OPERATION
First use
1
Switch on the mains water supply and the electricity supply
2
Leave the boiler for 30 minutes to allow it to fill completely
3
Drain off approximately 5 litres of water to remove any loose carbon
particles from the filter.
Regular operation
The boiler starts automatically when the mains water supply is turned on. After
a short delay it fills with water and heats up. During the heating cycle small
quantities of water are added to ensure that hot water is always available at
the tap.
The water temperature, screen backlight and screen contrast can be adjusted
as required.
The boiler is designed to be left permanently switched on: it is only necessary
to turn it off for descaling or maintenance.

Slide tray out to remove and empty
Twist to the left and remove. See section on filter
replacement.
Descaling
The descaling procedure must be performed by trained personnel as it
requires the removal of panels from the boiler and access to live
electrical components.
The boiler should be descaled regularly to maintain efficient operation and
water quality. The frequency depends on the hardness of the local water and
timely replacement of the filter.
The boiler is best descaled at the end of the working day to allow the
descaling agent several hours to work. Lincat recommends its own descaling
agent, available from Lincat spares department, part code MS19.
