General
SPLIT can be connected in several different ways, some of
which are shown on the following pages.

* Regards circulating volume.
External circulation pump must be used when the pressure drop in the system is greater than the available external pressure.
In such cases, a bypass line with non-return valve must be installed.
Overflow valve must be used if min. system flow cannot be guaranteed.
