In another example, for a rack that is installed at the same time as a heat
exchanger, or in cases where a rack is moved to install new floor tiles under it,
each heat exchanger still requires a special cut 0.6 m
× 0.6 m (2 ft × 2 ft) floor tile.
However, the floor tile is positioned completely within the footprint of the rack. A
modified cable opening or independent hose cutout is used.
Flexible hoses that each contain a right-angle elbow are used to route the hoses
under the rack in a large loop to allow hose movement when the door is opened
and closed. Figure 24 on page 54 and Figure 25 on page 55 show how to route
hoses under the rack with enough hose length to allow the hose to move freely as
the door is opened and closed.
Note: Existing tile cutouts for electrical or other cables can also be used for the
hoses, if enough space is available.
