1 Introduction 1.1 Product description in outdoor environments with weather protection. The product is applicable for ambient temperatures of between -25 ° C and +70 °C. K fans, KV fans and prio fans are made for installation in circular duct systems. This product is a circular duct fan with an airtight casing made from sheet metal. The product is not supplied with a safety switch, external speed control, or FK fast clamps, these parts are available and recommended as accessories.

2 Use the fast clamps (A) to attach the duct to the product. Systemair recommends to use FK fast clamps to attach the duct to the product. The FK fast clamps are available as an accessory. 5 Electrical connection 5.1 To do before the electrical connection Refer to13 Accessory overview page 30 . • 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.
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 10. 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.
