Installation
Figure 11 — Incorrect Vertical Hose Installation
Incorrect vertical hose installation shows an incorrect hose installation. In
this configuration the hose is installed without an elbow and with an
elevation greater than 7 feet off the ground. This creates excessive stress at
the hose coupling connection, causing the hose to stretch and separate from
the coupling. It also causes the hose to crimp at the ground.
The following figures illustrate the correct and incorrect methods for
installing hose in a horizontal and vertical combination application.
Figure 12 — Correct Horizontal/Vertical Installation
Correct horizontal/vertical installation shows a correct horizontal/vertical
hose installation. In this configuration, correct installation techniques
followed are:
• the hose is installed with elbows at both connection ends
• the vertical run of hose is less than 7 feet
• the hose is adequately supported by more than half its total length on
the ground
These items minimize the stretching and separation at the hose-coupling
interface and also the crimping of the hose at the ground.
