INSTRUCTIONS FOR THE INSTALLATION OF HOSES AND CONNECTORS
Visual check of hoses and connectors: if one of the following conditions occurs, the hose must be im-
mediately disconnected and replaced:
•
movement of the connector on the hose;
• there are damage, cuts or abrasions on the surface;
• hardening or stiffness of the hose, burned parts or cracks due to heat;
•
cracks, damage or corroded parts on the connector;
•
l
eakages from the hose or connector;
•
the hose has permanent folds, squashed or twisted parts;
• presence of bubbles, softening and wear of the external surface.
Pre-installation inspection: before installing a hose it is necessary to check the conditions of the pipes.
First of all check if the type, the size, the reference code and the length are correct and then make sure that
there are no impurities, obstructions, bubbles, external layer peeling-off or other visible defects.
Installation:
Do not twist the hose, otherwise it could break due to pressure.
Consider a proper radius of curvature in order to avoid the bending or breaking. If the radius of curvature
is lower than the minimum radius of curvature allowed, the life of the hose is considerably reduced.
The pressure can change the length of the hose, up to + %. Therefore it is advisable to consider a length
which is higher than the required one in order to compensate for such changes.
