2Safety
2.1 Intended use
The automatic sauna splash system type PLUS 8 Basic may only be used for the purposes indicated in
Chapter 3.2, Product description! Also pay attention to the locally applicable regulations concerning acci-
dent prevention, occupational safety and drinking water protection!
2.2 Safety notices
Carefully read and pay attention to the operating instructions prior to installation and use of the device!
Work on the device and changes in the settings may only be carried out by properly trained and instructed
persons! It is of particular importance to comply with the rules for occupational safety and accident pre-
vention and to wear protective clothing.
Pay attention to the warning notices on the device
2.2.1 Handling of chemicals, risks to humans and the environment
Important information concerning the handling of chemicals and fragrances can be
found in the safety data sheets provided by the fragrance manufacturers!
With the automatic sauna splash system, a fragrance is added to the water and dosed on the sauna heater.
The fragrance concentration in the water is so low that there is no danger for people.
DANGER! IRRITATION!
The undiluted fragrances may cause irritation and allergic reactions.
HIGHLY FLAMMABLE!
The undiluted fragrances may be highly flammable. This may cause injuries and pose
a danger to personnel and the environment. For this reason, the greatest possible care
must be taken during all work!
CAUTION!
In high concentrations, the fragrances may be harmful to health!
In the event of an emergency when handling chemicals, you can contact the
Emergency Poison Centre!
Emergency number:
Munich Emergency Poison Centre (or any other Poison Centre)
Phone: [phone]
Each time the fragrance is refilled,
check the pump's dosing hose and
renew it, if necessary.

2.2.2 Protective measures and rules of conduct
CAUTION!
The automatic sauna splash system is supplied with water from the drinking water
network.
The safety combination integrated in the device is a safety device in accordance with
DIN EN 1717 (Germany and EU) for non-toxic liquids with free outlet, for the protec-
tion of the water network. For this purpose, the splash line from the device to the
oven shower head must be laid in such a way that the line can drain itself (at a decline,
without water trap, without non-return valve).
If the splash line cannot drain (e.g., installed at an incline, or water trap in the line), a
system separation unit in accordance with DIN EN 1717 for non-toxic liquids without
free outlet must be installed in the inlet of the automatic sauna splash system. In ad-
dition, a sauna splash connection set must be used. The connection set is available in
the following lengths: 5 m, 10 m, 15 m, 20 m
Pay attention to the locally applicable regulations!
ATTENTION!
It is not permitted to make any modifications to the device. If this specification is not
observed, the warranty obligation and product liability will expire!

3.2 Product description
The automatic sauna splash system Sauna Plus 8 Basic is a dosing system for a fully automated splash on
the sauna heater. During the splash, a fragrance is automatically dosed into the splash water.
The pause time, the quantity of water (= splash quantity) and the fragrance quantity (= scent intensity)
can be set individually via the control unit.
The device can be operated via an internal cyclic programme or via an optional push button. The splash
system can also be activated externally via the “button input”.
Function
For a splash, the solenoid valve (4) opens and the splash water flows to the sauna heater. The water is
backed up at the washer installed downstream of the pressure switch (5), leading to a pressure build-up.
Once the pressure rises above 1.2 barg, fragrance dosing is released. The dosing pump (10) doses the set
fragrance quantity from the fragrance container (16) via the dosing valve (7) into the water that is flowing
toward the sauna heater. The splash occurs. At the end of the splash, the solenoid valve closes again. The
pressure switch monitors the pressure reduction in the splash line, which must take place within 3 seconds
after the solenoid valve closes.
If the pressure of 1.2 barg is not reached, or the pressure drops during splash, the message “Water pres-
sure fault” appears, a safety shutdown for the fragrance takes place and the solenoid valve remains open
(see Chapter 7.3, Fault removal). This ensures that the fragrance concentrate can only be dosed when the

Automatic sauna splash system, type Sauna Plus 8 Basic

necessary water pressure is present in the device. This is important because no undiluted fragrance con-
centrate must get onto the sauna heater. This can be flammable!
The built-in safety combination (3) in accordance with DIN EN 1717 (non-return valve + aerator) addition-
ally ensures that no splash water can be sucked back into the piping network in the event of a pressure
drop. The safety combination (3) is preceded by a dirt filter (8) and a ½” shut-off ball valve (9).
ATTENTION!
To avoid dosing on the cold heater, the automatic sauna splash system must be inter-
locked with the sauna control unit on site! If the internal switch-on delay (adjustable)
is activated, it prevents the first splash after the mains connection. If needed, this
switch-on delay can be deactivated.

3.2.1 The dosing unit
Fragrance dosing is performed using a peristaltic pump, which can also
reliably transport the smallest dosing quantities, even when air or gas
bubbles are trapped in the suction line. The rotating rollers press the dos-
ing hose against the wall, which pushes the liquid in the hose out in front
of the rollers while simultaneously sucking more liquid in behind them. It
is exceptionally reliable and also very easy to operate.
Fragrance concentrations may be exceptionally aggressive. The dosing
hose used is resistant to most commercially available concentrates.

The installation of a combined spring-loaded non-return and dosing valve
reliably prevents water from being pushed back or the dosing line from
draining. The valve body is completely made of stainless steel, hose con-
nection 4x1 mm (angular shape) - thread 3/8” AG.
The opening pressure is 0.69 barg.
ATTENTION!
The composition of fragrances varies. This may reduce the service life of the hose in
the fragrance pumps. The fragrance pump must therefore be checked regularly in ac-
cordance with the maintenance schedule, and each time the fragrance is refilled.
3.2.2 Control unit
The control unit consists of a housing with protection class IP44. The electronic components are installed
in the housing. The operating parameters can be set at the control unit.
3.2.3 Piping and fittings
The piping of the automatic sauna splash system consists of a shut-off ball valve (9), a dirt filter (8) and a
safety combination (3), which complies with the DIN EN 1717 regulation when the splash line is draining,
so that no water can be sucked back into the water supply. Furthermore, the piping consists of a shut-off
solenoid valve (4), the splash pipe with integrated washer, a pressure switch (5) for pressure monitoring
and the dosing valve.
3.2.4 Oven shower head (series)
The standard scope of delivery includes a oven shower head consisting
of a stainless steel pipe d 18x200 mm with drill holes that distribute the
water over the heater stones. The oven shower head has a 3/8” interior
thread connection.
3.2.5 Wall bushing (option)
For the installation and secure fastening of the oven shower head, we
offer different wall bushings with 3/8” AG thread connection made of
stainless steel; see Chapter 3.1 Scope of delivery/accessories.
Standard dimensions:
Length before the flange: 190 mm
Length behind the flange: 90 mm
Flange diameter: 60 mm
Other dimensions on request, special versions are possible
3.2.6 Extension (option)
For the installation and secure fastening of the oven shower head, we
offer different extensions with 3/8” x120mm IG-AG thread connection
made of stainless steel; see Chapter 3.1 Scope of delivery/accessories.
