Installation
Actuator with ‘First Open’ function
When delivered, the actuator is normally open in a de-energised state, thanks to the First Open function. This enables
heating mode to run even if the electric wiring is not yet completed.
When subsequently commissioned and with the application of power (for longer than 6 minutes), the First Open function
is automatically unlocked so that the actuator becomes fully operational.

Hydraulic connection
Note the following points when connecting the hydraulic side:
Install and test safety components (expansion vessels, pressure relief valves and overflow valves).
Route condensation lines with a sufficient cross-section without bends and narrow sections with a gradient to the in situ
waste water pipe.
Allow adequate space for the air flow (air inlet and outlet).
Observe the following additional points for cooling operation:
Install continuous, vapor diffusion-tight insulation on all water-bearing components (piping, valves, connections), in each
case up to the unit.
Select suitable pipe hangers (cold clamps) for cooling operation.
Sufficiently dimension the diameter of the condensate pipe.
Protect siphons (if any) in the condensate pipe from drying out.
When using the units without filters, ensure that the unit is operated at a maximum of 7.3 V, otherwise condensate may
drip. This will not happen with Kampmann filters installed.
When using filters not approved by the manufacturer, no guarantee regarding the performance specifications can be
given. In such a case, drops may also be ejected from the device.
