Mounting the sample connections
CAUTION!
Flooding of the surrounding area due to improper connection of the sample con-
nections.
Please note the following before opening the sample feed:
▪
The supply and return lines must be able to withstand the operating pressure.
▪
The medium pressure on the ScrubberGuard can be a maximum of 3 bar. If there is a
higher pressure in the supply line, a pressure reducing valve must be installed. The
pressure in the return line must not exceed 3 bar.
▪
All pipes must be fastened in place and secured so that no air can be drawn in. The
pipe connections should be checked about two weeks after commissioning to ensure
that there are no leaks.
▪
Drainage of the sample must be ensured at all times.
In order to ensure an accurate measurement, observe the following points when mounting
the sample connections:
▪
A continuous
water inflow of 4 .. 20 l/min
must be ensured.
▪
The maximum suction height of the optional sample inlet pump is 7 m. When dry, the
maximum suction height is 3 m.
▪
No mechanical forces should be exerted on the sample inlet and sample outlet, parti-
cularly vibrations. Flexible connecting pipes should thus be used.
