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). An external potentiometer can be connected if necessary. If so
the internal potentiometer needs to be disconnected from the connection terminals. It is also possible to use an exter-
nal pressure meter to set the desired airflow using the K-factor table (chapter 4.3).
The P-fans are regulated with a built in differential pressure and airflow controller. The fans are delivered with VAV con-
trol – Variable Air Volume but can be converted to CAV – Constant Air Volume (see chapter 4.2).
This manual consists of basic information and recommendations concerning the design, installation, start-up and opera-
tion, to ensure a proper fail-free operation of the unit. The key to proper and safe operating of the unit is to read this
manual thoroughly, use the unit according to given guidelines and follow all safety requirements.
The TFC 225-560 S/P are intended for transportation of air in air handling systems. The fans are meant for use in ducted
systems and should always be duct connected on the inlet side. No moving parts shall be accessible after installation.
TFC 225-560 S/P roof fans are adapted to continuous operation.
Roof fans are exclusively intended for extract air applications.
Danger
• The fans are not to be used in hazardous environments or connected to flue ducts.
• The appliance must be connected to a mains circuit breaker in the fixed installation.
• Switch power off (all-pole circuit breaker) before servicing or maintenance, and make sure the impeller
has come to standstill.
• Make sure protection grid has been installed (EN ISO 13857), no moving parts shall be accessible after
installation.
• Do not remove, short-circuit or disconnect safety accessories (i.e. motor protection, safety grille).
Warning
• The fans can have sharp edges and corners which may cause injuries. Be careful when opening the fans,
the motor assembled on the motor bracket is relatively heavy.
Caution
• Take precautions to prevent the back flow of exhaust gases from flues from other appliances installed in
the same room, which are fired by gas or other fuels.
• This appliance can be used by children aged from 8 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision
or instruction concerning use of the appliance in a safe way and understand the hazards involved.
Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children
without supervision.

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, char-
acteristic K)
3.3 Transportation and storage
All fans are packaged at the factory to withstand normal transport handling. When handling the goods use suitable lift-
ing equipment in order to avoid damage to fans and personnel. Avoid blows and shock loads. Store the fans in a dry
place protected from weather and dirt until final installation.
Warning
• The unit is heavy. Be careful during transport and installation. Risk of injury through pinching. Use
protective clothing.
• Do not lift the fans by the connecting cable, connection box, motor bracket, impeller or inlet cone.
4 Installation
Danger
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Warning
• The units electrical connection to the mains supply must be preceded by an all pole circuit breaker with a
minimum 3 mm gap.
• Do not lift the fans by the connecting cable, connection box, motor bracket, impeller or inlet cone.
• Do not block or cover the drainage gap around the bottom of the fan.
The fan should be installed horizontally. Make sure the assembly of the fan is firmly fixed and stable. The fans must be
installed to ensure that service and maintenance can be performed easily and safely. Disturbing noise can be reduced
by installing silencers (available as an accessory). Electrical connections are made according to the wiring diagram in
the terminal box, markings on terminal blocks or on cable. All 3 phase fans are delivered from factory in 400 V 3~
connection.

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 con-
troller, the tubing from the bottom of the fan (1) to + (plus) inlet and the tubing from the cone (2) to - (minus).
The tubing from the cone is labelled with blue tape.
In BASE SETUP 5.01 in table 1, set the K-factor (see chapter 4.3). In SETTINGS, adjust the airflow for Setpoint 1, Setpoint
2 and Pband (nominal airflow x 2 recommended).
4.3 K-factor
Use the following equation to calculate the requested setting:
k ·
q = p
q = airflow [m3/h]
k = k-factor
p= tuning pressure [Pa]

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.
Testing the installation:
• Adjustment may be required in the electrical compartment during test (i.e. changing of the potentiometer), however
during operation the lid must be closed.
When putting into operation, check the following:
• Connection data corresponds to the specifications on the nameplate: Maximum voltage +6%, -10%, according to IEC
38. Rated current must not be exceeded with more than 5% at rated voltage.
• The direction of rotation should correspond to direction-of-rotation arrow (3 phase).
• Smoothness of motor operation, (no abnormal noises).
Sound levels exceeding 70 dB(A) may occur depending on size (see www.systemair.com for detailed information).
4.5 Alarm output
The fan motor has built in protection for locked rotor, which implies that the motor tries to restart with a pre-pro-
grammed interval whenever it senses that the rotor is standing still. When the blockage is removed the fan will start up
by itself without any further measures. At high motor temperatures the current will be cut from the motor. It can then
only be restarted by manually disconnecting the mains supply to the fan for couple of minutes.
TFC 225 and TFC 280 has Tacho output
The tacho output is an open collector output. Connect a pull up resistor to a DC voltage – make sure that the current
does not exceed 10mA.
