11 GLEC-6 - Installation and maintenance Reattach the outlet connection. 5.2 OUTDOOR INSTALLATION If the fan is installed outdoors, all seams of outer side of the fan casing must be carefully sealed with fireproof sealing compound and rain cover (available as an accessory, see technical catalogue) for motor and speed controller must also be installed, see picture below. Rain cover 7. Reattach both hatches and remove support stands. Speed controller must be moved do fit under rain cover with motor, if needed. UV-shield for speed controller plastic parts (included in rain cover delivery). 5.3 FITTING THE ACCESSORIES Connections to duct system must always be done with flexible connections (available as an accessory, see technical cataloque). Providing necessary grounding for the accessories is within the constructor s field of responsibility. 5.4 SAFETY REGULATIONS The fan is equipped with speed controller, care should be taken that the speed controller is always in upright position, even if the outlet direction is changed. The fan must be always equipped with safety switch. If the fan is delivered without optional safety switch, the switch must be provided otherwise. Residual risk due to inappropriate behavior or malfunction during operation cannot be completely excluded. The system planner or constructor must prevent the emergence of any hazardous situations through suitable safety measures. Note that the impeller may rotate due the air flow in duct system, even if the fan is isolated from mains. Motor terminals may still be Live if the impeller is rotating, even when the main incoming supplied has been isolated. Ensure the impeller is kept stationary before opening and whilst the terminal box is open.

12 12 GLEC-6 - Installation and maintenance 5.5 ELECTRICAL CONNECTIONS All electrical connections must be wired by authorised personnel only. The necessary electrical and safety precautions must be taken into account. The fan must always be equipped with safety switch. Electrical connections shall be done as shown in drawing. Motor cable shall be shielded type. Shield should be grounded 360 at both ends of the cable. If the VSD will be mounted separate from the fan, the motor cable should be no longer than 5 meters. Basic circuit arrangements (not the delivery entities) below: GLEC AND GLEC GLEC

13 GLEC-6 - Installation and maintenance 13 6 COMMISSIONING 7 MAINTENANCE 6.1 SAFETY CHECKING Make sure, that the fan is isolated from mains. Open the cleaning hatch (see 3.1 Design, part 9) and rotate the shaft to check that the impeller can move freely. Make sure that there are no foreign objects in the fan or in the ducting. Also check that there is no unusual noise in the fan. Check that the installation work has been carried out in accordance with the relevant regulations. All necessary protective devices must be installed. Check, that all other regulations related to fire safety are followed. The fan may only be commissioned after all proper procedures have been followed and all necessary inspections have been carried out. 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 shown with the arrow, the fan may be switched on. Check that no abnormal mechanical sound and no surging occur. 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. 7.2 MAINTENANCE BEFORE MAINTENANCE Switch off the power supply to the fan from the safety isolating switch. Wait for the impeller to stop completely. Note that the impeller may rotate due the air flow in duct system, even if the fan is isolated from mains. Motor terminals may still be Live if the impeller is rotating, even when the main incoming supplied has been isolated. Ensure the impeller is kept stationary before opening and whilst the terminal box is open INSPECTION INTERVALS Inspection intervals can be defined by local authorities. If nothing else is mentioned, the fan shall be tested according to the intervals in table, but at least once a year. The annual inspection must be done by authorized personnel only. In order to assure safe operation we recommend to do the checking at regular intervals by specialized personnel or company and to document the results. FAN Pos.

14 14 GLEC-6 - Installation and maintenance CHECKING THE MOTOR BEARINGS If the fan is used as a dual purpose fan, the motor bearings shall be checked twice a year. After hours it is recommended to change the motor. It is recommended to change the motor every three years CLEANING THE IMPELLER The maximum permissible vibration level measured from the motor bearing is 7,1 mm/s RMS. The impeller can be cleaned 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 done if necessary, but a control inspection should be done at least once a year. Badly tarnished impeller will result in lower efficiency of the fan and increases energy consumption. 7.3 FINAL INSPECTION Check that: - The overlap between the impeller and the inlet cone is same as before maintenance. - The inlet cone is aligned precisely with the impeller. - All screws and nuts have been tightened. - Glass fiber sealing is in good condition. - No foreign objects have been left in the fan or in the ducting. 7.4 FAULTS If any faults occur during inspection which cannot be repaired by maintenance personnel, please contact the service department at Fläkt Woods. Examples of faults can include the following issues: - foreign particles inside fan - corrosive media inside - too high vibrations - incorrect maintenance Possible problems generated: - bearing damage - corrosion damage - vibration generated damage CLEANING THE FAN CASING The inside of fan the casing can be cleaned same way as the impeller.

16 16 GLEC-6 - Installation and maintenance 10 AIR FLOW MEASUREMENT (OPTIONAL) The airflow sensor is used for measuring the airflow of the fan. The method is based on pressure differential. The pressure is measured at the specific point in the inlet cone and the reference pressure is measured upstream of the inlet cone. The air flow sensor is factory mounted in the inlet cone. 11 CODE KEY Kitchen exhaust fan Type (a) 6 = High temperature Size (bbb) 031, 040, 050 GLEC-a-bbb-c-ddd-0 Motor (c) 1 = 1-phase motor (sizes 031 and 040) 3 = 3-phase motor (size 050) Motor power (ddd) 055 = 0.55 kw (GLEC-6-031) 080 = 0.75 kw (GLEC-6-040) 220 = 2.20 kw (GLEC-6-050) Version (e) 0 The air flow is calculated from the equation: q v = A Dp m k q v = air flow (m 3 /s) k = k-factor (see name plate of each fan) Dp m = differential pressure reading (Pa)
