Question about Bosch Hausgeräte WTH83V03

According to the manufacturer's instructions, appliances from different manufacturers with different dimensions should not be installed in a washer-dryer column. A Bosch connection kit WTZ20410, a connection kit with pull-out worktop WTZ11400 or a universally suitable intermediate installation frame is required to securely and stably attach the appliances. Please note, however, that the appliances must have a width of 60 cm. I have linked the corresponding connection sets below:
