APC NetworkAIR™ AFX 1

Standard FeaturesCabinetThe 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 conve-nient quarter-turn fasteners. The access doors for the electronic con-troller and electrical panel can be opened without interrupting the operation of the unit.

Evaporator Coil/Drain PanThe AFX utilizes dual distributors on one circuit of the refrigeration system. During dehumidification the smaller distributor is turned off effectively reducing the active cir-cuits of the evaporator coil. During this mode of operation the evaporat-ing temperature is decreased, resulting in a lower coil surface temperature. This reduction of the coil temperature decreases the sen-sible heat ratio of the coil allowing a greater percentage of moisture removal. Additionally, the warmer air leaving the inactive circuits of the evaporator coil blends with the near saturated air from the active circuits raising the dry bulb temper-ature of the blended air well above saturation. Evaporator coil is 1/2” rifled, copper tube, with raised, lanced, rippled, aluminum fins. Condensate pan is constructed of stainless steel. Evaporator is config-ured as a “V” coil.

Electrical PanelThe electrical panel contains the contactors, starters, overload pro-tection devices, and input power disconnects. Each wire (except jumpers) is numbered every 3” (80mm), or color coded to facilitate circuit tracing when installing and servicing the unit. Each AC power circuit is individually branch circuit fused on all three phases. All com-pressor and motor devices are thermally and short circuit pro-tected. The electrical panel is easily accessible from the front of the unit. An emergency cool override switch can be manually activated to initiate cooling and a field wired thermostat can be utilized to control cooling operation. All electrical compo-nents are UL-listed and -recognized and all wiring conforms to NFPA 70 (NEC) and UL 1995 requirements.

Fan/Motor SectionThe NetworkAIR AFX includes multiple, centrifugal blower assem-blies that have been engineered for quiet, reliable operation. Lower blower speeds reduce noise and extend belt and bearing life to 200,000L10 hours. Permanently lubricated bearings, a single-belt variable pitch drive, and an adjust-able motor base all ensure dependable operation. In addition, the return air is evenly distributed across the cooling coil.

Refrigeration System and CompressorThe refrigeration system operates under an automatic microprocessor controller for greater efficiency and accuracy. The heavy-duty compres-sor is designed for year-round operation with a 15-year life expectancy. The performance of the refrigeration system is enhanced by use of Scroll Compressor Technol-ogy. Vibration in the system is greatly reduced by elimination of the reciprocating masses found in the semi-hermetic compressor. Risk of refrigeration leaks at compressor gaskets are eliminated with the scroll compressors fully welded hermetic shell. The design of the scroll is more tolerant to liquid flood back than the traditional reciprocating compressor. Power consumption at full load is greatly reduced with higher EER’s of the scroll. In addition reliability is enhanced due to the fewer moving parts required using scroll technol-ogy. The end result is a refrigeration system that offers the user opti-mized performance, efficiency, and reliability.

Main Power DisconnectA nonautomatic main power circuit breaker disconnects all high voltage power to the unit if necessary. The disconnect switch is accessible without removing the electric box cover.

Optional Features

Air FilterThe filtration of conditioned air is extremely vital to maintaining the clean, particle-free environment required by electrical equipment. The system uses 30% efficient (100 microns) (ASHRAE 52.1-92), 4” (102 mm) deep filters, with full depth filter pleats. Deeper filters produce a lower pressure drop, requiring less energy during normal operation. Filters are replaceable through the front of the upflow unit, through the top of the downflow unit, and from either side of the fil-ter box on the back of the upflow rear return unit.

HumidifierThe humidifier utilizes a pure steam generator specifically designed for hi-tech area environmental control. The pure steam eliminates contami-nating mineral deposits, bacteria, white dust and excessive humidity. The humidifier requires little or no scheduled maintenance. Automatic flushing combined with an indicator that signals when the canister is to be change changed, ensure mainte-nance free operation.

Electric ReheatA three-phase electrical resistance heater sized to offset the sensible cooling capacity in the dehumidifi-cation mode is incorporated in each NetworkAIR AFX. The reheat ele-ments are low watt density sheathed components. The reheat is three phase to provide even phase load-ing. Reheat elements are electrically and thermally protected. 20-27kW (6-8 ton) models come with one stage standard with a max-imum of two stages available. 34-98kW (10-28 ton) models come with 2 stages.

CondenserWater- 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 vac-uum furnace and comply with ASME pressure vessel code. Pres-sure rating is 450 psi (3100 kPa).

Water-Regulating ValveThe Water-and Glycol systems maintain proper performance by sensing refrigerant discharge pres-sure and regulating the among of water or glycol supplied to the con-denser. A two-way or three-way valve is available. The standard valve pressure rating is 150 psi (1030kPa).

Discharge Duct CollarA 1” (25.4 mm) duct flange is shipped loose from the factory for field installation to provide conve-nient connection to external ductwork for either supply or return as needed.

Secondary Drain PanSystems are provided with two drain pans. The primary stainless steel condensate drain pan lies directly under the cooling coil. A secondary emergency drain pan provides additional protection by catching and water before it reaches the subfloor and becomes a problem.

FirestatA firestat is available for factory installation in the air stream of the unit. If the return air temperature reaches 125°F (52°C), an audible and visual alarm on the micropro-cessor will be activated and the unit will immediately shutdown.

Smoke DetectorThe factory-installed smoke detec-tor is designed to sense smoke in the return air stream. Upon detec-tion of smoke, an audible and visual alarm on the microprocessor will be activated and the unit will be imme-diately shutdown.

Condensate PumpThe factory-installed and wired condensate pump will pump 36 gal/h (0.06 L/s) at 15 ft. (4.6 m) head.

Remote Relay ShutdownShutdown of the NetworkAIR sys-tem can be done remotely by a factory installed relay. The relay can be ordered with a 24V, 120V, or 240V coil. The relay must be pow-ered by others to disable the NetworkAIR system.

Reheat/Humidity LockoutWhen facilities have limited backup power capacity, this lockout pre-vents the operation of electrical loads that are not essential for con-tinued site operation.


Optional Features

Redundant Group ControlAllows 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.

Remote Display PanelThe microprocessor controller allows facility or building mainte-nance personnel to evaluate and control the unit from up to 50ft. away from the unit, without having to enter the secured space.

Remote Sensor(s)Environmental sensor(s) can be strategically placed, up to 50ft. from the unit to better meet the site’s cooling needs. The sensor must be positioned to permit air movement across the sensors.

Hot Gas ReheatHot gas reheat is optional on water- and glycol-cooled systems. The copper tube, aluminum fin hot gas reheat coil maintains the leaving dry bulb temperature when the sys-tem is in dehumidification mode. The coil is controlled by the proces-sor through a factory piped and wired three-way heat reclaim regu-lator and check valve.

Hot Water Reheat (Modulating)A 2- or 3-way modulating control valve controls hot water reheat. The system is supplied with a factory-installed copper tube and an alumi-num fin hot water coil.

Optional Blower/Motor HPAn optional 5HP motor can be used for increased CFM or to accommo-date special air filters, high external static pressure, etc. while maintain-ing the standard CFM rating.

High Efficiency Filter(s)Pleated final filters with an efficien-cies of 45% or 65%, 4” (102mm) deep, allow for the removal of a greater percentage of airborne par-ticulate contaminates.

Prefilter(s)The prefilters capture large airborne particulate contaminates, thereby extending the life of the high-effi-ciency filter. Prefilters are 1” (25mm) deep and easily disposed.

Hot Gas BypassAn auxiliary side-port hot gas bypass circuit. The activation of the hot gas bypass circuit will maintain the evaporator coil temperature dur-ing low load conditions. This optional feature will minimize com-pressor cycling and temperature fluctuations.

3-Way Valve Flow SwitchA Single-Pole, Double-Throw flow switch can be wired to energize one device and de-energize another device powered from the same source when fluid flow either exceeds or drops below the set flow rate.

PlenumAir discharge plenums are available with upflow configurations. Heights are offered in 20” (508mm) and 24” (610mm). Manually adjust-able, double deflecting grilles are provided on 3 or 4 sides.

Air deflectorA field installed air deflector runs the length of the unit and attaches to the floorstand for changing air direction from vertical to horizontal.

FloorstandThe floorstand raises the unit above the subfloor to match the height of the raised floor. Heights are avail-able (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 pro-vided by threaded pedestals. Vibration absorbing pads are included. The floorstand, pedestal, and pads ship loose. In areas where earthquakes are a concern, seismic floorstands are available in 12” (305mm), 18” (457 mm) and 24” (610 mm) heights.

CastersA set of 6” plated rolling caster wheels are available for handling of equipment.

Environmental Monitoring UnitA stand-alone unit performs contact monitoring and continuous temper-ature and humidity sensing through two probes (one included). The unit is controlled by available web, con-trol console, or SNMP interface with a network connection. In the event of an environmental anomaly, notification is sent via e-mail or SNMP. The unit is 18.25” x 9” x 2.75” (464mm x 229mm x 70mm).

Environmental Management SystemA browser-accessible, 1U, rack-mountable appliance allows monitoring of environmental condi-tions. Monitoring of one temperature, one humidity, and one vibration sensor ship standard. When conditions change, notifica-tions are sent via email to appropriate personnel. The EMS provides 8 input contacts, 2 output relays, and controllable power out-lets for defining actions remotely should conditions warrant it.


Optional Features

ModBus/JBus GatewayThe Gateway translates transmis-sion protocol from the system’s network into ModBus/JBus com-munication protocol. One gateway can support up to 16 units.

OHE DisconnectA non-fused disconnect switch may be wired to an outdoor heat exchanger to disconnect high volt-age power if necessary.

Custom Alarm Contact ClosuresEach unit is equipped with dry con-tact closures. Upon activation of the associated alarm, a discreet Nor-mally open or Normally closed contact is available for remote mon-itoring of that discrete alarm.

Downflow Return DuctA return duct the length and width of the unit may be field installed on a downflow unit to provide conve-nient connection to external ductwork.


Microprocessor Controller

Microprocessor Controller The microprocessor controller is standard on the main module of each system. The controller pro-vides 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.

StatusComplete status monitoring is pro-vided within the status menu of the microprocessor controller. Avail-able information includes:

• Current Temperature/Humidity• Temperature/Humidity Setpoint• Cooling/Heating Status• Humidification/Dehumidification

Status

AlarmsQuick access to any alarm condition is facilitated through the menu structure. The alarm key acts as a hot key providing immediate access to the alarm display menu. Presence of a new alarm will sound the audi-ble alarm. The red alarm LED on the display panel will remain illu-minated until all alarms have been cleared. The temperature and humidity alarm setpoints are adjust-able. Alarm annunciations include:

• Loss of airflow• Clogged filter• High head pressure• Low suction pressure• High/Low temperature• High/Low humidity

Automatic setpoint crossover pro-tection will prevent the setting of the heat setpoint above the cool set-point and the humidification setpoint above the dehumidification setpoint. Setpoint adjustment can be restricted to only operators with knowledge of the security codes set within the security menu structure.

ConfigurationFlexibility is offered through he use of the configuration menu. Operat-ing requirements are satisfied by changing the configuration set-tings. New configurations are stored in EEPROM and protected from unauthorized tampering by the four-digit security password, selected in the security menu. Con-figuration options include:

• Fahrenheit or celsius display• Compressor minimum on/off time• Power loss restart time delay• Redundant unit grouping• Alarm input polarity• Alarm enable• Temperature/Humidity deadbands• Small room delay

Common Alarm ContactA common alarm relay is installed on every microprocessor. In the event of an alarm condition, the relay will change state. The user can select which alarms change the state of the relay. This feature allows for remote enunciation of alarm status.

Run TimesThe major components within the unit have independent run timers that monitor and store accumulated run hours on the components. The run timers are provided with opera-tor adjustable run time alarms.

SecurityMultiple security levels prevent unauthorized adjustment of impor-tant system parameters. The user may select a four-digit password for setpoint and configuration changes. Should the password be forgotten, APC can provide temporary access.

MonitoringWith the addition of a supervisory network communications card the microprocessor may interface with the locally installed APC remote monitoring and control system. Gateways are available for interfac-ing with building management systems. Please check with APC for compatibility with your building management system.

Cool InhibitPrevents the unit from over-cooling during the dehumidification cycle. If the space temperature falls below a user adjustable setpoint, cooling will become inhibited until the space temperature returns to setpoint.

Cool OverrideA manual toggle switch will allow the compressor to operate in the event of a microprocessor failure. The cool override can be field wired to a snap acting thermostat for cool-ing control.

Remote ShutdownEvents external to the unit, such as activation of a fire suppression sys-tem may require the unit to shut down remotely. Additionally this feature may be tied into a BMS that would allow remote control of the units on/off status.

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.

Room preparation During the design of the room, consideration should be given to the following factors: ease of entry for the system, floor-loading factors, and accessibility of piping and wiring.

The room must be sealed with a vapor barrier to minimize migration of moisture. Polyethylene film (plastic sheeting) is a good vapor barrier for ceiling and wall applications. Rubber- or plastic-based paints should be applied to concrete floors and walls. The room should be thoroughly insulated to minimize thermal loads and make-up air (if required) should be preconditioned to reduce additional temperature, filtration, and moisture loads.

A room using a raised-floor plenum for air distribution should have at least 9" (300 mm) of clear space between the false floor and sub-floor for a finished floor height of 12" (380 mm). Pay special attention to the location of pipe chases, electrical conduits and other obstructions under the floor. These objects can block air circulation and cause loss of air pressure, thus reducing system efficiency and causing hot spots in your room.

Minimum clear space of 18" (460 mm) is to be provided for units over 15 tons (53 kW).

APC should be notified before installation if the unit is incorrect for the application.

Unit location The location of the unit is important for efficient and balanced environmental control in your room. The air conditioner should be located as close as possible to the largest heat load. In rooms having a high aspect ratio, mount the unit along the longest wall to ensure even air distribution. If improperly installed, erratic control or mechanical failure can and will result.



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. Verify that all parts ordered were received as specified and that the unit is the correct size and voltage necessary to fulfill your environmental control needs. Report any damage discovered to the freight carrier. If necessary, contact the APC field service department for help in repairing or replacing damaged parts. While APC is not responsible for damage incurred in transit, we want to make sure that you have no undue delays in your system start-up.

Rigging The unit is manufactured with a formed steel frame for maximum strength and unit integrity. However, as with all electrical and mechanical equipment, you must take care with proper rigging of your unit.

When using a forklift to move the unit, use the shipping skid to protect the bottom of the unit. When using chains, cables or rope to lift the unit, use spreader bars to prevent damage to the finished panel.

Floorstand Install a threaded pedestal into each leg of the floorstand. Use the washer and nut on each panel to tighten against the floorstand leg.

Utility connections All connections are made through the bottom left of the unit (the left side of upflow discharge units) for ease of service connections. Refer to the installation manual for pipe sizes and specific locations for your unit.

Power unit The AFX unit uses 3-phase power for operation. Power connections are landed to a receptacle on either floorstand or sub base. Bring the service cable through the bottom left of the unit and through the bulkhead hole into the electrical box to the circuit breaker provided on the left side of the electrical box. The ground lug is located near the 3-phase high-voltage connector. THE UNIT MUST BE UTILITY GROUNDED OR THE WARRANTY IS VOID.

Humidifier connections The humidifier inlet connection point is provided with the equipment. A 1/4" (6.4mm) compression connection is supplied with the unit.

Condensate drain Condensate from the evaporator pan is collected and discharged by the condensate pump to a 7/8" (22.2mm) fitting for field connection.



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. DO NOT use completely demineralized water with the humidifier. The minerals allow the electrode principle to work.

6. DO NOT use a hot water source. Doing so will cause deposits that will eventually block the fill valve orifices.

7. Water supplies with high conductivity (above 800 mW) must be preconditioned for proper operation and longevity of the humidi-fier.

Water supply A 16- to 20-mesh strainer must be installed in the water supply to the water units to prevent clogging of brazed plate condenser. This is a field item.Also recommended on glycol units.
