New filters have a small amount of loose, harmless, carbon particles. Drain off
approximately 3 litres of water when first setting up or replacing filter.
Regular operation
The appliance starts automatically shortly after the electrical supply is turned on,
filling with water and heating.
The unit will display ‘Wait’ whilst it fills and heats. It will display ‘Ready' when water
can be drawn off.
To ensure that water is always hot, only small quantities are added constantly
during the heating cycle. The appliance is designed to be left on permanently, only
to be turned off for descaling or maintenance.

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.
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 the timely
replacement of the filter.
In common with all water boiler manufacturers, service calls resulting from
limescale are not covered by warranty.
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 DP10, 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°C.
Remove the water boiler top cover.
Remove the insulation from the top of the tank, then unscrew and remove
the tank lid.
Add the de-scaling agent slowly to avoid eruption of the water. Follow the
manufacturer’s instructions.
Replace the tank lid and outer lid cover. Attach an ‘Out of Use’ notice to the
boiler to prevent use during de-scaling.
Turn on the electricity and allow the boiler to run normally for 30 minutes.
Isolate the boiler and allow the water to cool.
Remove the boiler lid cover and tank lid and inspect the tank and level
sensor housings for scale deposits. If necessary, repeat the de-scaling
process.
In hard water areas manual descale may be required. Remove as much scale as
possible by hand paying particular attention to the level sensors and element.
Drain and flush all de-scaling agent from the tank completely as follows:
Drain all the water out of the tank–(Fig 2 G)
Failure to descale a unit may result in the boiler overfilling and leaking from the
overflow
