5.4 Hydraulic installation
■
Connect the heating coil according to the hydraulic circuit diagram.

Depending on local conditions, check whether compensators for linear expan-
sion are required for the supply and return lines and/or articulated connections
are required for the units.
■
Insulate the hydraulic lines.
■
Hydraulically aligned the individual units with one another within the control
group to ensure uniform pressure admission.
Attention
Danger of damaging the units. Do not fasten any loads to the coil, e.g. by
means of the flow or return lines.
