1 Introduction 1.1 Product description The product is a roof fan with an EC motor or an AC motor, and a tilting mechanism for easy maintenance. The TFSK fans, TOE fans, TOV fans, and TFE fans are supplied with a square base plate. The TFSR fans are supplied with a circular base plate. The EC fans have an internal potentiometer for speed control during continuous operation. The internal potentiometer is installed on the terminal block from the factory.

2.2 Safety instructions Warning Read the warning instructions that follow before you do work on the product. • 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.
4 Installation 4.1 To do before the installation of the product 3 Attach the fan on to the roof curb with 4 screws. 4 Connect the primary electric supply to the connection box of the product. Refer to 12.3 Wiring diagrams. • Make sure that you have the necessary installation accessories: – Refer to 13 Accessory overview for an overview of the accessories.
3 Connect the primary electric supply to the connection box of the product. Refer to 12.3 Wiring diagrams. For the TFE fan, loosen the screws that hold the motor bracket to access the terminals that are attached to the motor bracket. 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.
5.5 Speed controller for EC motors 6 Commissioning Caution • EC motors are controlled through a stepless 0–10 V signal. • 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 use power supply for the speed controller. • Refer to 12.3 Wiring diagrams and the instruction manual for the external speed controller. 5.
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 AC motor 1 Set the installed safety switch in the ON position. 2 Install the external speed controller. Refer to the instruction manual for the installed speed controller. 7.
Maintenance task Usual operation conditions Each 6 months Each year Unusual operation conditions. 1 Each 3 months Each 6 months Visually examine the product and its components for damage, corrosion and dirt. X X Examine the fan impeller for damage and imbalance. X X Clean the product and the ventilation system. X Do a check of all fasteners and make sure that they are fully tightened. Make sure that the product and its components are correctly operated.
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.
