After 2 years, I am trying to get the Climma working again.  Both the saltwater and the circulation pump started up fine but I needed to fill up the circulation cycle a little bit to get to the required 1.5 bar.  The compressor starts up fine as well.  But while the temperature of the coolant decreases initially by a few degrees, it then stalls and increases again.  I suspect I have a coolant leak but I wonder whether there are alternatives to calling the service man to fill it up.  Any ideas?

Many thanks!
