• Read these instructions carefully before
installation and operation! Keep the
instructions in the boiler!
• Check that the boiler has not been
damaged during transport. Report
any transport damage to the carrier.
• Check that the delivery is complete.
• All installation must be performed
by an authorised person in accordance
with the existing regulations.
• Risk of electric shock. Never leave
the boiler door open!
• Never disable the safety equipment!
• The boiler must never be switched off
electrically unless the heating system
is full and the boiler vented.
• Correct installation in combination with
correct adjustment and continuous service
will produce high operational reliability
and good heating economy.
• The boiler must not be modified, changed
or converted in any way.
• Only authorised persons may work
on the boiler.
• Disconnect the boiler from the power
supply and lock the switches before
service/repairs.
• Never carry out maintenance work/
service on pressure-bearing parts
when they are pressurised.
• The boiler may not be used by children
or people with physical or mental
impairments. Nor by children/people
who lack knowledge of the boiler.
Children may not play with the boiler
or connected accessories.
• Always contact your installation engineer
for service.
• The type and manufacturing number of
the boiler must always be specified when
contacting Värmebaronen, see the boiler's
rating plate.
• Värmebaronen AB reserves the right to
change the specification, in accordance
with its policy of continuous improvement
and development, without prior notice.
• Subject to amendments and printing
and proofreading errors. Illustrations
may differ from the actual product.

Värmebaronen 400V3~: EP 450, -510, -540, -600, -700 TL / 690V3~: EP 600, -750 TL
Function
Electric boilers for heating systems or industrial pro-
cesses.
The boiler's power is divided into 30 power stages.
The boilers' control range is 20-95°C.
The output of the boilers can be restricted to one power
stage.
The electric boiler is CE marked as a unit and is clas-
sified as pressure equipment according to Directive
2014/68/EU, Article 4(3).
The electric boiler can be supplied with factory-fitted
safety equipment, reviewed by accredited body accord-
ing to EN 12828.
Final examination, under national laws, that the elec-
tric boiler has the necessary safety equipment shall be
carried out by an accredited body when assessing the
monitoring interval for the electric boiler.
The factory-fitted safety equipment contains safety
valve(s), high-pressure guard and automatic vent valves.
Double circulation pumps and ow guards are not re-
quired. The boiler can cope with zero ow from a safety
perspective.
A steam-collecting vessel is not required. The safety
valves are tted directly on the boiler's safety pipe.
Safety
The boilers have load-break switches which are acted
on via shunt release by the boiler's thermal relay and
pressure guards. The boilers do not restart automatically
after a power cut.
Operational reliability
The boilers are fitted with float switches and leakage current
measurement, which provides an early indication of any
faults in the immersion heaters, so that faults can rapidly
be dealt with, without unplanned stoppages.
Alarm indication
Alarms are indicated on the boiler's control panel.
Connection for external indication of a buzzer alarm,
alternating potential-free relay output.
Stainless steel immersion heaters
The immersion heaters are in stainless steel SS2353
with brass heads.
Pump maintenance operation
Connection for a circulation pump with a pump
maintenance operation function.
External stage and power control
Connection for external blocking, 0 - 5 V, 0 - 10 V and
4 -20 mA control of power.
External temperature setpoint
Connection for external setpoint in the form of 0 - 5 V,
0 - 10 V and 4 - 20 mA signal.
Output signal for present power and temperature
0 - 10 V signals for the number of power stages
connected and boiler temperature.
Load guard
Protects the main fuses; secondary transformers are
supplied with the boiler.
Reconnection after power cut
Power is reconnected after a power cut according
to recommendation.
Power supply to external unit
Fused 230 V~ output for supply to an external unit.
Aluminium and copper
To facilitate installation, the boilers are fitted with terminals
that make it possible to connect both aluminium and copper
cables. No splicing from aluminium is required.
Outdoor temperature compensator, option
Controls the boiler temperature in relation to the outdoor
temperature via an outdoor sensor.
Cooling fan
The boilers may be fitted with cooling fan(s) with air filters
for use in areas with high temperatures or dusty
atmospheres. Fan, included in EP 450, -510 BL and 700 TL.
Series connection for greater power, option
If more power is needed, two boilers can be controlled
in series
Temperature control in secondary circuit, option
When used with, for example, a heat exchanger, the
temperature in the secondary circuit can control the boiler.
