4 Installation
4.1 To do before the installation
of the product
• Make sure that you have the necessary installation
accessories:
– Refer to 13 Accessory overview for an overview of the
accessories.
– To decrease vibrations transmitted from the product to
the duct system, Systemair recommends to install vi-
bration dampers, fast clamps or flexible connections.
– 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.
• Use installation material with fire resistance rating for the
installation location.
• 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 motor effect and the fan performance
agrees with the expectations at the installation location.
• Make sure that the information on the name plate and the
motor name plate agrees with the operation conditions.
• 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.
• Refer to the airflow direction arrows on the name plate or
on the product to install the product in the correct position.
• Make sure that all cable glands are tight against the ca-
bles to prevent leaks.
4.2 To install the product
1 Remove the screws on the side of the casing and re-
move the front of the casing from the product. Keep the
screws for when the casing is to be attached again.
2 Make a hole (C) in the wall for the duct and the electric
cable. Make sure that the diameter of the hole is suffi-
ciently large for the duct and the fast clamp.

3 Push the duct (D) and the electric cable through the hole
in the wall from the outside. Make sure that the length of
the duct is sufficient.
4 Connect the product (E) to the duct. Use the fast clamp
to attach the duct to the product. Systemair recommends
to use a FK fast clamp to attach the duct to the product.
The FK fast clamp are available as an accessory.
Refer to 13 Accessory overview.
5 If you install the product near a duct bend, do these
steps to prevent vibrations, unwanted noise and de-
creased air pressure:
a. Measure the distance (A) between the product and
the duct bend.
b. Make sure that the distance (A) is a minimum of 2.5
x the diameter (B) of the duct system. For circular
ducts, (B) is the nominal diameter. For rectangular
ducts, (B) is the hydraulic diameter.

6 Tighten the fast clamp around the duct and the product
with the supplied screws. Make sure that there is a dis-
tance between the duct and the product to decrease vi-
brations transmitted from the product to the duct system.
7 Use the supplied screws and plugs to install the product
vertically onto the outside wall.
8 Do the electrical installation. Refer to 12.3 Wiring
diagrams.
9 Attach the front of the casing with the screws.
