Fitting the hydraulic connection set
■
The pipes of the primary circuit/secondary circuit
connection set are located in the EPP box, which is
positioned on top of the appliance on delivery.
■
With the primary circuit/secondary circuit connection
set, the on-site hydraulic lines can be connected at
the
top
of the heat pump.
Note
The following connection versions are possible with
the hydraulic connection sets available as accessories:
■
Connection of the primary lines to the right or left
■
Connection of all hydraulic lines at the back
Note
We recommend fitting shut-off devices to the connec-
tion set on site. This will allow the primary and secon-
dary circuit to be shut off for maintenance work.
