WARNING!
Make sure that no cleaning residues remain and that the components, especially the valves, are completely dry after
drying process before assembly. Ingress of water can cause icing inside the device if not carefully dried.
Failure to follow this warning can result in serious personal injury or death.
Higher temperatures and longer duration than recommended may cause the plastic and rubber materials to
age more quickly, shortening the service life of the equipment.
