Operation and Commissioning
Switching on
NOTE!
Check the unit for contamination
(residual packaging, dirt, etc.), remove
this if necessary. Then vent the heat exchanger.
NOTE!
On-site connecting lines also need to be
vented.
The water volume may need to be
fi
lled up.
The work may need to be repeated depending
on the type and design of the hydraulic system
on
site.
7.2 Venting the Heat Exchanger
Open all shut-off devices and valves (on site).
Keep a collecting vessel ready for escaping water
and protect the surroundings from escaping spray water.
Then open the vent screw(s).
Close the vent screw when no air and only water is still
escaping.
7.3 Switching on the Unit
Switch on the mains power supply. Put the unit into operation
using the connected control unit.
Check the fan stages by changing over the stage selector.
Check the operation of the heating or cooling valves by
changing the room temperature setpoint. A varying response
time needs to be taken into consideration depending on the
controller.
Put water in the condensate bucket - the pump must
switch on and off automatically.
Testing the condensation alarm: Add water until the externally
connected device (warning message, cut-off device) is triggered.
Loud air intake noises may occur when air is drawn
in for the
fi
rst time!
