2.5. Changing The Location of The Control Panel (For Models DI-6D, DI-6K, DI-8K, DI-10K)
The heater control panel's location may only be switched by a professional with sufficient training. The control
panel has been factory installed to be used from the front of the heater. It may be turned to point to the side of the
heater in the following manner: 1) Release the attachment screw underneath the control panel. 2) Move the
rubber gaskets on the decorative piping further away from the control panel. 3) Remove the control panel by
pulling it outwards from the piping (the plastic material used tolerates bending well). 4) The keyboard connector
cable in the connection room has some slack to allow pulling the control panel further from the piping. 5) Detach
the cable at the keyboard's row connector. 6) Move the cable to the required side and pull it through. 7) Assemble
in reverse order.
2.6. Connecting A Separate CC Control Panel (For Models DI-6T, DI-8T, DI-10T)
There are no limits to the distance of the control panel from the sauna. The control cable from the CC control
panel is a 6 line low voltage cable that is connected to the circuit board on the heater according to the connection
diagram. The row connection numbering of the circuit board and the CC control panel are identical. Attach the
cable from the sensor to connectors 17 and 18 of the CC control panel.
3 SAUNA ROOM INSTRUCTIONS
3.1. The Sauna Room
The heat insulation of walls and ceiling must be sufficient, to avoid losing too much heat to the outside. Wood is
the most suitable surface material A wooden surface warms up quickly and radiates a pleasantly even heat to the
bather's skin. You should avoid masonry and other stone surfaces in the walls, as stone takes in too much heat
and would require a significantly more powerful heater than a wooden room of the same size. One square meter
of stone surface on the wall or ceiling above the heater's level is equal to 2-3 cubic meters of additional volume in
the room. A glass door and windows have similar effects on the sizing. Log walls require an additional 25% of
added power to the volume calculated in this manner.
Excessive height also adds unnecessary volume to the room. The distance between the highest bench and the
ceiling should not be too high, as the temperature decreases towards the floor.
A sufficient distance from bench to ceiling is about 110-120 cm. We recommend locating the heater as low as
possible (within safety limits). The sizes of sauna rooms are given in table 2.
3.2. Correct Air Circulation
Sufficient air exchange in the sauna is very important. A suitable amount for a family sauna would be about 6
times the sauna's volume per hour. Air removal happens either through gravity (= traditional, “natural
circulation”) or mechanically, through an air removal fan.
Mechanical air circulation (pictures 4 and 5):
Fresh air is taken in (preferably from outside the house) through a 100 mm diameter pipe that is at least 500 mm
above the heater (a). The fresh air may also be piped in below the heater, close to the floor (b), as long as you
make sure that the cool air flow does not go straight along the floor to the exit air vent. The most important aspect
in air circulation is to ensure an efficient mixing of fresh air with heated air and the vapor from the thrown water.
The exit air vent should be preferably placed below the benches (c), as far from the air intake as possible.
The exit air may also be fed through the washing room, e.g. underneath the door (e). The sauna should also have
a drying valve (f) behind the benches, near the ceiling. The drying valve is closed during the heating and bathing
phases and opened for the final drying out. The circulation fan is kept running throughout the bathing and
afterwards. It may be stopped for the preheating phase.
Gravity circulation – i.e. natural circulation (picture 6):
Fresh air is taken in (preferably from outside the house) through a 100 mm diameter pipe, preferably from
underneath the heater or its immediate vicinity close to the floor (b) or, alternatively, above the heater (a). The
most important aspect in air circulation is to ensure an efficient mixing of fresh air with heated air and the vapor
from the thrown water. The exit air is fed out preferably from underneath the benches (d). Drying valve near the
ceiling (f). The exit air vent should be placed as far from the fresh air intake as possible. The exit air may also be
fed through the washing room, e.g. underneath the door (e). The exit air vent may be closed during preheating.
The exit air vent must be larger that the intake and be located higher up.
