IMPORTANT NOTE!
•Vent all other connecting lines on site.
• Top up the water level if necessary.
• Repeat this work depending on the type and
design of the hydraulic network on site.
• Open all (on-site) shut-off devices and valves.
• Hold a receptacle in place to catch any water that escapes and
protect the environment from spraying water.
• Then open the vent screw(s).
• Close the vent screw when no more air and only water escapes.
• Switch on the mains voltage.
• Start up the Venkon fan coil unit using the control unit connected.
• Check the fan speeds by switching the stage selector.
• Check the correct operation of the heating or cooling valves by
altering the room temperature setpoint Take into account the
different response times depending on the controller.
• Add water to the condensate tray - the pump should automatically
switch on and off again.
• Test the condensate alarm: Add water until the external device
(warning alert, shut-down mechanism) is triggered.
