4.4 Mounting the Nordmann AT4 D SPA Display
CAUTION!
The electronic components of the Nordmann AT4 D 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).
4.4.1 Flush mounting
1. At the desired location, mark mounting opening according to the size of the ush-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 ush-mounted housing and insert the connecting cable
(four-wire cable, 0.34 mm2per wire) into the ush-mounted housing. Then, lead the cable through
the wall opening to the steam generator.
Fig. 6: Inserting the connecting cable
3. Insert the ush-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 ush-mounted housing (only necessary with cavity
walls).
Note: in massive walls the ush-mounted housing must be xed either with the screws and dowels
supplied or by using PU mounting adhesive or mortar.

4. Connect the connecting cable to the Nordmann AT4 D SPA display control board according to the
gure below. For this purpose, the individual wires have to be stripped 6 mm and appropriate cable
end sleeves have to be crimped. Then, push the individual wires into the corresponding connection
opening of the terminal plug "X1" until they come to a stop.

5. Connect the connecting cable according to the specications in chapter 4.5 to the Nordmann AT4
D, then perform the function tests.
6. After function tests have been passed carefully place the Nordmann AT4 D SPA Display onto the
ush-mounted housing. Make sure the supply cable is not getting pinched and the that the magnets
in the housing t into the openings of the control board. Then, x the Nordmann AT4 D SPA Display
to corresponding supports of the ush-mounted housing using the four screws supplied.

4.4.2 Surface mounting
1. Using the aluminum surface-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.
• Insert the supplied dowels.
• Fix surface-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:
• Drill 2 holes ø3 mm, depth 35 mm
• Fix surface-mounted housing to the wall using the countersunk screws supplied, align housing
with the help of a spirit level and fasten den screws.
Note: If the mounting location does not permit bolt mounting (e.g. on a glass wall) the aluminum
surface-mounted housing can also be glued over its entire surface to the underground.

4.5 Connecting the SPA Display to the Nordmann AT4 D
Observe and comply with the notes in the installation of the Nordmann AT4 D steam generator
and the local regulation regarding electrical installation when connecting the Nordmann AT4 D
SPA Display to the Nordmann AT4 D steam generator!
DANGER!
Danger of electric hazard!
Before connecting the Nordmann AT4 D SPA Display to the Nordmann AT4 D steam generator
set the steam generator out of operation and disconnect it from the mains!
CAUTION!
The electronic components inside the Nordmann AT4 D steam generator are very sensitive to elec-
trostatic discharge. When the unit is open for installation work, appropriate measures must be taken
to protect these components against damage caused by electrostatic discharge (ESD protection).
1. Remove the front panel of the control compartment of the Nordmann AT4 D.
2. Insert the four-wire connecting cable from the bottom via a cable gland into the control compartment.
Then, connect the cable to terminal "X15" on the power board of the Nordmann AT4 D according to
the wiring diagram shown below.
