1.4 Installation Conditions and Operating nvironment
Installation position of fume hood should be avoided to face road and sites people frequently
go through, avoided to clog windows and places where ventilation and lighting are not good,
avoided to block the entrance and exit and place where the open or close of the door is
affected ,and avoided to place oppositely or in the corner of the wall.
Working environment
(1) Only applicable for indoor operation
(2) Ambient temperature 15° C ～35° C
(3) Relative Humidity ≤75%;
(4) Atmospheric pressure range 70 kPa ～106 kPa;
(5) Electrical parameters Adequate power supply to the fume hood (See 2.1.4 Technical
Parameters);
(6) The power should be grounded (Use a multimeter to test the voltage of the live line to
ground and the voltage of the null line to ground respectively, among which, the voltage of
the live line to ground should be the grid power, and the voltage of the null line to ground
should be 0, otherwise, the power is not grounded well).
1.5 Installation
a) Remove all packaging components

b) Check whether the outer surface of the host has scratches, deformations or foreign
objects;
c) Check carefully the accessories and information by referring to the packing list in the
operating manual;
d) Move the entire equipment to a site which is as close as possible to the position where
the equipment is placed finally and convenient for installation;
e) Check if the environment voltage frequency is the same with the voltage frequency
shown in the label;
Method to connect the upper cabinet and the lower cabinet
(1) Place the lower cabinet in the proper installation position, brake the caster brakes, then
place the upper cabinet on the lower cabinet, and let the left, right, rear side of the upper
cabinet align with those of the lower cabinet;
(2) Fix the upper and lower cabinets to prevent skidding and open the front acrylic door on
the upper cabinet, and then take the accessories out including stainless steel hexagon socket
head cap bolts M10 * 20 and stainless steel large flat washer 5, and fasten well the lower
cabinet and the upper cabinet, as is shown in Figure 7

（3 ） Take the activated carbon filter from the paper package, and put it in the filter locating
slot on the filter mounting panel, and then place the fan assembly above the activated carbon
filter located in the bottom, and finally place the second activated carbon filter above the fan
assembly.
（4 ） Connect the butt plug on the fan assembly with the butt plug on the operating panel,
and fasten them well; connect the butt plug of the fluorescent lamp with the butt plug on the
operating panel, and fasten them well; connect the butt plug of the VOC sensor with the butt
plug on the operating panel, and fasten them well; plug the air velocity sensor plug on the
corresponding position of the operating panel; plug the humidity sensor plug on the
corresponding position of the operating panel.
1.6 Inspection after Installation
After the equipment is powered on, check the following items according to 2.3.2
Checking Items Normal Working Status
Equipment power status Connect the ambient power, the equipment
can be powered on
Fan running situation
Press the fan button, the fan runs normally,
press the fan air velocity button, the speed
can be adjusted
Fluorescent lamp Press the fluorescent lamp button, the lamp
can be lighted up.
If you have any questions, please contact our agent to debug. Debugging method
is in the After-sale service manual.

02 User Instructions
2.1 Functions
2.1.1 Product Concept
In chemical laboratories, a lot of odors, moisture and corrosive substances will be generated
during the experiment. To protect the safety of users and prevent the spread of pollutants in
laboratories, fume hoods are used.
Note: Filters of BFSD 500 series non-ducted fume hood have poor adsorption effect to
hydrogen, helium and inert gases, methane, ethane, ethylene oxide, carbon monoxide,
carbon dioxide, nitrogen monoxide, propylene, propyne, acetylene, organophosphorus
compounds Mercury, hydrogen cyanide, radioisotope. Generally speaking, the
adsorption effect to gas with a molecular weight of less than 36 is not good, in such
case, it is not recommended to use such a fume hood. In addition, in experiments with
large amounts of volatile chemicals, experiments with large amounts of smoke,
experiments with strong acid and alkali, experiments with flammable,explosive, toxic,
such kind of fume hood cannot be used.

2.1.3 Protected Objects
Safety is the biggest mission pursued by fume hoods. The use of fume hoods in laboratories is
to ensure the safety of users and to prevent contamination of the laboratory environment.
