• Read this manual and make sure that you understand the instructions before you do work on the product. • Obey local conditions and laws. • The ventilation contractor and the operator are responsible for correct installation and intended use. • Keep this manual at the location of the product. • Do not install or operate the product if it is defective. • Do not remove or disconnect safety devices. • Make sure that you can read all warning signs and labels on the product when it is installed.
4 4 Installation 4.1 To do before the installation of the product • Make sure that you have the necessary installation accessories: 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 – Refer to 13 Accessory overview for an overview of the accessories.
5 Electrical connection 5.6 5.1 To do before the electrical connection • If the product has an built in motor protection, reset by disconnecting the product from power for 60 seconds. • 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.
6 Commissioning 7 Operation Caution 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. 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.
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. 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.
