Maintenance - Saunum Professional Bedienungs- Und Installationsanleitung

• Check the stones. Stones that are
placed too tightly, stones falling
down/sinking closer over time, or
the wrong type of stone may inter-
fere with the air flow through the
heater and cause the surrounding
materials to overheat.
• Make sure that no heating ele-
ments are visible between the
stones. If the heating elements
are visible, lift the cooled stones
so that the heating elements are
completely covered.
NB! Too sparsely placed stones allow the
heating elements to overheat and worsen
the indoor climate of the sauna room. It
may cause a fire hazard!
THE WOODEN SURFACES OF THE SAUNA
ROOM BECOME DIRTY OVER TIME.
This process may be accelerated by:
• sunlight;
• heat from the heater;
• wall protectors (protection equip-
ment has poor heat resistance);
• fine particles from the stones.
THE HEATER SMELLS.
• See section HEATING THE SAUNA
ROOM page 13.
• A hot heater may amplify odours
mixed with air, but this, however,
is not caused by the sauna nor the
heater. Causes include paint, glue,
oil, spices, etc.

THE SAUNA CLIMATE DEVICE IS MAKING
NOISE.
• There is always a certain noise
when the fan is running. If it is not
uniform and/or accompanied by a
metallic sound, the fan is likely to
need maintenance or repair. Check
that there are no foreign objects in
the fan air vents.
• Try switching the fan to a lower
speed.
• Loud sounds are likely to be caused
by stones cracking due to heat.
• Thermal expansion of the heater
parts may cause noise when the
heater warms up.

MAINTENANCE

Due to large temperature fluctuations,
stones tend to break down. Stones must
be restacked at least once a year and even
more frequently when using the sauna
often. When restacking the stones, remove
stone fragments from the bottom of the
heater and replace the broken stones with
new ones. By monitoring this, the heating
capacity of the heater remains optimal and
the risk of overheating is avoided.
If you use Himalayan salt balls with the
sauna climate device, it is recommended
to inspect the salt balls once a year and, if
necessary, replace worn and broken balls
with new ones. Make sure that there are no
foreign objects in the fan air vents of the
sauna climate device.
CAUTION! Before maintaining and clean-
ing the sauna climate device, the device
power supply must be disconnected from
the mains, and the moving parts of the unit
must completely stop.
Before servicing and cleaning the sauna
climate device, make sure that:
• the sauna climate device is discon-
nected from the mains (in addition
to the device's power switch, also by
means of over-current fuses);
• the device fan has stopped com-
pletely;
• the prescribed occupational safety
and personal protective equipment
is used when performing the work;
• the connection cables are undam-
aged. In the event of damage to the
connection cables, have the cables
replaced by a qualified electrician
in accordance with the applicable
standards and requirements before
continuing maintenance and clean-
ing work.
The device housing can be cleaned with
a cloth dampened with water. Do not use
pressure washers, running water, chemical
cleaners, or solvents to clean the housing!
Use a 10% citric acid solution to remove
scale and rinse with water.
Excessive dirt can prevent the fan rotor
from operating correctly, causing an in-
crease in noise when operating the sauna
climate device. Noise may also increase due
to damage/bending of the fan blades. Make
sure that there are no foreign objects or salt
balls in the working area of the fan rotor.
Generally, the fan does not need to be
cleaned more than once a year. The fan
may only be cleaned by a person autho­
rised by Saunum.
Using compressed air to clean the fan can
permanently damage the fan rotor! The fan
bearings are maintenance-free and must
be replaced if problems occur.
