CLEANING
Do not use a water jet or steam cleaner, and do not immerse this appliance.
Clean all panels with warm water and mild detergent, do not use abrasive
materials. Dry with a soft cloth.
Slide out and empty the drip tray regularly, and wipe the dispensing nozzle daily to
remove limescale deposits.
De-scaling
The boiler should be de-scaled regularly to maintain efficient operation and water
quality. The frequency depends on the hardness of the water and timely
replacement of the filter.
The de-scaling procedure must be performed by trained personnel as it
requires the removal of panels from the boiler giving access to live electrical
components.
De-scaling the boiler at the end of the working day gives the de-scaling agent
several hours to work. Lincat recommend our own de-scaling agent MS19,
available from our Spares department.
Wear protective clothing.
Isolate the boiler from the electrical supply.
Turn off the power and allow the water to cool to 60 Deg C.
Using a 3mm allen key, remove the screw in the top of the boiler.
Remove the insulation from the top of the tank. Unscrew and remove the tank lid.
Add the de-scaling agent slowly to avoid eruption of the water, following the
manufacturers instructions.
Replace tank lid and outer lid and attach an „Out of Use‟ notice to prevent use
during de-scaling.
Turn on the electricity and run the boiler normally for 30 minutes. Isolate the boiler
and allow the water to cool.
Remove both outer and tank lids again. Inspect the tank and level sensor housings
for scale deposits. If necessary, repeat the de-scaling process.
Drain and flush de-scaling agent as follows:
