INSTALLATION INSTRUCTIONS CONTINUED
Installation Guide
1. Use elbows and adapters in the installation to
relieve strain on the assembly, and to provide easier
and neater installations that are accessible for
inspection and maintenance. Remember that metal
end fittings cannot be considered as part of the
flexible portion of the assembly. 2. Install hose runs to avoid rubbing or abrasion.
Clamps are often needed to support long runs of hose or
to keep hose away from moving parts. It is important
that the clamps be of the correct size. A clamp that is
too large will allow the hose to move in the clamp
causing abrasion at this point.
3. In straight hose installations allow enough slack in
the hose line to provide for changes in length that will
occur when pressure is applied. This change in length
can be from +2% to -4%. 4. Do not twist hose during installation. This can be
determined by the printed layline on the hose. Pressure
applied to a twisted hose can cause hose failure or
loosening of the connections.
5. Keep hose away from hot parts. High ambient
temperature will shorten hose life. If you cannot
route it away from the heat source, insulate it. 6. Keep the bend radii of the hose as large as possible to
avoid hose collapsing and restriction of flow. Follow
catalog specs on minimum bend radii.
