and during the operation.
I/O
Main switch Operation elements
2. Bathing types
2.1. Sauna
Sauna
With temperatures of 85 - 100 °C and a low relative humidity.
WARM AIR BATH
With extra mild climate, with temperatures of 45 - 60 °C and a relative humidity of up to approx.
20 %.
2.2. Softclima
Soft steam bath
As gentle and humid bath with temperatures of 50 - 60 °C and infinitely adjustable humidity.
With the Soft Steam Bath, the temperature and the relative humidity are controlled by a
microprocessor controller.
Herbal Bath
With same climate values as for soft steam bath, and additional evaporation of herbal extracts
and scent extracts mixed with water. This improves the effect of the soft steam bath.
Taking a sauna in your Klafs sauna cabin should benefit your health and well-being.
Therefore: Don't overdo it ! That applies to the temperature, the relative humidity and the bathing time.
Orientate yourself not only on the given bathing times, but also on your condition. Leave the cabin as
soon as you no longer feel well.
3. Technical data
Control System Type 18043: 3/N/PE ~400 V, max. 9 kW.
Operating conditions: Temperature 0 °C to 35 °C, max. 80 % relative humidity.

10. Maintenance and Cleaning
10.1. Cleaning the sauna cabin
The high humidity level in Softclima mode does not harm the wood of your cubicle.
The requirement is that the cabin is well aired out after usage.
Never hose down inner cabin walls, bench or seats with water or a high pressure
cleaner!
Dirty benches
Wipe the wooden surfaces with a damp cloth.
If necessary, sand the surface of the benches with fine sandpaper.
The benches can also be washed off with a 3 %- hydrogen peroxide solution (available in
specialized stores).
Disinfectants are highly corrosive!
Therefore, pay attention to the relevant safety regulations!
Use household rubber gloves!
The outer cabin walls are impregnated or glazed.
In no case glaze, paint or impregnate the inner panelling or the cabin inner walls and
units (benches etc.).
