• 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 authorised 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.
It is recommended to check all electrical
connections of the sauna climate device at
least once a year. This can be done by a suit-
ably qualified person.
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;
SAUNA
ROOM
A prerequisite for the installation of the
sauna climate device is a properly prepared
sauna room. The thermal insulation of walls
and ceilings must be appropriate, other-
wise it will take too much time and energy
to heat the room. The power supply cables
for the heater and the fan must be indicat-
ed on the electrical connection board in
accordance with Table 1 (see pages 10–11).
SAUNA ROOM
VENTILATION
The air in the sauna room must be changed
at least six times an hour.
When using mechanical air extraction,
place the air supply above the sauna climate
device. When using natural air
extraction,
place the air supply under or next to the
sauna climate device. The air supply pipe
must have a diameter of 80 to 100 mm.
Install the air outlet near the floor, as far as
possible from the sauna climate device. The
diameter of the air extraction pipe must be
twice the diameter of the air supply pipe.
If the air outlet is in the washroom, there
must be a gap of at least 100 mm under the
sauna room door.
Exhaust ventilation in the sauna room is
mandatory.
The venting hole for drying (optional)
must be installed in the ceiling near the
wall oppo site to the sauna climate device
(closed during heating and sauna). The
sauna can also be dried by leaving the
door open after using the sauna. The sau-
na venti lation system should preferably
prevent the sauna exhaust air from enter-
ing other rooms, especially when using the
sauna climate device with salt balls.
