made.
Features/Benefits
• Most efficient rooftop line for
cooling using scroll compressor
technology
• Most efficient rooftop line for
heating using dimpled heat
exchangers on all units
• High reliability — non-corrosive
condensate pans, prepainted
cabinets and primed interior
panels, and all units are fully
protected by internal safeties
• Quietest operation — all
compressors mounted on
independent vibration isolators.
Standard, belt-driven evaporator
fan motors on all units
• Ease of maintenance achieved by
self diagnostics on the Integrated
Gas Controller (IGC), optional
direct digital controls, standard
size filters, tool-less filter access,
simple compressor access,
permanently lubricated fan
motors, optional disconnect
switch, optional 115-v
convenience outlet, and optional
hinged access panels
