• 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
soldering
• 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.
CPS40
Mount as near as possible to the
evaporator outlet (max. distance 2 m /
6.5 ft) on a straight piece of pipework /
inmediately after or on the outside part
of an elbow
Fix with a cable tie
Isolate
