Introduction
Lincat automatic fill water boilers are designed for continuous operation and should only be
switched off for the purposes of maintenance or emergency.
Accessories
The new boiler is supplied with the following components and should be verified before
installation.
• Approved flexible water connection hose.
• Pack of de-scaling compound.
• Spillage tray and grid.
• Instruction booklet.
• Guarantee card.
The EB3 model is supplied with a 3 pin bonded plug and lead fitted with a 13Amp fuse as
standard.
The EB range of boilers is surface mounted and carries the option of being wall mounted. Wall
fixing kits are an optional extra.
The EB range has a unique drainage system to allow for ease of tank evacuation during routine
de-scaling of the appliance. It is not necessary to invert the appliance during the de-scaling
procedure.
These instructions must be retained for safekeeping and for future reference.
Please read carefully all the instructions before commencing with the
installation and commissioning of the appliance.

Warnings and Precautions
Please read the following carefully before commencing work on this equipment.
A competent installation engineer, in accordance with the installation instructions of this
appliance and all relevant local and national standards including the following must install this
appliance:
• Health and Safety at Works Acts
• IEE regulations
• BS Codes of Practice
• Local and National Building Regulations
• Fire Precautions Act 1971
• EN 60335-1:1994, EN 60335-2-21:1999, EN 60335-2-63:1993, EN 60529:1992 and BS 3456
part 102 section 102.21:1988
It is mandatory that all appliances are installed, commissioned and serviced by a qualified
and competent person as defined by the regulations in force in the country of installation.
During normal use of the appliance certain surface areas will become hot. These areas are
especially in the vicinity of the facet and spigot. Care should be taken to avoid potential injury
from burns and scolding whilst operating the appliance.
Scale formation within hot water appliances is problematic and more so in hard water areas.
Damage to the appliance caused by excessive scale build up may invalidate the warranty – see
notes on de-scaling.
Use only the supplied parts with the appliance. Introducing foreign components not approved by
the manufacturer may cause tainting of the water and may also invalidate the warranty.
Do not place foreign objects in the tank of the appliance.
Parts explosion, circuit and wiring diagrams are the sole property of Lincat and must not be
reproduced without the consent of the manufacturer.

Installation Preparation
Work Surfaces and Areas
• Ensure that the work surface upon which the appliance is to be sited is capable of sustaining
the working weight of the appliance.
• Consideration should be given for servicing requirements.
• Ensure that safe operational access to the appliance is unrestricted.
• Do not site the appliance directly beneath wall cupboards, other wall mounted appliances and
low ceilings that are susceptible to damage from water vapour.
• Where the appliance is to be wall mounted it is recommended that the safe working height
from the floor to the faucet is approximately 1400mm.
Water Connection
• Connection to the cold water supply and the appliance is made via the hose supplied. The
hose can be found inside the tank of the appliance and must be removed before installation
and commissioning.
• In hard water areas it is advisable to fit a filtration unit to limit scale deposits. A filter kit is
available as an optional extra.
Electrical Connection
• All electrical work must comply with all relevant wiring regulations and carried out by a
qualified electrician.
• EB3 models require a 13Amp-supply socket.
• EB4 models require a 20Amp supply.
• EB6 models require a 30Amp single or multi-phase supply.
• Isolation switches for the appliance must not be obstructed and be within easy reach.
Overflow and Drainage
• Due to the electronic function of the water boiler it is highly unlikely than an overflow would
occur. The boiler is primarily designed so that any overflow occurrence and condensation is
directly vented to the spillage tray.
• As an option the boiler overflow outlet may be connected to a drainage system.
Note: There may some steam emissions from the vent at the base of the appliance during the
initial fill stages but the steam emissions will lessen as the volume of water increases in the tank.
As an alternative the internal flexible hose may be redirected. See notes on Overflow and
Drainage in the Installation section.
WARNING. The flexible hose connected from the over flow also acts as a vent for the appliance.
Under no circumstances should this flexible hose become blocked or restricted in any way.

Installation
Qualified personnel must carry out all installation work.
Work Surface Installation
The work surface onto which the appliance is to be sited must have the relevant physical
properties to sustain the working weight of the relevant appliance.
Working Weights
EB3 30.5kg
EB4 34.5kg
EB6 46kg
EB6T 46kg
If water, electrical and drainage services are to be brought through the work surface ensure there
is sufficient cable slack, movement for the flexible inlet hose and drain tubing (optional) to allow
for free access maintenance and service personnel.
Where electrical sockets or electrical isolation points are fixed below the work surface then these
points must not be able to come into contact with water. Access to electrical isolating points must
not be obstructed in case of emergency. Instruction to the owner of the appliance must be given
on how to isolate the appliance in case of emergency.
The work surface must have a minimum depth of 600mm.
The spillage tray must be fitted with the appliance

Wall Bracket Installation
Where the appliance is to be mounted to a wall ensure the wall is constructed of a suitable
material to sustain the working weight of the boiler.
• To fit the wall bracket make a centre mark on the wall at approximately 1400mm from the
floor.
• In the orientation shown, align the hole in the centre rib of the wall bracket with the centre
mark on the wall.
• Ensuring the wall bracket is level, mark out the remaining holes.
• Drill 4 off 7mm diameter holes using a suitable masonry drill at a depth to
accommodate the wall-fixing plugs issued with the bracket.
• Fit the wall-fixing plugs and attach the wall bracket using the
screws issued with the wall bracket.
Fixing the Boiler to the Wall Bracket
• Align the upper wall bracket tabs with the slots in the top of the
back panel on the boiler.
• Align the lower wall bracket tabs with the slots in the base of the boiler.
• Clip the boiler into place.
• The boiler must be secured to the base of the bracket using M5 screws.
FLOOR LEVEL
Fitting the Spillage Tray Bracket
• Remove the four feet from the base of the boiler.
• Secure the spillage tray bracket to the base of the boiler using the four feet fixing positions.
The bracket is to be fitted with M5 screws issued with the bracket. Longer screws may
damage components within the boiler and therefore invalidate the warranty.
• Fit the spillage tray to the bracket.
Do not attach electrical cables or water supply pipes to the wall bracket.
Connection of the Water Supply
The minimum working pressure of the appliance is 20kPa (0.2Bar).
The maximum working pressure of the appliance is 1000kPa(10Bar).
• The appliance is to be plumbed to a suitable drinking water supply that complies with
national Water Bylaws.
• The recommended connection is made via the
flexible hose supplied with the appliance. The
fittings are ¾" BSP.
• The main water supply must have a double check
valve fitted.
• It is advisable to fit an isolation valve to the main
water supply and that where possible the flexible
hose is connected directly to it before connection
to the appliance is made. There must be
unrestricted access to the isolating valve.
• To minimise the scale build up in hard water areas
the optional filter kit may be connected between the
water isolating valve and the appliance.
