Crystal CPF High Pressure Hose and Fittings - Manual (Page 9)

Crystal Safety Guide for Using Hose Assemblies and Fittings  7
Proper Connection of Ports
Proper physical installation of the Hose Assembly requires a correctly installed port connection insuring that no twist or torque is transferred to the Hose As-
sembly when the Fittings are being tightened or otherwise during use.
External Damage
Proper installation is not complete without insuring that tensile loads, side loads, kinking, flattening, potential abrasion, thread damage, or damage to sealing
surfaces are corrected or eliminated.
System Checkout
All air entrapment must be eliminated during hydraulic applications, and the system pressurized to the maximum system pressure (at or below the Hose
Assembly maximum allowable working pressure (MAWP)) and checked for proper function and freedom from leaks. Personnel must stay out of potential
hazardous areas while testing and using.
Routing
The Hose Assembly should be routed in such a manner so if a failure does occur, the escaping media will not cause personal injury or property damage.
In addition, if fluid media comes in contact with hot surfaces, open flame, or sparks, a fire or explosion may occur.

HOSE ASSEMBLIES AND FITTING MAINTENANCE AND REPLACEMENT INSTRUCTIONS
Even with proper selection and installation, Hose Assembly life may be significantly reduced without a continuing maintenance program. The severity of the
application, risk potential from a possible Hose Assembly failure, and experience with any Hose Assembly failures in the application or in similar applications
should determine the frequency of the inspection and the replacement for the Products so that Products are replaced before any failure occurs. A mainte-
nance program must be established and followed by the user and, at minimum, must include
Visual Inspection, Functional Test, Replacement Intervals,
Hose Assembly Inspection and Failure, and Elastomeric (o-ring) Seals as outlined in the sections below.
Visual Inspection–Hose Assembly/Fitting
Any of the following conditions require immediate shut down and replacement of the Hose Assembly:
•
Fitting slippage on Hose Assemblies;
•
Damaged, cracked, cut or abraded cover (any reinforcement exposed);
•
Hard, stiff, heat cracked, or charred Hose Assemblies;
•
Cracked, damaged, or badly corroded Fittings;
•
Leaks at Fitting or in Hose Assembly;
•
Kinked, crushed, flattened or twisted Hose Assemblies; and
•
Blistered, soft, degraded, or loose cover.
