General Information Introduction The NetworkAIR RM Air Distribution Unit works with an existing precision A/C system to deliver cool air to the equipment contained in a NetShelter enclosure or other 19" EIA-310-D enclosure with an open or removable floor. The Air Distribution Unit, installed at the bottom of the enclosure, pulls supply air directly into the enclosure, thereby preventing the conditioned air from mixing with warm ambient air before it reaches the equipment.
Safety Information Disconnect power to the enclosure before installing the Air Distribution Unit. Failure to do so may result in personal injury or damage to equipment. Warning Check to see that a fan guard is securely in place over each of the air inlet openings. Do not apply power to the unit until the installation is complete. The Air Distribution Unit contains moving parts, which are potentially hazardous when operated outside of the enclosure. Keep fingers and clothing away from the fans.

Before you begin Receiving inspection Inspect the package and contents for shipping damage, and make sure that all parts were sent. Report any damage immediately to the shipping agent, and report missing contents, damage, or other problems immediately to APC or your APC reseller.
Overview Tools required You will need the following to install the Air Distribution Unit: • Pencil • Saw or other tool for cutting a hole in the raised floor tile(s) (raised floor application only) • Caged nut tool (provided) • 7-mm spanner or nut driver • Phillips screwdriver Overview of the installation procedure The Air Distribution Unit can be installed in both raised-floor and non–raised-floor applications.
Installation Installing the guide and rail assemblies To install the guide and rail assemblies: 1. Remove the bottom panel of the enclosure. 2. Locate the position for the guide and rail assembly on each of the four vertical mounting rails of the enclosure, at the second U from the bottom. (To identify a U on a mounting rail, see the documentation provided with your enclosure.) 3.
Installation 5. From the front of the enclosure, attach the front guide and rail flanges to the outside of the vertical rails using four, M 6 × 12 mm, Phillips pan-head screws and four plastic washers. Push and hold each bracket firmly toward the outside of the enclosure when tightening screws. 6.
Installation Installing the duct assembly Note For non-raised floor applications you must remove the bellows for proper operation. Pull apart the hook-and-loop tape holding the bellow to the duct. 1. With the slotted holes positioned to the rear of the enclosure, place the duct and bellows assembly onto the guide and rail assemblies. Slide the assembly forward as far as it will go. 2. Locate the holes in the bottom of each rail flange that align with the center of the duct and bellows assembly slots.
Installation 3. Fasten the duct and bellow assembly to the rail assemblies using two, M6 ×12mm, Phillips pan-head screws and the caged nuts installed in last step. For non–raised-floor applications proceed to “Installing the fan assembly” on page 11.
Installation Cutting the opening in the raised-floor tile(s) (raised floor applications only) 1. Using the inside edge of the duct opening as a template, mark the location for the opening to be created in the raised floor tile. 2. Move the enclosure to provide access to the floor tile(s) for cutting. 0 3. Remove the floor tile(s) and cut an opening in the tile(s) at the location marked. Use tools that will provide a clean, accurate cut. 4.
Installation 7. Move the enclosure to its original position and stabilize. 8. Attach the bellows to the floor using the hook-and-loop tape. Installing the fan assembly 1. Place the filter in the filter housing of the duct. Place the filter so that the arrow on the filter points upward to match the intended air flow of the air distribution unit.
Installation 2. With the front of the fan assembly facing the front of the enclosure, insert the rails on the sides of the fan assembly into the guides on the guide and rail assemblies. 3. Slide the fan assembly toward the rear of the enclosure until the rails lock in place. 4. Tighten all the screws holding the guide and rail assemblies to the vertical rails. 5. Close the front door of the enclosure and, from the rear, push the fan assembly fully forward until it touches the front door of the enclosure.
Installation Installing the blanking plate Note If the 3U position immediately above the Air Distribution Unit is open, you must cover it with the blanking plate provided for proper operation and maximum cooling. 0 1. Using the caged nut tool, install the caged nuts in the corresponding mounting holes on the inside of each vertical rail. 2. Attach the blanking plate, with the flange located at the bottom, using the four, M6 × 12 mm, Phillips pan-head screws and four, plastic washers.
Installation Connecting to the power supply To supply power to the Air Distribution Unit: 1. Using one of the supplied power cords, connect the female end to one of the input sockets on the rear of the unit. Plug the male end into a UPS or other socket that provides protected power. A AC B 1 FAN 2 2. To provide redundant power to the unit, use the remaining socket to connect to a second source of protected power. 3. Cords may be bundled and tie-wrapped to provide clearance for other components.
Operation and Maintenance Start-up Warning Before applying power to the Air Distribution Unit, remove any debris that may located in or near the fan rotors. Failure to remove debris can result in damage to equipment or cause bodily harm. Do not apply power to the unit with the air intake fan guards removed. Check operation of the unit: 1. Apply power to Fan 1 by pressing the corresponding switch on the rear of the unit. FAN AC A B 1 2 2. Air should be flowing out of the Air Distribution Unit. 3.
Operation and Maintenance When to use only one fan Depending on your enclosure’s height and the heat output of installed equipment, you may choose to operate only one fan, thus reducing energy consumption. Smaller enclosures often require only one operating fan. You may also choose to operate both fans during normal operation, and turn off one fan in the event of a loss of utility power. This will conserve run-time on the battery of the UPS.
Operation and Maintenance replace with new filter (3-pack—ACF001RF). Note In some situations the air filter will need to be accessed from the front of the enclosure because of interfering wires and cables. To access the filter from the front, slide out and remove the fan assembly.
