7.6 Hydraulic installation
Hydraulic installation of units with supplementary heater with hot water (optional)
■ 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 balance the pipework for the the individual units within a control
zone to ensure even distribution.
Attention
Danger of damaging the units. Do not fasten any loads to the coil,
e.g. by means of the flow or return lines.
Hydraulic installation of units with hydraulic assembly for diverting system (option)
■ Connect the heating coil to the on-site hydraulic network using the hydraulic
assembly:
– Install the assembly horizontally.
– Mount the assembly so that its weight does not need to be absorbed by the
coil.
– Insulate the assembly.
■ Read off the default settings for the hydraulic alignment from Fig. 27. The
curves 1.0 to 4.0 correspond to the revolutions of the valve spindles of the
balancing valve; they are shown on the turning knob:
0.0 .......Valve closed
4.0 .......Valve completely open
■ The coil and the hydraulic assembly are already included in the specified pres-
sure drops. Thus, only consider the pressure drops of the distributor circuit up
to the screw connections.

Return temperature sensor (option)
■ Install the return temperature sensor on the return line, directly after the screw
connection.
■ Attach the sensor with the clamping band.
■ Insulate the sensor.
