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.

COMMISSIONING
COMMISSIONING - WATER
1. The system must be thoroughly flushed prior to connection
ENGLISHFRANCAISNEDERLANDSESPAÑOLITALIANODEUTSCH
of the boiler. The system water should be treated to prevent
general corrosion and deposition of scale or sludge in the
boiler. If installing the boiler onto an existing system, ACV
recommend that an approved system cleaner is used.
2. Fill and pressurise the boiler and system to 1.5 bar, making
sure to vent the boiler via the automatic air vent on top of the
boiler. Note that the black dust cap on the air vent should be
left loose to allow the auto vent to function.
3. Check for leaks.
COMMISSIONING - ELECTRICAL
The Electrical installation supplying this boiler must conform to
the current IEE Regulations.
1. Remove the front and the right-handside. Check all electrical
connections for tightness.
2. Ensure all internal relays, contactors etc are secure on the
DIN rails.
3. Set panel control main switches to off.
4. Set internal MCB to off position.
5. Set the control thermostat to desired temperature.
STARTING THE BOILER
1. Switch on internal MCB
2. Fit and secure all panels
3. Switch on local isolator to boiler
4. Turn the boiler on using the ON/OFF switch
5. The first stage energises as indicated by the panel light.
The temperature will now rise as indicated by the combined
temperature and pressure gauge. As long as the control
thermostat set-point is not reached, the next stage is
energised every 2 minutes until all the stages are energised.
When the control thermostat set-point is reached, the last
stage is de-ernergized every 30 seconds until all the stages
are de-energized.
Once these procedures have been followed the system can be
left to operate normally.
After one week of operation all electrical connections
should be re-checked. The fixing nuts must of the
heating elements must be re-tightened at the nominal
torque of 10 Nm following the tightening sequence
mentioned in maintenance section.

MAINTENANCE
MAINTENANCE
For safety reasons it is recommended that the boiler is serviced
annually and that servicing is carried out by a qualified service
engineer.
Before carrying out any work on the system
ensure that the boiler is cool and all
electrical supplies are isolated.
1. After removing the front and the right panels, Undertake
a visual inspection of the boiler checking for signs of water
leakage from gaskets, and the components on top of the
boiler.
2. Undertake a visual inspection of all wiring in the boiler casing
checking for signs of overheating or burning.
3. Check all push-on electrical connectors for tightness and
good connection to the relative components.
4. Using a correct fitting screwdriver check all electrical
terminals on DIN rails and on all components for tightness.
5. Re-tight the fixing nuts of the heating element at nominal
torque of 10 Nm following the tightening sequence.
6. Check all individual circuit breakers are in the normal
position. If some fuses have tripped, check the wiring and the
resistance before reactivating them.
7. Replacement of the heating element (if required).
7. Replacement of the main fuses (if required)
