     HOSE ASSEMBLY – INSTALLATION GUIDE
 INSTALLATION GUIDE - HOSE ASSEMBLY (CONT)
Proper hose installation is essential for satisfactory performance. If hose length is excessive, the appearance of the installation will be unsatisfactory and unnecessary cost of equipment will be involved. If hose assemblies are too short to permit adequate flexing and changes in length due to expansion or contraction, hose service life will be reduced.
The following diagrams show proper hose installations which provide maximum performance and cost savings. Consider these examples in determining length of a specific assembly.
  REDUCE NUMBER OF PIPE FITTINGS
        • Reduce number of pipe thread joints by using proper hydraulic adaptors instead of pipe fittings.
  USE 45o AND/OR 90o ADAPTORS
        • Route hose directly by using 45° and/or 90° adaptors and fittings.
• Avoid excessive hose length to improve appearance.
     ALLOWING FOR LENGTH CHANGE
        • To allow for length changes when hose is pressurised, do not clamp at bends.
• Curves will absorb changes.
• Do not clamp high and low pressure lines together.
  AVOID TWISTING HOSE
        • When installing hose, make sure it is not twisted.
• Pressure applied to a twisted hose can result in hose failure or loosening of
connections.
    HIGH TEMPERATURE
        • High ambient temperatures shorten hose, therefore ensure hose is kept away from hot parts.
• If this is not possible, insulate hose.
  RELIEVE STRAIN
        • Elbows and adaptors should be used to relieve strain on the assembly, and to provide neater installations which will be more accessible for inspection and maintenance.
