Operation with vaporizer
(only for Bi-O / Vapor heaters)
Please clean the vaporizer in advance be-
fore the first use.
All parts and joints in contact with water should
be inspected regularly for defect in liquid tight-
ness during servicing and maintenance.
The control of the temperature and humidity of
the vaporizer is managed by the control unit.
The humidity level is controlled either propor-
tionally (time basis) or in the case a humidity
sensor is connected it is controlled basing on
the relative humidity value.
Please note that the relative humidity varies
greatly due to the varying temperature dis-
tribution in the cabin. The readings of the hy-
grometer and the readings at the control unit
can for that reason be very different.
Make sure that sufficient water is in the water
tank of the vaporizer before use.
Please fill the vaporizer tank up to a max of four
centimetres below the upper edge respectively
until the marking „MAX“ on the display panel.
Never add essences, oils or herbs directly
to the water tank; instead add these to the
herbal bowl on the holder of the vaporizer.
The volatile oils released from essences are car-
ried with the hot rising steam and will be dis-
tributed throughout the cabin.
In the case of the low water level in the water
tank during operation a buzzing signal indi-
cates the water shortage. To continue your
sauna session, you have to refill the tank after
a 5 minutes stop of the sauna control or after
switching to Finnish (dry) sauna for 5 minutes.
The heating element in the vaporizer must cool
down for 5 minutes before cold water is refilled.
Never pour water on the glowing heat-
ing elements. Besides of the danger of scald,
the heating element could be damaged.
Fill in the water up to the upper water level
marking.
Add herbs and essences to the herbal
bowl only.
Do not
pour essences into the va-
porizer tank!
By adding essences or any other addi-
tives for air humidity, a health hazard cannot
be removed. It is advised not to use those
additives apart from the recommended ones
by the manufacturer of the oven.
If additives are put in the water, this generally
leads to a foaming of the water. In this case the
water must be drained and the interior of the
cold reservoir washed out with a cloth soaked
in alcohol or mineral spirits. Even small remain-
ders of essences in the vaporizer will change
the natural molecular structure of the water.
Attention: Risk of scalding at the steam
outlet. Essences and herbs are to be placed
in the herb dish only.
Caution by control units with af-
ter-heating mode! Never leave herbal bags
in the herbal bowl during the after-heat-
ing mode after a humid (steam) operation.
These may dry out rapidly in this case and a
present a fire hazard! For fire safety reasons
only herbs in perforated aluminium bags
may be used.
