Chapter 3: Installing the Heat-Transfer Door
To connect the chilled water supply to the Heat-Transfer Door, complete the following steps:
1. Open the HTD so it’s at a 90° angle from the enclosure.
2. If the IT enclosure is on a raised floor, remove the raised floor tile that the supply and return water hoses will pass through and
pull up the hoses to provide slack.
NOTE: We recommend that you place the hose cut-out in the raised floor tile on the tile edge so that the tile can be removed
without having to disconnect the hoses. If this is not possible, then make a hose cut-out in the interior of the raised floor
tile. The raised floor tile will remain in place and the supply and return hoses must route through the hose cut-out in the
interior of the raised floor tile before attaching to the HTD.
CAUTION: When using the External Right-Angle Hose Kits to pass the hose under the enclosure frame, the clearance between
the bottom of the HTD and the floor must be at least 2.125" (5.4 cm).
3. Attach the male supply hose coupling to the female supply coupling on the HTD. To attach the supply hose, complete the
following steps:
a. Align the male supply hose coupling with the female supply coupling on the HTD.
NOTE: If you misalign the couplings, it will be difficult to connect the hose.
b. Move the collar on the female coupling on the HTD upward.
c. Insert the male supply hose coupling. Exert upward pressure until the female collar moves downward and locks in place with
an audible click.
NOTE: After the couplings are engaged but before the collar has locked into place, you can let go of the collar and use both
hands to push the hose upward to lock the couplings.
4. Attach the female return hose coupling to the male coupling on the HTD. To attach the return hose, complete the following
steps:
a. Align the female return hose coupling with the male return coupling on the HTD.
NOTE: If you misalign the couplings, it will be difficult to connect the hose.
b. Move the collar on the female return hose coupling downward and raise the female coupling to the male coupling on the HTD.
c. Exert upward pressure until the female collar moves upward and locks in place with an audible click.
NOTE: After the couplings are engaged but before the collar has locked into place, you can let go of the collar and use both
hands to push the return hose upward to lock the couplings.
3.3.3 Filling the HTD with Water
To fill the HTD with water for the first time, complete the following steps.
CAUTION: Wear safety goggles or other eye protection whenever filling, draining, or purging air from the HTD.
1. Unscrew and retain the caps from both air-purging valves (on bottom-feed models only).
NOTE: The valves (see Figure 3-7) are similar to the valves on bicycle tires. Figure 3-8 shows the air-purging tool (sold separately)
consisting of a long hose (72”/184 cm) and a short extension hose (6”/16 cm).
