Värmebaronen EK 13
Flow
The electric cartridge requires a constant adequate flow to work. If
the heating system's valves are able to throttle circulation, an over-
flow valve must be installed.
The circulation pump must press the
water through the cartridge with the
flow direction shown in the figure.
Recommended flow: 0.3 litre/second,
∆
t = 10 °C.
Flow too low: • High difference between desired temperature
and achieved temperature.
• Irregular control with increased wear on the
electromechanical components, with reduced
service life as a result.
• Increased risk of the overheating protection
being triggered.
Flow too high: • Vibrations in the immersion heaters with noise
and reduced service life as a result.
• Unnecessary wear on the system's components.

Freestanding heating unit
EK 13 must be connected to:
Open system: The expansion tank is connected in an unbroken,
uninterruptible connection to the cartridge. The
distance between the top of the highest radiator
and the tank may not be less than 2.5 metres to
avoid oxygenation of the heating system.
Closed system:
The cartridge is connected to a closed expansion
tank and in an unbroken, uninterruptible
connection to a type-approved safety valve
with maximum 3 bar opening pressure and an
automatic vent valve.
Pipe installation
Installation must take place according to existing regulations
and standards.
The cartridge must be located indoors in a suitable location.
The cartridge must be installed horizontal with the pipe
connections vertical so that air that is released can escape.
The cartridge must be connected to an open or closed expan-
sion system.
A system with a closed expansion tank must undergo an
installation inspection prior to first operation. The inspection
must be carried out by a person who is qualified for the task.
The electric cartridge or expansion tank may not be replaced
without another inspection.
System principles
The system must be installed according to existing rules and
standards.
