ii APC NetworkAIR™ AFX
Overview The APC NetworkAIR AFX computer room air conditioning system provides a quiet, efficient, and reliable solution for heat sensitive equipment areas. Precision environmental requirements now reach far beyond the confines of the traditional data center or computer room to encompass a larger suite of applications, referred to as technology rooms. Critical environment applications include: Room Air Distribution Downflow systems discharge air into the raised floor plenum.
Standard Features Cabinet The frame is constructed of heavy gauge steel for maximum strength. Steel access panels are insulated for quieter operation. The unit has been designed for full service access from the front. The flush mounted panels are removable using convenient quarter-turn fasteners. The access doors for the electronic controller and electrical panel can be opened without interrupting the operation of the unit.
Standard Features Redundant Group Control Allows up to six NetworkAIR units the ability to communicate with each other to automatically switch upon alarm condition, or timed rotation. Can also allow standby units the ability to assist the running system. Condensate Pump The factory-installed and wired condensate pump will pump 36 gal/ h (0.06 L/s) at 15 ft. (4.6 m) head.
Optional Features Condenser Water- and Glycol-cooled systems employ a brazed plate condenser that uses the latest heat transfer technology. Type 316L stainless plates are brazed together in a vacuum furnace and comply with ASME pressure vessel code. Pressure rating is 450 psi (3100 kPa). Water-Regulating Valve The Water-and Glycol systems maintain proper performance by sensing refrigerant discharge pressure and regulating the among of water or glycol supplied to the condenser.
Optional Features Floorstand The floorstand raises the unit above the subfloor to match the height of the raised floor. Heights are available (from 6” (142 mm) to 36” (914 mm)) in 3” (76.2 mm) increments and are adjustable +/- 1.5” (38.1 mm). APC recommends at least 12” (305 mm) high floorstands for their downflow units. Adjustment is provided by threaded pedestals. Vibration absorbing pads are included. The floorstand, pedestal, and pads ship loose.
Microprocessor Controller Microprocessor Controller The microprocessor controller is standard on the main module of each system. The controller provides precision control for the demanding requirements of: • Data centers • Control rooms • Clean rooms • Switch rooms • UPS rooms The easy-to-use display allows the operator to select options from the device’s menu-driven interface to control and monitor the connected air conditioning system.

Guidelines for Installation The AFX provides reliable, accurate temperature and humidity control of computer rooms, laboratories, and other environments that require close tolerance control. The unit incorporates the latest system design innovations to provide you with optimum efficiency, reliability, and accuracy of control. The AFX system will provide years of trouble-free service, when installed and maintained by technically qualified personnel.
Guidelines for Installation Service access At least 24" (610 mm) of clear space must be left in front of the unit for routine service (filters, humidifier). We strongly recommend approximately 32" (813 mm) clearance in front of the unit. Receiving the unit Your AFX unit has been completely tested and inspected prior to shipment. To ensure that you have received the unit in excellent condition, perform a careful inspection of the crating and the unit immediately upon receipt.
Guidelines for Installation Water supply to humidifier 1. The humidifier fill valve orifice is sized for supply water pressure from 15 PSIG (103.4 kPa) to 150 PSIG (1034 kPa). 2. For cases above 150 PSIG (1034 kPa), install a pressure-reducing valve in the water feed line to the unit. 3. With extremely dirty or muddy water sources, proper filtration is required on the unit’s incoming water line. 4. DO NOT use softened water with the humidifier. Softened water is too conductive. 5.
