Dockings
General
NIBE SPLIT ACVM 270 can be connected in several different
ways, some of which are shown on the following pages.
For more detailed docking descriptions, see www.nibe.eu.

* 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.
