3 Transportation and storage Warning Make sure that the product does not become damaged or wet during transportation. A damaged or wet product can cause fire or electric shock. 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 page 17 for an overview of the accessories. • Before you move the product to the installation location, examine the packaging for damages.
4.2 1 2 To install the product Put the product in the correct position: a. Install the product with accessories that decrease vibrations in the product and the duct system. a. Install the product with the motor up or to the sides. If you install the product vertically, install mounting rings (A) against the ceiling and use flexible connections (B): B 135° 135° 45° 45° Caution A Do not install the product with the motor down. Dirt can collect in the fan housing. b.
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. A 5 Electrical connection 5.
5.6 To install motor protection for AC motors 6 Commissioning Caution • If the product has an built in motor protection, reset by disconnecting the product from power for 60 seconds. • 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.
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. 7.1 To start a product with an EC motor 1 Make sure that the 0–10 V signal is set to “0” with the speed controller. 2 Set the installed safety switch in the ON position and wait 5 seconds.
8 Maintenance Warning Set the installed safety switch in the OFF position before you do the maintenance unless the instructions tell you differently. Make sure that the safety switch is not accidentally set in the ON position. 8.1 Maintenance schedule The intervals are calculated from continuous operation of the product. Maintenance task Usual operation conditions Each 6 months Each year Unusual operation conditions.
9 Troubleshooting Note: If you cannot find a solution to your problem in this section, speak to Systemair technical support. Problem Cause Solution The fan impeller is not correctly balanced. Speak to Systemair technical support. There is dirt on the fan impeller. Clean the fan impeller carefully. Refer to 8.2 To clean the product page 9. The fan impeller has damages or deformations because the transported air contains aggressive media. Speak to Systemair technical support.
Problem Cause Solution The fan impeller does not turn in the correct direction. Make sure that the electrical connection is correctly done. A phase loss occurred. If the motor is a 3-phase motor, make sure that no phase is missing. Note: This is not applicable for EC motors. The motor is overheated. Thermal contacts, PTC or resistors are released. • Do a check of the motor cooling impeller. • If it is possible, measure the resistance to do a check of the motor winding.
10 Disposal The product follows the WEEE directive. This symbol on the product or the packaging of the product shows that this product is not domestic waste. The product must be recycled at an approved disposal location for electrical and electronic equipment. 11 Warranty For warranty claims, send a written maintenance plan and the commissioning report to Systemair. The warranty is only applicable for these conditions: • The product is correctly installed and operated. • Motor protection is used.
