For the installer, before installing the wall mounted extractor fan, it is necessary to determine a mounting orientation. Confirmation of this orientation needs to pay attention to the use environment, and it is most suitable to see which part is installed in order to achieve the best effect. When installing, it is highly recommended to pay attention to whether each fastener is tightly installed, and ensure that the exhaust fan can operate normally and safely.
Special attention should be paid to ensure steady installation, the exhaust fan should be placed in a stable horizontal position, and the exhaust fan needs to be installed in an easy-to-operate orientation for daily use.
Generally speaking, when installing an exhaust fan, a bracket is required, and certain skills and precautions are indispensable.
Before installing wall mounted extractor fan, these things need to be checked such as whether the fan is intact, whether the fastener bolts are loose or fall off, whether the impeller has a collision hood and whether the fan blade or louver is damaged during transportation. When installing and selecting the air outlet environment, it should be noted that there should not be too many obstacles within 2.5 -3m opposite the air outlet.
When installing the fan, first of all, it is required to stably adjust the fan to a horizontal position to the foundation so that the motor should not be tilted after installation. Secondly, adjust the bolt of the motor in a convenient position so that the adjustment of the belt tightness will come in handy. Then it is also necessary to make sure again that the bracket is level with the foundation, and if necessary, install the angle iron next to the fan for reinforcement. Lastly, after the fan is installed, check the surrounding sealability. If there is a gap, it can be sealed with a sun plate or glass glue.
When the installation is completed, it is of great importance to check whether there are any leftover tools and debris inside the fan. Use the hand or lever to move the fan blade to check if it is too tight or rubbing, and if there is no abnormality in the items that hinder the rotation a test run can be conducted. If there is vibration or abnormal noise or another abnormal phenomenon of the motor during operation, it should be stopped for inspection, and then restart the wall mounted extractor fan after being repaired.
When the wall mounted extractor fan is used for a long time or after a long time, some motor failures will occur, which greatly affects the use of the extractor fan. Therefore, exhaust fan maintenance personnel must pay attention to the following points: First, it can be operated only under the condition that the fan equipment is completely normal. Second, if the fan equipment is started after the inspection, it is necessary to pay attention to whether the parts of the fan are normal. Third, regularly remove dust, dirt, water and other impurities inside the fan and gas transmission pipeline and prevent rusting. Last but not least, note that the repair of the fan equipment is not allowed during operation.
