Installation
5.6 Insulation
To insulate cold systems, we recommend first
filling the plant and carefully rinsing it. The
regulator must not yet be insulated at this
stage.
1. Start up the plant and adjust the set point
(see the 'Start-up' section).
2. Shut down the plant again and let it heat
up until the condensation water has
dried off.
3. Insulate the regulator and pipes convey-
ing the process medium using insulation
material with a water vapor barrier. If a
control line is to be routed through the
insulation, special care must be taken
with the sealing since slight changes in
shape may occur. The insulation thick-
ness depends on the medium tempera-
ture and the ambient conditions. 50 mm
is a typical thickness.
NOTICE
!
Risk of regulator damage due to incorrect
insulation.
Î Only insulate the regulator up to the ac-
tuator for medium temperatures below
0 °C or above 220 °C.
