The drawings are provided solely as examples.
In particular, the unit is intended to be connected: to a hydronic system
that must be designed to be classied according to EN 378-1 as an indirect
ventilated system (ref EN 378-1; 2016, par. 5.5.2.2 ), as an indirect vented
closed system (ref EN 378-1;2016, par. 5.5.2.3 ), or as a double indirect sys-
tem according to EN 378-1 (ref. EN 378-1; 2016, par. 5.5.2.4 ).
■ Do not ll up the hydraulic system by glycol near the suction of the pump. High
concentration of glycol could stuck the pump. Do not use the pump to mix water
and glycol.
