1 Introduction 1.2 1.1 Product description The product is used for transportation of clean or contaminated air with a maximum temperature of 60 °C in continuous operation. The product is a roof fan with an EC motor and a safety switch. Intended use The product is intended for installation outdoors on commercial and residential buildings, with connection to a duct system. The TFC-S fan is supplied with a potentiometer for speed control. The fan size 355 to 560 can communicate via MODBUS.

2 Safety • Read this manual and make sure that you understand the instructions before you do work on the product. 2.1 Safety definitions • Obey local conditions and laws. Warnings, cautions and notes are used to point out specially important parts of the manual. • Keep this manual at the location of the product. Warning • Do not install or operate the product if it is defective. If you do not obey these instructions, there is a risk of death or injury.
3 Transportation and storage 4 Installation 4.1 To do before the installation of the product 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. • Before you move the product to the installation location, examine the packaging for damages. • Do not move the product by the cables, terminal box, fan impeller, protection grille, inlet cone or silencer.
1 Loosen the screws on the service lid to access the inner area of the casing. 3 To access the motor compartment, use the handle and lift the motor bracket until the motor bracket lock engages. The hinge is equipped with a click-in locking mechanism which holds the lid up when fully opened. Release the lock by pulling the lever beside the lock. Caution Keep fingers away from the back of the hinge. The back of the hinge is a potential pinch point. Note: TFC 225 and TFC 280 have no handle.
6 If a roof curb is used, obey these steps: A. D. Use the integrated cable hose to lead the main electric supply cable safely to the corner on the inner side of the roof curb. Attach the fan on to the roof curb by screwing it in place using supplied screws to the bottom of the fan casing. E. Note: Install the roof curb on the roof in accordance with applicable building standards and connect the fan to a duct system. Note: Do not fill the space at the bottom of the fan casing.
4 Press “Down” to go to “Metrics units” and press “P” to choose “1: metric unit” (The factory setting, measures in Pa, m3/h, K-factor). 4.2.4 5 Press “Down” to go to “Measuring range” and press “P” to set the measuring range: 1 Loosen the screws on the casing and the electrical cabinet and open the lids, refer to 4.2.1 To install the TFC-P fan and the TFC-S fan. 2 Remove the tube (1) from the minus inlet (-) and put it on the plus inlet (+) on the pressure controller.
9 Press “Down” to go to “Set the pressure set point” and set the pressure setpoint: • Setpoint 1 — The normal operation pressure setpoint. • Setpoint 2 — The pressure setpoint during a secondary operation mode. The factory setting is 50 % of the measuring range. Setpoint 2 is active when there is a connection between input 1 and 2. The active setpoint is shown in “Info” with a moon symbol when setpoint 2 is active.
5 Electrical connection 5.1 To do before the electrical connection 6 Commissioning Caution • Make sure that the environment for electrical connection is clean and dry. • 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. • Make sure that the wiring diagram that is included with the supply of the product agrees with the terminals in the connection box.
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.
Maintenance task Usual operation conditions Each 6 months Make sure that the product and its components are correctly operated. Each year Unusual operation conditions. 1 Each 3 months X Each 6 months Each year X Measure the power consumption and compare the result with the information on the name plate. X If vibration dampers are installed, make sure that they operate correctly and examine them for damage and corrosion.
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. The fan impeller does not turn in the correct direction. Make sure that the electrical connection is correctly done.
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.
