Installation
3.1.
Installation Requirements
The Laminar Flow Enclosure is designed to be installed around an optical table.
Warning
Due to the weight and dimensions of the components, the following procedure must be performed by at least
two persons. Other persons may be necessary at certain points in the installation dependent upon the space
available. These points are identified by the following symbol next to the relevant text.
Caution
Before beginning the installation process, ensure that there is sufficient space in the area to install and
accommodate the enclosure. When assembled, the Laminar Flow Enclosure, measures 2.20 x 1.33 x 2.36
metres.
A clearance of at least 12" (~ 300 mm) should be maintained between the Fan Filter Unit and the ceiling. This is
essential to ensure optimal Fan Filter Unit performance.
Caution
Ensure that proper airflow is maintained to the Fan Filter Unit. Insufficient air flow will cause overheating and
premature failure.
3.2.
Environmental Conditions
Warning
Operation outside the following environmental limits may adversely affect operator safety.
Location
Indoor use only
Maximum altitude
2000 m
Temperature range
15°C to 40°C
Maximum Humidity
Less than 80% RH (non-condensing) at 31°C
Line Voltage Fluctuations Less than ±10% of the line voltage
To ensure reliable operation the unit should not be exposed to corrosive agents or excessive moisture, heat or dust.
If the unit has been stored at a low temperature or in an environment of high humidity, it must be allowed to reach ambient
conditions before being powered up.
The unit is not designed to be used in explosive environments.
Caution
Under certain conditions, the inside of the enclosure can become very hot and uncomfortable. To avoid this,
ensure that you do not:
Position the enclosure in direct sunlight
