1) Notice the combination between coolant inlet temperature and real environmental temperature:
the coolant inlet temperature should be max. 5°C under the real environmental temperature (otherwise danger of
condensation exists)!
2) at coolant water
3) for deviating discharge values notice the discharge diagram (see chapter 16.5)
