INTRODUCTION
DESCRIPTION OF THE SPECIFICATIONS:
This floor standing electric boiler is available in 5 models :
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
- Model 57 with a power of 57,6 kW
- Model 115 with a power of 115,2 kW
- Model 144 with a power of 144 kW
- Model 201 with a power of 201,6 kW
- Model 259 with a power of 259,2 kW
The power circuit is supplied with 400 Volt tri phases without
neutral.
The control circuit is supplied with 230 Volt single phase.
CASING
The boiler is protected by a steel casing that has a red stove
enamelled finish.
HEATING BODY
The boiler heating body is constructed from mild steel with
welded joints. It is hydraulic tested at a pressure of 5,2 bar
(maximum working pressure = 4 bar).
HEATING ELEMENTS
Immersion heaters, constructed from stainless steel Incoloy 800
are mounted in the front of the boiler, provide the heating source
to the boiler.
CONNECTION
The boiler is suitable for connection to most heating and water
process systems, with a maximum working pressure of 4 bars and
a maximum temperature of 90°C. It can also be used in multiple
boiler installations allowing greater outputs to be achieved.
The boiler and connection glands are provided for the power
supply, the control supply and optional external controls.
CONTROL
The boiler is equipped with an electronic sequencing control that
constantly adapts the power required thanks to a four stage
modulation.
The boiler is commonly controlled by an external contact
(i.e. room thermostat). The maximum power can be limited to
25%, 50% or 75% by moving electrical bridges.
ELECTRICAL PROTECTION
The control circuit is protected by an internal 3 Amp MCB.
The power circuit is protected at its input by 3 power fuses.
Moreover, each contactor - supplying a pair of electric stars
(28,8kW) - is protected by an automatic thermal and magnetic
safety relay.

INSTRUCTIONS
USER DATA
All user controls are situated on the front panel of the boiler,
there are no user controls inside the boiler casing.
The following instructions assume that the boiler has been
commissioned, and that the system is filled with water and has
been fully vented.
SETTING UP
• Before switching on any electrical supplies to the boiler ensure
that the combined temperature and pressure gauge reads at
least 1 bar and the control thermostat is set to the desired
temperature.
• If any other auxiliary controls are fitted e.g. programmer, room
thermostats, cylinder thermostats etc, consult appropriate
manufacturers’ instructions to switch these on.
• Switch the winter/summer switch to winter position.
• Switch on any local means of isolation to boiler.
Ensure all the jacket panels are secured before
switching on electrical supply from the external
isolator.
• Switch the boiler on using the ON/OFF switch (a test of the
lights is done).
• After a short period of time the boiler temperature should
start to rise, indicated on combined temperature and pressure
gauge. The modulation level is displayed on the front panel
by the stage indicator lights. If the boiler fails to operate, the
overheat safety thermostat should be checked.
Access to the thermostat reset button is obtained by unscrewing
(anti-clockwise) the domed button cover on the front panel
(a screwdriver is not required).The reset button can then
be seen - press the button, a click should be heard and the
button is reset. If no click was heard the device is not at fault
and further investigation is required by a suitably qualified
engineer.
• The external programmer can now be set to allow on/off
periods as desired. The ON/OFF switch should be left in the
ON position during normal use.
• As with most boilers and heating appliances the casing and
pipework can get hot during normal running so the boiler must
not be covered and the surrounding area must be kept clear.
HEATING SYSTEM PRESSURE
The CH pressure must be a minimum of 1 bar and must be
checked by the end user on a regular basis. If the pressure drops
under 0.5 bar, the integrated water pressure switch blocks the
appliance until the pressure in the system returns to a level
above 0.8 bar.
The installer must fit an external filling loop to the system.
For more information, please ask your installer when the system
is delivered.
A pressure safety valve is provided with the appliance. If the
system pressure exceeds 4 bars, this valve opens and drains
the water from the system. In this case, please contact your
installer.

temperature.
• If the boiler is not in regular daily use during cold periods, it is
recommended that it is fitted with a frost sensing thermostat
to prevent the system from freezing.

INSTALLATION ROOM
The minimum clearance around the appliance must comply
with the figure shown opposite.
BOILER ROOM
• Electric boilers must be installed in boiler rooms complying
with the relevant technical standards and applicable
regulations.
• The appliance should never be installed outdoors, because
it has not been designed for and is not equipped with
automatic defrosting systems.
• If possible, install the boiler above the ground level, to
reduce the risk of flooding the electrical components.

FROST PROTECTION
The boiler is NOT fitted with frost protection. If the boiler is
being installed in a position where freezing could take place,
then a suitable external frost thermostat should be fitted.
CONNECTING TO THE SYSTEM
The boiler is designed to operate on a sealed system (ie. no
open vent or feed and expansion tank).
An adequate expansion vessel, sized accordingly must be
installed in the system.
