeve must be removed, checked and cleaned every six months if
needed.
• A WL 2000IT 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 WL 2000IT.
1. Isolate the power to the WL 2000IT by turning off the red switch and removing
the power cord at the rear of the WL 2000IT.
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 anti-clockwise and replace with a new
Waterlogic twist filter, twist clockwise.
5.Remove the Waterlogic UV lamp by unplugging the UV loom connector and
pulling the lamp upwards.
6. Check the quartz sleeve for scale build up and clean if necessary.
7. Fit the Quartz sleeve back into the unit taking great care at this stage not to
crack the Quartz.
8. Replace the UV lamp assembly and re-connect it. Do not touch the UV lamp
with bare hands.
9. Inspect the electrical and water connections of the machine.
10. Check the air gap around the machine to ensure it is not blocked.
11. Turn on red switch, on the back of the machine.

12. 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 holder whilst ignited and do not look into an
ignited UV light.
13. Close the front of the machine and the top of the machine by fitting the panels
back to their original position.
14. Flush 10 litres of hot water and 5 litres of cold water through the machine to
ensure that the filters are generated and the water is running clear of any carbon
fines.
15. Turn on the heater and compressor switch and allow the machine to cool and
heat the water.
16 Taste the water and check the machine is clean and functions to the customer's
satisfaction. If you are not satisfied with the quality of the water, flush 2 more litres
of water through the machine
17. Wipe the outside surfaces (non-abrasive cleaner), clean the drip tray, check
there is a 50mm air gap around the WL 2000IT.
18. Taste the water, ensure there are no carbon fines in the water, and check the
WL 2000IT functions to the customer's satisfaction. Should there be any taste
issues or carbon fines still in the water then flush the WL 2000IT again.
SANITISING OR DE-SCALING
Please ensure that you do not accidentally drop sanitiser or de-scaler on any of
the WL 2000IT's water or electrical connections.
1. An empty filter housing, as used on the AMETEK filter system fitted with in and
out pipe fittings, will be needed to mix the sanitizing solution. Flush the solution
into the machine from the rear bulkhead. Sanitising the machine using this method
will allow the whole cold water system from entry to exit to be sterilised, including
the carbonation pump.
2. Mix a solution of sanitiser in the empty filter housing.
3. Turn off the water supply to the WL 2000IT, release the internal water pressure
by momentarily pushing the cold water button. Disconnect the water feed pipe
from the rear water in bulkhead of the machine.
4. Fit the water feed pipe to the inlet side of the filter housing with the sanitiser in.
Connect a length of 1/4" inch water pipe from the outlet of the filter housing to the
water 'IN' bulkhead at the rear of the machine.
