Maintenance
The digital manifold requires maintenance work when used regularly:
•
Clean the screen and the housing surface with a cloth
and cleaning agent.
•
Do not use corrosive cleaning agents or solvents to clean
the unit. Weak household cleaners and soap suds may be
used.
•
The connectors and filling hoses must be visually
inspected for mechanical damage before each use and
replaced if damaged.
•
The seals of a manifold are naturally subject to
mechanical and ageing-related wear and tear. The
manifold must therefore be checked regularly by the
user for leaks.
•
If any valves are leaking, the piston must be replaced
(M4-6-04-R/10).
•
If the sight glass is leaking or scratched, it must be
replaced immediately. The replacement parts are
available as a service kit (M4-6-11, Part no. 4491018)
along with a removal tool (M4-6-11-T, Part no. 4493169).
Use the tool to remove the existing brass screw-ring and
then remove the gasket and sight glass. Insert the
replacement gasket and sight glass, and then screw in
the brass screw-ring with the tool. Care must be taken
not to over-tighten the screw-ring in order to prevent
damage to the glass. It should be tightened with a torque
between 3 Nm and 6 Nm.
