1.4 Installation Conditions and Operating Environment

1.4.1 Location requirements

To avoid disturbances to the Fume Hood and its operator, please follow the guideline below, while determining a suitable location for the equipment

a) Fume Hood should not be installed in positions where they are likely to be affected by other items or equipment. Windows, doorways, fans, room air supply diffuser or ventilation outlet should be away from the Fume Hood.

b) The distance from the front window to any circulation space or air-handling equipment should be at least 1000 mm, so as to preserve a zone undisturbed by anyone other than the operator

c) The position of a Fume Hood should satisfy the spatial requirements (e.g. vision, lighting and convenience of access) of the operator and personnel working nearby.

d) When a Fume Hood is installed on a bench top, the leading edge should be flush with or slightly overhanging the edge of the bench top.

1.4.2 Environment requirements

a) Only applicable to indoor operation

b) Ambient temperature: 15°C~35°C

c) Relative humidity: ≤75%

d) Atmospheric pressure range: 70 kPa~106 kPa

1.4.3 Electrical requirements

a) Electrical parameters: consistent with the rated voltage of the Fume Hood (See 2.1.4 Technical parameters and 2.1.5 Performance index)

b) Power supply need to be grounded (Judging method: test the live wire and the neutral wire of the main 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.)

c) Test the voltage stability before using. If the voltage is unstable, use a voltage regulator to adjust. Otherwise, the control panel and transformer may be easily damaged

2. User Instructions

2.1 Functions

2.1.1 Product concept

This product belongs to Fume Hood. Fume Hood is a kind of negative pressure ventilation system for protecting operator and laboratory environment. Room air flows inward from the front opening of the Fume Hood and is consistently ventilated by the extract blower. Therefore, contaminated fumes, vapors, toxic gasses, aerosol and corrosive substance which are probably generated during experiments could be prevented from spreading to the operator or into the laboratory room. In addition, the polluted air could be purified by the active carbon filter (optional) before exhausting through the duct. Thus, the outdoor environment could also be protected.

NOTE: Experiments with the use of flammable, explosive substances and strong acids or bases should NOT be conducted by this Fume Hood.

2.1.2 Operating principle/air flow pattern

Figure 12

2.1.3 Protected object

The primary goal of the Fume Hood is to protect operators and laboratory environment from exposure to infectious aerosol and toxic fumes which may be generated from the reaction during experiments.

2.1.4 Technical parameters

Table 4

NOTE: a) Power supply consumption includes the consumption loaded at working zone, which should not exceed 500W.

b) Biobase reserves the right to make changes in future product design, without reservation and without notification to its users.

2.1.5. Performance index

a) Vibration amplitude

The net vibration amplitude, at a range of frequency from 10 Hz to 10 KHz, would not exceed 5 μm (rms)

b) Illumination
