MECHANICAL INSTALLATION
The boiler must be installed on a vertical surface, with the base in a horizontal position, in a
location where it can be supervised by trained personnel. Ensure that the location it is fitted in is
frost-free.
WARNING
The unit must be installed on a solid concrete / brick wall by a qualified fitter. Lincat does not
accept any responsibility for the safety of any unit not installed this way.
Use the template provided, IS436, to mark the position of the 3 mounting holes. Drill the wall
and insert suitable wall plugs.
Remove the glass front / outer body of the boiler. Loosen the screw holding the lower centre
trim, slide the trim forward, re-tighten the screw. Remove the screw in the top of the boiler. Lock
open the drain tap. Carefully slide the the glass front and metal sides upwards and away from

ELECTRICAL INSTALLATION
For safety regulations the plug or means of disconnection must always be accessible.
This boiler must be earthed.
Check that the voltage of your electricity supply corresponds to the voltage shown on the serial
plate.
The boiler is supplied with a terminal block suitable for flexible wires upto 6mm
2
. Connection
wires may either be threaded through the cutout in the back panel or via a suitable 20mm
diameter glanded bush in the unit base (After removing the smaller of the two knock out panels,
marked B.)
Connection sequence is as detailed below
E Earth Green / Yellow Right terminal
N Neutral Blue Centre terminal
L Live Brown Left terminal
WATER INSTALLATION
Connection hoses may either be fed through the cutout in the back panel or via the larger of the
two knock out panels in the unit base, marked ‘A’. A blank rubber grommet is supplied and
should be cut to fit around the feed pipe and fitted into the unit base to seal it.
The inlet connection point on the inlet solenoid valve is ¾”BSP and should be connected to the
mains water supply via an accessible isolating tap.
Connect the condesate / overflow pipe to a suitable drain, considering any applicable local
water regulations. If required, the internal pipe may be disconnected from the external
connector and the pipe extended to pass through the cutout in the back panel and connected to
a suitable drain.
Turn on the water supply to check that there are no leaks.

Filter replacement
The “FILTER” display shows the estimated remaining life in the current filter cartridge. When the
filter needs replacing, a reminder message is displayed. This is followed by the change filter
screen.
The boiler can be used without a filter but scale may build up more quickly and water taste may
be affected.
Replace the filter as follows:

of the unit. It will contain a small amount of water.
2 Remove the black cap and place on the new filter.

filter.
CLEANING
Clean the external surfaces of the unit regularly to maintain hygiene.
Wipe the dispensing tap daily to remove any limescale deposits and check that the water outlet
is clear.
Wipe the unit down with a damp soft cloth.
Do not allow excess water to run into the unit.
Do not use abrasive creams or scourers.

MAINTENANCE
Filter: 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 the 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.
1 Wear protective clothing.
2 Isolate the boiler from the electricity supply.
3 Turn off the power and let the water cool to approximately 60ºC to avoid injury.
4 Remove the screw on the top of the boiler and slide off the body.
5 Remove the insulation on top of the tank, then unscrew and remove the tank lid.
6 Add the descaling agent a little at a time as some types can cause hot water to erupt.
Always follow the manufacturer’s instructions.
7 Replace the tank lid and outer body, and attach an “Out of Use” notice to the boiler to
prevent use during descaling.
8 Turn on the electricity and allow the boiler to heat and run normally for approximately 30
minutes.
9 Isolate the boiler and allow the water to cool.
10 Remove the outer body and tank lid and inspect the tank and level sensor housings for
scale deposits. If necessary repeat the descaling process.
11 Drain and flush all descaling agent from the tank completely as follows
i Unscrew the drain plug (Use a 24mm spanner to hold the plug and a 21mm socket on
a ratchet to remove it) from the bottom of the tank to drain all the water out.
