5. Switch on the unit using the controller. Check whether the
unit blows out air.
Models with water heating and/or cooling
Check if the heat exchanger is connected correctly:
1. Make sure the CH and/or CW system is (are) switched on.
2. Let the unit heat and/or cool using the controller.
3. Feel whether the discharged air flow is getting hot (if
heating) or cold (if cooling). This may take a little while.
4. Vent the heat exchanger, if necessary.
Models with cooling and condensate discharge pump
Check the working of the condensate discharge pump:
1. Pour water into the condensate drain tray. The conden-
sate pump should start working shortly.
Models with ventilation
1. Check the seal of the fresh air duct: it should be draught-
free.
For models with ventilation and recirculation
2. Let the unit ventilate and recirculate using the controller.
Check whether the air valve moves to the right positions.
3. Check whether the air valve closes correctly in both open
and closed position.
If the valve does not close correctly, the unit may not be
level or properly supported. Correct this.
4. Switch the power off, and check if the valve opening closes
automatically.
5. Switch the power on again, and recheck the valve for nor-
mal operation.
