Establishing the connections
• Use hoses that are suitable for a pressure of at least 1 bar.
• Shorten the stepped hose adapters according to the hose diameter in use.
• Secure the hose with a hose clip.
• Hand-tighten the union nut of the stepped hose adapter.
• Screw the stepped hose adapter with the flat seal or O-ring onto the connection so that the
connection is leak-tight.
• You can choose from the two connections arranged opposite each other to ensure that the
hose is routed optimally.
– Use the closing cap to close the connection that is not in use.
– Vitronic 55 W: The closing cap has an inspection glass for function checks.
