Maintenance And Servicing; Sanitising Or Descaling - WaterLogic WL100 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, Ambient.
• Every six months the filters must be changed.
• A WL100 with the 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 WL100.
1. Isolate the power to the WL100 by turning off the red switch and removing
the power cord at the rear of the WL100.
2. To access the filters, undo the screws at the front of the base cabinet panel,
and lift the two clips upwards and pull the panel towards you.
3. Remove both of the tubes from the elbow fittings at the top of the filter, then
remove the filter from the filter bracket.
4. Replace the filter cartridge with a new cartridge and flush externally to the
machine, once flushed refit the filter into the machine.
5. Inspect the electrical and water connections of the machine.
6. Check the air gap around the machine to ensure it is not blocked.
7. Insert the power lead into the back of the machine and turn on the red
switch.
8. Close the front of the machine and the top of the machine by fitting the
panels back to their original position.
9. 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.
10. Turn on the heater and compressor switch and allow the machine to cool
and heat the water.
11. 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 two more litres of water through the machine.

12. Wipe the outside surfaces (non abrasive cleaner), clean the drip tray, check
there is a 5cm air gap around the WL100.
13. Taste the water, ensure there are no carbon fines in the water, check the
WL100 functions to the customer's satisfaction. Should there be any taste
issues or carbon fines still in the water then flush the WL100 again.
SANITISING OR DE-SCALING
Please ensure that you do not accidentally drop sanitiser or de-scaler on any
of the WL100's water or electrical connections.
1. Connect an empty filter housing (Waterlogic) with an in and out pipe
fitting to the back of the machine water in-let, this will be needed to mix the
sanitizing solution and introduce it into the water circuit. Flush the solution
into the machine. Sanitising the machine using this method will allow the
whole cold water system from the point of entry to faucet (exit) to be sterilised/
sanitised.
2. Mix a solution of sanitizer in the empty filter housing.
3. Turn off the water supply to the WL100, 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.
5. Remove the top cover on the mini model and lower panel on the free
standing models.
6. Bypass the WL100 internal twist filters as no sanitiser should enter the
filters. These can be bypassed by using dummy (empty) filters (same applies
for de-scale).
7. Close the top cover, turn the power on and flush the cold water until the
sanitizer exits the faucet. Please ensure no sanitizer is allowed to enter the hot
tank. Let the WL100 stand for a minimum of 15 minutes and then flush out the
sanitizing solution. Replace or refit the filters, remove the empty filter housing
and reconnect the water supply to the WL100.
