FEATURES/BENEFITS
One--piece heating and cooling units with low sound levels, easy installation, low maintenance, and dependable performance.

Easy Installation
Factory--assembled package is a compact, fully self--contained, combination gas heating/electric cooling unit that is prewired, pre--piped, and pre--charged for minimum installation expense.
These units are available in a variety of standard and optional heating/ cooling size combinations with voltage options to meet residential and light commercial requirements. Units are
lightweight and install easily on a rooftop or at ground level. The high tech composite base eliminates rust problems associated with ground level applications.

Innovative Unit Base Design
On the inside a high--tech composite material will not rust and incorporates a sloped drain pan which improves drainage and helps inhibit mold, algae and bacterial growth. On the outside metal base
rails provide added stability as well as easier handling and rigging.

Convertible duct configuration
Unit is designed for use in either downflow or horizontal applications. Each unit is converted from horizontal to downflow and includes two horizontal duct covers. Downflow operation is
provided in the field to allow vertical ductwork connections. The basepan seals on the bottom openings to ensure a positive seal in the vertical airflow mode.

Efficient operation High--efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of 14.0, 11.5 EER, and AFUE (Annual Fuel Utilization Efficiency) ratings up to 81.0%.

Energy--saving, direct spark ignition saves gas by operating only when the room thermostat calls for heating. Standard units are furnished with natural gas controls. A low--cost field installed kit
for propane conversion is available for all units.

Low NOx units are designed for California installations and meet 40 ng/J NOx emissions. Can be installed in air quality management districts with a 40 ng/J NOx emissions requirement.

Durable, dependable components
Monoport inshot burners produce precise air--to--gas mixture, which provides for clean and efficient combustion. The large monoport on the inshot (or injection type) burners seldom, if ever,
requires cleaning. All gas furnace components are accessible in one compartment.

Turbo--tubulart heat exchangers are constructed of aluminized steel for corrosion resistance and optimum heat transfer for improved efficiency. The tubular design permits hot gases to make
multiple passes across the path of the supply air. In addition, dimples located on the heat exchanger walls force the hot gases to stay in close contact with the walls, improving heat transfer.

ECM Motor is standard on all models.

Direct--drive PSC (Permanent Split Capacitor) condenser--fan motors are designed to help reduce energy consumption and provide for cooing operation down to 40_F (4.4_C) outdoor
temperature. Motormasterr II low ambient kit is available as a field--installed accessory.
