JOHNSON CONTROLS
Features and Benefits (Cont’d)
Easier Maintenance
• Large, intuitive operator interface makes for quick set up and easier diagnostics. It is
on the external panel for easy viewing.
• Operator interface for optional VFD on the external panel.
• Easy access to important components through hinged doors for easy maintenance.
• Easily accessible components out of the air stream allow adjustment of components,
including expansion valves, while unit is operating.
• Easy lter access for inspection, removal, and replacement.
• Internally trapped condensate drain cleanout with easy access.
• Available BACnet
®
communications with Building Automation System (BAS) al-
lows for easier control of larger installations.
• Emergency stop input.
Indoor Air Quality
• Condensate drain pan sloped in all directions to the drain point.
• Stainless steel drain pan standard
• High efciency lters option with pre-lters.
• Evaporator and waterside economizer coils surface may be cleaned from air entering
side as well as air leaving side.
• Easy access to internally trapped condensate drain cleanout.
• Matt faced berglass insulation.
Quieter Acoustic Performance
• Plenum fan with backward inclined airfoil blades provides required airow at a low-
er sound power level compared to the most competitive units.
• Unique placement of internal components minimizes amount of acoustic energy
leaving the unit.
• Supply fan and motor assembly mounted on a frame and isolated with springs.
• Optional discharge plenum congurations allow horizontal supply air discharge,
minimizing the outlet sound and pressure losses.
• Optional inlet plenum conguration minimizes sound escaping the unit inlet.
• Multiple scroll compressors, due to their smoother ow and stepped operation, mini-
mize the sound associated with the refrigerant system.
• The compressors are located out side air stream, including all the refrigerant piping
and condenser water piping.
