Warnings, cautions and notes are used to point out specially important parts of the manual.
• 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. • Make sure that you can read all warning signs and labels on the product when it is installed.
4 Installation 4.1 To do before the installation of the product 4.3 Note: Systemair recommends to use flexible connections to attach the duct to the product. Flexible connections are available as accessories. • Make sure that you have the necessary installation accessories: – Refer to 13 Accessory overview page 20 for an overview of the accessories. To connect the ducts to CE fans 1 Use the fast clamps to attach the duct to the product.
1 Install the flexible connection USE on the outlet. Use guide rails to attach the flexible connections to the duct. Guide rails are not supplied by Systemair. Flexible connection USE is available as an accessory. 3 If you install the product near a duct bend, do these steps to prevent vibrations, unwanted noise and decreased air pressure: a. Measure the distance (A) between the product and the duct bend. b. Make sure that the distance (A) is a minimum of 2.5 x the diameter (B) of the duct system.
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 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. 7.2 To stop the product 1 Set the installed speed controller in the OFF position. Refer to the instruction manual for the installed speed controller. 2 Set the installed safety switch in the OFF position. 7.2.
Maintenance task Usual operation conditions Each 6 months Examine all cable connections for damage. Make sure that the cable glands are tight against the cables. If flexible connections are installed, examine them for damage. 1. Each year Unusual operation conditions.
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 page 9. 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. 12 10.1 To disassemble and discard the parts of the product 1 Disconnect and disassemble the product in the opposite sequence of electrical connection and installation.
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. • The instructions in the data sheets are obeyed. • Maintenance instructions are obeyed. • A product that is not operated continuously is operated for a minimum of 1 hour each month. 12 Technical data 12.1 Technical data overview Max.
