Maintenance and care
All sauna heaters are made of a corrosion-
resistant material. You should maintain and
care for the device so that you can enjoy
your sauna heater for a long time. you must
make sure that all openings and radiation
plates in the vacuum area are kept free of
obstructions. By drawing in fresh air, these
can easily become blocked with
fl uff and
dust. This restricts the air convection of the
sauna heater and unauthorized tempera-
tures can occur.
Clean or remove limescale from the device
as required. Please contact your sauna
dealer or the manufacturing factory if you
notice any defects or signs of wear and tear.
If you haven't used your sauna for a
while, make sure that no hand towels,
detergents or other objects have been
placed on the sauna heater or evaporator
before starting the sauna.
DIN VDE part 703 must be observed for
installation of the sauna heaters!
This norm, in the latest version valid since
February 2006 with amendments to paragraph
703.412.05, makes the following statement;
quote:
The additional protection must be provided for all
of the sauna's electrical circuits through one or
more residual current devices (RCD) with a dif-
ferential measurement current no higher than 30
mA, with the exception of sauna heaters.
EN 60335-1 DIN VDE part 1 from January
2001 states the following under paragraph 13;
quote:
The leakage current may not exceed the fol-
lowing values at operating temperature:
- For fi xed heaters under protection class I: 0.75
mA or 0.75 mA per kW measurement detection of
the device, depending on which value is higher,
with a maximum value of 5 mA.
If a residual current device (RCD) is installed,
make sure that no other electrical consumers
are protected using this RCD.
According to the current status of technology,
it does not make sense to use vapor-tight heat-
ers in saunas. In some cases, the magnesium-
oxide fi lling in the heaters by draw moisture
from the air through the vapor-diffusion sili-
cone seal which may lead to the RCD trigger-
ing in a few cases. This is a physical process
and is not a manufacturing error.
In this case, the heater must be heated by a
specialist under supervision, whereby the
function of the RCD is by-passed. After the
moisture has been drawn from the heating
rods after approx. 10 mins, the RCD can be in-
corporated in the electrical circuit again!
If the sauna is not used very often, we rec-
ommend heating it approximately every six
weeks so that moisture does not accumulate
in the heating rods.
If the RCD is triggered during initialization, the
electrical installation must be checked once
again.
The electrical fi tter is responsible for correct
connection of the heaters and liability by the
manufacturer is therefore excluded!
Suitable protective gloves must be
worn when cleaning the outer coating parts
of blades.
