2 Safety • Read this manual and make sure that you understand the instructions before you do work on the product. 2.1 Safety definitions • Obey local conditions and laws. Warnings, cautions and notes are used to point out specially important parts of the manual. • Keep this manual at the location of the product. Warning • Do not install or operate the product if it is defective. If you do not obey these instructions, there is a risk of death or injury.
3 Transportation and storage 4 Installation 4.1 To do before the installation of the product 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. • Make sure that you have the necessary installation accessories: – Refer to 13 Accessory overview page 31 for an overview of the accessories. • Before you move the product to the installation location, examine the packaging for damages.
2 Open or remove the lid. 4.2.2 To attach the connection box Note: This procedure applies to products where the connection box is supplied loose inside the product. 1 Attach the connection box to the outlet side of the fan casing with the 4 supplied screws. Note: The arrow on the name plate shows the direction of the airflow. 4.2.1 1 To open the product Loosen the screws on the lid that is connected to the fan.
4.2.3 To install the KVK Silent fan and the KVK Slim fan 1 Attach the mounting bracket to the fan casing with the 4 supplied screws. 2 Attach the product to the floor, wall or the ceiling with 4 screws or 4 pendulum bars and screws. 4.2.4 1 Attach the product to the floor, the wall or the ceiling with screws. 4.2.5 1 To install the KVK DUO fan and the KVK fan To install the KV DUO 150 EC fan Fold out the 4 flaps from the fan casing.
2 Attach the product to the floor, the wall or the ceiling with 4 washers and 4 screws. 4.2.7 1 4.2.6 1 To install the KV DUO 400 – 630 EC fan Attach the product to the floor, the wall or the ceiling with screws through the outer mounting rails. To install the KV DUO 250 – 315 EC fan Attach the product to the floor, the wall or the ceiling with 4 screws through the 4 press nuts in the bottom of the fan casing. 4.2.
4 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. For circular ducts, (B) is the nominal diameter. For rectangular ducts, (B) is the hydraulic diameter. A 5 Electrical connection 5.
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 12. 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.
