IMPORTANT NOTE! Note the following prior to installation:
• Avoid sharp bends or right angles in the steam pipe.
• Do not direct the steam jet against walls, seats or other objects.
Keep a minimum of 700mm away from the steam nozzle.
• "Pockets of water" must not develop in steam and/or ventilation pipes.
IMPORTANT NOTE! The flow rate inside the steam pipe must not be
restricted (by a tap or valve). The inner diameter of the steam pipe must
not be reduced in size in any way.
• In steambath rooms that operate continuously for more than two hours,
the air must be changed at a rate of 10-20m³ per person per hour.
• The power supply cable to the steam generator must always be live.
Do not connect any switches or similar devices to this cable.
• Outlet pipes between the steam generator and the waste water outlet
must always be sloping downwards.
• The ambient temperature outside the vapour chamber and around the
steam generator must not exceed 35 °C.
• Mount the feeler gauge diagonally as far away as possible from the
steam outlet (at a height of 1500-1700mm).
• Descale the steam generator regularly according to the "Descaling"
section of the instructions.
• Clean the steambath cubicle regularly. See section "Cleaning the
steambath cubicle".
• CAUTION! The waste water from the steam generator must always
be routed into a waste water outlet outside the steambath cubicle.
The waste water outlet must be designed to withstand 100° C hot water.
The escaping water is hot. If the water hardness exceeds 5° dH, a water
softener must be used.
• Vacant tubes EN21 must be used for the cables from the control unit to
the steam generator, see fold-out page I, Fig. [1]. These vacant tubes
are not included in the delivery specification.
• All cables must be pulled through using a pulling device to avoid damage.
• If there are more than four bends in a vacant tube, the cables must be
pulled through the tube prior to installation.
• The enclosed 5m cable is suitable for vacant tubes up to 4.5m.
The special accessory 47 837 can be used once per supply line for
vacant tubes up to 9.5m.
• The device must be disconnected from the power supply prior to
maintenance work.
• Caution! Hot steam in the area around the steam outlet.
Steambath cubicle
The steambath cubicle must only be heated using the steam generator.
The ambient temperature around the steambath cubicle and steam
generator should not exceed 35 °C. If there is a sauna next to the
steambath cubicle, it must be heat-insulated. There must be a minimum
air gap of 100mm separating the walls of the sauna and the steambath
cubicle.
Steam generator
Fitting and connection, see fold-out page I, Fig. [2].
• The steam generator must be installed in a position high enough to
ensure that the downward gradient of the outlet pipe leading to the
waste water outlet is sufficiently steep. The steam generator must be
mounted on the wall holders provided.
Please pass these instructions on to the fitting user!
The right to make technical modifications is reserved!
• The steam generator must be installed by an authorised electrician.
The steam generator connections are permanent. The generator is
A
installed outside the steam cubicle as close as possible to the control
1
unit (a maximum of 5m away on the same floor or a maximum of 3m
2500 V
away on the floor above or below).
100 °C
• The steam generator must be installed in a dry and ventilated room with
a waste water outlet on the same floor as the steambath cubicle or one
floor above or below. (Never install the generator directly above a waste
water outlet or in an aggressive environment).

Pipe installation

The pipes must always be installed by a qualified installer.
Water connection, see fold-out page I, Fig. [3].
1.Select a pressure-reducing valve (A) or (A1) according to local and
national regulations, see fold-out page I, Fig. [3].
2.Connect a water line with a minimum internal diameter of 12mm
to the pressure-reducing valve (A)/(A1) and with a maximum water
temperature at the inlet of 40 °C. Warm water accelerates the
heating process.
3.Establish a connection between the pressure-reducing valve (A)/(A1)
and steam generator using the hose provided (B).
Never reuse old hose sets!
IMPORTANT NOTE! Before connecting the water supply, carefully flush
out the pipes to the steam generator (observe EN 806) to prevent metal
chips or other foreign bodies from entering the steam generator lines.
Steam pipe installation, see fold-out page I, Fig. [4].
• Connect a copper pipe with a minimum inner diameter of 12mm
(not included in the delivery specification) to steam outlet (C) on the
connecting piece. The steam pipe leading to the steam generator
must be perfectly horizontal.
IMPORTANT NOTE! The pipes between the steam generator and the
steambath cubicle must not contain any "pockets of water" or bends
where steam can condense and accumulate as water, see fold-out page I,
Fig. [4].
The steam pipe should have as few bends as possible. The bends should
curve gently and have a minimum radius of 50mm. The pipes must not
contain any sharp kinks.
IMPORTANT NOTE! The flow rate inside the steam pipe must not be
restricted (by a tap or valve). The inner diameter of the steam pipe must
not be reduced in size in any way.
All steam lines must be insulated from end to end to protect against burns.
Floor, waste water outlet and ceiling
A waste water outlet designed to withstand the total flow rate of the
consumer devices must be installed in the steambath cubicle. The floor
must slope towards the waste water outlet. Suitable floor coverings
include bonded plastic coverings, stone slabs, etc. The requirements for
the consistency of the substrate, connections, etc. are the same as those
of a shower cubicle. If a ceiling shower is to be installed in the steam
bath cubicle, sufficient ventilation must be provided for the space
above the ceiling shower. To avoid damage to the building structure,
an additional coat of moisture-proof finish must be applied to all
surfaces.
CAUTION! Plastic floor and wall materials located under the steam nozzle
may change colour after coming into contact with steam and hot water.
Waste water outlet
Waste water outlet from steam generator, see fold-out page I, Fig. [4].
1.Connect the outlet pipe (copper pipe with a minimum inner diameter
of 12mm, not included in the delivery specification) to the connection
(G½") on the steam generator.
2.Route the outlet pipe to the nearest waste water outlet outside the
steambath cubicle. The temperature of the waste water is approx. 95 °C.
IMPORTANT NOTE! Shutting off the waste water pipe (e.g. with a tap
or similar) is not permitted.
The outlet pipe from the steam generator to the waste water outlet must
slope downwards regardless of the position of the waste water opening.
The steam generator must be mounted on the wall holders provided.
