Caution If you do not obey these instructions, there is a risk of damage to the product, other materials or the adjacent area. • Approved hearing protection • Approved protective gloves • Approved protective shoes • Approved work clothing Note: Information that is necessary in a given situation. 2.2 Safety instructions Warning Read the warning instructions that follow before you do work on the product.
3 Transportation and storage 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. 4 Installation 4.1 To do before the installation of the product • Make sure that you have the necessary installation accessories: – Refer to 13 Accessory overview page 23 for an overview of the accessories. • Before you move the product to the installation location, examine the packaging for damages.
4.2 1 To install the product Install the product on the mounting feet. Make sure that the weight of the product is equal on the mounting feet. Make sure the drain plug is at the lowest point of the product to drain the condensation. 4.2.1 1 Systemair recommends to use flexible connections or FK fast clamps to attach the duct to the product. Flexible connections and FK fast clamps are available as accessories. Risk of damage to the product if there is much water that cannot drain.
5 Electrical connection 5.6 5.1 To do before the electrical connection • If the product has an built in motor protection, reset by disconnecting the product from power for 60 seconds. • Make sure that the electrical connection agrees with the product specification on the motor name plate. • Make sure that the environment for electrical connection is clean and dry. • Make sure that the wiring diagram that is included with the supply of the product agrees with the terminals in the connection box.
6 Commissioning 7 Operation Caution Caution • 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. 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.
8 Maintenance Warning Set the installed safety switch in the OFF position before you do the maintenance unless the instructions tell you differently. Make sure that the safety switch is not accidentally set in the ON position. 8.1 Maintenance schedule The intervals are calculated from continuous operation of the product. Maintenance task Usual operation conditions Each 6 months Each 3 months Each 6 months Visually examine the product and its components for damage, corrosion and dirt.
9 Troubleshooting Note: If you cannot find a solution to your problem in this section, speak to Systemair technical support. 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 8. The fan impeller has damages or deformations because the transported air contains aggressive media. Speak to Systemair technical support.
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.
