1.3 Installation Conditions and Operating Environment
Laminar Flow Cabinet shall be placed in the protective area of an air stream, and the working area of
the Laminar Flow Cabinet can not be near to the door or window, and should be away from the air
outlet to prevent the air flow from the ventilation system, air conditioning, door, window and
personnel.
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:
a. Only applicable for indoor operation;
b. Ambient temperature: 15° C ～35° C
c. Relative Humidity: ≤75%;
d. Atmospheric pressure range: 70KPa～106KPa;
e. Electrical parameters: Adequate power supply to the laminar flow cabinet(See 2.1.4 Technical
Parameters);
f. 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 the surface of main body to make sure there is no scratch, deformation or foreign bodies;
c. Confirm the complement of accessories according to the list.
d. Before removing the packing material, move the entire equipment to the place where it is going to
be installed.
The base stand will be packed at back of main body, please take it out before installation.
DO NOT INVERT, DISASSEMBLE OR TILT THE CABINET during transportation.
e. Assemble the base stand with main body as shown in the picture.

Please connect the base stand with the main body referring to Picture 4
Picture 4
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.
If you have any questions please contact engineers for commissioning
f. connecting main body and base stand.

First, keep the main body above the base stand. (picture 5), then align the bolt of base stand.
Mounting holes of the Main body at both sides, using Hexagon head bolt M10*55, flat washer 10,
Spring washer 10 insert through base stand and the side panel and make them stable.
g. Pick up the gas (water) tap from accessory kit, first, unscrew the tap and nut, find the Mounting
holes at the both side of cabinet glass. The Tap needs to be fixed as shown in the picture. The water
mouth of the Tap should be inside the cabinet’s operating zone, refer Picture 6, The other end of the
Tap which is having threading on the pipe should be inserted through the glass hole, the threaded
pipe should be fastened with washer and nut outside the glass and need to be tightened with a wrench.
Please refer the below picture to carry out the tap fixing to the cabinet. See picture 6 and 7.

2. User Instructions
2.1 Functions
2.1.1 Product Concept
Laminar Flow Cabinet – is used 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.
It is widely divided into vertical and horizontal laminar airflow type.
This series is for horizontal type.
2.1.2 Operating Principle/Air flow Pattern
Picture 8
2.1.3 Protected Objects
Laminar flow cabinet is to protect the experimental material, to create a local high cleanliness air
environment, the main role is to ensure the accuracy of the operating area of the experiment, but for
the environment and operators can’t afford protection.

2.3 Instructions of Operation
2.3.1 Normal Operation Notice
（1）Make sure input voltage is correct and stable. The rated load of main power socket should be
higher than cabinet consumption. Plug must be well grounded.
（2）Moving principles of different samples inside cabinet: When two or more samples need to be
moved, be sure that low-polluting samples move to high-polluting samples. Movement of
items should also follow the principles moving slowly and stably.
（3）The weight of items placed in the cabinet should not be more than 23Kg/25×25cm2；
（4）Avoid vibration: avoid using vibration equipment (eg centrifuges, vortex oscillator, etc.)
Water

inside the cabinet. Vibration would cause lower cleanliness of operating area and affect
operator protection.
（5）No flame: No flame is allowed inside the cabinet. Using of fire will lead to airflow disorder,
and filter damage. If sterilization is required during the experiment, infrared sterilizer is
highly recommended.
（6）HEPA filter life: With the usage time increasing, dust and bacteria accumulate inside HEPA
filter. Filter Resistance is getting bigger, when it reaches the maximum point, the speed
requirements can’t be met. Then need contact BIOBASE service department to get a new one.
The used filter should be processed as medical waste.
（7）The steel plate is under fan, which is sealed strictly in the factory. The operator is not allowed
to remove or loose screws of those parts. If necessary, please contact service personal.
（8）The maximum storage period is one year. If the period is more than one year, performance
test should be done .
Serious declaration: BIOBASE will take no responsibility for risks caused by improper
operation and man-made damages!
2.3.2 Operation Process
a. Connect to a suitable power supply
b. Press the relevant key functions (related keys, function and operation of the 2.2.2 in the
description); check the function keys and the operation results are consistent, and according to the
above clean table technical parameters of the test whether the normal start and wind speed is up to
the standard requirements, lighting and ultraviolet lamp is normal work.
c. The cabinet should be sterilized by UV lamp for at least 30 minutes with the window fully closed
before any experiment.
(1) For safety of eyes and skin, people should leave the room during the UV sterilization.
(2) UV lamp should be checked regularly. It should be replaced when either the total working
time reaches 600 hours or the intensity is lower than the requirement.
d. Please move up the front window at the suitable height above the work table and turn on the fan.
Make sure the experiment should be started after fan working for at least 30 minutes..
For operating safety, please place the experiment materials inside the cabinet before
experiment start.
After finishing the experiment, please fully close the front window and make sure to sterilize the
cabinet by UV lamp for 30 minutes before turning off the cabinet.
