Spillage test and pressure differential switch
The test should be carried out to ensure that the fan speed and the pressure differential switch (PDS) have
been correctly set for the appliance. This should be made with all the doors and windows closed. If any
extractor fans have been fitted, the test should be made with these fans on. If spillage is detected, the fan
speed must be turned up.
Please refer to the appropriate Exodraft fan control installation guides, for further commissioning
assistance.
