Filling The Plant; Insulation; Mounting Accessories - Samson EB 2111 Translation Of Original Instructions

5.6.3

Filling the plant

Open the shut-off valves slowly over a time
period of several minutes preferably starting
from the upstream pressure side to fill the
plant.
NOTICE
!
Risk of regulator damage due to steam
hammering.
Steam hammering is possible when the pro-
cess medium is a liquid with a boiling point
at atmospheric pressure.
Î Open the shut-off valves slowly prefera-
bly starting from the downstream side to
fill the plant over a time period of several
minutes.

5.7 Insulation

To insulate cold or heated systems, we rec-
ommend first filling the plant and carefully
rinsing it. The regulator must not yet be insu-
lated at this stage.
NOTICE
!
Risk of regulator damage due to incorrect
insulation.
Î Only insulate the regulator up to the con-
trol thermostat for medium temperatures
below 0 °C/32 °F or above
80 °C/175 °F.
1. Start up the plant and adjust the set point
(see the 'Start-up' section).
EB 2111/2121/2123 EN
2. Shut down the plant again.
Cooling applications: allow the regulator
to heat up until all the condensation wa-
ter has dried off.
Heating applications: allow the regulator
to cool down.
3. Insulate the regulator and pipes convey-
ing the process medium using insulation
material with a water vapor barrier. If a
capillary tube of the control thermostat is
to be routed through the insulation, spe-
cial care must be taken with the sealing
since slight changes in shape may occur.
The insulation thickness depends on the
medium temperature and the ambient
conditions. 50 mm is a typical thickness.

5.8 Mounting accessories

WARNING
!
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
Incorrect opening of pressure equipment or
mounting parts may lead to the process me-
dium escaping to the atmosphere.
Î Do not loosen the control thermostat
while the valve is pressurized.
Î Do not start up the regulator until all
parts have been mounted.
− The extension piece is installed between
valve and thermostat to protect the oper-
ating element against high temperatures.
