Vetus MTC30 Manuel 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 flexible ny-
lon tube or hose, so that it can move freely. These 2 sections of flex-
ible 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 tub-
ing by using a saw (to pre-
vent sawdust from entering
the hydraulic system, which
will invariably cause prob-
lems) 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 support
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 spanner:
- Straight screw-in connector
- T-screw connector
- Intermediate connector
- T-piece
- Right angle screw-in connector

• 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 during scre-
wing the fitting in!
Also make sure that the internal sheathing of the tubing is not
squeezed while tightening the screw.
