be mounted on the left/right, expansion/primary flow DHW storage tank
connection of the boiler. The pump is being supplied with electric current
from the boiler, see ”Electrical installation.
Drainage/Drain valve
Shall be mounted on the drainage connection on the front side of the boiler.
Filling
Filling is performed via the heating system filling valve. Alternatively filling can
