Mounting and start-up
− Observe the permissible ambient tem-
peratures(seesection3.1).
5.1.2 Mounting orientation
Standard
Preferably install the regulator in a horizon-
tal pipeline. The actuator housing with set
point adjuster must face upwards.

zontal pipelines
Î Install the control line to the tapping
pointwithanapprox.10%slopetoal-
lowanycondensingliquidtoowback
into the tank or pipe.
Options
Alternatively, the valve can be installed in a
vertical pipeline. The actuator housing with
set point adjuster must face sideways.

pipelines
Control deviations due to alternative instal-
lation.
System deviations may arise when the regu-
lator is installed in vertical pipelines.

5.1.3 Additional ttings
Strainers
We recommend installing a strainer (e.g.
SAMSONType2N)upstreamoftheregula-
tor. It prevents solid particles in the process
medium from damaging the valve.
Î Install the strainer upstream of the tem-
perature regulator. The arrow on the
valveindicatesthedirectionofow.
Î For installation in vertical pipeline: install
thestrainerwiththelterelementfacing
downwards.
Î Installthelterwithsufcientspaceavail-
abletoremovethelter.
Î Checkthestraineratregularintervals
and clean it, if necessary.
Shut-off valve
Install a hand-operated shut-off valve both
upstream of the strainer and downstream of
the regulator. This allows the plant to be shut
down for cleaning and maintenance, and
when the plant is not used for longer periods
of time.
Pressure gauges
Install a pressure gauge both upstream and
downstream of the regulator to monitor the
pressures prevailing in the plant.
