Note:
1. When an even number of hose assemblies are
connected together, coupler conguration
(male vs. female) are reversed. Always connect
an odd number of hose assemblies together to
maintain proper coupler conguration.

2. Make sure all QD’s are properly assembled.
Note: If “screw on” QD’s are used, use pliers to
grip female ring when tightening QD’s.
3. If leaks at “A” continues:
