Installation/English
Installation preparation (A-C)
Detach the motor unit by grasping it as shown
in Figure (A). Pry off the motor unit by leveraging
against the cover with your knuckles. Ensure that
you have the motor unit in a secure grip so you do
not drop it when it is detached.
Then detach the wall frame by using a screwdriver
to press the lock button as shown in Figure (B).
Then remove the top of the cover from the wall
frame as shown in Figure (C).
New installations (D-J)
New installations require holes using a Ø110 mm
hole saw (Figure D).
Pax wall pipes and external louvres are available
as accessories (Figure E). The fan’s wall seal has a
short spigot which fits inside the Ø100 mm pipe.
Make sure when mounting to adapt the length of
the wall pipe so it does not push back the wall seal
so the fan impeller cannot rotate. Always custo-
mise a wall pipe, existing or new, so it ends about
5 mm inside the wall surface where Norte is to be
installed. The wall frame with its seal is prepared
with 5 cable entry points (Figure F) for concealed
electrical connection or surface-mounted cable
using the dimension shown in Figure G.
Make sure that the seal is properly installed on the
wall frame; place it in the appropriate place and
centre it in the wall pipe. The wall frame can be
levelled horizontally by placing a spirit level on its
support points (Figures H and I).
Mark the three attachment points for the appropri-
ate screws to the substrate (Figure J).
Pax follows industry regulations for Safe Water
installation, drilling and sealing with silicone
according to the instructions for wooden walls and
concrete. These must be followed. (See page 31).
Tighten the screws so that the seal forms a seal
against the wall.
Always use a qualified electrician. (K-N)
All 100–240 V electrical connections must be per-
formed by a qualified electrician. The power must
be cut during all electrical work on the product.
The wall frame contains an electronics component
with terminal blocks for 100–240 V AC and 12 V DC.
Electrical connection can be made according to
the wiring diagram on page 8.
NB: As the two legs of the motor unit protrude into
the wall frame, and one leg is in contact with the
switching contact, cables must be laid in the wall
frame as shown in Figures K/K1 (100–240 V AC
connection) and L (12 V DC connection), so that no
cables block the path of the leg.
Mounting the cover on the wall frame (O-S)
The fan is double insulated and must not be
earthed. When the electrical connection has been
completed, place the cover back over the wall fra-
me by fitting the hook in the wall frame in the hole in
the cover (Figure O).
Next, close the cover over the wall frame (Figure
P). Ensure the catch the screwdriver is pointing to
(Figure Q) engages properly.
Make sure that the cover is firmly seated in the
hook on the wall frame and latch by gently pulling
the cover.
Finally, put the motor unit in place (Figure R). Be ca-
reful when putting the motor unit in place. The legs
and the impeller can be damaged if the unit is for-
ced in at an angle. A distinct ‘click’ sound confirms
that the unit is in place. Check that the impeller
rotates freely before switching on (Figure S).
Automatic functions and
settings via app
Basic setting:
Pax Norte is programmed to cope with the vast
majority of installations.
The fan works continuously with a basic flow of
approximately 30 m³/h. When the light changes,
when a light is switched on or when shadows
change when someone moves in the room, the
flow increases to approximately 60 m³/h.
If the humidity rises rapidly, for example when
the shower is on, the fan goes up to maximum
flow at approximately 95 m³/h.
When the humidity has been removed, the fan re-
verts to the basic flow of approximately 30 m³/h.
If other settings or functions are desired, down-
load the Pax app from the App Store or Google
Play.
