Guide Specifications
APC NetworkAIR™ FM-DX 45
L. EVAPORATOR FREEZE PROTECTION
1. Suction pressure shall be actively monitored and controlled to eliminate the risk of
condensate freeze-up on the evaporator.
M. PREDICTIVE FAILURE WARNINGS
1. Several components within the unit shall provide a warning via the microprocessor
interface that service is needed prior to failure occurring.
N. HIGH RETURN AIR TEMPERATURE CAPABILITY
1. All NetworkAIR FM units shall be equipped to handle the high return air temperatures
associated with today’s high density applications.
O. REFRIGERANT CHARGE ISOLATION
1. For compressor protection, the NetworkAIR FM shall utilize charge isolation and crank
case heaters during compressor off-cycles. This shall eliminate the threat of liquid
refrigerant migration that could lead to compressor slugging and lubrication issues.
P. STEAM GENERATING HUMIDIFIER
1. Humidifier shall be able to modulate capacity. The humidifier shall be self-contained,
steam-generating type, factory piped and wired, with disposable cylinder and automatic
solid-state control circuit. The humidifier shall require little or no scheduled maintenance.
Humidifier canisters shall be replaceable. The humidifier controller shall communicate
directly to the microprocessor controller and provide complete status and control at the
operator interface.
Q. SCR ELECTRIC REHEAT
1. Reheat elements shall be low watt density, wired for three-phase, loaded equally on all
three phases and shall be electrically and thermally protected by both automatic and
manual reset thermal cutouts. Reheat capacity shall be _______ MBH, _______ kW, SCR
controlled. Reheat coils shall be stainless steel, fin tubular construction.
R. 30% FILTERS
1. The air filters shall be 30% efficient per ASHRAE Standard 52.1-92, UL Class 2. The full
4” (102 mm) deep, pleated filters shall be replaceable from the front of the unit.
S. HIGH LIFT, DUAL FLOAT CONDENSATE PUMP
1. Factory installed and wired condensate pump shall pump 60gal/h (0.06 L/s) at 60ft (18.3
m) head.
