2 Plug Fan CentriFlow 3D GMEC Installation and Maintenance Important Information, Safety notes, Technical Description 1. Important Information Fläkt Woods fans comply with the requirements for health and safety of the EC Machinery Directive. All fans leave the factory after being subjected to testing. These instructions are intended for use by professional service staff. The installation, commissioning and operation of the fans must be carried out by professional staff who are familiar with the safety regulations. Tools and protective equipment necessary for preventing accidents from occurring while installing and operating the fan must be used/worn in accordance with the local safety regulations. All personnel involved with the product must carefully study this operating manual and diligently comply with all orders and instructions. Fläkt Woods does not accept responsibility for any damage that can be attributed to non-observance of these instructions. The warranty issued by the manufacturer will be forfeited if any changes to the product are made without the manufacturer s consent. 2. Safety Notes This symbol is designed to point out all safety and danger related information regarding danger on the operating personnel s lives and health. 3.2 Operating conditions The standard operating temperature range of the fan is 20 C - +40 C. The maximum permissible ambient temperature of the motors is +40 C. The fans are designed to be used as parts of equipment. They are not ready for use as a stand-alone product and the standard version does not have protection against body contact, the appropriate protective measures are to be taken according to EN 292/294. Only operate the fan up to the maximum permissible speed given in the information on the fan rating plate. 3.3 Motors Centriflow 3D GMEC fans are supplied with high efficiency (IE4) permanent magnet external rotor EC-motors. The high efficiency is based on permanent magnets which eliminate rotor losses and therefore less magnetizing current is needed. Motors are equipped with integrated control electronics and speed can be controlled by using either 0-10 V control signal or input or the MODBUS-RTU interface for communication. The impeller is fastened directly to the motor. 3. Technical Description The fan is used to generate a desired air volume at a given pressure rise that corresponds to the pressure losses in the duct system to which the fan is connected, and internal losses inside of the Air Handling Unit. The plug fan is intended to be used inside of the Air Handling Unit. 3.1 Design 5 4 1 2 1. Front plate 2. Inlet cone 3. Impeller 4. Motor 5. Support bracket 3

Installation and Maintenance Plug Fan CentriFlow 3D GMEC 5 Mounting Instructions, Commissioning, Maintenance 5.4 Grounding Motor is grounded through the motor power supply cable. If extra grounding is needed, grounding can be done with a separate cable from the fan motor to the casing of the Air Handling Unit. The motor has a grounding marking next to the grounding point (View A). 7. Maintenance 7.1 Warranty A precondition of the warranty is that regular maintenance has been carried out. Defects under warranty must immediately be notified to the manufacturer or the importer. The warranty does not cover service work or indirect damages. A A 7.2 Maintenance 7.2.1 BEFORE MAINTENANCE Switch off the power supply to the fan at the safety switch and wait until the impeller is fully stopped. Extra grounding cable 7.2.2 Inspection The fan is to be inspected at least once a year. 5.5 Fitting the accessories The inlet protective screen can be fitted directly to the front plate of the fan or outside Air Handling Unit to the inlet opening. 5.6 Electrical connections All electrical connections must be wired by authorized personnel only. The necessary electrical and safety precautions must be taken into account. Connections must be done according to the instructions, see separate Controls Instructions for GMEC. 6. Commissioning 6.1 Safety checking - Check that the impeller rotates freely. Make sure that there are no foreign objects in the fan or in the Air Handling Unit. Also check that there is no unusual noise in the fan or motor. Check that the installation work has been carried out in accordance with the relevant regulations. Cables and air flow measurement tubes must be attached so that they do not touch the impeller All necessary protective devices must be installed. The fan may only be commissioned after all proper procedures have been followed and all necessary inspections have been carried out. 7.2.3 Checking the Motor Inspect that there are no visible damages on the fan or the motor. 7.2.4 Impeller The impeller can be cleaned by using a vacuum cleaner, compressed air or by brushing. If the impeller is coated with greasy dirt it can be washed with a detergent or a solvent. The cleaning is to be done at least once a year. Badly tarnished impeller will result in lower efficiency of the fan and increases energy consumption. The maximum permissible vibration levels are: Vibration level Alarm Shutdown BV-2 (below 3.7 kw) 14 15 BV-3 (over 3.7 kw) 11,8 12,5 Values are RMS-values in mm/s measured on the motor. 7.3 REPLACING THE fan Replace the fan unit in case of failure. The impeller and the motor cannot be changed. The fan has to be disconnected before removing. 6.2 Test run Briefly switch on the power supply to the motor to check whether the fan impeller rotates in the correct direction. If the impeller is rotating in the correct direction, the fan may be switched on. Check that no abnormal mechanical sound and no surging occur.

FAULTS If any faults occur during operation, they shall be repaired by qualified maintenance personnel. Some examples of incorrect use: - foreign particles inside fan (AHU) - corrosive media inside AHU - too low or high temperatures - too high vibrations - incorrect maintenance Possible problems generated: - bearing damage - corrosion damage - vibration generated damage - broken impeller 9. SPARE PARTS A complete fan is available as a spare part. No separate parts are available. For more information please contact Fläkt Woods sales unit. 11. Air flow measurement device The airflow sensor is used for measuring the airflow of the plug fans. The method is based on differential pressure. The pressure is measured at a specific point in the inlet cone and the reference pressure is measured upstream of the inlet cone. The air flow sensor is supplied factory mounted in the inlet cone. The air flow is calculated as a function of the coefficient k and the differential manometer reading Dp m from the equation: q v = 1 k q v = air flow m 3 /s k = k-factor of each fan Dp m = differential pressure reading (Pa) x p m 10. RECOMMENDED DISTANCE TO OTHER COMPONENTS To achieve the best possible operation of the fan inside of the Air Handling Unit the following minimum distances shall be followed: LD C R ØD E Size C Ø D E LD R 025 110 275 190 290 138 028 123 307 212 324 154 031 137 342 258 361 171 035 154 386 290 406 193 040 174 436 327 458 218 045 196 491 370 518 246 050 220 549 415 581 275 056 244 613 463 648 305 A x B GMEC-3-aaa k-factor 025 67.56 028 54.40 031 41.63 035 36.01 040 29.62 045 22.56 050 18.89 056 14.56 12.DISPOSAL OF THE PRODUCT Used product shall be disposed or recycled according to the local laws and regulations.
