Lay hoses side-by-side as they run between the heat exchanger and the pump unit
manifold, and allow the hoses to freely move. Leave enough slack in the hoses
below the rear door so that no pressure is exerted on the mated couplings when
the hoses are connected and operating. When you route hoses, avoid sharp bends
that cause hose kinks and avoid hose contact with sharp edges.
Non-raised floor hose requirements and management
In data centers without a raised floor, straight hose assemblies cannot make the
sharp bend to exit between the floor and the rack door without kinking the hose.
Hose assemblies with right-angle metal elbows are needed to route the hoses along
the floor. Make the 90° turn upwards within the gap between the bottom of the
heat exchanger and the floor surface, and then connect to the heat exchanger
couplings (see Figure 31 on page 88).
