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 external 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 control – 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 operation, 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.
