Ordering service work
The procedure is simple:
1. print the service order and fill in the relevant fields.
2. send us your regulator(s), computer, jacket, wing, dryi... with the completed service order.
3. once we have received your shipment, we will review your order and send you an order confirmation by email. Now we need your approval - also you can already instruct the payment.
4. as soon as we have received your approval, we will carry out the work.
5. test passed and payment received? Already the good piece goes back to you...
