Mounting conditions
Route the suction line with a downward gradient to the sampling point.
Never mount the sampler in a place where it is exposed to aggressive gases.
Avoid siphoning effects in the suction line.
Do not route the suction line with an upward gradient to the sampling point.
Note the following when erecting the device:
• Erect the device on a level surface.
• Connect the device securely to the surface at the fastening points.
• Protect the device against additional heating (e.g. heaters or direct sunlight).
• Protect the device against mechanical vibrations.
• Protect the device against strong magnetic fields.
• Make sure air can circulate freely at the side panels of the cabinet. Do not mount the device
directly against a wall. Allow at least 150 mm (5.9 in.) from the wall to the left and right.

5.1.4 Connection for sample intake and for version with sample pump
• Maximum suction height:
• Vacuum pump: standard 6 m (20 ft)
• Peristaltic pump: standard 8 m (26 ft)
• Maximum hose length: 30 m (98 ft)
• Hose connection diameter
• Vacuum pump: 10 mm (3/8 in) or 13 mm (1/2 in)
• Peristaltic pump: 10 mm (3/8 in) internal diameter
• Intake speed:
> 0.6 m/s (> 1.9 ft/s) for 10 mm (3/8 in) ID, as per Ö 5893, US EPA
> 0.5 m/s (> 1.6 ft/s) for ≤ 13 mm (1/2") ID, in accordance with EN 25667, ISO 5667
Note the following when erecting the device:
• Always lay the suction line so that it slopes upwards from the sampling point to the
sampler.
• The sampler must be located above the sampling point.
• Avoid siphoning effects in the suction line.
Requirements for the sampling point:
• Do not connect the suction line to pressurized systems.
• Use the suction filter to impede coarse and abrasive solids and solids which can cause
clogging.
• Immerse the suction line in the direction of flow.
• Take the sample at a representative point (turbulent flow, not directly at the bottom of the
channel).
