Consider installing the following additional components:

•Ball valves—Install ball valves between the connection of the water hoses and the facility water supply to enable you to easily turn off the facility water to the MCS G2 unit for any reason. If you do not install ball valves, water will drain from the facility piping when you disconnect the hose.

•Filter and bypass—Install a filter to aid in the quality of water entering the MCS G2 unit. Install a bypass for the filter to aid in the operation and cooling of your equipment.

•Pressure reducing valve—Install a pressure reducing valve if the pressure of your MCS G2 unit is over the maximum operating pressure of the MCS G2 , approximately 100 psi (6.9 bar).

For more recommendations and installation examples, see the HP Modular Cooling System G2 Site Preparation User Guide on the HP website (http://www.hp.com/go/rackandpower).

Orientation of the hose

The hoses have swivel nuts on both ends, making it difficult to differentiate which end connects to the MCS G2 and which end connects to your facility water. Mechanically, you can connect either end to either location.

For easy installation, connect the end with the clam shell to your facility.

Removing the cap from the T-fitting on the MCS G2 unit

Determine if you are going to install the main hoses up through a hole in your raised floor or if the hoses will lie on top of your floor.

•If you are going to route your hoses through a hole in a raised floor, use the cap wrench to remove the cap from the bottom legs of the T-fittings, and be sure the caps are secure on the side of the T-fittings.

•If you are going to lay your hoses across the top of the floor, use the cap wrench to remove the cap from the side arms of the T-fittings, and be sure the caps are secure on the bottom of the T-fittings.

Attaching the main hoses to the MCS G2 unit

1.Attach the main hoses to the appropriate side of the T-fitting on the MCS G2 unit, and hand tighten.
