1.3 Installation Conditions and Operating Environment
Laminar flow cabinet should be placed in a position where the airflow can be protected.
Laminar flow cabinet should not be installed opposite to door or window and far away from the air
outlet of air conditioner. It should avoid airflow influence from ventilating system, air conditioner,
door, window and movement of people.
At least 300mm gap must be kept in the side and back side of the Laminar Air Flow for clean
operating and for inspection.
Working environment:
(1) Only applicable to indoor operation;
(2) Ambient temperature: 15℃～35℃;
(3) Relative Humidity: ≤75%;
(4) Atmospheric pressure range: 70 kPa～106 kPa;
(5) Electrical parameters: Adequate power supply to the Laminar flow cabinet (See 2.1.4 Technical

9
Parameters );
(6) Power supply need to be grounded; (Judging method: test the live wire and the neutral wire of the
socket with multimeter. The voltage between live and ground should equal to the voltage of local
electrical grid, and the voltage between neutral and ground should equal to 0. Otherwise the
power supply is not grounded correctly);
1.4 Installation
a. Remove all the packing materials;
b. Check for Physical damage or scratch the surface of main body during transit. Make sure there
is no damage, scratch, deformation or foreign bodies;
c. Carefully check the accessories and material according to packing list in the manual.
d. Before breaking the package, move the entire equipment to the place where it is going to be
installed.
NOTE: Direct installation is completed for base stand part at the time of transport or it is
put at the back of the laminar flow cabinet. Base stand should be taken out before installing:
When carrying the laminar flow cabinet, top-for-bottom, dumping place and dismantling are
forbidden.

10
e. Assemble the base stand (if have) referring to Picture 5.
BBS-DDC/BBS-SDC base stand
BBS-DSC/BBS-SSC base stand
Picture 5
Removing Hexagon cylinder head bolt on both side lateral brace and T frame, the bottom of T frame,
assemble referring to the picture, fasten the screw and Cap nut on the both side of base stand.
Foot height can be adjusted. Clockwise rotation of feet, when feet height is less than casters, the
cabinet can be (or base stand) moved; anticlockwise rotation of feet, when feet height is greater than
casters, then play a fixed role in preventing the cabinet (or base stand) from moving.
NOTE: If there are any questions, please contact the Engineer for process debugging
f. Connect base stand with main body
Please connect the base stand with the main body referring to Picture 6.

2. User Instructions
2.1 Functions
2.1.1 Product Concept
Laminar Flow Cabinet –LAF Cabinet is only for sample protection.
Laminar Flow Cabinet is a work bench or similar enclosure, which creates a particle-free working
environment by taking air through a filtration system and exhausting it across a work surface in a
laminar or unidirectional air stream. The laminar flow cabinet is enclosed on the sides and kept under
constant positive pressure in order to prevent the infiltration of contaminated room air. This model is
vertical laminar flow cabinet.
