Default connection of the transformer is 600V (E). Depending
on the configuration of the fan motor and the local power
supply, you must change the connection.
• If applicable: change the connection of the transformer (E).

Depending on the connection voltage of the fan, you must set
the thermal relay inside the control box to the correct value.
• Determine the thermal relay setting that belongs to your
specific configuration in the table below.
• Adjust the thermal relay to the correct setting with a
Phillips-head screwdriver.

4.9.2 Pressure setting
Applies to all types of units
The differential pressure switch inside the control panel
activates the filter cleaning system as soon as the pressure
drop reaches the threshold value. This guarantees the
optimum performance of the unit. The pressure setting
depends on the specific configuration and motor frequency.
• Determine the required threshold value (pressure in mbar)
from the table below.

As the manufacturer does not know in which configuration the
WallPro Basic is installed, you must use these pressure setting values
as a guideline only. The optimum pressure setting will be a matter of
experience. The lower the pressure setting, the sooner the filter
cleaning system is activated.
In case of early activation: increase the pressure setting.
In case of late activation: decrease the pressure setting.
Recommended step size to increase/decrease is 3 mbar.
• Demount the transparent cover of the differential pressure
switch.
• Set the required pressure according to the table.
• Install the cover.
• Close and lock the control box.
