Danger
Leaks in the refrigerant lines can cause refriger-
ant to collect in the KG conduit. Some refriger-
ants, e.g. R32, form flammable mixtures with air.
Fire can cause serious damage to health.
When working on the KG conduit, ensure that
the refrigerant lines are tight.
Note
We recommend letting condensate drain away freely,
without a condensate pipe.
