4 Installation
4.1 To do before the installation
of the product
• Make sure that you have the necessary installation
accessories:
– Refer to chapter 13 Accessory overview for an over-
view of the accessories.
– If you install the product with free suction or free dis-
charge, it is necessary to install a protection grille.
Make sure that the safety distance agrees with the
standard DIN EN ISO 13857 and the standard DIN
24167–1.
• Examine the packaging for transportation damage and re-
move the packaging from the product carefully.
• Examine the product and all components for damage.
• Make sure that the information on the name plate agrees
with the order confirmation.
• Install the product in a location where there is space for
commissioning, troubleshooting and maintenance.
• Make sure that the installation location is clean and dry,
for full safety during electrical work.
• Make sure that the installation surface has sufficient ca-
pacity to hold the weight of the product.
• Make sure that the duct connection agrees with the air
flow direction of the ventilation system. Refer to the air
flow direction arrows in 4.4.1 Duct connection overview.
• Make sure that all cable glands are tight against the ca-
bles to prevent leaks.
• If possible, do not put the product directly against the wall.
If the product is to be installed directly against the wall, put
insulation on the wall to decrease vibrations and unwanted
noise.
• If the product is installed in an outdoor environment, do
not let the product be out of power.
• Obey local laws and conditions for installation.
• Make sure that all equipment is supplied with product.
• Put the outdoor air intake on the northern east side of the
building, away from other exhaust outlets.
• Install the loose parts from the cardboard box in the
product.
• If the product is set to OFF for a long time after the product
is installed, operate the product for 15 minutes or more
each day. If the product is not operated each day, it can
cause damage to the motor bearings.
Caution
If the product is not operated each day, it
can cause damage to the fan motor
bearings.
• If the product is installed outside and is not in operation,
put protection from condensation on the product.

4.4 To connect the ducts to the
product
Warning
Rotating fan impeller. Make sure that the
product is not energized until all the ducts
are connected or protected with a grille.
1For products with circular duct connections, do these
steps:
