Commissioning
The louvre dampers may need to be insulated on site against both sound
emission and the formation of condensate.
In the case of louvre dampers, follow the separately supplied installation
instructions for the damper servomotor.
Louvre damper drive shaft:
If louvre dampers are located on the pressure side, open them fully
before commissioning the fan.
Starting up the fan against closed louvre dampers can cause damage to the
unit.
Before commissioning, check the entire pipework system for leaks.
- Vent the heat exchanger and pipework system.
- With steam coils, secure the condensate drain to prevent damage to the
coil from steam hammers.
- Only start the heating water pump or open the water/steam valve when the
fan is running, to prevent overheating caused by insufficient heat transfer.
- Check the discharge temperature: Maximum discharge temperature 40 °C
if the heater is located on the intake side, otherwise there is a risk that the
motor will overheat.
- Protect heat exchangers against frost.
Be careful of hot surfaces of heat exchangers and connectors.
Risk of burns.
