Replacing the water manifold in the 8335-GTW or 8335-GTX system

To replace a water manifold, complete the steps in this procedure.

1. If the original manifold had the facility supply and return water hoses that exit at the top of the rack, complete this step to reconfigure the replacement manifold. Otherwise, skip this step.
   1. Unscrew and remove the four nuts of each manifold Z bracket by using a 7 mm nut driver. Remove the three manifold Z brackets and separate the manifold halves.

      

   2. Flip the manifold halves so that the hoses are at the top of the manifold. Ensure that the following criteria are met:
      • The supply manifold half is toward the inside of the rack.
      • The return manifold half is toward the outside of the rack.
      • Align the manifold halves such that the supply manifold half is lower than the return manifold half.

      Align the Z brackets to the manifold. Use the labels on the bracket and the manifold to properly align the brackets. Then, by using a 7 mm nut driver, reattach the manifold z brackets by installing and tightening the four nuts of each bracket.

      Note: The Z brackets are installed on different studs when the manifold is configured with the water hoses exiting the top of the rack than when the manifold is configured with the water hoses exiting the bottom of the rack.

      

2. Align the manifold to the mounting bracket slots, then attach the manifold by using a 7 mm nut driver.

   

3. Connect the facility water supply hose to the manifold hose. Align the two quick connect ball valve fittings, then turn the fittings a quarter-turn to lock the fittings. Then, press the pin on the lever and turn the lever 90 degrees to open one side of the valve. Then, press the pin on the other lever and turn the lever 90 degrees to open the other side of the valve.

   

4. Repeat step 3 to connect the facility water return hose to the manifold hose.
