3 Note: Information that is necessary in a given situation. Transportation and storage Warning 2.2 Safety instructions Warning Read the warning instructions that follow before you do work on the product. • 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.
4 Installation 4.1 To do before the installation of the product 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 always put at the lowest point of the product to drain the condensation. • Make sure that you have the necessary installation accessories: Caution – Refer to 13 Accessory overview page 17 for an overview of the accessories.
4.2.1 1 To connect the ducts to the product Put the ducts on the duct connections of the product. Note: 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. 5 Electrical connection 5.1 To do before the electrical connection • Make sure that the electrical connection agrees with the product specification on the motor name plate.
5.6 To install motor protection for AC motors 6 Commissioning Caution • If the product has an built in motor protection, reset by disconnecting the product from power for 60 seconds. • 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.
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 Each 3 months Each 6 months Visually examine the product and its components for damage, corrosion and dirt. X X Examine the fan impeller for damage and imbalance. X X Clean the product and the ventilation system. X Do a check of all fasteners and make sure that they are fully tightened. Make sure that the product and its components are correctly operated.
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. 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.
