Attention! Do not overtighten nut
– Glass Might Break.
Please consider all important installation
instructions of this instruction manual.
Additionally, this heating device has an
evaporator element. Please note that it
is necessary to use a control unit for the
operation with wet hot air. Please choose
the degree of humidity according to the
information of the instruction manual of
the control unit.

The upper clamp (Fig 5) is used as upper
water gauge (with manual filling), the lower
clamp marks the minimal water level (except
for fixed water connection).

In the case that 2 vaporisers are being
operated at the same time, it is necessary
to note that both vaporisers are laterally shif-
ted, in order to guarantee that no vaporiser
bag runs dry.
Thus, the installation will be carried out on
the left side with a T-piece 1/2“, in this case
the square plug shows forwards whereas
the hose clip shows to the middle of the
oven. See Fig 6

Please cut the length of the silicone-hose
that in connection between the two connec-
tion-pieces, left and right, the centre of the
hose does not drop down.
Put silicone hose onto both spouts of the
T-pieces and safeguard it with hose-band.

Operation with Vaporiser
Fill water up to the upper marking line with
appropriate jar via funnel tube. (15 - 18 kW
= 5 l, 21 - 30 kW = 10 l)
Fill in water until the water level at the glass
tube reaches the upper bracket (Fig 9). Do
not overfill.
Fig. 9
Attention: At damp outlet risk of
scalding. Put herbs and essences
only into herb bowl.
The vaporiser will be regulated via the
control unit. You get a humidity value that
will either be regulated via a nominal/actual
value comparison at the sensor, or which will
be determined via a clock pulse.
Please note that the relative humidity values
will significantly vary due to different tempe-
rature distributions in the cabin. Thus, the in-
dication at the hygrometer and the indication
at the control unit may significantly differ.
Please check if the water tank is empty
prior to having a sauna. Remaining water
must be emptied out. Now, fill water into the
filling funnel up to the upper water gauge
(Fig 10).

Herb bowl
Filling funnel
This amount is sufficient for sauna baths of
two or three hours.
Please regulate the humidity degree at
the control unit. Never add essences,
essential oils or herbs to the water, but
put them into the herb bowl on the cover
of the vaporiser
The hot, ascending vapour releases essen-
tial oils which will be distributed in the cabin
automatically.
In case the store of water has been used
up, a ring tone sounds and indicates water
scarcity. However, if you want to continue

your sauna bath, you can add water into the
storage tank after the control unit had been
put to „Stop“ 5 minutes before or has been
operated for 5 minutes in the mode „Finnish
Sauna“. The heating rod in the vaporiser
must cool down for 5 minutes before cold
water can be filled in.
Never fill water onto the red hot
heating rod. Besides the risk of
scalding, the heating rod could be da-
maged.
If any additives have once been added to
the water, normally this can result in over-
boiling foamily water. In this case, the water
must be discharged and the cold container
must be washed out with a cloth that has
been drenched in alcohol or spirit. Even the
smallest residues of essences on the wall of
the vaporiser change the natural structure
of the water.
Take care with control units that have follow
up heating times.
After the wet bath, never leave
the herb bags in the herb
bowl during the follow up heating times.
They would immediately dry out and
could cause fire hazard!
Connection to Fixed Water Net
We recommend the usage of a fixed water
connection, in order to prevent the vaporiser
from running dry.
Decalcifying the Vaporiser
Please ask your local supply company
for the hardness of your water. Within the
hardness degree I (1-7 German Degrees
of Hardness) the device works normally
trouble-free and must only be decalcified
on demand.
If your water is within the degrees of hard-
ness II - IV, it is necessary to have the vapori-
ser decalcified from time to time (depending
on the degree of hardness).
For this, add decalcifying agents for dome-
stic appliances to the water in the vaporiser
according to manufacturer information. Bring
the mixture of water and decalcifying agents
to a boil for ten minutes and have it cooled
down subsequently.
After it has been cooled down discharge the
mixture from the vaporiser and rinse out with
cold water at least twice. Please consider
the instructions of the manufacturer of the
calcifying agents.
Attention!
The device must be separated
from the power supply system in the case
of any cleaning or maintenance jobs, in
case accessory or plates are changed,
or in the case of any repair works in
operation mode.
