Installation guidelines
N O T I C E
Before a cleaning or disinfecting cycle is started, stop the vacuum pump and put
a cover on the air inlet fitting.
N O T I C E
High internal temperatures cause damage to the instrument components.
• Install the instrument indoors in a clean, dry, well ventilated,
temperature controlled location with minimum vibration.
• If the room is washed down at regular intervals, install the instrument
outside of the room. Only the air inlet and vacuum tubes will go into
the clean room. As an alternative, put the instrument in the clean room
in a sealed box. Connect all tubes and cables to the instrument
through the box. Operation of the instrument in an enclosed box may
increase the temperature around the instrument and decrease the
performance and life of the instrument.
• Do not operate the instrument in direct sunlight or next to a heat
source.
• Install the instrument as close to the sample source as possible. Make
sure that the distance is not more than 3 m (10 ft). An inlet tube length
longer than 3 m (10 ft) can cause a loss of particles larger than 1 μm.
If an inlet tube length longer than 3 m (10 ft) is necessary, compare
the results between a portable particle counter and this instrument.
• Keep the air flow in a constant downward direction. When possible,
mount the instrument directly below the sample point.

Vacuum system guidelines

• Put the vacuum pump in a central location. There must be sufficient
vacuum for all instruments in the network.
• Use a distribution manifold that keeps vacuum loss to a minimum.
Typical materials used for vacuum distribution include brazed copper
pipe, schedule 80 PVC pipe or tubing such as Cobolite
