Terms and Conditions

This Agreement was last modified on 18 February 2021.


The following terms and conditions shall apply for the installation, installation instruction, commissioning and servicing work to be performed by us and for all ancillary work involved in the above. Any agreements that contradict these terms and conditions shall only be binding for us if they have been expressly acknowledged in writing. This shall also apply for agreements with our representatives (for example commercial agents or service agents) or for statements issued by our representatives. Our current general terms of business shall apply in addition to these terms and conditions for installation, commissioning and servicing work.


  1. The work shall be performed as agreed and as set out in the order confirmation on the basis of the actual number of hours worked (Work charged by the hour), at a fixed price to be paid separately (Work charged at a fixed price) or with the full or part inclusion of the price for work in the price for our service (Work charged at set rates ).
  2. The agreed rates of remuneration have been calculated on the basis of the tariff rates in force at the time when the order was placed and therefore form the basis for our calculation. In the event of these tariffs changing after the placement of the order we shall be entitled to make an appropriate adjustment to our charges. The prices set out in the order confirmation and in the installation, commissioning and servicing order are net prices.
