Flameproof pressure-rotating axial local fan, its installation and commissioning of: 1. Before using the ventilator, first read the instructions carefully Nanchang fans offer, shall be installed in accordance with the relevant requirements. 2. Within 10 meters fan can not have debris, so as not to affect the normal operation of the fan and the air intake. 3. Before starting to check whether the fan has been tightened fasteners, loose, connecting member is firmly connected and the fastening bolts should be galvanized to prevent rust. 4. The gap between the fan impeller and housing, should be uniform, not less than 1 mm, rotation of the impeller should be no obstruction phenomenon, and the direction of rotation to be consistent with the direction indicated. 5. Fan a prolonged period, should be used again when the first measurement of the insulation resistance, in order to meet the requirements after the power is turned on, or to be processed until the compliance date. When the fan test run 30min, if all goes well then we can officially start using. 6. The motor current size should be based on respect, fans and other conditions, to use the correct power cable to prevent problems. 7. Cable, contact should be good after wiring and reliable connection, but also to meet the electrical requirements. Junction box, the box should be no dust to securing the junction box cover inspection no problem. 8. The fan should have a good grounding, the operation should not have abnormal Nanchang fans, if anomalies should immediately stop processing.
