Mounting the gas sampling hose
In order for the HYGROPHIL unit to be operated, it is vital that the gas sam-
pling hose is mounted precisely. You should therefore observe the following
instructions.
Before mounting the gas sampling hose, make sure that it is designed for
the same voltage as the unit. Please note that the gas sampling hose con-
sumes 100 W of power per meter. Without additional measures, the maxi-
mum length for the gas sampling hose is 12 m at 230 V and 6 m at 115 V!

Mounting instructions
No condensed water can be collected during normal operation of the unit if it
has been installed and programmed correctly. However, there is a risk of
condensed water being formed during operating breaks and in the case of ir-
regular operating states (compressed air or heating switched off).
You should therefore position the gas sampling hose in such a way that no
condensed water is able to gather in a sagging arc to form a 'water sack' that
blocks the flow of air.
Even when the compressed air is switched on again later, this alone will not
be enough to remove such a water sack, making manual intervention neces-
sary.
The hose should run either at a slant from the extraction point to the measur-
ing unit or upwards in the form of an arc.
Any condensed water that is formed should be able to flow either to the
measuring unit or to the extraction point. You must check whether con-
densed water is allowed to flow back to the extraction point.
If condensed water runs into the HYGROPHIL
in the measured values may result. This must be noted in the case of con-
nected closed-loop controls. The HYGROPHIL
not be damaged.
During mounting, make sure that the bending radius for the gas sampling
hose does not fall below the smallest permissible value of 160 mm.
Please also observe the following instructions with regard to positioning the
gas sampling hose.
Handling the gas sampling hose properly plays a key role in ensuring that it
remains fully intact for longer.
