Servicing-Information

Every Steel system is individually pro-
duced and therefore has a unique
customer order number which is
located in three places:
• On the mounting plate
• On the information for the elec-
trical installer
• In the information folder for the
end customer
Please state this customer order
number in connection with all
enquiries, service callouts and spare
part orders.
We have saved all the important
characteristics of your Steel system
under this number. This will facilitate
the troubleshooting process and
ensure that you receive the correct
spare parts.
