Installation
Dixon Coupling
• The Dixon coupling (See Figure 7), bolts are to be torqued prior to
charging the hose with water to 40 ft-lbs. DO NOT EXCEED 40 ft-lbs.
(The torque must be applied evenly between the bolts to ensure a
consistent gap on each side of the coupling. Some pinching of the
excess hose in the gap area is considered normal and will not create
a leak or premature failure.)
• Continually monitor and retighten, if necessary, on monthly inspec-
tion intervals.
Figure 7 — Dixon Coupling
The following figures illustrate the correct and incorrect methods for
installing hose in a horizontal hookup application.
Figure 8 — Correct Horizontal Hose Installation
Correct horizontal hose installation shows a correct hose installation. In this
configuration either a 45° or 90° elbow can be installed. This elbow prevents
stretching and crimping of the hose at the hose coupling connection. This
elbow also directs the hose to the ground at an appropriate angle to
minimize the crimping of the hose at the ground or supporting surfaces.
