Caution:

1. It is forbidden to wipe the lamp body with a wet cloth while cleaning in the powered state.
2. Prohibit the replacement in the powered state.

Caution

Storage Conditions
The Laminar Flow Cabinet should be stored in the warehouse with relative humidity not more than 75%, temperature less than 40℃, good ventilation, no acid, alkali and other corrosive gases. The storage cycle should not exceed one year. If it stored for more than one year, the open-package inspection is needed and only passed the inspection can it enter the circulation field.

Transportation Conditions
The cabinet should be transported in full accordance with the requirements shown on the outer surface of the packing area. The user should check the integrity of the packing area carefully when receiving the cabinet with packing area sent by the logistics company. If the packing area has damage, extrusion and other phenomena, please refuse to sign, and contact with our company in time.

Caution: Please contact with us in time when the cabinet that has been installed and used is relocated and moved again.

Caution

1. Before connecting the AC power supply, you need to ensure that the voltage of the power supply is consistent with input voltage and it is stable, and ensure that the rated load of the power socket is not less than the requirements. The Laminar Flow Cabinet adopts grounding plug, which has the third leg that could only match with grounding type power socket, so it is a safety cabinet. If the plug can not be inserted into the socket, you should ask an electrician to install a grounding type power socket. Be sure to confirm good grounding when using.
2. During the using process of the cabinet, do not put soft, fine items (for example: soft tissue paper) on the countertop, avoid sucking them into the negative pressure duct and fan by the inlet, which can affect the operation of the cabinet.
3. The maximum weight of items placed in the cabinet should not exceed 23kg/25×25cm2.
4. Avoid vibration: Avoid the use of vibrating equipments (such as centrifuges, vortex oscillators, etc.) in the cabinet, because vibration will make the particulate matter accumulated on the filter membrane shake off, resulting in the reduction of cleanliness inside the operating area. At the same time, if there is former operating surface balance failure, it will also cause Laminar Flow Cabinet contaminate to the operator.
5. Open flame is prohibited: The use of open flame is prohibited in the Laminar Flow Cabinet. The use of open flame will lead to flocculation of airflow in the operating area, and will damage the filter. During the process of experiments that requiring high temperature sterilization, it is highly recommended to use infrared sterilizer.
6. HEPA has service life. With the extension of the use period, dust and bacteria accumulation in the filter will lead to the increase of pressure loss of HEPA. When the increase of the velocity can not meet the requirements, you must promptly contact our service department to replace the HEPA, otherwise it will affect the safety of the cabinet. Replaced filter should be disposed according to the medical waste.
7. The fan and its lower side steel plate is the static pressure area cover, these air ducts are strictly sealed when leave factory and needed to maintain their tightness. The operator should not loosen or remove the screws of these parts. If there is a special need, it must be handled by our service personnel.
8. The storage period of the cabinet is one year. When it exceed the storage period, it must be opened and inspected once by the company’s technical personnel, only qualified can it be used.

Caution: Solemnly declare: If the cabinet is not used in accordance with the methods prescribed by our company, it may damage the protection provided by the cabinet, and our company should not be responsible for the risks caused by the operation that not in accordance with the provisions!
