S320 and S320H Samplers, only - These samplers feature sample
refrigeration and need to dispose of a small volume of condensate
water. Samplers fitted with a Wastewater Drain are able to dispose
of Condensate Water. Samplers not fitted with a Wastewater
Drain, have a Condensate Water Drain. There are 3 alternative
methods of disposal of water discharging from the Condensate
Water Drain, which are as follows:
o
Construct a Gravity Drain from 21.5mm O/D plastic
pipe.
o
Deploy a Condensate Evaporator Tray (Part Number
CL-4112). (Note – This should have been specified
with the Sampler order as it cannot be retro-fitted).
o
(Outdoor Installations) Simply allow the condensate
water to soak away into the surrounding earth.
Pressurised Sampling Points
Samplers specified with the Pressurised Pipeline Interface (PPI) are
suitable for sampling from pressurised Sampling Points (typically
pipelines). Considerations when using a sampler to sample from a
pressurised Sampling Point are as follows:
•
The Sampler / PPI can be positioned above or below the Sampling
Point as required
•
The Intake Hose routing is non-critical.
•
Choose a Sampling Point where you can be sure that the
wastewater is well mixed and a representative sample will always
be available.
o
If there is likely to be any sediment at the bottom of
the pipe then it may be preferable to tap into the side
of the pipe.
o
If the pipeline is not always full then a tapping point
below minimum liquid level should be chosen.
•
Minimum Pipeline Tapping Point Pressure - The pressure in the
pipeline at the tapping point must always be sufficient to create
a flow of 0.5m/s in the Ø12mm bore Intake Hose. Consideration
should be given to the hydro-static head created by the relative
height of the Sampling Point with the Flush Discharge Level of the
PPI. See the PPI installation drawing, page 4.20 or page 4.22 for details.
A Sampling Point above the Flush Discharge Level of the PPI will
add to the pipeline pressure and a Sampling Point below the Flush
Discharge Level of the PPI will subtract from the pipeline pressure.
