4.3 NotesonpositioningtheNordmannSPADisplays
Please observe the following notes for the correct positioning of the Nordmann SPA Display(s):
– The Nordmann SPA Display(s) must not be installed in hazardous locations and in rooms where
water splashes may occur.
– Do not mount the Nordmann SPA Display(s) inside the steam bath cabin, sauna, bio sauna, etc..
– If possible mount the Nordmann SPA Display(s) at eye level.
– Do not mount the Nordmann SPA Display(s) in exposed places.
– Do not mount the Nordmann SPA Display(s) on vibrating components.
– Place the Nordmann SPA Display(s) in such a way, that the total length of 50 m of the CAN BUS
cables with which the Nordmann Omega or the Condair Delta SPA Control Box and the Nordmann
SPA Display(s) are interconnected is not exceeded.
4.4 MountingtheNordmannSPADisplay
CAUTION!
The electronic components of the Nordmann SPA Display are very sensitive to electrostatic discharge.
For all installation work on equipment appropriate measures must be taken to protect these components
against damage caused by electrostatic discharge (ESD protection).
Note: the Nordmann Omega or the Condair Delta SPA Control Box, respectively and the Nordmann SPA
Display(s) (up to a max. of 8 SPA Displays) are interconnected via a so-called CAN BUS. Use only a
shielded four-wire cable with a cross section of 0.34 mm2per wire to establish the CAN BUS con-
nections. The total length of the CAN BUS must not exceed 50 m.

4.4.1 In-wallmounting
1. At the desired location, mark mounting opening according to the size of the in-wall mounted housing
with the help of a spirit level, then ream out the mounting opening.
Important: the mounting opening must be reamed out exactly since the decoration cover (broken
line in Fig. 5) overlaps the mounting opening on the right side only 4 mm, on the left side only 9 mm
and on the top and bottom side only 8.5 mm.

2. Knock out the desired cable entry of the in-wall mounted housing and insert the CAN BUS cable
(shielded four-wire cable, 0.34 mm2per wire) into the in-wall mounted housing. Then, lead the cable
through the wall opening to the steam generator or to the Condair Delta SPA Control Box.

3. Insert the in-wall mounted housing into the wall opening, align it with the help of a spirit level, then x
it with the four fastening claws attached to the in-wall mounted housing (only necessary with cavity
walls).
Note: in massive walls the in-wall mounted housing must be xed either with the screws and dowels
supplied or by using PU mounting adhesive or mortar.

4. Free the shielding of the CAN BUS cable(s) by removing the insulation from the appropriate clamp-
ing position to the end of the cable. Remove the exposed shielding to about 2 cm, then x the end
of the remaining shielding with a piece of shrink tubing as shown in Fig. 8 and secure the exposed
shielding with the shielding clamp(s) to the housing.

5. Connect the supplied CAN BUS connecting plug to the CAN BUS cable from the Nordmann Omega,
Condair Delta SPA Control Box or from another Nordmann SPA Display as shown below. For this
purpose, strip the individual cable wires of the CAN BUS cable 6 mm, crimp the suitable wire end
ferrules and insert the cable wires as far as possible into the correct connection opening of the sup-
plied CAN BUS connecting plug. Then connect the CAN BUS connecting plug to the adapter cable
(ex factory connected to terminal "X3").

A CAN BUS cable to another Nordmann SPA display is connected either directly or via another
adapter cable (available as an accessory) to the unused terminal "X2" (see notes in chapter 4.5).
Important: If two CAN BUS cables are connected to the Nordmann SPA Display board, jumper "JP1"
(terminator) on the Nordmann SPA Display must be removed.

6. Connect the CAN BUS cable according to the specications in chapter 4.5 to the Nordmann Omega
or the Condair Delta SPA Control Box, then perform the function tests of the Nordmann Omega SPA
Display.
7. After function tests have been passed carefully place the Nordmann SPA Display onto the in-wall
mounted housing. Make sure the supply cable is not getting pinched. Then, x the Nordmann SPA
Display to corresponding supports of the in-wall mounted housing using the four screws supplied.

9. Finally attach the decoration cover (the decoration cover is held by the magnets in the in-wall mounted
housing), and seal the gap between the decoration cover and the wall splash-proof with silicone.

4.4.2 On-wallmounting
1. Using the aluminum on-wall mounted housing as template mark the two xing holes at the desired
location, with the help of a spirit level. Then proceed as follows:
– for the mounting on a stonework wall:
• Drill 2 holes ø6 mm, depth 35 mm.
– for the mounting on a wooden wall:
• Drill 2 holes ø3 mm, depth 35 mm
Note: If the mounting location does not permit bolt mounting (e.g. on a glass wall) the aluminum on-
wall mounted housing can also be glued over its entire surface to the underground.
If the CAN BUS cable is routed in-wall to the mounting point, an cavity of 40 mm x 80 mm (centered
on the drill holes) with a minimum depth of 30 mm must be provided for the shielding clamps.

2. Free the shielding of the CAN BUS cable(s) (shielded four-wire cable, 0.34 mm2per wire) by removing
the insulation from the appropriate clamping position to the end of the cable. Remove the exposed
shielding to about 2 cm, then x the end of the remaining shielding with a piece of shrink tubing as
shown in Fig. 15 and secure the exposed shielding with the shielding clamp(s) to the housing.

3. Mount the on-wall mounted housing to the wall:
– for the mounting on a stonework wall:
• Insert the supplied dowels.
• Fix on-wall mounted housing to the wall using the screws supplied, align housing with the
help of a spirit level and fasten den screws.
– for the mounting on a wooden wall:
• Fix on-wall mounted housing to the wall using the countersunk screws supplied, align hous-
ing with the help of a spirit level and fasten den screws.

4. Connect the supplied CAN BUS connecting plug to the CAN BUS cable from the Nordmann Omega,
Condair Delta SPA Control Box or from another Nordmann SPA Display as shown below. For this
purpose, strip the individual cable wires of the CAN BUS cable 6 mm, crimp the suitable wire end
ferrules and insert the cable wires as far as possible into the correct connection opening of the sup-
plied CAN BUS connecting plug. Then connect the CAN BUS connecting plug to the adapter cable
(ex factory connected to terminal "X3").
