Mechanical Installation - Hach MET ONE 6000P Manuel D'utilisation

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 tube 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.
• Keep the power cable plug visible and easily accessible.
• Make sure that the power receptacle is no more than 3 m (10 ft) from
the instrument.

Mechanical installation

Install the sample probe
Refer to Sample probe guidelines
prevent contamination of the instrument and to get a representative
sample of the area. The position of the sample (isokinetic) probe is
important for count accuracy.
Sample probe options
Optional kits are available for sample probe installation. Refer to
Figure 5.
• Direct mount—No kit is necessary. The sample probe is installed on
a short piece of tubing directly on top of the sample air inlet fitting on
8 English
on page 8 before the installation to
the instrument. Use direct mount installation when the instrument can
be put in the location where the sample is collected. Use the direct
mount installation to keep particle loss to a minimum.
• T-type wall bracket—The sample probe is installed in a wall bracket.
The tubing is cut to connect the probe to the counter.
• Vertical wall mount—The sample probe is connected to a stainless
steel tube and bracket. Use vertical wall mount installation on
equipment with stainless steel tubing.

Do not use this instrument to monitor air that contains vapors from drying
adhesives or other chemicals. These vapors can permanently coat the sensor
optics or other internal parts.
