t1 fume hood installation steps: determine the fume hood installation location, mounting brackets, installing fume hoods, installing exhaust ducts, connecting ducts and conducting tests.
1, determine the fume hood installation location: the fume hood should be placed in an accessible ventilation location, away from open flames, overheated equipment and contaminants such as smoke. It is recommended that the fume hood be installed in a spacious laboratory area and in front of the ventilation system.
2, mounting bracket: the bracket under the fume hood should be fixed and installed on a solid and smooth ground. The bracket is made of steel or concrete and supports the weight of the fume hood.
3.Installation of the fume hood: Place the fume hood on the bracket, connect the power cord and adjust the horizontal position of the fume hood.
4, install the exhaust pipe: connect the pipe of the exhaust port of the fume hood to the outdoor discharge port and make sure the connection is tight to ensure that the indoor polluted gases can be discharged smoothly after filtered by the fume hood.
5. Connecting pipes: connect the inlet water pipe and outlet pipe to the ventilator and make sure the connection is tight.
6, test: start the fume hood, check whether there is abnormal noise and odor, to ensure that the air flow is normal and meet the required standards. At the same time, test whether the fume hood meets the required safety and protection requirements.
Precautions for use:
Before each use of the fume hood, we should first check one side of the fume hood inside whether there is no cleanup items, if there is to be cleaned up in a timely manner, do not affect the day to do the experiment. Fume hood use process to regularly check the fume hood exhaust system, because the fume hood in the work, in a negative pressure state, and occasionally have to open the indoor window, make up for the fresh air, to avoid the laboratory has been in a negative pressure.
Laboratory to ensure that the normal temperature of the room, the summer must open the air conditioning, because some laboratories are closed state, only rely on fresh air, air conditioning wind to relieve the indoor air. Fume hood in the process of use, next to the staff must not leave, because most of the laboratory are operating chemicals, must not joke, is always to ensure safety.
The fume hood is opened, the fan sound is different from the usual, the noise is serious, at this time to immediately close the fume hood, please service personnel to check the circuit and fan problems.
