Regarding the Safety of Using Negative Pressure Weighing booth

Negative pressure weighing hood is also a common local purification equipment in laboratories, and its use can protect the external environment and the safety of indoor personnel. Of course, we must follow the following safety rules when using it.
1. The negative pressure weighing hood is for indoor use, please do not use it outdoors.
2. Please choose a floor or wall structure that can withstand the weight of the equipment, and the installation location should have a flat surface.
3. It is not allowed to install in a tilted state, otherwise it may cause deformation of the box and other faults.
4. Prohibited from use in harsh environments such as low temperature, high temperature, high humidity, condensation, dust, oil mist, chemical corrosion, etc.
5. This equipment is not explosion-proof and is prohibited from being used in flammable and explosive environments.
6. When designing the equipment, fully consider the customer's production requirements to ensure that the equipment can operate 24 hours a day, but cannot be used continuously at full load.
7. Do not clean with water to avoid damaging the electrical components of the equipment or causing personal injury. The equipment itself can be regularly cleaned with alcohol and stainless steel cleaner.
8. The equipment must be fixed in place first, and then personnel must carry out wiring and power on.
Before starting up, please confirm whether the rated voltage and frequency of the equipment are consistent with the parameters of the input power supply to avoid damaging electrical components and even causing fires.
10. Reliable grounding operation must be carried out on the equipment to ensure safe use.
11. Be sure to connect the required power cord correctly and reliably to the power junction box, and pay attention to the power phase.
12. It is strictly prohibited for users to modify the electrical circuits of the equipment without authorization.
13. Please do not place heavy objects on the power cord and do not pinch the power cord to avoid fire and electric shock caused by damage to the power cord. In case of shutdown, please cut off the power supply.
14. It is strictly prohibited to repeatedly operate various switches within one minute to avoid damaging the control device due to frequent actions.
When using a touch LCD screen, the movement should be gentle to avoid damaging the touch LCD screen.
16. It is strictly prohibited to place items near the air inlet of the equipment to avoid affecting the air intake.
When abnormal situations occur during the use of the equipment, the operation should be stopped first, the power should be cut off, and then personnel should be notified for maintenance.
When replacing the lamp tube, please cut off the power first and wait for it to cool down before replacing the lamp tube.
19. The maintenance channel and return air channel are designed as a whole. The operator can replace the filter and perform maintenance on the fan through this channel (it must be confirmed that the fan is not working), and the high-efficiency filter can be replaced in the clean area.
The replacement and maintenance of the negative pressure weighing hood sensor and touch LCD screen must be operated by personnel.
