1.4. Installation Conditions and Operating Environment

1.4.1. Location requirements

The installation position of the fume hood should avoid facing the road and places where people pass frequently, avoid blocking windows and places with unfavorable ventilation and lighting, avoid blocking entrances and exits that affect the switch of the door, and avoid facing and placing them on corner walls.

1.4.2. Environment requirements

a) Only applicable to indoor operation

b) Ambient temperature: 15°C~35°C

c) Relative humidity: ≤75%

d) Atmospheric pressure range: 70 kPa~106 kPa

e) Power supply: the same as the rated voltage and rated frequency of the cabinet, see 2.1.4 technical parameters and performance indicators table;

f) The power supply needs to be reliably grounded; (judgment method: use a multimeter to test the live wire-to-ground voltage of the power supply, which should be the grid voltage, and the neutral wire to ground should be 0, otherwise the power supply grounding is not good).

1.5. Installation

1.5.1. Remove all the package materials

1.5.2. Check the surface of the base cabinet and the main body to make sure there is no scratch, deformation or foreign bodies

1.5.3. Carefully check the attachments and materials against the packing list in the instruction manual;

1.5.4. Move the entire equipment to a site that is as close as possible to the final location and is convenient for installation;

1.5.5. Check whether the ambient voltage frequency is consistent with the voltage frequency displayed on the label, and then power on.

Figure 5

1.5.6. Connect base cabinet with main body

Put the bottom cabinet in a suitable installation position, then put the fume hood cabinet on top of the bottom cabinet, adjust the upper cabinet to be flush with the back and both sides of the bottom cabinet, and fix it with bolts, and the fixing points are behind the two sides of the cabinet.

Figure 6

Put the pipe clip on the outer pipe first, then put the outer pipe on the air outlet of the cabinet, and fasten the pipe clip with a flat screwdriver; BFSD-404 has two air outlets, and the main pipe needs to reserve two air inlets for the installation of the exhaust pipe of the fume hood; BFSD-401, BFSD-402, and BFSD-403 all have one air outlet;

(4) Put on the countertop, install the sink on the countertop, and then connect the drain pipe of the sink in the bottom cabinet to the drain outside the cabinet;

2.4 Points that should be paid attention to during normal operation and normal operation and use process

2.3.1 Things to pay attention to during operation

Precautions

1. The fume hood is an important laboratory safety equipment. In order to ensure safe and normal use, please read this instruction manual and precautions carefully, and participate in appropriate laboratory safety and skill training;

2. Please read this manual before use.

3. Please keep this manual for future reference.

4. The company will not be responsible for any damage caused by improper use or self-changing product structure.

5. The equipment should not be placed near doors/windows or corridors where people flow frequently.

6. The power socket has good grounding.

7. Please turn off the power and unplug the plug when replacing the lighting lamp.

8. The packaged cabinet should be stored in a well-ventilated environment with no corrosive gas and no relative humidity of more than 75%.

9. The perspective window of the fume hood is made of explosion-proof tempered glass. In order to keep the window clean, it should be wiped with a damp soft cloth and kept away from hydrofluoric acid;

10. Lining accessories such as the deflector of the fume hood should be cleaned regularly according to the usage;

11. The air ducts and fans of the fume hood should be regularly cleaned and maintained by special personnel;

12. Do not place any equipment within 150mm from the glass window. Large-scale experimental equipment must have sufficient space and should not affect the flow of air.

13. During the use of the equipment, do not put soft and delicate items (such as soft paper towels) on the table, so as not to be sucked into the negative pressure air duct and fan by the suction port and affect the operation of the equipment;

14. The product shape and color of the company's pictures are subject to the actual product, and the product model is subject to change without prior notice.

15. The temperature of the contact plate in the operation area cannot be higher than 100°C.

Solemnly declare: The company will not be responsible for the risks caused by the operation not in accordance with the regulations!

2.3.2 Normal operation process

a. Turn on the power, the screen lights up and displays three horizontal bars .

c. Press the lighting button , the lighting indicator above the button will light up, press the lighting button again to turn off the lighting (you can choose to turn on or off the lighting according to the environment in the laboratory).

d. After use, turn off the fan and lighting, and place the glass door to the bottom.

e. If the power is cut off during use or the power plug falls off under abnormal circumstances, the device will maintain the last working state when the power is turned on again, that is, the working state before power-off when the power is turned on again , with power-down memory function.

2.4. Regular Maintenance

A detailed daily record of operating time is recommended, as the accumulated using time will directly affect the plan of maintenance.

Maintenance should be performed annually or every 1000 operating hours, and every restart.

NOTE: a) To avoid electric shock, please cut off ALL power before applying maintenance for the equipment!

b) The blower and the exhaust duct should be inspected and maintained regularly.

c) The accumulated operating time is a vital factor of deciding when the maintenance is needed. A comprehensive record of operation is highly recommended to be taken down after each time of operating.

Maintenance methods

a) Weekly and monthly maintenance

i. Clean the external surface and front window (refer to 2.4.1.)

ii. Check the various functions of the Fume Hood
