· Before soldering the valve into the pipework, the flow direction
must be carefully checked
· Make sure that all soldering material, copper grindings etc. are
removed from the pipework
· The valve body must be cooled with a wet cloth during the solder-
ing
· Mount a filter upstream to the valve
· The pipework must be fixed so that the valve connection supports
do not come under any mechanical load. Vibrations can lead to
pipework breaking!
· Evaporator temperature below 0 °C:
the valve body (incl.top/signal converter)and pipework leading
away from the valve must be isolated
· Evaporator temperature above 0 °C:
only the valve body and the pipes leading away from the valve
must be isolated (see picture).
Do not isolate upper part and electronics (overheating)!
Pressure sensor
· Pressure sensor must be mounted upright over the pipework
· Can be mounted directly on the suction pipe
Temperature sensor
·
135°
·
·
The further the sensor is from the evaporator, the more stable the
control (max. 2 m).
It is recommended to increase the setpoint of superheat accordingly.
