5.1 Safety notes on mounting and installation work
Qualication of personnel
All mounting and installation work must be carried out only by well qualied specialists authorised by
the owner. It is the owner’s responsibility to verify proper qualication of the personnel.
General notes
Strictly observe and comply with all information given in the present installation manual regarding the
mounting of the unit and the installation of water, steam and electricity.
Observe and comply with all local regulations dealing with water, steam and electrical installations.
Safety
Some installation work requires removal of the unit covers. Please note the following:
DANGER!
Danger of electric shock!
The Condair RM is mains powered. Live parts may be exposed when the unit is open. Touching
live parts may cause severe injury or danger to life.
Prevention: The Condair RM must be connected to the mains only after all mounting and installation
work has been completed, all installations have been checked for correct workmanship and the unit
is closed and properly locked.
CAUTION!
The electronic components inside the steam humidier are very sensitive to electrostatic
discharge.
Prevention: To protect these components against damage caused by electrostatic discharge (ESD
protection) appropriate measures must be taken when the unit is open for installation work.
VORSICHT!
The Condair RM with SPA control is not splash-proof (IPX4).
Prevention: The Condair RM with SPA control must therefore not be used for prefabricated sauna
cabins.

18 Mounting and installation work
The installation site of the Condair RM depends largely on the location of the steam distributor. To ensure
proper functioning of the steam humidier and to obtain an optimal efciency, the following points
must be considered and observed when choosing the location for the steam humidier:
– Install the steam humidier so that:
– the length of the steam line is kept as short as possible (max. 4 m),
– the minimum bend radius for steam hoses (R= 300 mm) and for solid steam pipes (5 x
internal diameter) and the minimum upslope/downslope of 15 % (8.5°) of the steam hose is
maintained (see chapter 5.4.4).
– The Condair RM is designed for wall-mounting or oor mounting (with the optional oor supports)
in protected interiors. Make sure that the construction (wall, pillar, oor-mounted console, etc.) to
which or on which the steam humidier is to be mounted, offers a sufciently high load-bearing
capacity (take notice of the weight information found in the dimensions and weights table after Fig.
3), and is suitable for the installation.
– The back panel of the Condair RM retains heat during operation (max. surface temperature of the
metal housing approx. 60 - 70 °C). Make sure, therefore, that the construction (wall, pillar, etc.) to
which or on which the unit is to be mounted, does not consist of heat-sensitive material.
– Install the Condair RM in such a manner that it is freely accessible with sufcient space available
for maintenance purposes. The minimum distances shown in Fig. 3 must be maintained.
– The Condair RM is protected according to IP20. Make sure the unit is installed in a drip-proof loca-
tion and the admissible ambient conditions are complied with.
– Do not mount the Condair RM to hot or very cold walls or near vibrating components.
– The steam humidier Condair RM must only be installed in rooms with a oor drain.
CAUTION!
If for some reason the Condair RM must be installed in a location without oor drain, it is manda-
tory to provide a leakage monitoring device to safely interrupt the water supply in case of leakage.
– When mounting the Condair RM use only the mounting materials supplied with the unit. If mount-
ing with the materials supplied is not possible in your particular case, select a method of mounting
that is of similar stability.
– The Condair RM is designed for installation and operation within buildings (admissible temperature
range 5...40 °C). For outdoor operation the Condair RM must be placed in a weather protective hous-
ing. If ambient temperatures near or below the freezing point have to be expected, the protective
housing must equipped with a thermostat controlled heating of sufcient capacity. The water supply
pipe must be equipped with a trace-heating and must be insulated up to the protective housing.
The installation of a normally open valve inside the building envelope that will drain water in case of
power failure is highly recommended.

20 Mounting and installation work
Procedure
1. Mark the attachment points "A" at the desired position with the help of a spirit level. Then, drill holes
diameter: 8 mm, depth: 40 mm.
2. Insert the supplied plastic plugs. Then, screw in the supplied screws 5 x 40 mm into the plastic plug
in such a way that the distance between screw head and unit rear wall is 10 mm.
3. Unlock the retaining screw of the unit cover, then remove the unit cover.
4. Remove transport securing device located on top of the steam tank , disconnect all heating cables
and the connecting cables to the over temperature switch(es). Then, pull steam tank out of the cou-
pling sleeve and remove.
5. Carefully pull the xing clip of the lling cup out of the support, then push lling cup down and pull it
to the front out of the support.
6. Hang the steam humidier onto the screws. Insert the supplied locking plates "B" between screw
head and unit rear wall. Align the steam humidier horizontally using a spirit level, then fasten the
screws.
7. Moisten the O-ring in the steam tank receptacle with water (do not use grease or oil). Then, insert
the stirrup on the backside of the steam tank into the retaining bracket on the back wall of the unit
housing. Insert the connector on the bottom side of the steam tank into steam tank receptacle and
push steam tank downwards until it comes to a stop.
Important: Check whether the steam tank is correctly hooked in the retaining bracket on the back
wall of the unit housing by pulling the steam tank to the front. A correctly mounted steam tank can-
not be moved.
8 Connect heating cable plugs into the corresponding sockets (see Fig. 5).
Important: make sure the cables are not crossed!
Attach connecting cable to the connector of the overtemperature switch.

9. Insert the hocks of the lling cup into the opening in the lling cup support. Push lling cup upwards
until the xing clip engages.
Important: make sure the drain hose from water cup is inserted into the drain opening on the
bottom of the unit housing.
10. Reattach the unit cover and secure it with the retaining screw.
