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
