• Direct-spark ignition enhances efficiency

Serviceability

• Isolated compressor compartment allows performance check during normal compressor operation without disrupting airflow
• Slide-out blower allows quick belt tensioning, adjustment or replacement and makes cleaning the blower easier
• Accessible gas compartment provides generous space to access all gas components, making analysis and service easier
• Optional hinged access panels provide quick access to components and protect panels and roof from damage during servicing
• Full-perimeter base rail provides greater structural integrity, so the unit is easier to handle when rigging and transporting
• Fork slots on three sides make it easy to pick up and transport units from almost any angle
• Independent motor mount allows for easy and efficient service access without removing the top panel
• Environ™ Coil System on 7.5 to 25-ton standard and high-efficiency gas/electric and electric/electric units reduces the time necessary to clean the condensing coil

Reliability

• Landmark units with the most popular features and configurations are stocked and ready for fast delivery or pickup at commercial depots across North America
• Pre-defined supply fan motor/drive combinations make selecting components to meet static and airflow requirements quick and easy
• Thermostatic expansion valves on high-efficiency models and fixed orifice on standard-efficiency models
• Environ™ Coil System provides reliable operation in a wide range of applications
• Scroll compressor provides reliable, long-term operation
• Interlink compressor delivers increased reliability and better efficiency

Comfort/IAQ

• Corrosion-resistant, removable, double-sloped drain pan provides application flexibility, durability and improved serviceability
• First stage operation of the optional MSAV® supply fan reduces humidity, providing better space comfort
• Field or factory-installed MERV 8 or 13 filters reduce airborne particles
• Field-installed CO2 sensors reduce levels of CO2 and VOCs by introducing fresh outside air
