Vetus MTC30 Instructions D'installation page 11

When the installation uses copper or steel tubes, they must be
of the 'internally cleaned' type.
When fitting copper or steel tubes, avoid long straight sections;
the length of the tube is affected by ambient temperature.
The cylinder must always be connected with 2 lengths of flexi-
ble nylon tube or hose, so that it can move freely. These 2 sec-
tions of flexible nylon tube or hose should each have a length of
at least 50 cm and be fitted with a large bend radius.
After installation, blow through the piping with nitrogen or com-
pressed air (never use water!) to check for blockages and to
remove any dirt.
The minimum bend radius of nylon tubing is:
- 50 mm (nylon tubing 6 mm l.D., 8 mm. O.D.)
The minimum bend radius for nylon hose is:
- 75 mm (nylon hose 6 mm l.D., 10 m O.D.)
- 90 mm (nylon hose 8 mm l.D., 12 m O.D.)
Always secure the hose or tubes with brackets; distance
between brackets about 60 cm.
Always cut the tube or
hose with a sharp knife.
Never cut off piping or
tubing by using a saw (to
prevent sawdust from
entering the hydraulic
system, which will invari-
ably cause problems) or
by shearing (since this will
cause excessive tube
deformation).
After cutting off copper or steel pipe sections, remove the burrs.

Installation of nylon tube/ hose into the connection
• Nylon tube (6 mm l.D., 8 mm O.D.)
After cutting the nylon
tube, fit the coupling
nut and olive on the
tube and fit the sup-
port sleeve inside the
tube.
• Nylon hose (6 mm l.D., 10 mm O.D.)
After cutting the nylon
hose, fit the coupling
nut and olive on the
hose (check that it is
properly positioned in
relation to the end of
the hose ) and push
the support sleeve
into the hose.
Screw up finger tight
and then use a span-
ner:
- Straight screw-in connector
- T-screw connector
- Intermediate connector
- T-piece
- Right angle screw-in connector : 2 turns
• Nylon hose (8 mm l.D., 12 mm O.D.)
1 After cutting the nylon hose screw the socket onto the hose,
anti-clockwise, and stop when the hose is approx 1.5 mm
protruding.
2 Apply some oil to the hose connector fitting and screw it into
the socket. Take care that the inner tube not gets twisted dur-
ing screwing the fitting in!
Also make sure that the internal sheathing of the tubing is not
squeezed while tightening the screw.
