4.7 Modifying the screen cloth
The Airmix™ system requires modifications to the screen cloth, since a hole must be made in it so
that the Airmix™ can draw in air from above. This hole must be at least as large as the opening of the
Airmix™, and reinforced with triple stitching. The hole could be strengthen by stitching a stainless
steel axis at the long side of the hole. For more info please contact Van der Ende Group or your
screen supplier.
5. Connecting the thermostatic switch
A thermostatic switch is built in to the winding of every fan as standard. When connected, this switch
turns the engine off if voltage levels are exceeded and the internal temperature rises above 100 °C.
The motor gets too hot if the fan becomes blocked, or similar.
Connecting the fan as shown in Figures 4 and 5 increases its life span. The thermostatic switch is
connected in series with the phase. The red line in Figure 5 is the connection between TB and U1.
The FN035 thermostatic switch is NOT connected as standard in the factory, so this task must be
carried out by the installer.
PLEASE NOTE: This thermostatic switch has no hard reset, so when the engine has cooled
sufficiently it will restart. Therefore, always disconnect the plug from the power supply
during maintenance!
