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 4.3.1 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.
• If a product with bypass damper is installed in lower tem-
peratures than -5 °C, use the stop defrost function or in-
stall a pre-heater in the outdoor duct.
• 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 located in one of the ducts.
4.2 To install the product
Warning
Use equipment suitable for work at
height, and make sure that there is suffi-
cient space for the operation.
1Install threaded bars with a dimension of minimum M8 in
the ceiling. Threaded bars and nuts are not supplied by
Systemair. Make sure that the installation equipment can
hold the weight of the product.
6

2Attach the threaded bars and the enclosed washers (A)
to the mounting brackets on the product casing.
A
3Install the product with 1-3° lean in the direction to the
drainage connections (B).
B
4The drainage connection is covered with transport
protection.
Note:
A water-lock kit and a drain pump are available as
accessories.
• If a water-lock kit or a drain pump is used, remove the
protection from the drainage connection.
• If no drainage equipment is used, seal the drainage
connection carefully.
4.3 To connect the product to the
ducts
Warning
Rotating fan impeller. Make sure that the
product is not energized until all the ducts
are connected or protected with a grille.
1Systemair recommends to install the ducts together with
flexible connection DS. Use guide rails to install the flexi-
ble connection on the duct joints. Guide rails are not sup-
plied by Systemair.
2If 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.

4.4 To install the supply air
sensor
1If a heater or cooler is used, install the heater or cooler.
Make sure that the distance between the supply air sen-
sor and the heater is a minimum of 1.5 m.
2Use a drill to make a hole for the supply air sensor in the
supply air duct. Make sure that the distance (A) between
the hole and the product is 3 m.
Note:

3Install the supply air sensor in the hole with the supplied
screws.
4Pull the cable from the supply air sensor to the control
unit CU27–C2 in the electrical cabinet.
4.5 To put insulation on the ducts
If the product is installed in areas with low outdoor tempera-
tures, put insulation on the duct to prevent condensation.
1Put a minimum of 100 mm insulation on the outdoor air
duct and exhaust air duct.
Caution
Use more insulation in areas with very
low outdoor temperatures. There is a risk
of condensation if the insulation is not
sufficient.
2Put insulation on the supply air duct and extract air duct.
3Make sure that there is insulation near the duct joints of
the product.
4Install a protection grille on the exhaust outlet if there is
risk of injury on the fan impeller.
Warning
Rotating fan impeller. Make sure that the
product is not energized until all the ducts
are connected or protected with a grille.
4.6 To connect the water heating
coil
Caution
Be careful when you connect water pipes.
There is a risk of damage to the material
of the water heating coil.
8

Note:
A frost protection sensor and a venting nipple is installed
on the water heating coil.
This instruction is only applicable to products supplied with
built-in water heating coil.

5.1 To do before the electrical
connection
• Make sure that the electrical connection agrees with the
product specification on the name plate.
• Make sure that the environment for electrical connection
is clean and dry.
• Make sure that the wiring diagram agrees with the termi-
nals in the electrical cabinet and in the control cabinet. Re-
fer to the wiring diagram that is found through the
scannable code on the product name plate, or at www.sys-
temair.com.

5.2 To connect the product to the
power supply
• Complete the electrical connection for the product. Refer
to the wiring diagram that is found through the scannable
code on the product name plate, or at www.systemair.com.
• Make sure that the cross section of the protective earthing
is equal to or larger than the cross section of the phase
conductor.
• Install a circuit breaker in the permanent electrical installa-
tion, with a contact opening of a minimum 3 mm at each
pole.
• If a residual current device (RCD) is installed, make sure
that it is an all-current sensitive RCD. Consider if the prod-
uct has a frequency converter, uninterruptible power sup-
ply (UPS), or an EC motor. EC motors have a leakage
current to earth that is <=3.5 mA.
• Loosen the 4 screws for the hatch to the electrical cabinet
and remove the hatch.
• Pull the power supply cable through the cable grommet
(A) and connect the mains power supply to the correct ter-
minals. Refer to the wiring diagram.

6 Commissioning
The commissioning report is found at www.systemair.com.
6.1 To do before the
commissioning
• Make sure that the installation and electrical connection
are correctly done.
• Visually examine the product and accessories for damage.
• Make sure that the safety devices are correctly installed.
• Make sure that there are no blockages in the air inlet and
the air outlet.
• Make sure that installation material and unwanted objects
are removed from the product and the ducts.
• Make sure that the product lean with 1-3° towards the
drainage connection.
• Close the product doors.
6.2 To do the commissioning
1Airflow reduction in bypass defrosting is preconfigured to
50% of the nominal airflow. If the setting of the nominal
airflow is reduced, it will have effect on the airflow over
the electric heater in bypass defrosting. Make sure that
the airflow is above 1.5 m/s over the electric heater.
2Record the necessary data in the commissioning report.
