The MIND.MapsTM PLUS floor standing trolley ovens 20 GN 2/1 and 16FS and new 06 GN2/1 and 10 GN2/1 have
three rotor arms with a washing circuit as illustrated below. As the system has 3 valves and 3 rotor arms,
EG1 is shared with back fan guard cleaning and with G1 rotor arm. As the rotor arm has two nozzles to spray
detergent and water solution inside the cooking chamber; these nozzles implicate backpressure.
Therefore the line of the back fan guard cleaning has a flow restrictor on to equalize the pressure and avoid
all the water going to the fan nozzles.
