Unpacking and Checking the Delivery

Unpack the equipment immediately after delivery, even if it is to be put into
operation at a later date.

Before doing so, examine the shipping container for any external damage.

Then completely remove the packaging materials. The shipping container and
packaging materials must be kept in the case of return shipments becoming
necessary.

Check that the equipment is complete and carefully examine it visually.

If any damage is discovered, report it immediately to the forwarding agent
and insurer. If the damaged part has to be replaced, please get in touch with
Oerlikon Leybold Vacuum.

In order to prevent the formation of condensate, leave the cold head to warm
up to room temperature before installing it.
