1.3 Installation Conditions and Operating Environment

Laminar flow cabinet shall be placed in a protection area, workspace can not be right opposite to the door or window, and away from the outlet of air conditioning, prevent from the ventilation system, air conditioning, door, window, and personnel movement caused by the airflow impact on Laminar flow cabinet.
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 for indoor operation
(2) Ambient temperature: 15° C ～35° C
(3) Relative Humidity: ≤75%
(4) Atmospheric pressure range: 70KPa～106KPa
(5) Electrical parameters: Adequate power supply to the laminar flow cabinet(See 2.1.4 Technical 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 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 packing 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 assembled base stand refer to Figure 4

Figure 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.
Please connect main body and base stand refer to Figure 5

Figure 5
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 figure 6 and 7.

Figure 6


Figure 7
h. After the above steps, move cabinet to the right cabinet position slightly, remove the power cord, check the power cord is intact. See figure 7.

2.3 Instructions for 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 of 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 (e.g. centrifuge, vortex oscillator, etc.) inside the cabinet. The contamination might drop from the HEPA filter thus making the operation area cleanliness lower.
(5） No flame: An open flame would create turbulence which disrupts the pattern of HEPA-filtered air supplied to the work surface. 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 within the HEPA filter, filter resistance is getting bigger, when it reaches the maximum point, the speed requirements can’t be met then please contact BIOLAB service department to get a new one. The used filter should be processed as medical waste.
(7） Please do NOT remove or loose the screws of those parts. To contact service personnel for special technical requirements.
(8） The maximum storage period is one year. If the period is more than one year, performance test should be done
Serious declaration: we 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 relevant function keys (related keys, function and operation please refer to 2.2.2 description); check the function keys and the operation results are consistent, and according to the above technical parameters table to test whether the blower normal starts and wind speed is up to the standard requirements, fluorescent lamp and UV lamp is normal work.
UV lamp function could only be selected when front window is fully closed.
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.
