New household appliance: warranty and installation

[Frantic 72]

Hi,

 

today we will probably order the new kitchen. It will be without household appliance for two main reasons:

 

1. I don't want to pay the big surcharge usually the Kitchen seller put on the price of household appliances.

2. I want to choose the house hold appliances. In this case they told me I would receive the kitchen next spring 

 

The day the kitchen will be mounted by who is selling me it, I will also have a separate person that will take care to install/connect the appliances.

I have doubt about the warranty. Does this person have to have any title in order to be recognized as a proper technician ? Or in the future the appliances vendor will refuse the warranty because it was not installed by a proper "professionist" ?

This person will come is registered as freiberufler and will release regular invoice.

 

The kitchen seller doesn't want to take care of the anschluss of the the appliances because doesn't want to become resposnbile for the warranty.
