11 User and installation guide
The Pax Passad series, are designed to boost
the basic ventilation of a house * and for forced
venting of humidity and odours from wet areas
(WC/bath/shower/laundry).
The fans can, depending on which model, be
fitted in ducts with natural draught (ceiling,
Figure 1) or without natural draught (wall, Figure
2) **. The fan fits ducts with a diameter of Ø or
100 – Ø140 mm. or larger ducts (up to 160 mm
diameter) the Pax cover plate (accessory) must
be used.
To ensure that the Pax Passad does not affect
other ventilation systems and is not affected
by them, the fan must always be installed in its
own duct. Make sure that the duct is clear of ob-
structions. Avoid insect mesh, filters and other
objects that may obstruct the flow of air.
To prevent condensation in natural draught
ducts (in winter), the ducts must be insulated
where they pass through unheated areas such
as cold attics.
If the fan is connected to a duct with natural
draught ventilation, the backdraught shutter
must be removed and replaced with the PAX
passad nose cone accessory (see figure 1).
NOTE: A backdraught shutter is harmful if the
fan is installed in a ventilation duct with natural
ventilation.
The fan is designed for use in a temperature
range of 5 to 35 °C. If the fan is installed in a cold
area or if it has been stored in a cold place before
installation, it may run slowly when started for
the first time. The fan will work normally when it
reaches its working temperature.
Make sure that air can enter the bathroom, for
example through a large gap at the door or by
using the Pax transfer air unit (accessory).
We recommend the use of genuine Pax acces-
sories to ensure that the fan works properly and
delivers the correct capacity.
* Primarily detached houses and holiday homes, but can
also be used in multi-dwelling buildings with separate
ventilation ducts.
** With natural draught ventilation, air is carried upwards
through ventilation ducts and out of the building (see
Figure 1).
For natural draught ventilation to work, the air inside the
building must be warmer (and therefore lighter) than the
air outside. Natural draught ventilation therefore works
best during the winter. Natural draught ventilation will be
reduced or absent if the temperature differential (inside/
outside) is small or non-existent. For this reason, buildings
are often poorly ventilated when the weather is warm.
Thank you for choosing
