Product information | 3 Product information 3.1 General This installation manual concerns Roof fans TFC 225, TFC 280, TFC 355, TFC 450, TFC 500 and TFC 560 manufactured by Systemair Sverige AB. The S-fans are delivered with potentiometer, 0-10 V. The integrated potentiometer is factory preset to 10 V. This value can be changed manually to obtain a different motor rpm/fan performance. Fan performance charts for this purpose are shown in the table by voltage steps (chapter 3.2.2).

10 | Installation 3.2.4 Residual current devices Only universal (type B, B+) RCD protective devices are permitted. Like frequency inverters, RCD protective devices cannot provide personal safety while operating the device, pulse charge currents from the capacitors in the integrated EMC filter lead to the RCD protective device triggering without delay. We recommend residual current devices with a trigger threshold of 300mA and delay triggering. (super-resistant, characteristic K) 3.
Installation | 4.1 Installing the fans Figure 1 Loosen the screws to open the lid to reach the motor. Unscrew the two screws to open the lid to the electrical compartment. Figure 2 Connect the mains supply to the lockable safety switch (1). Image show S-controller (2). The hinges on the hatch to the electrical compartment prevents the hatch from falling down. Figure 3 Possible to mount the TFC with suitable roof curb (optional), using the holes in the bottom of the fan (3).
12 | Installation 5 4 Figure 5 Mains supply (4) can be run through the cable glands beside the electrical compartment or inside a roof curb, if used. Note: Don’t cover this gap (5). It is for drainage if water enters the fan.
Installation | 4.2 Change from VAV to CAV TFC 225 -TFC 560 are delivered as VAV- fans. The tubing is connected to - (minus) inlet on the controller. All fans are also prepared with tubing for CAV (Constant air volume). The tubing is attached along the side of the casing and loosely inserted in the electrical compartment. Change the function to CAV by replacing the connection to the controller, the tubing from the bottom of the fan (1) to + (plus) inlet and the tubing from the cone (2) to - (minus).
14 | Installation 4.4 Commissioning Danger • All electrical connections must be carried out by an authorized installer and in accordance with local rules and regulations. Before initial operation, check the following: • Electrical connection has been properly completed. • Protective earth has been connected. • Safety devices in place (protection grid). • Leftover installation materials and foreign materials have been removed from the casing.

18 | Maintenance 6 Maintenance 6.1 Important Danger • Make sure that the mains supply to the unit is disconnected before performing any maintenance or electrical work! • Fan impeller has come to a complete standstill. • Should the supply cable be damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard • The unit is heavy. Be careful during transport and installation. Risk of injury through pinching. Use protective clothing.
Troubleshooting | Loosen the M5 screws to open the lid (chapter 4.1.) Unscrew the motor bracket's two screws. Lift the motor up by holding the motor bracket's handle, keep fingers away from the back of the hinge. Make sure that the motor bracket attach to the lock to prevent the motor from falling down during maintenance. After maintenance, release the lock, using the handle to bring the motor down. Fasten the motor bracket with the screws.
