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℃~35℃
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
