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 lime scale 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 lime
scale 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 outer surround secured by 3 screws.

Remove the top cover secured by 5 screws.

Remove the insulation from the top of the tank, then unscrew and remove
the tank lid secured by 8 screws.


manufacturer’s instructions.

Replace the tank lid, top cover and outer surround. Att
ach 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 outer surround, top 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 E)
Failure to descale a unit may result in the boiler overfilling and leaking from the
overflow.
