1.6 Product liability 2 Safety Systemair is not liable for damages that the product causes in these conditions: 2.1 Safety definitions • The product is incorrectly installed, operated or maintained. Warnings, cautions and notes are used to point out specially important parts of the manual. • The product is repaired with parts that are not original spare parts from Systemair. Warning • The product is used together with accessories that are not original accessories from Systemair.
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. • Do not install or operate the product if it is defective. • Do not remove or disconnect safety devices.
4 Installation 4.1 To do before the installation of the product 1 Remove the 4 screws that attach the side panel to the frame and remove the side panel. The picture shows the MUB/T fan which has the locking system for the panel shown. The MUB fans, the MUB/T fans, the MUB ECO fans and MUB/F fans have no locking system or handle, only screws in the frame. • Make sure that you have the necessary installation accessories: – Refer to 13 Accessory overview page 33 for an overview of the accessories.
4 If necessary, install cable grommets. Refer to 4.2.3 To install cable grommets page 8. Note: 5 The MUB fan, the MUB CAV/VAV fan and the MUB/F fan can be installed in any angle on the floor, on the wall or in the ceiling. If the product is a MUB-CAV/VAV fan, set up the CAV controller. Refer to 4.2.5 To set up the controller for CAV/ VAV page 9. 6 If the product is installed outside, install weather protection.
4.2.5 To set up the controller for CAV/VAV To install the weather protection roof (WSD) 1 The fan is delivered with an EC motor and an air flow controller device which is factory set for maximum airflow in CAV (constant air volume control) mode. The CAV controller measures the air volume and adjusts the 0-10 V output signal for the EC motor to keep the air volume constant.
4.2.7 To connect the ducts to the product 5 Warning To install the product with circular duct systems, Systemair recommends to use CCM or CCMI flanged plate. The MUB/F fan switches off in case of fire. The MUB/F fan has no motor protection fitted as standard. Any kind of motor protection and frequency converter must be bypassed in case of fire. To install the product in rectangular duct systems, Systemair recommends to use the flexible connection FGV.
5.4 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.
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 year Unusual operation conditions.
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 13. 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.
