Connection of refrigerant circuit
Don´t exceed maximum lenght of connecting pipeline. In other case preformance parameters can´t be fulfilled and the device
could be destroyed.

Pipeline have to be isonlated enough
Use only the insulation suitable for refrigerant circuits. The temperature of pipe surface can reach temperature of 120°C!
For outside environment use insulation at least 20 mm thick. For the inside environment suffices 10-15 mm.
Mentioned parameters apply for insulation with thermal resistance 0,045 W/(m.K) or better (at 20°C).
Crimping
At crimpring don´t use mineral oils on any parts. In other case you can reduce device life. In case of soldering fill the
pipeline with nitrogen gas for avoidance scales (minimum hardness 50% Ag). The gas must not be under pressure.
The crimping must be done with quality refrigeration tools. The pipeline must be cutted by cutting wheel. You will limit the creation
of the sawdust. Then you have to get rid of the edge of the pipeline which cutting wheel created. Then the crimping should be done according
to the parameters shown in this table.
