– To decrease vibrations transmitted from the product to the duct system, Systemair recommends to install vibration dampers, fast clamps or flexible connections.
– If you install the product with free suction or free discharge, 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 remove 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 capacity 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 cables to prevent leaks.

4.2 To install the product

Install the product on the mounting feet. Make sure that the weight of the product is equal on the mounting feet. Make sure the drain plug is always put at the lowest point of the product to drain the condensation.

Caution
Risk of damage to the product if there is much water that cannot drain.

2 If wall brackets are used, install the wall brackets.

Note:
Wall brackets for installation on walls are available as accessories.

3 Connect the ducts to the product, refer to 4.2.1 To connect the ducts to the product.

4.2.1 To connect the ducts to the product
1 Put the ducts on the duct connections of the product.

Note:
Systemair recommends to use flexible connections or FK fast clamps to attach the duct to the product. Flexible connections and FK fast clamps are available as accessories.

2 Tighten the fast clamps around the duct and the product with the screws that are supplied with the fast clamps.
Make sure that there is a distance between the duct and the product to decrease vibrations transmitted from the product to the duct system.
3 If you install the product near a duct bend, do these steps to prevent vibrations, unwanted noise and decreased 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.

5 Electrical connection

5.1 To do before the electrical connection

Make sure that the electrical connection agrees with the product specification on the motor name plate.
Make sure that the environment for electrical connection is clean and dry.
Make sure that the wiring diagram that is included with the supply of the product agrees with the terminals in the connection box.

5.2 To connect the product to the power supply

Complete the electrical connection for the motor. Refer to the motor wiring diagram that is included with the product.
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 installation, 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 product has a frequency converter, uninterruptible power supply (UPS), or an EC motor. EC motors have a leakage current to earth that is <=3.5 mA.

5.3 Speed controller for EC motors

EC motors are controlled through a stepless 0–10 V signal.
Do not use power supply for the speed controller.
Refer to 12.3 Wiring diagrams and the instruction manual for the external speed controller.

5.4 Motor protection for EC motors
EC motors have an integrated motor protection. Reset the motor protection by disconnecting the fan from power supply for 60 seconds.

5.5 Speed controller for AC motors
Note:
The speed controller alternatives are different for different motor types. Make sure that your motor is compatible with the speed controller type before you use it.
The speed can be controlled with a frequency converter if the installed frequency converter has built in all-pole sine filter and shielded cables are not needed.

5.6 To install motor protection for AC motors

If the product has an built in motor protection, reset by disconnecting the product from power for 60 seconds.
If the motor has temperature monitors such as thermal contacts (TK) or thermistors lead out into the terminal box, these must always be connected in the control circuit using appropriate motor protection.
Make sure that an overheated motor cannot start again automatically when it becomes cool.
Install the motor cables and the temperature monitor apart.
If the motor does not have temperature monitors, install a motor protection switch.

6. Commissioning

Caution

If strong vibrations occur during commissioning, immediately increase or decrease the fan speed until the vibrations are decreased. Continuous strong vibrations can cause damage to components.
Do not increase the fan speed to a higher rpm value than the maximum value that is given on the name plate.
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.

6.2 To do the commissioning

Set the installed safety switch in the OFF position.
If it is possible to get access to the fan impeller, do the steps that follows:
a. If it is necessary, remove parts of the installation.
b. Turn the fan impeller by hand and make sure that it turn easily.
c. Record the result in the commissioning report.
Make sure to turn the product in a direction that agrees with the related arrow on the product.
a. Record the result in the commissioning report.
If you removed parts of the installation to get access to the fan impeller, install the removed parts again.
Set the installed safety switch in the ON position.
Start the product.
Set the minimum operation speed.
Increase the operation speed gradually to the maximum operation speed.
a. Examine the vibrations in the casing and the bearing areas at all speed levels.
b. Make sure that the vibrations agree with the specifications
in DIN ISO 14694.
c. Make sure that none of the speed levels cause unwanted noise in the product.
d. Record the result in the commissioning report.
Record the necessary data in the commissioning report.

7. Operation

Caution
EC motors must be set to ON/OFF via the control input. To stop the product via mains supply decreases the life time of the motor. Systemair recommends to install external speed controller for easy access to control the input signal.

Make sure that the 0–10 V signal is set to “0” with the speed controller.
Set the installed safety switch in the ON position and wait 5 seconds.
Adjust the fan speed with the 0–10 V signal speed controller.

If an external speed controller is not installed, adjust the fan speed directly with the integrated potentiometer.

7.2 To start a product with an AC motor

Set the installed safety switch in the ON position.
Install the external speed controller. Refer to the instruction manual for the installed speed controller.
